Ok I have bought a new PC, just arrived and i plugged it in and the screen resolution is stuck 800x600 and the screen is like this (see pic below) tried upgrading the graphics card its nvideo gtx 960 and it made no difference. I cannot plug DVI into my tv but can plug VGA and this graphics card does not have the option for this. Any help
