Hi,
I've got my PC connected via an HDMI 2.0 cable to my Samsung Q95A TV (the PC is also connected to a 1440p monitor. This has been working fine for about a year.
I recently upgraded my GPU from an NVIDIA GeForce 1080 TI to a 4080. This new setup worked for maybe a week before the problems started. First, I was unable to enable HDR, but Game Mode was working. A day or so later, Game Mode also stopped working. I can't enable input signal plus either. Doing any of these things causes the TV to immediately lose signal to the PC. This is at 4K/60hz.
I tried playing around with resolution settings, using a different 2.0 cable, etc., but nothing works. I can still watch TV on my PC as long as I don't put it into Game Mode or enable input signal plus. I am waiting for a 48gbps cable to see if that maybe solves the problem, but I've seen a lot of threads about this kind of issue with the 3000-series cards and absolutely nothing that indicates Samsung has solved it.
I tried contracting Samsung support, unfortunately the chat was unhelpful and they are unable to provide remote assistance in a language I speak very well.
Has anyone managed to fix this with a 3000 or 4000-series NVIDIA GPU? Is my TV now just an expensive brick?
