Housed in a rugged metal case, and sized to fit in your pocket, AVLab TPG is ready to take to any installation job. While there are some exceptional test pattern discs available like Staci Spears …, to properly set up and calibrate a display or projector, it is critical to have a source that can be trusted to put out exact colors and patterns digitally - directly to the display.

Note: Features that require a specific version of firmware AND new features available with updates are indicated with this box on the left of the page. If you do not have at least the version of firmware noted, you need to upgrade to use this feature.

Controls: buttons and the remote

AVLab TPG has three physical buttons:

• Pattern button manually cycles through the most common patterns and can be used if you do not have the remote or software control

• Resolution button cycles through four common video resolutions. This is particularly useful if the AVLab TPG is left in a mode (i.e. 4K) from a previous calibration that the current display does not support. In this case, simply press the resolution button slowly until you get to the “auto” setting and then use the OSD to correctly set output parameters.

• F/W update (recessed) button: if held down while power is initially applied, AVLab goes into firmware update mode.

See updating firmware section of this manual. If F/W version 1.01 or later, simply pressing the button while connected via USB to a PC causes AVLab to enter F/W update (mass storage) mode.

Serial Control and Driver Installation

AVLab can be controlled from a PC for interfacing to a Color Management System like CalMAN or

ChromPure. Before using this feature, drivers must be installed to allow the computer to connect a virtual com port over USB.

** Important – the drivers currently available are unsigned drivers, so for Windows 8 and 8.1, you must first enable unsigned driver installation by following the steps in Appendix B.

Installing the Virtual serial driver:

Automatic installation:

Run the appropriate driver .msi installation package (Windows 7 or XP – use win7 driver for windows 8) prior to plugging in the AVLab TPG to your computer.

After the installer completes, plug in the AVLab TPG.

A good check of proper driver installation is to run device manager, and under ports, AVLab will be listed along with its associated com port.

Manual Installation:

If there is any problem, you can also manually install the driver.

Plug in AVLab via USB to your computer.

Go to Device Manager (Start>Control Panel>System>Device Manager)

Under the “Ports (Com & LPT)” section you will see AVLab listed

Right click on AVLab and choose “Update Driver Software”

Choose “Browse my computer for driver software”

Click on “Browse” button and navigate to the AVLab installation CD where the raw driver .inf files are stored.

Click “OK” and allow the driver to update/install

Test Pattern Explanations

AVLab TPG has three types of test patterns:

• Visual patterns which can be used to roughly set display parameters and check performance and calibration. e.g. Frame and Geometry, Brightness, Contrast, focus, color bars, grey ramp etc.

• Metering patterns that can be used with a simple meter to read and adjust colorimetry e.g. solid primary, secondary and grey colors

• Dynamically generated patterns e.g. when connected to a software package, AVLab can create any color and window size

This is an explanation and how to use the visual patterns.

Frame & Geometry

This test pattern contains two specific test features. The first is a 1-pixel wide box around the very outside of the image. This is used to determine when the entire iScan output image is visible on the display. The arrows along the middle of each edge provide an indication of the amount of overscan (if any). The blue boxes in the center of each quadrant are used for measuring display geometry. The rectangle in the center of the gray boxes should appear square on a 4:3 aspect ratio display, the next large rectangle should appear square on a 16:9 display, the next on a 1.85:1 display, and the largest rectangle should be square on a 2.35:1 display. The blue boxes are also used as an indication that the horizontal positioning of the output image is correct. This is particularly useful to align a video projector and also to visually verify that a TV is not in overscan mode. If the blue boxes are displayed as red instead of blue, then the

Cb & Cr components are reversed. This can be corrected by ensuring that there is an even number of pixels in the sum of the horizontal sync and horizontal back porch.

DVDO AVLab TPG 21 A.04

DVDO AVLab TPG - 4K Test Pattern Generator

Frame/Geometry Test Pattern Displayed Correctly (Image B)

When this test pattern is displayed correctly, it should look like this, with a one-pixel wide white border around the edge of the screen:

DVDO AVLab TPG

Frame/Geometry Test Pattern (Image C)

22 A.04

DVDO AVLab TPG - 4K Test Pattern Generator

As you can see in image C, the test pattern is almost displayed correctly. You can see the 1-pixel wide white border on the top, bottom and left side of the image but not on the right side of the image. By adjusting the horizontal size of this signal to 1360 (rather than 1366), we can get this test pattern displayed correctly on our display.

