My notebook is Latitude E7270-Windows 7 Eng x86, when I update the display card to latest-Intel HD VGA..., the screen will often turn to black and prompt out "display driver stopped responding and has recovered", I have try to add TdrDelay:8 in regedit. Same error occurred. When I uninstall the driver back to Standard VGA Graphics Adapter, this error disappeared, but I can not insert the external monitor to its docking station after use the standard driver only.
How can I resolved this problem? Thanks.
Dell laptops require the customized Dell drivers not Intel's which are generic. Reinstall the original Dell driver from Dell Support.
