Screen resolution/no sound

Thanks for the reply. Unfortunately still no resolution.

To clarify the problem - it occurs on power up when at the home screen. Tried to adjust resolution again.

4K results in a screen saying there is a problem.

1080p results in a blank screen that then goes back to Display & sound.

720p goes to a screen that asks if i want to keep this resolution but it goes black.

Im going to assume you are referring to the resolution being displayed by your console on your screen (obv😉) and you would like to change it to a higher resolution.

Firstly: Is this the native resolution of the screen being used, and is it the highest capability of said screen?

Secondly: To change the setting on your console simply follow the steps outlined in the link provided below. Hope this helped with your issue.

What do you have your display settings set to on your XBox 360? I would start with 480p and work your way up to see if the problem is the screen resolution on the flat screen tvs. It sounds like maybe there is an incompatibility with the tv and the XBox
360 on the flat screens you have the problem with. Are these flat screen tvs new? What is the max resolution on the tvs?

Hello Rubens,

Thanks for reaching out to the forums. We see you have an issue with resolution. The screen size could also be your TV settings. Here is all we

got on TV resolution.

Thanks,

Brad

If your TV is shutting down, then the problem is with the TV. It sounds to me like your scaler chip is failing. The black screen is the Xbox changing resolutions. You should contact their support.
