Matrox triplehead2Go digital, half of screen disappears!

[pappavis]

Today I hookedup a third screen to my Matrox Triplehead2Go Digital.

 

BUT, on monitolr#2 there is a 25% 'black' hole. Also, about the same amount of image is not displayed on monitor#3.

When I use the monitor VScaling, its possible to scale left but thats only difference of about 5%. Is it something todo with Bezel, if so how can i change it?

 

Desktop is stretched 5760x1080

Drivers: all the latest, also using Matrox PowerDesk 2.07.

Videocard: Nvidia GTX460

Monitors: * 3x 24"LEDs capable of 1920x1080 HD (connected to DVI#1).

1 x 10"touchscreen (connected to output DVI#2)

 

SCREENSHOT --> look the black vertical section on monitor#2.

I found the Bezel mangement, but cant manage the middle monitor or #2 as its connected onto the TH2Go box!

I wanna change the MIDDLE screen,so that the image area moves <>220pixels to the left!

 

When adjusting the middle bezel it can only move to bezel the right, so the frigging blaack area just gets bigger. WEIRD is

* Selecting display of 3840x1080 all oke, no black bezel area, but then my third screen is disabled :(

* black area = displysize of 5760x1080.

* Switch to a lower res like 4890x900 then there is no black bezel area.

* My videocard output#2 is to a 1440x9000 monitor. Any vertical res higher than 900 looks to give a black area. WTF?!?
