Debris-filled or faulty HDMI ports, overheated consoles due to clogged-up air vents, hard drive failure, or damaged hardware are some causes of this problem.

Key Takeaways

  • The reasons behind it include hardware defects, system firmware bugs, improper connections, or incorrect configurations.
  • To fix the error, try replacing the damaged hardware, checking the cables, connections, and ports for any faults, or power cycling, upgrading, and cleaning your consoles.

Tip: Power cycle Xbox, fix or replace damaged cables, properly link to HDMI slots, select the correct HDMI on TV, update Xbox, and clean the Xbox before moving ahead.

Modify The AVR Settings On The Xbox

The Audio-Video Receiver (AVR) lets you connect different devices to your Xbox for screening purposes, such as streaming games on your TV. Re-establish the connection and ensure you have picked the same HDMI port on which you connected the device.

  1. Power On Devices: Turn on the TV and wait for the display > Turn on the AVR > Power on the console.
  2. Re-Select HDMI: Switch away from the current HDMI selection; for instance, if Xbox is linked to HDMI 1, switch the TV to HDMI 2, and then back to HDMI 1 > Restart AVR.
  3. Pick Display Settings: Go to Xbox Settings > Highlight General > TV & Display.

Xbox Support also offered this method to troubleshoot blank screen issues that could be linked to an HDMI port.

Launch In Low-Resolution Mode

Starting Xbox in low resolution is an effective way to troubleshoot display issues. Doing so helps identify whether the problem is related to the Xbox graphics or something is wrong with the HDMI port or cable. Remove any resolution-related glitches with the following method.

  1. Navigate To Display: Move to Xbox Settings > General > TV & Display.

  2. Modify Resolution: You will see multiple resolution choices, like 4K, 1080p, 720p, and more. I recommend that you proceed with Auto so the system can select the best-suited resolution based on the current situation to rule out this issue. Otherwise, proceed with a resolution lower than the current selection.

Disable The 24Hz Mode

With the 24Hz mode enabled, you can enjoy a cinematic experience on your TV. The 24Hz refresh rate allows seamless playback with perfectly synced audio and fewer lags.

However, it once disrupted my TV’s functionality, probably because the display could not handle the particular refresh rate, leading to errors. To counter this, I disabled the 24Hz mode on my Xbox Series X and then established the HDMI connection, which was successful.

  1. Access Video Modes: Navigate to Settings > General > TV & Display > Under Advanced, pick the Video Modes option.

  2. Allow Refresh Rates: First, uncheck the box, Allow 24Hz to switch off the configuration. Then, mark Allow Variable Refresh Rates to let the console select the appropriate configuration.
