Changing the resolution on your X1 TV Box
You can easily switch between higher and lower resolutions on your X1 TV Box — including to 4K UHD.
From within a program’s info panel (after pressing the Info or i button on your remote), you’ll see a Watch in 4K UHD, Watch in HD or Watch in SD button. Selecting the available option will change the program to your desired resolution.
Notes:
- If your Prefer Best Available Resolution setting is set to on, you won’t be able to downgrade the resolution on your X1 Box.
- You’ll only receive the 4K option if you have a 4K capable Xfinity TV Box and 4K capable TV. For more information, see 4K Ultra HD (UHD) and High Dynamic Range (HDR) on Xfinity TV.
