Just because Windows indicates that the driver is correct is not necessarily so but that’s another game so assume for now that it is correct and hope it’s just a screen resolution problem
Right click on the desktop and select “Display Settings”
You will see “Scale and layout”
The size of text is probably set to “100 Recommended”
The resolution should be set whatever is the “Recommended” for your system (mine is “1680 X 1050 Recommended”) this is where you can adjust the resolution to get a better display, by adjusting the resolution (in your case) upwards
Start by incrementally selecting a slightly higher resolution until you have a satisfactory display unless you see a “recommended” display available and select it, see how you get on.
Orientation should be set to “Landscape”
Some usual resolutions are
19-inch screen 1280 x 1024 pixels
20-inch screen 1600 x 1200 pixels
22-inch screen (widescreen) 1680 x 1050 pixels
24-inch screen (widescreen) 1900 x 1200 pixels
