Troubleshooting

1. 
   1
   Make sure you have the right cables or adapters. Sometimes cables can have the right connections but aren't made for the purpose of carrying audio or video signals. Make sure the cable is rated for audio/visual use.

   • Most computers don't send audio output through the DVI port, so a DVI to HDMI adapter won't carry any audio in most cases. If so, you'll need to hook up a separate audio cable.
2. 
   2
   Make sure all the cables are connected properly. Check that all the cables are plugged in properly to the ports and not loose. If the cable has thumb screws, like most DVI and VGA cables, make sure the screws are screwed in and snug.
3. 
   3
   Check the volume. Check that the volume is up on both the computer and TV and make sure neither is on mute.
4. 
   4
   Change the audio output. If you're not getting sound, make sure you have the right audio output selected.

   • Right-click on
     
     .
   • Click Playback devices.
   • Select the correct audio output (HDMI output for HDMI, or Headphones if you're using an audio cable)
     • If you don't see the right output, right-click on any of the listed devices and make sure Show Disabled Devices and Show Disconnected Devices are both selected. This will tell you if the audio is disconnected or disabled.
5. 
   5
   Restart the computer and the TV. When all else fails, restarting the computer and the TV can help the computer to detect that a new display is connected.
6. 
   6
   Check your computer's display calibration. Sometimes, an error message will pop up saying "HDMI not supported", which usually pops up when your TV and PC have different display settings for resolution.

  Expert Answer

  You can buy a receiver that plugs into your TV's HDMI port, like Chromecast or Apple Airplay. Once you have that, you can (if you need to) download the correct software onto your TV and then connect the receiver to you home's WiFi network. Once you've done that, you just have to pair your devices and then you can use your TV through your PC.

  HDMI is the best option. However, some computers are not equipped with an HDMI output, in which case you'd use a VGA cable.

  Using your keyboard and mouse, the TV simply becomes the computer's monitor. You can purchase wireless keyboards and mice to hook to the computer to facilitate remote use.
