What to look for before connecting an AIO PC to a TV HDMI?

Since AIO machines are made very thin and compact, they will not have big hardware. This means that there can be some limitations to the usage of AIO with the TV. Therefore, here are the factors to consider before connecting AIO to TV.

  • Graphics Card Capacity – AIOs are usually built with integrated graphics which have very less video memory which hiders the ability to perform highly intense graphical tasks. This means that you cannot connect many monitors to the AIO. So, if you already have multiple monitors connected to the AIO, check whether it will give output to the TV when it is connected to it. 
  • HDMI support – Although there are more chances that your AIO will have HDMI and your TV will also have it. But it is better to check its availability and compatibility. It doesn’t have to be the same generation to produce an output. But if they are the same gen ports, you can have better video and audio quality.
  • Distance Between the devices – If your AIO is far away from the TV, then you might not get a long cable to connect them without changing their positions. You might have to move one of them closer to another.
  • Port location – The location of the port in your AIO will be easily accessible. But your TV might have the port at the back and if you have wall-mounted it, connecting the cable might be quite difficult.

These are the factors you have to consider before connecting the AIO PC to the TV via HDMI.
