Windows 10: Why has my second screen gone blurry?

My second screen has suddenly gone blurry. I am using Windows 11. It was fine this morning, I went away, came back and is now clurry.

Applications on main and second screen blurry

Hi,

I have a second screen hooked up to my laptop and some applications are blurry on my main screen (laptop) but not on the second screen. I have the same problem the other way around, some applications will be cristal clear on my second screen but not on my
main screen. Probably has to do something with DPI scaling and font sizing. I've already tried the following solutions.

• Change scale in display settings (It won't detect the second screen even though it is working).
• Updated both my GPU's (GTX 1050 and a Intel stock GPU).
• Tried to change the DPI settings on specific applications.
• Downloaden XPExplorer (set it to Windows 8 DPI scaling)

None of them fixed my problem. Is there any way to fix this?

 

Surface Pro 4 - Scaling (Blurry) Issues With Second Screen

I have a Surface Pro 2017 i5, 2 docks (home and work) each with 2 1920 screens. The second 2 screens were blurry particularly when running office - scaling is fine (200% on Surface screen and 100% on the 1920s). Different programs handle scaling differently
- Office has blurring problems but no scaling problems, Edge is good with both. All makes diagnosing more difficult!

The fix for me was changing the primary monitor to one of the 1920s and then restarting (or logging out and in). It seems that if the Surface screen is primary then it scales from this and ends up blurry, whereas scaling from the 1920s to the Surface screen
is an easier step.

The neat thing about this is when you are not in dock the Surface screen is then automatically primary and sorts itself out.

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.
