Black screen on TV when connecting PC via HDMI

Black Screen on TV When Connecting PC via HDMI:

Fixing a black screen on a TV:

If your television has a black screen, you may need to try to reset it to its factory default settings. To do this, refer to your television’s user manual.

If the black screen persists, the cause may be a problem with the motherboard or one of its control chips.

This type of component repair can only be performed by trained technicians equipped with state-of-the-art electronic diagnostic equipment.

First of all, make sure that your TV is compatible with your PC. If not, the resolutions of both devices may differ.

Make sure that you’ve connected both power cords to the TV and display cords to the PC. Sometimes, a Samsung TV’s service menu will fail to detect a signal from the PC via HDMI, leading to black screen symptoms.

Changing the HDMI cable Black screen on TV when connecting PC via HDMI:

If you are getting a black screen on the TV after connecting a PC via HDMI, you may want to try changing the cable. You can do this by pressing the Windows Key + ‘P’ on your keyboard.

This will cycle through different display modes. For example, you can select duplicate mode if you want your TV to mirror your monitor, or you can select extended mode to treat the TV as a second display.

First, check whether the HDMI cable is seated properly in both the TV and the PC. Also, ensure that the cable is powered on.

A broken cable can cause a black screen on the TV or a USB connect/disconnect noise. Another cause is a loose or damaged joint between the HDMI cable and the TV.

Checking the source device’s video resolution:

To ensure a proper video output, you must check the video resolution of the source device before connecting it to your monitor. This will help you ensure that your external monitor is capable of receiving the highest resolution possible.

If you find that the resolution is not adequate, you can manually configure the source device to produce the highest resolution possible. However, you may need to perform this procedure each time you connect the monitor and PC via HDMI.

Often, the problem stems from a faulty HDMI cable, a loose connection, or the wrong display settings. If these are the causes, you can try reconnecting the cable and trying again. If these steps do not work, you can try cleaning the port with canned air.

Checking the monitor’s refresh rate Black screen on TV when connecting PC via HDMI:

If you are connecting a PC via HDMI, you need to check the monitor’s refresh rate. Many people don’t know what their monitor is capable of, but there are some easy ways to find out.

Check the DP and HDMI versions of the monitor, as well as the display settings. A higher refresh rate will ensure better performance.

If your monitor’s refresh rate is lower than 120Hz, the problem might lie in the graphics card. An older graphics card may not have enough power to support this.

Make sure you check the settings to make sure you have enough power to support the higher refresh rate.
