Phoenix 1.0 When video source is HDMI and the screens are daisy chained using DVI, screen 1's color looks different to the rest
HDMI support both YCbCr and RGB color space while DVI support only RGB color space.
When the source is HDMI and the video signal is then looped thorough using DVI daisy chain, if the video signal is sent using YCbCr color space via HDMI, this will automatically be translated to RGB to the 2nd screen onwards, and as a result there will be difference in the interpretation of picture as the color space doesn't match 100%.
One way to avoid this is to ensure the video signal from the 1st screen is RGB.
Another method is to set Picture->HDMI Input Range to Full (especially the first screen)
The following is the test from Philips lab in Europe
Showing the result when the 1st screen receive video signal in RGB (Picture->HDMI Input Range =Full allow it to support RGB color space, whereas Auto seem to limit it to only YCbCr color space only)
