Hey Guys, I really hope someone can help. I've been trying to get this issue fixed for a while.
I have taken ownership of a Gigabyte CV27F monitor. I iniitially just plugged it in via DP and my older monitor left on HDMI. Booted up computer, nothing on screens. Wait for a few minutes, press power button and nothing changes (indicating incorrect booting possibly, I had to do a hard shut down by holding power button). I tried again with new DP ports (on monitor and PC), exactly the same issue. I then removed the DP, booted with just one monitor, windows loaded, plugged in DP (not ideal I know) and the monitor came on and I was able to use it and it all seemed normal. I have booted up with the monitor in HDMI and it works perfectly. Also just to say the monitors know they are plugged in as when I remove a cable when in the "booting" the monitor that had the cable removed then says "no input". The PC and monitors will also go to sleep and wake up in DP but will not boot from "cold" . Also when it doesn't "boot" when I eventually get it to boot over HDMI, when windows loads it looks like it is doing a validation check (black screen with windows loading circle for a minute or so) then loads to windows log in page and takes longer to boot than normal. After this though it acts normal as long as I don't attempt a boot with DP plugged into the monitor.
I then started doing some research. Found out it could potentially be a crap cable (even though it was supplied with the monitor) so I bought a new one, tried that and still the same issue.
I have been speaking to the manufacturer of the cable to see if they know what the issue could be. They have tried to say it's an issue with potential short on ports of the GPU (when he found out I had tried 2 ports on the monitor and 3 ports on PC he took it back) . The GPU is a AMD RX 5700 and is 7 months old. I have had no issues at all previously so I doubt it will be this. They suggested it is either the DP processing on the monitor side or the PC side in the GPU.
I'm really stumped. I'm going to struggle to be able to test the monitor on other PC's with DP connections as most of my friends and people I know with PC's have HDMI or mini-dp and also I don't have any other monitors to try on DP so I am a little bit stumped and struggling to diagnose this issue. From the descriptions of the Pin 20 issue from cheap cables in the past it sounds exactly the same or similar at least (although the cable manufacturer advised male to male DP specs say pin 20 should not be used and their cables 100% do not use it). I'm almost at the point where I might just settle and use the HDMI for the new monitor and convert the HDMI on the other monitor to DP and see if that works. If I do this I lose HDR and 165 hz as can only do 144hz on HDMI so would prefer to get it working.
Any advice or help anyone can give would be awesome.
