The Nvidia 4x AGP geforce fx go5200 32MB DDR graphics card in my 12" powerbook g4 1Ghz running 10.4.11 runs this monitor over DVI at it’s optimum 2048x1152 right out of the box with no problems. This card supports only single link DVI, but the DVI on this monitor is also single link, which one immediately sees from inspecting the DVI cable that comes with it. It also works well at 1920x1080. I also tried the VGA interface and was unable to detect any obvious difference while surfing or wordprocessing. I’m also able to run the webcam using Skype. The viewing angles on this monitor are a bit on the small side. I haven’t noticed the high frequency hum that some have said occurs when brightness is adjusted downwards.
