I have a new Tv...and a new cpu with windows 7 64-bit. However my computer seems unable to find the tv-application. Indeed if i start up my cpu with the cable plugged in, it simply freezes in opening windows...is there some driver i dont have?
When you start up your computer, press f8 and look for a vga mode option. See if that can get you into windows and allow you to download and install the latest driver and see if that helps.
You might have to enter the T.V.'s menu and look for options for what hdmi...1,2,3,4,etc you have the computer hooked to and/or you may have to set the T.V. to computer.
