My screen resolution is currently 1024 x 768, but needs to be 2048 x 1536. It will not change when I go to settings, I merely get a message that says "Input not Support". When I tried the help online, it said I need to update the graphics driver, but two attempts to do so haven't resulted in any success. Any ideas?
You are most likely using legacy GPU, so you need to install legacy drivers or your GPU is not supported in 10.
How do I know what type of GPU I have? Incidentally, the problem started suddenly, and yesterday reverted back to the correct resolution. Any ideas what happened? I don't recall actually being able to do anything to solve the problem. I would like to be prepared if it happens again.
Probably Windows has downloaded the driver for you.
You can use some of those to see, what GPU you have.
GPU-Z Video card GPU Information Utility
HWiNFO - Hardware Information, Analysis and Monitoring Tools
Here's a fast and convenient way to check for GPU: Start > Windows System > open Device Manager. Click on the pointer at left of Display adapters. That should show your GPU. Right click on the GPU name and select Properties. Info on the Driver tab will show driver version and date. Update the driver if needed.
