NVM. I believe this fixed it ""Ashita.exe", select "Properties". Under the compatibility tab, check the "Override high DPI scaling behavior." box and set "Scaling performed by: " to "Application"."

Were you able to play 4k before? If so then something could have changed with a video driver update, if not then you may need to check to make sure your video card supports 4k or 4k upscaling, and it's a weird little thing but if your video card does support 4k you may need to make sure your hdmi cable can transfer 4k, and ofc you're going to need a 4k monitor to enjoy full 4k.

good luck

Yes i have a card that supports 4k, and monitor. I believe I have the problem fixed now. Thanks

I was going mad trying to figure this exact problem out. Thank you kindly, its a whole lot better experience for me now. Played retail for the last year on and off in 4k and it was nice, so so so happy to have figured it out thanks to you.
