Problem: Low Resolution 800x600

I installed Zorin OS 15.2 Education. This is running alongside Windows 10 (no problems in Windows).

My screen resolution is stuck at 800x600.
I tried uninstalling and reinstalling the NVIDIA drivers and it didn't do anything.

Here is the output for "xrandr" and "sudo lshw -c video | grep 'configuration'":

Is there a known solution?

Check the output with

Code:

xrandr

It may be VGA1, HDMI and so forth. Identify which one you are using, that is your connection type.
Open a terminal and put in

Code:

xrandr --addmode <your connection type> 1200x1000_60.00

where <your connection type> is what you found above, VGA or HDMI... and next is resolution followed by the refresh rate.
Set resolution as needed and see if that works; please update thread after testing.

What I've found in Live mode or as a VM before install get same res but going to Settings | Devices | Display then clicking to the right of the low resolution offered then brings up higher resolutions - you have to scroll upwards for higher res - or do you get nothing at all?
