HDMI Source Incorrect

TV Source Input

If your TV is showing a blue screen when you are trying to use an HDMI connection, the first thing you should do is check that the input source on your TV matches the device you are connecting to.

To do this, look for and select the correct HDMI port on your television’s menu. If there are multiple ports available, double-check which one will work best with your device.

Once you have selected the right input source, try reconnecting it to see if that resolves the issue.

Quick Note: The most common cause is that the settings of the HDMI source may not be properly configured. You should try adjusting the settings on both devices and then see if it helps resolve the issue.

Loose HDMI Connection

Loose HDMI Cable

Another possibility is that one or more of your cables (HDMI cable, power cord) might have been damaged or disconnected in some way.

This can lead to poor connections between devices and result in a blue screen.

To fix this, make sure that all the cables are securely connected to their respective ports, and then try turning on the device again.

Wrong TV Resolution Settings

TV Resolution

Make sure your TV settings match your device’s output resolution, otherwise, the image may not display correctly on your screen.

A lot of the time, you will see bluescreen on your TV when you use it in combination with a projector, PC, laptop, or a monitor with HDMI.

Incompatible Device

Apart from configuring the picture settings of your TV for a particular input source and device, make sure the other device which you are trying to connect with your TV over HDMI is compatible with it.

Because device compatibility issues are mostly neglected in such cases and that’s why ensure your device is compatible with your TV’s input ports and supported resolutions before connecting them together for use.

Firmware Update

If the blue screen is still present after replacing or reconnecting your cables, you may want to check for any firmware updates available from the manufacturer.

It’s possible that an outdated version of the software could be causing compatibility issues with your TV and HDMI setup.

To do this, visit the manufacturer’s website and look for any downloads related to your device model.

Damaged HDMI Cable

Finally, if none of these solutions have worked so far, it might be time to take a closer look at your HDMI cable.

If the cable is damaged or worn out, it could be causing the blue screen on your TV.

Try replacing the cable with a new one and see if that resolves the issue.

Faulty HDMI Port on TV

If you are seeing a blue screen on your TV when connected to an HDMI port, it is likely that the port may be faulty. This could be due to physical damage, or a loose connection, whether it is due to a faulty HDMI cable or the HDMI port of the TV itself.

To check if this is the case, try connecting your device to another HDMI port and see if the issue persists.

As for ensuring that the HDMI cable is in good condition and works, how do you do that? Don’t worry, I’ll cover that next.

One of the most common causes of a blue screen on your TV when using an HDMI cable is a faulty or damaged cable.

To make sure that your HDMI cable is working properly, there are several quick tests you can perform:

  • Test for physical damage- Visually inspect the ends of the HDMI cable for any signs of fraying or damage. If it looks worn out, replace it with a new one.
  • Check connection- Make sure both ends of the HDMI cable are firmly connected to their respective devices – your computer and your television set. Also, check if all pins at each end are in proper alignment with no obstructions blocking them from connecting properly.
  • Troubleshoot settings- Check that you have selected the correct input source on your TV and also that audio/video settings such as resolution, refresh rate, etc match between both devices (TV and laptop).
  • Try another device – Connect another device to see if it works through this same port & cables. This will help determine whether there is something wrong with the ports, cables, or settings specific to only one device versus across multiple devices.
