Eldeep1990 Posted February 7, 2016 Share Posted February 7, 2016 hi i have problem with my laptop screen (1920*1080) as it is flickering white pixels randomly when power on laptop from cold and this begin with bios boot and still existing until making sleep and wake up (after 2 or 3 min after startup and warming up) or close the lid and open it again (sleep). then it disappeared. I attached external monitor to laptop when the problem shows up but external monitor works fine.then i have another dell latitude E5520 with screen resolution (1366*768) i exchanged the screens and they works fine for 1 day without problems on both sides.what could cause this problem? Thanks in advance. Link to comment Share on other sites More sharing options...

Hi Jose_49 It is not related to video drivers as it starts from bios boot not from the beginning of windows startup. Link to comment Share on other sites More sharing options...

Is it persistent on the external monitor as well. If Yes, then it something related to the GPU Hardware since its starting from the BIOS Screen as well. Can you try to maximize the brightness and then reduce it for a time being? Also look for GPU Temperatures, if they are quite high then clear the air vents of the laptop.

I got this solved by disable optimus technology from the bios.so the display works directly now from the nvidia card.and tested it till now and it works fine. +Zlip792 1 Share Link to comment Share on other sites More sharing options...

Mando Posted February 9, 2016 Share Posted February 9, 2016 (edited) my Precision M6800 can be a bit like that with its AMD GPU, ive set switchable gfx to only use Intel igpu when running on battery. Issue then went away only happens when i fit it to the model specific dock, and never shows on any of my 4 external LEDs. All i need now is a Sherpa to carry it around for me, the thing weighs a ton!
