Connecting the PC to the TV

1
Connect one end of the HDMI cable to the PC. The HDMI slot is usually behind the CPU if you have a desktop computer, or on the side of a keyboard on a laptop.
- Some PC's may use a regular HDMI port, while others will use an HDMI mini or MiniDisplay port.
- For HDMI mini and MiniDisplay cables, one end of the cable should be an HDMI mini or MiniDisplay cable which you can plug into your computer, and the other end should be a regular sized HDMI cable.
- Not all computers have an HDMI port. Some older computer may use a VGA or DVI cable. You can connect these to the HDMI port of a TV using an adapter and a separate audio cable. If you are using a laptop that does not have an HDMI or other video-out port, you can purchase a USB-to-HDMI adapter. You may need to install additional software on your PC.

Connect the other end of the cable to the TV. Find a free HDMI port on your TV and connect the other end of the cable to it. The ports are usually numbered and labeled with "HDMI".
- Make a note of which HDMI port you are connecting to.
- Make sure you purchase an HDMI cable that is the right length needed to connect from your PC to your TV. Measure the distance if needed.

Use the TV remote to select the HDMI source on the TV. Look for a button on the TV or remote that says "Source", or "Input" or something similar. Use this button to select the HDMI port you connected your PC to.
- After connecting the PC and TV together, sometimes the TV will automatically display what’s on your computer monitor. If it is blank, use Method 2 to detect your TV in Windows 10.
- Use the number labels on the HDMI ports to help you find which HDMI source your computer is connected to.

Can I hook up the TV monitor first and then hook up the regular monitor for my desktop?

Yes, actually, if you have enough outputs. Have the television connected to the 1 output, boot up the PC, attach the secondary monitor, go to graphics properties, and adjust the monitor settings to your preference.

Do I have to connect HDMI to the graphics card HDMI or the PC HDMI?

In most cases, you should use the graphics card, because the PC HDMI is often disabled. Some PCs allow you to use either connection, so it depends on your computer.
