Hi there and welcome
No it does not, it means that if you have a DNLA server set up your TV can play files from the hard disk of the computer.
You can see here how you would set up a DNLA server within windows
Then, depending on the model of your TV, you have different options on how to play that content.
If you do wish though to use the TV as a monitor, a much easier method is to use a special dingle called the Google Chrome Cast
You can get it here
You then connect it to one of the HDMI ports on your TV.
You can then wirelessly mirror the screen of your computer to the TV, or even cast services such as netflix and youtube from your phone to your TV, using your phone as a remote.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