Vertical lines, Horizontal lines, and every other pixel:

There are three test patterns that are used to verify that the chosen output resolution is the native resolution of your display and that you are bypassing any internal processing in your display.

When the every other pixel test pattern is displayed correctly, close up you should be able to see a 1- pixel checkerboard and at proper viewing distance the image should appear as an even gray. If your display is CRT-based you will not see this checkerboard, but your screen should be an even gray.

When this test pattern is displayed incorrectly, the resulting image does not look like a fine checkerboard and may have irregular patterns. If this is the case then the chosen output resolution may not be the native resolution of your display or your display may scale all input signals even if the input resolution is already at native resolution. Check to make sure that the output resolution selected on the

AVLab TPG is the correct output resolution for your display.

Note: If this test pattern does not appear as it should and you have chosen the native resolution of your display, you may not be able to bypass the internal processing on your display.

The ‘Vertical Lines’ test pattern should appear as one pixel wide black and white columns. If you see any irregular pattern(s) in the image then you know that the display is scaling the signal horizontally.

If using a projector, the vertical lines will show distortion if any keystone is used. Keystone should be avoided at all costs – instead, hang the projector in the correct position.

DVDO AVLab TPG 23 A.04

DVDO AVLab TPG - 4K Test Pattern Generator

The ‘Horizontal Lines’ test pattern should appear as one pixel tall black and white rows. If you see any irregular pattern(s) in the image then you know that the display is scaling the signal vertically.

Judder (Frame Rate)

The Frame Rate Conversion test pattern consists of a vertical bar which moves slowly back and forth across the screen. The bar’s motion is updated once in each output frame period of the AVLab, and it moves a fixed number of pixels horizontally in each frame period. This moving bar test pattern is intended to identify the frame rates at which a display will operate. If the display is not performing any frame rate conversion, i.e., it is actually displaying the output frame rate of the AVLab – the motion will be very smooth. However, if the display is performing any type of frame rate conversion there will be very noticeable stutter introduced in the smooth motion. There may also be other objectionable artifacts introduced depending on how the display actually performs the conversion. These include tearing (top and bottom portion of the bar are horizontally misaligned) and distortion.

PLUGE patterns (2 white and 2 black)

These patterns are used to visually adjust brightness (black level) and contrast (white level) as well as to verify the display is in the correct color space mode.

RGB video is normally sent using all 256 bits (in 8 bit color) but YCbCr (component video) sets black at 16 and white at

238. This allows room above and below the active video for below black and above white. PLUGE patterns are specifically designed to allow quick visual setting of the black and white level.

DVDO AVLab TPG 24 A.04

DVDO AVLab TPG - 4K Test Pattern Generator

Using the black patterns (background is 16) so set the brightness level on the TV until you can just see the difference between 16 and 17. Depending on how fine the display adjustment is, you may not be able to get this exact, but 16 should be black and 17 grey. Everything below 16 should not be distinguishable.

Having this setting correct will bring out the details in dark pictures.

Using the white patterns (background is 238) set the contrast level on the TV until you can just see the difference between 237 and 238. Many LED and LCD TVs will not have enough contrast range to allow this to be set completely correct, and it is normally improper to set contrast to very high values. So it you cannot make everything above 238 clip (disappear) then set contrast to around 75% and double check using a dynamic range sweep with CMS software.

DVDO AVLab TPG 25 A.04

DVDO AVLab TPG - 4K Test Pattern Generator

Brightness & Contrast

This test pattern is composed of 4 quarter-screen blocks. Two of the blocks have a background level of standard black, and the other two blocks have a background level of standard white. Embedded in the black blocks are 3 bars. One is 4 IRE below black, one is 1 IRE above black, and the third is 2

IRE above black. Embedded in the white blocks are 3 bars.

