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 :-)
As long as xorg is recognize your 2x monitors you can do anything you want with the outputs.
The easiest thing is to use Window Rules from Plasma
Will try Window Rules so thanks for that suggestion.
