Windows 10: My whole screen is blurred and everything is big?

When I started my computer yesterday as usual, I immediately noticed how everything is warped and blurred. (see picture) This is of course anything but normal. My writing is pixelated and even in the login window everything is strange and warped. Google and games such as Minecraft are pixelated, large and fill the whole screen. Slowly I am really desperate, because there are no solutions on the internet

Can not access computer. Blurred Sign in screen.

- that's what you're referring to, I believe- the background to the login screen, rather than the lock screen- but should not affect the ability to log on.

That said, if tahalodhi16 is having trouble logging on, but not otherwise, it's worth trying what you suggest.
The article I've quoted also gives the registry details, so that could be done in Safe Mode if it's easy to access that in this situation.

Clarification is needed else we are simply guessing.
