It would be great if eventually we could compile a 'dither-free' database similar to the tftcentral flicker-free db.
One thing I was thinking - would it be worth testing a single card in different states e.g. During POST/BIOS menu, Win OS Desktop, Linux OS Desktop just for further comparison to see if there is dithering on these cards constantly or when loading specific software.
Also this could also be used on games consoles etc anything that uses HDMI, correct? E.g. a good xbone and a updated (bad) xbone? A good DVD/media player and a bad DVD/media player. The link may not just stretch between PC's but other devices.
