How can I connect my PC to my HDTV? I know it's possible to connect my PC to an HD screen, but I'm not sure what hardware I need to do to make it work.
I've covered a couple of variations on this in the past, talking about using an HDTV as a PC monitor and which connection you need to go from a PC to HDTV, but this time, I'm including a video to walk through the process. For most HDTV screens purchased in the last 2-3 years, you need to make a connection from a DVI out on your PC to an HDMI in on your HDTV. If you currently use onboard video on your PC (as in you didn't buy the more expensive video card option when you bought the computer) there's a strong possibility that you'll need a new video card. For cabling, choose between either a cable with DVI on one end and HDMI on the other, or an HDMI cable coupled with a DVI-to-HDMI adapter. Either way, read this article on how to not overpay for HDMI cables.
