Hello fellow openSuse users!
I am running Tumbleweed with KDE5 on a HP Elitebook 8760w laptop, 16GB RAM, NVIDIA Quadro 3000M 2GB with a HP docking station.
My research has shown me that this hardware configuration is capable of running multiple external monitors along with the native laptop screen. I have even seen a video with four external monitors with this hardware.
I have two external Acer monitors attached, one via VGA, the other via DisplayPort, both with the same resolution 1680x1050.
I can activate one or the other, but not both concurrently.
From xrandr I can see that a maximum resolution of 16384 x 16384 is possible. However, the third monitor reports as connected, but will not activate.
System Settings / Displays also recognises the third monitor, but will not let me activate it, and reports:
Sorry, your configuration could not be applied.
Common reasons are that the overall screen size is too big, or you enabled more displays than supported by your GPU.
This is not correct, as I know all hardware works and is capable of running the two external monitors or even more. If all three were active, that would mean an effective screen width of 5280, which less than the maximum 16384.
Here is my xrandr output.
