Direct3d is not working and driver disables it for all cards

[Erwinus]

Hello,

I have here a Gefen USB2DVI Adapter (EXT-USB-2-DVI) with following specs:

Mainboard: AN2410D1 - REV:1.14
Displaylink Chip: DL-160 / 230896A0 / F2630E / QH4MH-A / 0734 AA TWN
DVI-Chip: Chrontel CH7301C-TF / GUC 0742 / MPP5Y
(Flash) Memory?: trontech em6a9160ts-5g

I want to know if the DL-160 can support direct3d, because the newest drivers (6.3 and 7.0) supports it but is not working correctly. Site effect is also that direct3d is not working for all cards after installing these drivers. Uninstalling the drivers will restore the Direct3d functionality for other cards.

For me it is not really important that the DL-160 will support direct3d but must not influence the behaviour of other cards! Blinking screen (4x times) when want to try Direct3d. This is very annoying. I'm not using the USB-Card the whole day so want to keep this driver installed (and not each time i want to use a third monitor).

My screen setup:
- Main notebook screen 1920x1080
- Second screen 1440x900
- Third screen 1280x1024 (USB Displaylink)

My system info:
ASUS N76VM Notebook
Windows Home 7 with DirectX 11 installed
Intel ivy Bridge Chipset i7
i7 Quad Core
Video1: Intel HD Graphics 4000
Video2: NVIDIA GeForce GT 630M


Thank You for your reply!

I think this was a known issue in v6.3 which should be fixed in v6.3 M1. Could you try the new release please?
