Recently purchased a Dell T3400. The system has dual quadro NVS 290. I put the splitter cables together and hooked 2 monitors to one card and 2 monitors to the other slot. Only 2 monitors go live. The 2 monitors to the other slot don't go live. I have changed them back and forth, made sure I am on digital signal and noting works out of the one card slot. I also had an extra nvs 290 x16 and put it into the slot for the one that didn't work and the same thing happens. Am I missing something? Thanks
