Hi,

I'm having a problem with my dual-monitors setup.
My system is GIGABYTE GA-F2A85X-UP4 motherboard with AMD A10-5800K APU (no discrete graphics card). Windows 8 x64 is installed.
The 2 monitors are Samsung TV and DELL monitor.

The problem started from yesterday. Everytime I switched off the Samsung TV, the DELL monitor also went off as if there was no signal going into the monitor.
It did not matter what mode I set to (duplicate, extend, single monitor), as soon as I switched off the TV, the DELL monitor (primary display) went off.
The problem did not happen initially. Initially, when I switched off the TV, it automatically switched to single display mode on my DELL monitor.

Please kindly advise.

Thank you.

I use the PC for media playback and web surfing.
When I don't watch movie, I want to turn off the TV and use only my monitor to surf web.
So, unplug the TV HDMI cable physically is very troublesome.

The thing is that I did not have this issue initially.
