It might come as a surprise to some, but the Xbox Series X system software continues to display the dashboard including the Home screen, Guide and other elements in a mere 1080p resolution. The console, of course, can run games at up to 4K 60 fps with real-time ray-tracing capabilities.
The new update, unfortunately, is only currently available to Xbox Insiders who are signed up to either the Alpha or Alpha Skip-Ahead Xbox Update Preview rings. The changes will bring higher native resolution and increased sharpness and text readability which will be particularly handy for Xbox Series X gamers who use 4K TVs.
Xbox Series S owners are currently out of the loop even though the Series S can also technically support 4K resolutions. As you would expect of a pre-release build, there are bugs and known issues that Microsoft’s engineers continue to work on. You can get the full run down on the update at the link to the Xbox Insider blog below. Hopefully, it shouldn't be too long before we see the update roll out to all users.
Buy the Xbox Series S console from Amazon for US$499.
