The PlayStation 5 launched with 4K and 1080p output modes, but the ability to output 1440p has since been added via a firmware update. This output bridges the gap between HD and 4K displays, but there’s one drawback you should be aware of.
In display terms, 1440p refers to a resolution of 2560×1440. It’s a middle-ground between the higher UHD or 4K resolution (3840×2160) and HD or 1080p (1920×1080). It’s commonly used in computer monitors, where you may hear it referred to as QHD or 2K. Some of the best gaming monitors have a resolution of 1440p.

A lower resolution better suits less powerful mid-range gaming PCs, since 4K can be very demanding on the GPU but many gamers are past the point of 1080p. 1440p monitors are often thought of as a “sweet spot” with higher refresh rates at more competitive prices, which can mean smoother motion during gaming and work.
In 1440p mode, the PS5 will either output a native 1440p image (in supported games) or downscale a “supersampled” 4K image to fit a 1440p display. It’s always been possible to connect a 1440p monitor to your PlayStation 5, but previously this relied on an inferior 1080p image being upscaled by the monitor.
This mode is mostly aimed mostly at PC gamers (or those with a compatible monitor) who want to make the most of their display’s full abilities. If the monitor is capable of high refresh rate gaming at 120Hz or better, the PS5 can take advantage of that in this display mode too.
You can put your PS5 into 1440p mode by visiting Settings > Screen and Video Select “Test 1440p Output” and run some tests on your monitor to see whether your monitor is capable of outputting the full gamut of
