XPS 13 9350 QHD screen flickers and cannot upgrade video card drivers

Hi,

I just purchased XPS13 9350 and I have a problem with installing driver for the video card.

At the beginning, when I at first powered the laptop, there was a black screen after the DELL logo.

I did some tests then I figured out that the video driver is the problem.

I installed a fresh Windows 8.1 with generic video driver and it solved the black screen problem.

From this point, I tried to update the video card driver and again, the screen went to black.

I tried to use the below drivers which all ended with the same result - a black screen while installing the driver:

Official:

9350_Video_Driver_9NXMH_WN32_20.19.15.4390_A04

9350_Video_Driver_GGP7R_WN32_10.18.15.4281_A00

Beta:

Beta_15.40.23.64.4444

win64_154022.4424

win64_154014.4352

Any suggestion how to solve this issue? I am afraid that the generic video driver causes the flickering in my screen which is very annoying.

BTW: I updated the BIOS to the latest before trying the above video updates.

Thanks.