The ‘Brightness/Contrast’ test pattern will assist you in setting up both the brightness (black level) and contrast (white level) of your display. The

‘Brightness/Contrast’ test pattern is composed of 4 quarter-screen blocks. Two of the blocks have a background level of standard black and the other two blocks have a background level of standard white. Embedded in the black blocks are 3 bars. One is 4 IRE below black (blacker-than-black), one is 1 IRE above black, and the third is 2 IRE above black.

Embedded in the white blocks are 3 bars. One is 1 IRE above white (whiter-then- white), one is 1 IRE below white, and the third is 2 IRE below white. The bottom two blocks differ slightly from these levels.

For the bottom two blocks, the blacker-than-black is at the lowest possible luma level and the whiterthan-white bar is at the highest possible luma level. When the brightness and contrast are adjusted correctly, you should be able to see the 1 IRE and 2 IRE above black bars on the black background and the 1 IRE and 2 IRE below white bars should be visible on the white background. When the brightness is adjusted correctly, black objects should appear ‘black’ with the details still intact and lighter areas should be ‘light’, not gray, with the details still intact. When the contrast is adjusted correctly, white objects will

DVDO AVLab TPG 26 A.04

DVDO AVLab TPG - 4K Test Pattern Generator appear ‘white’ with the details still intact. Because the contrast settings can affect brightness settings we recommend that you check the brightness setting after making this adjustment.

Also included in the pattern are 2 needle pulses, which can be used to check CRT voltage regulation as well as the presence of scan velocity modulation.

Note that the ISF PLUGE patterns are also an efficient way to set brightness and contrast.

Note: If you have a CRT based display, following the instructions above may yield a contrast setting too high. If the contrast is set too high, you will get blooming and loss of details in the highlighted areas.

It is more helpful to use the two vertical lines in the test pattern. Adjust the contrast up and down and you will notice that these lines will bend as you increase the contrast. To properly adjust contrast on a CRT based display, decrease the contrast until the vertical lines start to straighten out. If possible, the two lines should be straight. On some CRT, the lines may not straighten even if you turn the contrast to its minimum. If this is the case, slowly increase the contrast to a point just before the vertical lines have extreme bending. You have now properly set up the contrast of your display. Continue to set up brightness as detailed above.

Color Bars: (8 iRE75, 8 IRE 100, 8x3)

The ‘Color8 Bars75’, ‘Color8 Bars100’, and 8x3 will assist in setting up the saturation (color) and hue (tint) of your display. The ‘Color8 Bars75’ test pattern consists of 8 vertical bars across the screen at a 75% saturation level.

The ‘Color8 Bars100’ test pattern consists of 8 vertical bars across the screen at a 100% saturation level.

From left to right the bars are: grey, yellow, cyan, green, magenta, red, blue, and black. To properly adjust the saturation and hue you will need to either set your display to “blue only” mode or use a blue colored filter held in front of your eyes. You will also need to turn off any automatic flesh tone controls on your display before making these adjustments.

DVDO AVLab TPG 27 A.04

DVDO AVLab TPG - 4K Test Pattern Generator

A B B A

Adjust Chroma/Color/Saturation control so the outer bars (and small bar under it “A” ) blend into each other, then adjust Tint/Hue so that the inner bars “B” blend into each other. When the Saturation and Hue are adjusted correctly, the white bar and the blue bar should be exactly the same shade when looking through the blue filter. Saturation and hue settings interact with each other so after making this setting you may want to go back and check that the saturation setting is correct.

Grey Ramp

The ‘Gray Ramp’ can help verify that your display is showing the gradients between black and white correctly. You should see a smooth transition between black and white with this test pattern.

This test pattern is a horizontal gray ramp. There is a black level (0

IRE) vertical bar along the left of the pattern and a white level (100

IRE) vertical bar along the right side of the pattern. Between the two bars is a monotonic gray ramp which ranges from the minimum luminence level (i.e., blacker than black) at the left to the maximum luminence level (i.e., whiter than white) at the right. The minimum level of the ramp is a 10-bit digital value of 4 (equivalent to an 8-bit value of 1); the maximum level of the ramp is a 10-bit value of 1020

(equivalent to an 8-bit value of 254).

