Second monitor no longer detected, please help.
Firstly, I'd like to apologize if this thread is in the wrong place.
I am currently running Windows 7 Ultimate x64 and up until now had two monitors, my Acer monitor and a Toshiba TV I use as a second monitor through HDMI. However, one day after work, I had noticed that my Toshiba monitor was no longer being detected by Windows.
I have tried several things, including:
Reinstalling graphics drivers for my 5850
Using another HDMI cable that I know works
Unplugging and restarting both the desktop and TV
System restoring to when both monitors worked
Any help with this issue would be greatly appreciated .
