A huge problem for me, the only displayport 2.1a cable I’ve found that works for my RTX 5090 + 240hz uncompressed HDR 4K monitor came with the monitor. It’s amazing that it’s pushing around 80gbps through that wire and it’s an incredible visual experience.
Gods, this is giving me flashbacks. I had to find a usb-c to display port 1.4a cable for my Gsync Ultimate screen with 240hz. I tried out I think 10 different cables, before I found one that actually worked....