If AVLab is set to 8 bit color depth, and you are using YUV video, that means there are actually only 222

(238-16) luminance steps being sent to the display. The display then interpolates and smooths these steps to attempte to display something smooth across the screen. How much banding appears on the grey ramp gives an indication as to the video processing capabilities of your display. If the banding is

DVDO AVLab TPG 28 A.04

DVDO AVLab TPG - 4K Test Pattern Generator noticeable, then either using deep color (10 or 12 bits) assuming your source and content is compatible or adding a high quality video processor like the DVDO iScan Duo is an excellent solution.

** Note: Grey ramp is only available if the output is set to YC

Solid colors

These patterns are normally used with a color meter and software to read specific color levels. IRE stands for International Radio Engineers and it is a relative scale, NOT an absolute. It defines the volt peak to peak video divided up into 140 IRE units. This is done to make numbers for luminance levels easier to communicate. In the ISF Training Manual, it is described as the amplitude of the video signal from blanking (zero volts) to peak white is 0.714286 volts or 100 IRE units. Synchronization signals extend from blanking to -0.285714 volts or -40 IRE units.

Dynamic Patterns

These patterns are generated by a connected computer, normally a calibration software package like

CalMAN or Chromapure. A custom USB/Serial command is used to precisely define the color as well as the size of the window.

Note that the serial command (AF) accepts input in RGB only and the output is set by the output settings on the

AVLab OSD (or serially controlled).

If the output setting is currently RGB, then a triplet of

16, 16, 16 (limited range black) would be sent to AVLab as 0, 0, 0 (0% for each) and be output as 16, 16, 16 in the center. If the output setting is YC, then the output

DVDO AVLab TPG 29 A.04

DVDO AVLab TPG - 4K Test Pattern Generator

F/W

01.01 will be 16, 128, 128 (limited range black YCbCr).

The window size is given in %. For more details see the serial control spec and examples in Appendix A.

For Firmware version 01.01 and later, the new full triplet command is implemented allowing software to send the exact 0-255 RGB value to AVLab for more precision. This command is detailed in Appendix A with examples. To make the color more precise, all controls that could affect the outcome are included in this single command which overrides all output settings from the On-Screen-Display or previously set via serial commands. This includes:

• Input range (That 0-255 triplet of 16, 16, 16 – did you give it to AVLab as limited range where you mean black or did you provide full range and meant grey)

• Output Color space – output the color in RGB, YC 444, YC 422 (except in 4K/60 where is it 4:2:0)

• Output range – limited or full – note that this affects both the numeric value as well as the info frame that the TV uses to interpret the value

• Window size – given in % from 0-100 (although a 0% window is non existent)

• Window background color – given as an absolute decimal number from 0-255. Normally this is just set as black (0 for full range, 16 for limited range), but if the software is asked to provide a constant

APL (Average power level – meaning the background changes to balance the overall brightness of the color and window size in the main window so that Plasma TVs do not try to auto adjust overall screen brightness) it can be provided to AVLab.

XHatch (coarse, fine, and focus):

To get the best picture from your CRT-based display or projector, you will want to make sure that the red, blue and green signals are converged properly. To assist in converging these three signals we have included two test patterns. In addition to convergence, you will also want to make sure that the focus is optimally adjusted. We have included one test pattern designed specifically for this application. On some displays, these settings, may not be available unless you get into the service menu. We recommend that you hire an ISF-certified technician to make these adjustments if you do not feel comfortable getting into the service menu.

A Typical Calibration Session:

Display calibration is a process that requires some level of expertise. Companies like AVPro Alliance offer

Imaging Science Foundation [ISF] certification classes using CalMAN, and LionAV offers THX calibration classes using ChromaPure; both run over a few days to train an installer in the art and science of calibration. While there are some excellent tools that help automate the process, a thorough understanding of the relative level of importance of each adjustment and some means to objectively measure the result with a calibrated meter are required to achieve an optimum result. Nevertheless, many adjustments can also be made by eye by using a specially designed pattern. To this end, AVLab TPG has both visual patterns for quick adjustments as well as computer controlled patterns for use with software control.

**Note that this is only an overview of the process – more detail can be found in a great overview by

**Kal at CurtPalme.com also has an excellent step by step process using the ChromaPure system that can be found here : Chromapure software can be found on the included USB flash drive.

