I’ve got an TV (plugged to my pc with hdmi)
and a normal monitor (which is plugged into vga).
I want my monitor to act as my chatting, writing, surfing platform and my TV for displaying movies e.g. DVDs.
Is there a way I can apply the hardware to the multiple desktops available in KDE?
Click the application launcher (Kmenu or “start button”) then go to Configure Desktop (Personal Settings). Under the category Computer Administration, click Display then choose one of the monitors for setting to the right or left of the other. Keep one absolute. Then apply the settings. You can also fool around with the settings just to see what works best for you.
