When you update the Graphics driver, did you install the generic driver or did you install Dell’s Driver?
It is important to mention that we sell our Intel chipsets and processors to third party manufacturers and they design their own computers with their own features, settings, and capabilities.
For that reason they design their own drivers, to meet the exact specifications on their computers. If your computer is having problems with our generic Intel graphics drivers, the best you can do is install the latest customized driver released by your OEM Dell (Original Equipment Manufacturer).
