Windows 10: Unable to change the Display Resolution/Aspect Ratio on 2nd monitor.

I don't understand why my second monitor left looks like this? it says the display resolution is 640x480 but should be and WAS 1680x1050. It somehow just... changed.. and I've tried doing the same 5 things that every single link on google suggests - update driver. select a specific driver. uninstall driver. open device manager. use the command prompt. NONE OF THEM WORK. as you can clearly see the display resolution option is not allowing me to select any options its greyed out. selecting Display Adapter Properties in the Advanced Display page where it "Lists All Modes" only allows 640x480

Change monitor aspect ratio

The aspect ratio of your monitor is fixed and can't be changed, because it depends on the arrangement of the pixels on the screen.

When you display an image on your monitor whose aspect ratio is different from the aspect ratio of your monitor, what you'll see depends on how different the aspect ratios are. Usually, you see black bars on the top and the bottom of the screen, or on the
left and the right, a familiar appearance known as 'letterboxing.'

How do I change the aspect ratio of my monitor?

I have been trying to change the aspect ratio of my monitor from its default 4:3 to 16:9.
The aspect ratio was fine until the VGA outlet in my PC stopped working, and moving it to the other VGA outlet seems to have reset the aspect ratio to 4:3.

Display Settings only lets me select a resolution of 800x600, 1024x768, or 1280x1024, all of which are 4:3. I have been Googling 'how to change aspect ratio', but all of the solution I am finding are telling me to go to 'advanced display options'—which
doesn't seem to exist.

I have also tried to change the resolution with the options of my monitor itself, but the only aspect ratio options are 'stretch to fit' or 'stretch to fill'.