**What Color Calibration Software to use? While there are a number of choices, there are three that stand out: CalMAN by Spectracal (trial version on disk), ChromaPure (trial version on disk), and HCFR – a free/open source package that can be found here .

A typical calibration normally involves the following steps but many other checks and adjustments can also be performed. This example process is based on the ISF workflow using CalMAN 5.3 software.

1) Before you start: a. Checking equipment capability and the room: Contrast ratios interframe vs intraframe – Using the large checkerboard, verify that target contrast ratios can be achieved given the room conditions. 150:1 is always a good intraframe target. b. Setting up a PC (Media center or Gaming) – set up component 16-238 super white, RGB or component, 4:2:0, aspect ratio, and output format, c. Playstation setup tips – cnet.com.

DVDO AVLab TPG - 4K Test Pattern Generator d. Be sure to wear appropriate attire – no white – even stripes, no laptop pointing at screen e. Regarding projectors, most of the time the lamp is not a pure white but tends to put out more blue and green than red or vice versa. In this case, to calibrate requires cutting colors as opposed to boosting them so overall light comes down. So it depends on the usage model whether this is better for the customer or not. A projector in a school showing only powerpoint might be better served uncalibrated so you get more light output for the money. f. About meters. Basic calibration can be done with just about any meter, but some are better in accuracy than others. Some midrange meters have pre-programmed memories that let you choose the sink type (LCD, LED, projector front with HPD lamp etc) – these settings can make a middle level meter work much better by ignoring some colors that are not in the color space of the device being measured. Spectral devices (like I1pro2 and Minolta) are slower and the ipro is good at lighter areas but poor on dark areas. To get the speed of a tri-stimulus device, you can take a profile reading using the ipro and then apply that offset to a tri-stimulus like the Klein or X-Rite C6 meter. C6 uses gel filters and can go out of calibration after a period of time so recalibrate the meter periodically. However, it can only be calibrated as long as the filters are still within a reasonable range. The Ipro has no filter and is accurate long term.

2) Calibration Setup a. We recommend the ISF calibration workflow b. Adjust frame and geometry and make sure that overscan settings are not on by default; make sure that the single pixel line around the edge is visible. c. Insure that the proper video setting is being used on the TV – it should be set to Video or YUV.

Unless you have a source that only puts out RGB, its best to have the entire system send the display YUV and let the TV convert to RGB for display. d. Properly set up the test pattern generator – it needs to match the source. For instance, the

TPG should not be allowed, in normal calibration, to automatically match the TV capability.

Check the main source – blueray to other - and set TPG to that bit depth and calibrate to that. e. Choose the correct meter/combination for the job. A high end calibration begins with calibrating a spectral meter (ipro, Minolta or other) to a tri-stimulus device (Klein, C6) to get the most accuracy and also the speed of the tri-stimulus. f. Calman setup – under settings grayscale points – if using a tri-stimulus start with 10 point 10-

100, if i1pro start at 20% as it does not measure dark quickly. Gamma setup of 2.35 is optimal target

DVDO AVLab TPG 34 A.04

DVDO AVLab TPG - 4K Test Pattern Generator g. Position the meter properly – dark room, proper distance and view h. Pay attention to redundant controls – processors, PCs and displays and DVD players all have controls. – Start with TV. Work from the light – calibrate the TV using generator right into TV, then put generator into AVR and recheck, then back to source.

3) Calibration (This below is based on the ISF workflow in CalMAN but the general flow is applicable in any software package) a. Pre-Calibration – First step is always to take a baseline, both for comparison/baseline, and as a way to show the customer the before/after as part of the calibration report. This screen is relatively automatic and only requires a single button press with no TV adjustments. b. Mode settings – Check each TV mode (Cinema, Theater, Movie, Custom – avoid names like vivid or dynamic) in this screen looking for a mode that can be adjusted and is closest to proper CCT (color temperature) and gamma. c. White point and Color space: Run the series and adjust the TV “Color temp” for the one that lands the white closest to the center white target. Also adjust the color space on the TV for the one that lands the primary colors closest to the targets – preferably outside the targets as opposed to inside. d. Turn off all automatic features – auto iris, auto brightness, black expansion, auto flesh tone etc. e. Adjust luminance – Run the series and adjust the TV backlight to the correct light output for the environment, normally 40 fL for dark rooms and 60fL or more for bright rooms. i. Note that backlight setting should not affect brightness and contrast settings, but sometimes it does, so you should check this before and after brightness and contrast ii. On an LCD, backlight or panel brightness should be an independent setting. On a projector, use the iris setting (high lamp or low lamp also if available). Be sure to turn off auto iris for initial calibration, then turn back on at the end to make blacks darker.

