My older pc connected to a LG Hdmi tv via dvi to hdmi converter. Pc screen shows on tv, then I get no signal and invalid format..why does it do this and how do I make it stay on my pc screen? Is it the resolution on my pc that is causing this? If so please tell me what it should be set at. Help please thank you =)
