DVDO iScan Mini - 4K Scaler / Video Enhancement

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.

XHatch (coarse, fine, and focus):

Use this pattern to help adjust the lens on your front projector. 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.
