Im using a laptop with a second monitor but bucause my laptop only has one hdmi output in using a usb a to hdmi adapter it worked fine for 5 moths but after a Windows update is stopped working. I found put that it is working in 1680 X 1050 but my monitor is 1920 x1080. If i change the resolution to 1920 x 1080 it wil dat no signal but in 1680 x 1050 or lower it does work. have tryed everything that i could find but nothing worked like updating my drivers. I even uninstaled that Windows update but stil didnt work. Now i did reset my whole pc and stil not does not work in the right resolution. Does anyone now how to fix this let me know Please.

Did you try using a "known good" (and different) hdmi cable of correct rating?

Yes a bad update could disturb things. But you said you reset everything so maybe that wasn't the problem.

Heat could be though. Make sure your pc fan works. I'm unsure but I think "power saving" and "thermal limiting" can effect graphics modes available in 2021.

May I ask what GPU your laptop has? AMD/NVIDIA/intel?

First update to the latest driver package from Nvidia. Then open Nvidia control panel in the change resolution tab under "Display" see what option it gives you.
i did download the lasr driver package but i dont see the display tab
i only see: adjust image setrtings with preview, manage 3D settings and set physX config
