Toshiba LCD - No Signal DVI to HDMI

Hi all,

Hopefully this is the appropriate forum for this question. I've just transferred my video card to a new system I built (new motherboard, ram, case...old gpu, harddrive). The computer boots up, but I'm getting no signal on the tv. Could this be because of the new motherboard? Or maybe settings on my old harddrive conflicting with my new motherboard? Regardless..can't work anything out if I can't see anything on the screen. Any ideas or suggestions?

try hooking it up to a pc monitor. so you can ajust the settings to work with the tv

If its a TV more than a computer monitor Im guessing multipule inputs. Try checking all the input options on the lcd.
