KD-65XE8596 Black Flickering screen with long HDMI Cable on 4K HDR

My TV works fine in 4K HDR when I use a short 1.5-Metre cable(the one that came with the PS4 Pro) but when I use a 10-Metre HDMI which I bought in my local Sony Centre for a hefty price it flickers black constantly and often just loses input entirely.

If I set my PC to ycbcr 4:2:0 and turn off HDR in Windows, it runs fine but I need HDR obviously so this just wont do.

Hi @indeed90 You should return your “hefty priced” cable for a full refund. It has absolutely nothing to do with your TV or Sony. The recommended maximum length for 4K HDR is just 3m. 5m is a stretch, 10m no chance. You need something like a fibre optic HDMI cable for 10m.
