I have an HDTV at my place and also a computer in the same room. I was thinking if I could connect the HDTV to my computer and use it as a monitor. This would help me watch movies and videos on a bigger screen. But the problem here is that the computer has the VGA output and the HDTV has the DVI-D post as the video interface. I think I need some sort of converter that converts the DVI-D to VGA. But I have no idea which is a good one to buy and also where can I buy them online. So please help me on above.
