Just bought Toshiba 62HMX84. Has 2 HDMI inputs. Want to hook up my PC using DVI to HDMI cable, but sheet attached to the manual states clearly not to hook up a PC. What gives? If I set my PC to 1024x768, won't it be able to scale it to 720p? I don't mind a little truncating, or top/bottom/side bars. Is it a problem with the refresh rate? I can adjust the PC refresh rate manually, if that makes a difference. Has anyone tried it? Don't want to burn up my set if someone has already learned the hard way.
