I got a new GPU from my brother earlier today that had a HDMI output and a DVI output on it. I dont have a DVI monitor so i hooked it up to my T.V. When i hooked it up the screen was black for a minute then real quickly says "resolution mismatch! adjust resolution". my T.V is a magnivox and I dont know what the GPU is called (he said it was an AMD something). My T.V doesn't have DVI or VGA capability.
