Let's see that model TV. Some are only 720p. If we set our PC to 1080, sure it might work then again you will see troubles. Let's see that model number in full.
Connection between my PC and my TV is lost when ever I press Ctrl Alt Delete, when my PC goes in to sleep mode or on occasion arbitrarily.
I have a 32'' LG TV with a HDMI cable hooked up to the first HDMI port on the TV, connected to a HDMI to DVI adapter which is connected to my graphics card.
My tv has the latest firmware installed, my PC has the latest video drivers. My TV is also set to "PC".
I am running Windows 7 64 bit and have a 260gtx.
A fix currently works to reestablish connection which involves hooking up my smaller PC monitor then hooking up my 32'' TV again. Although, this is a nightmare.
