Gaming in 1080p on a 4k monitor will look blurred ass just like playing 720x450 on 1440x900 etc. Because no matter what, the GpU driver will cause interpolation if you scale the image using GpU. And if you leave the scaling to monitor, it will still blur the image.
What happens if you play 1080p on a 4K monitor?
Running 1080p on a 4K display ends up being one fourth the native resolution. If your graphics card drivers support integer scaling, you can double the width and height and get a "sharper" picture.Can you play 1080p on 4K?

Unfortunately 1440p is only 76% bigger than 1080p, so the scaler won't be able to precisely transpose the 1080p image onto the 1440p screen. That means there's a bigger risk of blur and other visual artifacts that make the picture look substantially worse.Is a 4K monitor worth it for gaming?
4K is an extremely taxing resolution to play games at, even in older AAA games and while you may be able to get reasonable frame rates with mid-tier graphics cards, the best graphics cards for 4K gaming are at the top end of the pile.Is 1080p good for PS5?

Greater Visual DefinitionSmaller details are more visible in games displayed at 4K because they contain quadruple the amount of pixels as 1080p resolution. The image appears twice as sharp but in order to experience games in Ultra HD you need a 4K monitor that is ideally 27” or above, such as the Asus Rog Swift.
