I mainly use an external monitor (via HDMI) when using my XPS 15 (L502X), however, I noticed an annoying problem when I tried to update the Intel HD 3000 video card driver.
After I started my computer, when the display was automatically (by laptop) switched to external display, the laptop display was supposed to turn off automatically. However, with the new driver, the laptop display was off, but not completely off, it seems the backlight was still on (if you cannot see, here is the link https://drive.google.com/file/d/0Bwf8MXlJOZI3djhxeUlmdzA4djQ/view?usp=sharing https://drive.google.com/file/d/0Bwf8MXlJOZI3djhxeUlmdzA4djQ/view?usp=sharing).
I found out if I switched to the laptop display then back to external, the laptop display was off completely.
The original driver that came with L502X for Windows 7 does not have this issue though. The dell driver for Windows 8 has the problem.
Anyone has any solutions?
Info: OS: Windows 7, 10 (both have the same symptom)
Intel video card driver used that has the problem: the one comes with Windows 10, Intel driver 15.28.24.64.4229, the Dell one for Windows 8.
The only driver that does not have the problem: the Dell one for Windows 7
CPU: i7-2630QM
GPU: GT540M

The DirectX Diagnostics was collected with the Dell one for Windows 7. Not sure if change to the problematic one, the info will be different.

I think it is Intel driver issue, and no one would fix it?

Hello Wenbin,
Thank you for providing the system information report. Based on that information, I see your computer is running with an Nvidia card by default meaning that the problem you have is not related to Intel® HD Graphics but a Third party controller.
Due to the nature that your system is a hybrid graphics, your compute requires a special driver that contains very important changes and customization that will make your board work as it should.
From our side, you can try the latest driver for Intel® HD 3000 at this link:
