When the subject of next-gen console resolution come up, we hear a lot about 4K, but what about 1440p? Obviously the Xbox Series S will support 1440p, as it’s been specifically designed around that resolution, and Microsoft has said the Series X will support it as well, but what about the PlayStation 5? Sony has remained rather quiet on the subject. Previously, monitor manufacturer BenQ hinted the PS5 would support 1440p, but it seems they were mistaken.

According to IGN Italy, representatives from Sony have officially confirmed that the PS5 doesn’t support 1440p natively. Now, you’ll still be able to connect a 1440p screen to your PS5 and play games, but what you’ll most likely be getting is a 1080p signal upscaled to 1440p, which doesn’t always look great. This isn’t anything new – surprisingly, the PS5 Pro also only supported 1080p and 4K natively even though, functionally, a large number of its games ran at around 1440p.
