A very dear friend gave me a Vizio flat screen TV, and I decided to set it up as a monitor for my computer. I hooked it to my PC using a VGA double-ended cord, but my gfx card takes a DVI connector, so basically my system goes TV > VGA cord > VGA/DVI adapter > gfx card.
Now for the problem: I have no red. Every color is just a mix of blue and green. Anything that is red shows up as black. Is this likely an issue with the cord setup, or is there something wrong with the TV? It plays normal television (over an analog cable hooked to cable TV) with fine colors. Also, sometimes when I first turn it on using the computer, the red shows up right, then suddenly winks off and leaves me with the awful blue-green. Any suggestions?
