I got a new ultra wide Samsung odyssey G8 OLED 34 inches, it provides 3440x1440 @ 175Hz with HDR. It worked for about 2 days just fine, VRR, HDR was working flawlessly out of the box with MacBook Pro 16" M1 Pro chip (running Ventura 13.0). I turned it off, and came back 4 hours later, and the monitor is not being recognised correctly (it is now recognised as a 14" display)!!! Im using display port to thunderbolt to connect the display, and I've tested it with the second monitor (16:9 aspect ratio @ 240Hz) it works fine... but the ultrawide monitor is not... any help? I tried SwitchResX to setup the resolution, installed Ventura 13.2 beta for it, but even SwitchResX is not fixing the issue)

Hi hbatax.
Sorry you're having trouble here! Since these forums are for developer support, you're more likely to get help with this issue via Feedback Assistant (an app that comes pre-installed on macOS). Feedback Assistant will also upload some system diagnosis files that will help the display teams resolve your issue, so please go that route.
