Xbox randomly went into widescreen and wont go back to full screen.

Hello, how are you? My name is Mateus. I'm an Independent Advisor and I'll be glad to help you today.

First, welcome to the Xbox community, and we're sorry you're having this issue. Seeing what problem you are having I suggest you try the steps below before we try any different solutions.

Try testing your console on another TV or Monitor if possible

Change the HDMI port your console is connected to the tv and also the console itself

Try plugging the console directly into the power outlet, without using a line filter

Try testing the console on another power outlet

Try using another HDMI cable if possible

- If none of the above steps solve the problem, I suggest you try the solutions below.

'Solution 1:

Step 1. Press and hold the Xbox button on the console for at least 10 seconds to open the Power center.

Step 2. Then unplug the power supply from your console and wait for 3 minutes.

Step 3. Plug the power supply back into the Xbox console.

Step 4. Press the Xbox button on the console to turn it on again.

Solution 2:

Press the Xbox button on your controller to bring up the guide menu. Once you see it, use it to access the Settings menu.

Once you’re inside the Settings menu, navigate to Display & Sound > Video Output > Video Fidelity & Overscan.

Once you're inside the Video Fidelity & overscan menu, look under the column listed as Display and you should see a TV connection with a drop-down menu. By default, it’s set to Auto-Detect (Recommended). To fix the issue, change it to HDMI, and then confirm that you want to override your TV settings.

After you manage to complete and confirm the operation, return to the Display menu and change the resolution normally. You should now see the full list of available resolutions (not just 640 x 480).

*Thank you in advance for contacting, I hope this can help you.

Wont know until we get there, but lots of modern Blu-ray players offer the full screen or widescreen option these days, so your chances are reasonable.

thanks i had the same question....lol i never even noticed that

is this on live tv, or when playing a game? If it's on like tv, hit the menu button on your remote and then select stretch as your display mode. if it's not correct when playing a game, check your tv menu settings and make sure it's set to stretch

im having similar problems, no sound and the display settings are messed up, my screen looks like im using an old scart cable rather than a hdmi cable on a full hdtv. when i go to display settings, screen format is greyed out and cant be selected ands its
displaying an 1280x720 widescreen dvi. what the hell?
