I have a 30” dell 3007wpf monitors and i have an asus x75a laptop, i was not getting a higher resolution through my laptop hdmi (laptop resolution 1600 x 1200) for some reason I was getting only 1280 x 800. I bought an external PCI express and put a nvidia nvs 315 to bypass the laptop graphics card but I am still getting 1280 x 800. I checked nvidia control panel and I show that the dell monitor connector is DVI but the video signal is Analog VGA. Does anybody have an idea why nvidia is not recognizing the digital signal?
