Does it make any difference (quality-wise and input-delay-wise) if I use a DisplayPort to HDMI cable directly or a DisplayPort to HDMI adapter, followed by a regular HDMI cable?

    I just know I couldn’t use any of those to get 4k. I needed to get a cheap ATI Radeon card with direct HDMI output and a high quality HDMI to HDMI cable to get 4k. I had to make sure both support 4k. The card and the display will do a very short test of the cable on each connection and if it doesn’t carry enough bandwidth and fails, the card will tell the OS and 4k won’t even show up for selection.
