U2713HM, Radeon RX 580, Apple Mac Pro, issues
Just installed a Sapphire Radeon RX 580 into a 2010 Apple Mac Pro. Using a 5m long DisplayPort cable and going straight to a U2713HM. High contrast text is showing pretty severe chromatic aberration. It's like the RGB channels are misaligned. I've reseated cables, factory reseted the screen. Nothing helps. What could be the issue?

@MetrMusic 5 meters is pretty long. Have you tried using another more typical length cable (say 2m) and/or connecting the display to a different source device? When you have an issue like this, you need to start isolating variables by swapping one component in the overall setup at a time to narrow down the cause of the problem.

I've tried it with 2 different short cables now.
HDMI cable, no shift in RGB but won't allow higher resolution.
Short DP cable displays same shift in RGB as the long one.
Both DP cables are 1.2. Should I buy a 1.4?
