What is GPU scaling? Types and how to enable scaling?

If you are one of those lucky 80s or 90’s kids who had an opportunity to play iconic games like Contra or Mario, you know how addictive they can get. Even though they don’t provide you with top of the line graphics, these games have remained a favourite.

If you are one of those people who love to play these low graphic games, you might be familiar with GPU scaling. All these older games come in a different aspect ratio of 4:3. The reason is that all these games were meant to be played on an SDTV, which provides you with the video quality similar to DVD, and not the usual 16:9 widescreen that is seen on LED TVs these days.

Most of the AMD graphic cards as well as several from Nvidia come with GPU scaling, which helps a user to stretch these 4:3 aspect ratio games to the now-standard 16:9. Once you have turned on GPU scaling, you can enjoy your childhood favourites on your regular widescreen with a bigger aspect ratio of 16:9.

With the current monitor market on the rise, GPU scaling is a need of the hour if you want to run an old game or software.

Types of GPU Scaling

There are three types of GPU scaling available

  • Preserve Aspect Ratio: This does not change the aspect ratio of the game. It adds black bars at the sides
  • Full Panel: This mode will stretch the 4:3 aspect ratio to a 16:9 ratio. The images might seem a little distorted as the video was designed for a smaller aspect ratio and has been stretched.
  • Centre: In some cases, the resolution of the game is much smaller, and one can use the centre mode for GPU scaling. This adds black bars both at the top and bottom so that the video is displayed in the middle of the screen.

How to Enable GPU Scaling?

Top 7 cheap Graphics Cards under INR 5000 that get the work doneSystem equipped with AMD Crimson (or later) software and a compatible AMD graphics card, follow these steps: Open your AMD Radeon settings > Click on Display > GPU Scaling. You’ll find the setting to modify GPU scaling setting in Nvidia’s control panel under Adjust desktop size and position.

To enable GPU scaling, you need to connect your monitor to the graphics card directly. This can be done via DVI or HDMI.

Increased input lag

When GPU scaling is enabled on a device, it could increase the input lag as the GPU has to perform more processing due to compressing or stretching the image.

This input lag is mostly in the order of milliseconds and is not easily detectable by the human eye. GPU scaling is a great feature which provides a better feel of playing older games on widescreens.

That’s it. Now you can enjoy working and playing Contra and the likes via the GPU scaling.
