Dell M4400 display models
I recently ordered two Dell Precision M4400 laptops. Upon receipt of the laptops I was slightly surprised that there were different panels in each laptop: First order: X864C Module, Liquid Crystal Display 15.4WX+, WLED, Lg Philips Lcd Maybach/Avia Second order: U609C Module, Liquid Crystal Display 15.4WX+, WLED, Au Optronics Corp, Maybach/Avia Thankfully both are matte anti-glare displays and the quality is comparable :-).
