I have an Asus G73SW that I have been playing games with via the HDMI on my TV. It has worked fine for a while now. Today, it will not work.
It will give the Windows device sound when I plug in the cable (doo duu!) but the screen on my TV will not change. It remains "No Signal." I tested the HDMI port on the TV via my DVD player, and it's working correctly. I also replaced the cable thinking there might be some interruption, but nothing changed.
It went to:
''Control Panel\Appearance and Personalization\Display\Screen Resolution''
and tried to "Detect" and it shows "1|2. Multiple Monitors" but still nothing on the TV.
I have not installed any updates or drivers
etc. Maybe I pushed the wrong FN combo in my sleep? FN/F8 shows the "Laptop" on the first press, on second press, it shows "HDMI" and the laptop screen goes blank, but no signal goes through to the TV. Previous to today, when I plugged in the HDMI, it auto detected and I never had to cycle through FN/F8.
Edit: I installed the latest Nvidia Driver
setup and there was no change. I also restarted with the HDMI plugged in, but it only displayed the same "No signal." Windows mobility center does recognize the Display as being connected.
