Screen Flickering and colored stripes on startup

[MSThaheem]

Hae There, 

                    I'm an Engineer by profession, I am having issues with display as there continious flickering of screen light when brightness is kept lower about 0% to 25% and sometimes it also flickers at 50% brightness. Moreover recently it started to appear colored stripes on startup and sometimes colored linigs appear in midest of usage. The System has Intel's UHD 630 Graphics as well as Dedicated Nvidia Quadro P1000. The display is 4K dreamColor .

That's the problem I'm facing and thing is that I love this Machine so much that I can't sell it. So please guide me to some practicle solution, Thanks.

Note: I've tried all possible Tricks & solution available on googling but none has worked.

Welcome to HP support community.

If the issue persists on the BIOS page it is a hardware issue with the display.

If the issue does not persist on the BIOS page try updating the graphics, touchpad drivers and BIOS on the PC to the latest version.

Uninstall the graphics driver from device manager and install the latest version of BIOS,touchpad and graphics drivers on the PC using the HP support assistant.

Refer this article to know more information about using HP support assistant. Click Here

Also, Try running a system diagnostics test on the PC and check if the hardware components on the PC are functioning correctly.

1. Hold the power button for at least five seconds to turn off the computer.

2. Turn on the computer and immediately press Esc repeatedly, about once every second. When the menu appears, press the F2 key.

3. On the main menu, click System Tests.

4.The System Tests menu displays , then run extensive test.

I tried to Rollback the current driver but it was disabled, then I tried by uninstalling the display driver (intel uhd 630 ) and checked the delete box, but when I restarted the machine there was still this driver in display adapters on device manager, however the problem still persisted. Then I updated the driver which made situation even worse. Now the screen has too much of flickering please help me I'm in midst of a crucial task on this machine.

Thanks

BIOS has full brightness so it does not flicker and the Device Manager page & Task Manager Page flickers too.
