Very happy with this display. I ordered it on Oct 3 and received it on Oct 6... super fast shipping. Great display, no dead pixels... bright, sharp. This display runs with no problem on my Mac Pro 5.1 using the standard graphic card the ATI Radeon HD5770. This display only has a DVI-D and requires a Dual Link DVI to drive it. The Radeon HD 5770 works just fine using the DVI-D output and the dual link cable supplied with the display. You can't beat the price and the display is awesome. One downside... it comes with a manual that is only in Korean... so no clue which butttons to adjust brightness or contrast.... it would be nice to have a translated manual...but right out of the box the color looks great. Bottom line.... good supplier, fast shipment, great price... whats not to like.
