Check if your motherboard is set up to support HDMI

Most motherboards today come with HDMI, but there are some that do not support the standard. Does your motherboard support HDMI? If not, it is possible that there may be an issue with your motherboard, graphics card, or monitor. The type of device you are using to connect to the computer will play a factor in what you might need to do to get your computer working again.

Video Card

Check if the graphic card is properly plugged into the motherboard and that it’s not faulty. If your video card was removed, check that it’s seated properly and securely in its slot. The graphic card is plugged into the motherboard properly, but the HDMI port on the motherboard isn’t working. Try troubleshooting your motherboard first to make sure that it isn’t faulty or damaged before replacing the video card.

Cables

Check all cables for wear and tear and check for physical damage, such as cracks or tears. Try replacing any faulty cables. Ensure the cables are installed correctly by checking the connections – each cable should be making a clean connection without any bent pins or loose connectors. If you have an older computer that has been upgraded to Windows 7, make sure your motherboard is compatible with this operating system. You can find out if your motherboard supports Windows 7 here.

Power

Check power supply unit (PSU) voltage using a multi-meter (the voltage must be within spec). Replace any faulty PSU units with new ones. Make sure you have enough spare PSUs to cover all of your equipment needs. If possible, use an uninterruptible power source if there is no backup generator available.

Can I Use HDMI on My Motherboard?

HDMI ports are the most commonly used connection on televisions and monitors these days, but how do you use HDMI with a computer? The answer is simple. Although it may sound counter-intuitive, you can use HDMI cables to connect your monitor to your motherboard. This technique will not work for all motherboards, so be sure to double-check compatibility. To make this happen, simply plug in one end of the cable into the port labeled “Display Port” or “DVI.” Then, plug the other end of the cable into the port that says “VGA,” which should already be connected to your video card. If you have an older VGA connector, then just leave it plugged in as well. Now, if you want to play games, movies, or watch videos while using HDMI, you’ll need to buy a new graphics card.
