Cant enable more than 8 monitors in Windows 8

[daka]

I try to create square 3x3(connected to Displaylink) with 1 additional monitor (Connected to graphics card Nvidia GT720, and i encountered this limits. I can separately switch on each monitor, or 1 (on Graphics card) and other 7, but not all 10.
When i try to switch on 9th monitor it blinks switch on and switched off again.

Can you explain - it is windows 7 limits? Videocard limits? Resolution limits or displaylink limits?

PS. This video shows connention over 8 monitors is possible.

Hello,

It could be a limit from the graphics card, or from Windows.
This would not be because of the number of monitors, but the number of pixels.

What is the resolution of the total desktop you are trying to achieve?
Have you tried lowering the resolution to see if the 10 monitors fit?

As the video from Plugable shows, they ran 14 monitors. You'd need quite a graphics card and good USB throughput available to drive all that though...

Kind regards,
Alban

Yes. I tried to set less resolutuon. Not work.
Tried connect one by one.
Tried use other programs to swtch on 9 and 10 monitor - not helped.

Now i have 2 paths :
1. change graphic card
2. change OS. (now win 7, i want to try 8 or windows 10)

Even with the full desktop below 4000x4000?
