Hi all,

I wonder if anyone can help with my predicament: I have a Dell 24" monitor and a Toshiba Regza tv, and what I would like to do is to output video playback (from VLC, etc.) to the tv only. Later on I might like to try games on the tv screen as well.

The Dell monitor is connected by DP and the tv by HDMI. I have read lots of guides online but cannot seem to get any program to output to the tv. For example, if I set 'X window' on VLC to :0.1, it still outputs to the monitor rather than the tv.

nvidia-settings detects both monitors with no fuss.

My modified xorg.conf looks like this:

My system is OpenSUSE 42.1 with KDE Plasma 5.8; video card is a GTX 970.

Clearly I have missed something with the config but I would appreciate some help :-)
