I'm having an issue with a monitor I recently purchased. It's an Acer B247W 24" 1920x1200 monitor and I have it hooked up to my laptop via HDMI, which is an Acer Nitro 5 (AN515-51).
Using the below video as a test, I get bad screen tearing on the monitor, but only under certain circumstances.

When I mirror my laptop's screen with the monitor I don't get any screen tearing or judder on either of them. But when I have it set to use the external monitor only with my laptop's screen turned off, I get screen tearing, and it's not consistent either. Sometimes it'll be on the black square, sometimes it'll be on the white square, sometimes it will be on the newspaper background. Basically it's just kinda random.
When I first got it and set it up there was bad stutter as well. After updating my Nvidia GPU driver the stutter seemed to go away but I still have screen tearing. I've reinstalled both the Nvidia and Intel display drivers and I've updated Windows 10, yet the issue still persists. I've tested the monitor with my Steam Deck as well and I don't get any tearing regardless of which screen configuration I use, but then again I know the Steam Deck has some pretty sophisticated anti-tearing tech so maybe it's not the best device for me to cross-reference with in this situation.
The only other thing I could think of doing is getting a DisplayPort cable and seeing if that helps. I've already tried a few HDMI cables and none of them have made a difference. The monitor has Adaptive Sync but it won't let me turn it on unless it's connected via DisplayPort. If anyone has other suggestions I'd really appreciate them.
