The Steam Deck has a healthy amount of resolution options to help you squeeze performance and customize your game experience, handheld or docked. Here’s all you need to know about the Deck’s resolution settings.
What’s the Steam Deck’s resolution?
The Steam Deck’s native resolution is 1280×800 which is almost the same as 720p resolution.
The 1280×800 resolution results in a non-standard 16:10 aspect ratio, compared to the more universal 16:9 in gaming. Games that don’t support 16:10 natively will have black bars on the sides of the display.
The Steam Deck’s screen is 7 inches across, making the Steam Deck’s PPI similar to the Nintendo Switch.
Steam Deck resolution when docked
The Steam Deck supports resolutions up to 4K (3840 x 2160) at 60hz when docked. Here are some key resolutions and refresh rates that the Steam Deck can support via HDMI 2.0:
- 3840 x 2160 @ 60Hz
- 2560 x 1440 @120 Hz
- 1920 x 1080 @240Hz
Keep in mind the Steam Deck is designed to run games at 720p, so the Deck will have quite the challenge of running any games at these high resolutions and refresh rates.
Steam Deck resolution settings – how to change resolution
In docked mode, the Steam Deck will default to the screen’s resolution, so if you dock your Steam Deck to a 4K TV, it will default to 3840 x 2160.
To change the resolution in docked mode:
- Click the Steam button and head to settings
- Then click on Display
- Under external display scaling find resolution
- Set to your desired resolution
Keep in mind that even if Steam Deck can produce a 4K output, it will likely not be able to drive games at 4K, I would suggest using 1080p as a target for external displays.
In handheld mode, the Steam Deck does not allow you to change resolutions
How to force resolution settings for games
You can set individual resolutions for every game on the Steam Deck:
- Open the page of any game you have installed on the deck
- Click the gear icon and then into properties
- Under general, set whatever resolution you’d like to play at
Force resolutions is useful because AAA 3D games have different power requirements than a 2D side scroller. You could enjoy a 2D game at a higher resolution while making sure that the 3D games still have decent performance.
Forcing resolutions could also be useful if there are games that are fussy with resolutions, forcing it is a good way to maximize compatibility with the Steam Deck.
Steam Deck and FSR
FSR stands for FidelityFX Super Resolution, it’s an AMD tech that uses machine learning to upscale gaming resolutions in real time without any hit on performance. It works in a similar manner to Nvidia’s DLSS.
For example, FSR can take a 720p resolution and upscale it to 1080p with minimal impact on performance, giving you a sharper game while maintaining fluidity.
Some games support FSR natively. In the Steam Deck you can force FSR through quick settings.
- While in a game, hit the Quick Access Button (…)
- Navigate to the performance tab, it’s a battery icon
- Scroll down to scaling filter
- Select FSR for scaling filter
- Pick an FSR sharpness level
- Drop your in-game resolution lower to improve performance
- Tweak to your liking!
