Win8 RP - New driver 7.0b1 not working correctly with 3 monitors

[vlko]

Hi

My configuration is laptop with 1600*900 + 2 HD monitors where one of them works through i-tec Display Adapter via HDMI cable.

If I'm using just two HD monitors (one over usb display card) everything works fine or if laptop and directly connected HD monitor are in duplicate mode and second hd via usb in extend mode also works.

But if one primary and other two in extend mode I can see first failing image segments (like puzzled image) and then black screen. So simple all three together not works. Once I also got bsod error (attached).
