I have a slimline Dell XPS 210, and was curious if I could even hook it up to my TV and use the internet that way. I'm not sure if it needs an HDMI cable - I know this PC is archaic by 2014 standards, but still wanted to just see if it was possible. Any suggestions?
as long as your tv and videocard have the same output: (VGA, HDMI - DVI - DVID) you just need the cable to connect it and everything will work.
a tv is just a monitor, but sometimes it has a different cable, for tv's the most common cable is HDMI, pretty much every tv has one these days.
your best bet would be to check if you tv has a HDMI cable, and then just plug it into your videocard output.