On some plasmas, this is labeled “Cell light”. f. Adjust dynamic range: i. Start with a black PLUGE pattern and adjust brightness such so that you can just see the

17 block (16 should be black – same as background and don’t see any blocks under 16) ii. Move to White PLUGE and adjust contrast until you can just see the 238 block and everything above is clipped and same as background. Some TVs cannot be adjusted to

DVDO AVLab TPG 35 A.04

DVDO AVLab TPG - 4K Test Pattern Generator clip at the top end and 100% contrast is rarely the right choice, so if it does not clip start with something around 80% to begin adjustments iii. Double check the visual adjustments with a meter read dynamic range series iv. Note that the brightness control actually controls the detail in darker parts of the image.

If missing information in the blacks, brightness is too low. If missing information in the white part of the image, the contrast is too high. Higher contrast washes out the detail in bright images. g. Gamma – the nonlinear luminance adjustment: Run the series and check each of the TVs gamma settings to find the one closest to the 2.35 target. Some devices have a 10 point gamma adjustment that allows precise adjustment of gamma if it is non linear. h. Set overall color: Using an 8x3 color bar and either a blue only mode on the TV/Projector, or if not available a blue gel/glasses to block out all other colors. Adjust the color and tint setting until the blue and white bars next to each other appear to be the same. i. Resolution and Bit accuracy: Use sharpness pattern (Freq Sweep) to adjust sharpness until the finest detail is visible (fine vertical lines) but no white bleed is visible around the center box.

Use the Frame/Geometry pattern to verify that overscan and other scaling on the TV and any inline AVR/processor is off. With the frequency sweep pattern, verify that no keystone is used

– keystone will distort the fine vertical lines. j. Grayscale Two point adjust: First pass, use 30 and 80% IRE to roughly set overall white balance –normally using only the gain and offset controls for each color. You should attempt to find a setting with the lowest delta-E across the IRE range, preferably under 3 with as little green error as possible. As green is the most visible, the green error should always be the primary target. Adjust red and blue first and attempt to pull green into proper alignment without actually adjusting green. Also, use the smallest window pattern size possible for TVs that dynamically adjust light output. k. Grayscale multipoint and gamma: If available use 10 point gamma and white balance controls to perform final adjustments across the entire luminance range. Again, leave green with zero error. l. Color Management System: i. Goal is to get every parameter correct for every color. CMS controls, not present on every display (and if not a DVDO Duo adds that capability to any display) normally provide saturation, hue, and luminance for each specific color to properly position that

DVDO AVLab TPG 36 A.04

DVDO AVLab TPG - 4K Test Pattern Generator color on the reference color chart. For primary colors (R, G, B), start with luminance, then adjust the color with saturation and hue (or x, y) and then readjust luminance. For secondary colors (C, M, Y), focus primarily on hue and saturation. m. Recheck everything – since many of the controls are interactive, the goal is to find the best balance between all the settings. You should be able to go through the entire workflow without making any further changes. Once this is done, a post-calibration report should be run to provide to the end customer.

4) Double check the source and any other components in between like the AVR or a video processor a. Need to understand the best place to: up-convert to 4K, convert to RGB, may need to set brightness or contrast here. Oppo is a good example where you use a test pattern generator – adjust the TV correctly, then come back and adjust the source as necessary to make it all match.

Troubleshooting:

Issue:

No picture or TV reports signal not supported

Garbled picture

Possible Resolution:

TPG is putting out a resolution or bit depth that the TV cannot handle.

Press the button on the side of the TPG marked “resolution” until auto appears and a signal returns.

The TV is incompatible with the TPG output settings. This is most commonly a color depth set too high for the resolution that the TV supports. Press the resolution button on the TPG until auto appears and then reduce the color depth before raising the resolution again to test.
