Problem with touch screen

[Peerl]

Hi ! I bought Thermaltake DH104 with SG7 touchscreen and encounter a problem with connecting touchscreen to a graphic card Zotac gtx285. This card has 2 dvi-out only. Tv Phillips 42" is connected to 1st dvi-out, and touchscreen display is connected to 2nd dvi out by dvi-vga adapter. When system starts, the "UNSUPPORTED" sign appears on the touchscreen and system does not boot. TV at this moment does not show anything. If I disconnect the touchscreen from the graphic carg, the system starts operating normaly. System with both TV and touchscreen display operates properly if the touchscreen is connected after the Windows begins booting and Windows logo appears on TV. My system sonfiguration: chassi - Thermaltake DH104, CPU - Intel i7 920, motherboard - Asus P6T, Graphic card - Zotac GTX285, HDD - Western Digital 1TB, DIMM - Corsair 3x2GB DDR3, Power supply - Thermaltake Toughpower QFan 850Wt

I'm pretty sure the SG7 LCD doesn't support connection via adatper, it must use a VGA port on the video card. Soundgraph, please correct me if this is incorrect, but I read in several reviews this was the case.
