I bought a new laptop with UHD display (3840 x 2160), but it does not seem to work very well with SW. SW becomes really slow and difficult to operate with.

I have tried to change the PC resolution, SW compatibility settings, but none of them work.

Could anyone give me any advice about how to fix this problem? The SW I am using is 2017-2018 student edition.

By the way, the background of my SW is always gray, does this have to do with anything about this problem?

Thanks!
