what is this non sense, HDMI 2.0 can do high refresh rates and res
its you only option if you have to do long cable runs
i have 1440p at 144Hz over a 15m HDMI cable (i had to try several cables in the end unamplified couldnt do it, the best i got was 100hz at 1440, so i had to bite the bullet and get and amplified cable that was twice the price of a no name chinese cable)
