So, I have 1 GPU with 3 outputs and 3 displays. Do I have to buy a second GPU to connect 3 other users?
I read the FAQ carefully:
To run workplaces you have to link a monitor. However you may simulate a connected monitor by means of a dummy panel, or if the monitor has several interfaces (for example, VGA+DVI), you may connect one monitor several times, in doing so you may switch between workplaces just by selecting a required signal on the monitor.
My question is rather to know if: 1 GPU output = necessarily 1 user?
Yes, sadly you need multiple GPUs for multiple users no matter how many outputs your single GPU provide.
Just a side note to make it clear:
You have to then connect displays to the correct GPU (eg. GPUs A and B and displays Da1,Da2 for first user and Db1, Db2 for second user --- have to be connected A: Da1, Da2 and B: Db1, Db2, this is the only option, you cannot connect A: Da1, Db1 and B: Da2, Db2)
This is possible however your motherboard need to support 3 monitors with its iGPU and a graphics card capable of running 3 monitors
like GTX 1060
