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).
Could you please attach a picture for better understanding?
thank you for replying to me!
And I do appologize for my late reply to you!
I have installed the OEM drivers recently,and now everything is working like a charm!
Thank you for your help!
