Have a problem that kind of makes no sense to me. I swapped from an RTX 4090 Suprim to 5090 FE and now the monitor randomly turns off for 1-2 sec and recovers. Tried 3 different cables (Silkland DP 2.0 and IVANKY) also the default cable. All of these cables worked fine before. I am using the latest firmware.
The monitor wasn't even used at all after I sold the 4090. I just plugged it in after a month. When using GSYNC, this blackscreen never happens. When you turn off GSYNC (aka adaptive-sync on the monitor's settings), you lose connection to the monitor for 1-2 sec whenever it feels like it. Could be 1 minute, 15 minute or 30 minutes. This happens on desktop and in games. Monitor goes black and in the top left you can see the Display Port icon, as if I manually reconnected. Stock 5090 settings. You don't need to use GSYNC in NVIDIA Panel, you just need to have Adaptive-Sync enabled on the monitor (in case you don't want to use GSYNC but want to fix the issue)
I never had these black issues before with adaptive-sync off. Windows is fresh, DDU drivers multiple times, tried the last 4 drivers and it still happens on 572.83. I also tried the 1080p 240Hz BENQ that I have here and it didn't cause any blackscreens (didn't test it much tho) but I am guessing this is a driver issue with DSC and for some reason "Adative-Sync" set to enabled on the monitor the issue go away.
So what do I do now? RMA the monitor or is the GPU broken? It's hard to tell what's happening here. The GPU works fine under any stability test (3DMark etc) with max OC, heavy undervolt and also stock. Tried all ports (except HDMI since I don't have an HDMI cable atm but will soon)
Waiting on a SILKLAND 2.1 DP cable to try that. Edit: didn't do anything (not that I was expecting it to, wanted the cable anyway)
What a frustrating issue. Specs below
CPU: 9800X3D
GPU: RTX 5090 Founders Edition
Motherboard: X870E Nova (3.15 BIOS) and using PCIe x16 5.0 (tried 4.0, still the same thing)
