Hello!
Reporting that I have a possibly related issue with Lenovo P15 (Quadro T2000) and Samsung Odyssey G7 as external via HDMI on laptop itself (not docked). Just a single external screen, running extended desktop with external and internal display.
I have not ran into display corruption - at least yet - but connecting to the display is really hit and miss.
I have to unplug the hdmi from laptop, then keep the monitor “active” by going into OSD → source, replug HDMI to get a signal.
Resolution or display scaling changes usually result in lost signal too. Refresh rate changes don’t seem to cause issues though.
Issue happens regardless of 24-bit or 30-bit color mode.
For reference the display works flawlessly with my home desktop PC (DisplayPort) and it worked flawlessly with my older work laptop via HDMI too.
Display has newest 1011.0 firmware.
Using NVIDIA driver ver. 471.41 in Windows 10 x64 Enterprise 19042.1526
