GPU scaling is a feature available to many AMD graphics cards that will essentially scale the image so that it fits the screen both vertically and horizontally. Furthermore, GPU scaling helps if your mother doesn’t support a specific resolution.
What do you do when there’s a video or game looking very blurred and stretched? Monitor scaling is probably the reason and to get rid of the issue, you will have to enable GPU scaling on your AMD settings, which allows you play older games which require an aspect ratio such as 4:3 or 5:4.
How to Enable GPU Scaling
In order to enable GPU scaling on your system equipped with AMD Crimson (or later) software and a compatible AMD graphics card, follow these steps:
Open your AMD Radeon settings
Click on Display at the top
Find GPU Scaling on there and enable it
Types of GPU Scaling
There is also a setting called Scaling Mode, which you can use to decide how the image should be scaled.
Maintain Aspect Ratio will, just like it says, maintain the aspect ratio and add black bars at the top and bottom, or at the left and right of your display
Scale Image to Full Panel Size will stretch the image so that it fills the screen entirely. The image might look weird as a result of this because it’s scaled from a different aspect ratio
Use Centered Timings will center the image on the screen and put black bars around it. This is useful if the image is smaller than the screen’s resolution.
We recommend that you pick the first option. It might also be shown as “Preserve Aspect Ratio”.
Effect on Input Lag
GPU scaling will add a bit more input lag because of the added processing. This is usually just fractions of a second, which is unnoticeable in videos, but it might be noticeable when playing games. Gaming monitors used for competitive gaming should have the lowest input lag possible.Therefore, you must decide if GPU scaling is worth it in this regard.
