Background:
PC had no GPU (mobo: ASRock h61m-dgs) so plugged in the new Nvidia Quadro FX1800 (quite old, but shouldn't see why it wouldn't work). Had no DVI cable for monitor, only a VGA to VGA which I kept plugged into the mobo. Turned PC on, fans work on GPU, but monitor didn't turn on. Plan 2: connected HDTV up using a DVI to HDMI cable. Turned on fine, although display settings were off and didn't go as high as 1080p. Next step: install drivers (downloaded from Nvidia website and installed using the executable file). Required restart and upon restarting, mobo (and BIOS I think it's called) loads but the screen on the TV goes blank.
Any idea what I'm doing wrong here?
