Thanks for participating in our online forum community here! I understand you're interested in hooking a PC up to a TV to view your Slingbox. That, honestly, depends on the inputs of the TV as well as the outputs from the PC. If the computer and the TV have VGA or HDMI inputs and outputs, then it shouldn't be a problem. We also have a SlingPlayer for Connected Devices which is a built in version of SlingPlayer that comes pre-installed on some third party devices which you can connect to a TV to view your Slingbox.
Here is an article from our support site with more details on SlingPlayer for Connected Devices:
Hope this helps!
