My computer monitor went out, and so I found a used (2008) Insignia 32" lcd tv to use instead. I am using a vga cord. My video card is a Radeon x1300 with updated drivers. Win. 7 installed. The problem is I can only get 1024X768 as a max. resolution. Will upgrading the video card fix that, and get me the 1280x1024 res. that I want, or is that all the tv will handle?
