How does the Splitter 4K UHD combines EDID from 2 sink devices?
The combinator checks video and audio capabilities including DVI or HDMI capability and distributes information so that each display will both show video and audio. So it has to take into account that it cannot send 7.1 to a stereo receiver or 1080p to a 480p display. So it configures EDID based on the best shared capabilities. However, if one the displays is DVI and the other one is HDMI then it will still send audio to the HDMI capable display while keeping the other output as pure DVI. So you will still hear audio. Splitter 4K UHD also have a windows EDID utility to manually upload, read ,write, save or load any EDID file.
What does the 4K Enhancement mode?
The 4K enhancement can be hard to spot on 50inch or smaller screen. What happens inside the core is that when 1080p24 gets scaled to 4k24 it means pixels are actually doubled horizontally and lines are doubled vertically. Our 4K enhancement mode offers a different ways to deal with duplication of pixels and that's what the mode button effects. It means it can blur neighboring pixels a bit or sharpen the pixels.
If you have a small UHDTV then you can take a magnifying class and look at the edges of text. When you press the button there is a change noticeable on the text but the overall picture doesn't appear to change much unless you have a bigger 4k TV then its more noticeable. On 80inch UHDTV the 4K mode enhancement benefit is much easier to spot.
