Windows 10: Screen flicker and brightness reset on cold boot with NVIDIA GPU – HP laptop, no iGPU

Hello, I’m facing a display issue that might involve driver and firmware interaction. ### System: - Windows 10 / 11 tested both - HP Omen 15 2018 - NVIDIA GTX 1070 Max-Q - Intel iGPU disabled in BIOS not accessible - 1080p 120Hz panel ### Problem: When using any NVIDIA driver newer than version 528.92, cold booting the laptop causes the screen to: - Freeze during the Windows logo animation - Go black - Reappear at 100% brightness - Then proceed to desktop Warm boot and sleep/hibernate work fine. This seems to be a display initialization issue during cold boot in **dGPU-only** syste

Screen flickering in HP pavillion laptop

I have an HP Pavillion laptop but I have an issue regarding screen flickering from a few days ago. the display doesn't flicker at a certain brightness. if I change the brightness level screen start to flicker on battery mode if it is connected to the AC
power supply it doesn't flicker. I have tried many options like updating drivers and others it is not a window issue because I used dual-booted pc ubuntu and windows 10. On both the OS i faced the same problem. please give me a suggestion as i have frustrated
from the problem

 

Win10 older Nvidia GPU screen flicker

TLDR: My older HP laptop (Nvidia gpu and Win10) flickers no matter what driver and with both the 630M and 650M gpu. I installed gpu-z (techpowerup) and the flicker stopped as long as gpu-z is running. Why?

My older HP laptop dv6t flickers badly and constantly until the screen freezes. I have a dedicated gpu and the flicker only happens when the Nvidia gpu is enabled. This problem has been well known since 2014 when the Win10 upgrade first rolled out - the solution for most was to rollback to Win8 English Community-Lenovo Community (the flicker problem does not seem to have affected the AMD gpu). See here for a typical example Redirecting

The assumption back over the years 2014-17 has been that the flicker will be resolved through the Nvidia driver update https://forums.geforce.com/default/topic/859279/windows-10-353-54-flickering-issues/ I tried numerous drivers from as far back as 2014 and up to the release earlier this month (fairly certain I installed the drivers correctly). There are some posts that say installing Win8 and then updating to Win10 and then rolling back the Nvidia drivers solves the flicker. I cannot find where I read this - but, I initially had upgraded to Win10 from Win8 (or 8.1) and never had a flicker problem. I bought a new SSD and did a fresh Win10 install and found the flicker.

After three years it looks like it is not a driver issue since it would have been fixed by now. Is it something incompatible between Win 10 and the older Nvidia gpu?

I had a 630M (2010 Fermi GF117) in my laptop and it flickered. I changed to a 650M (2012 Kepler GK107) motherboard and it flickers too. Does it affect the 2014 Maxwell (I searched and did not find much about Maxwell flicker but most people don't post their gpu architecture)? Presumably the 2016 Pascal is fine. It says here that Win10 supports Kepler and newer (maybe supports Fermi) https://forums.geforce.com/default/...windows-10-faq-and-driver-installation-tips-/ Which means the flicker problem should not be due to hardware. But, it must be somewhat hardware since the newer Pascal does not flicker.

I thought maybe the gpu was overheating due to some driver/os issue (it wasn't).

I also considered it could be an energy saving (rapid off/on created feedback) flicker issue; so I tried high performance settings. No luck.

To see what the temps are I installed gpu-z (techpowerup) and set the gpu-z to start on startup. The flicker stopped... At login it flickers like mad, but, as soon as the password is typed and enter pressed, it stops. It runs for days with zero flicker.

My intuition is that the gpu-z temp sampling keeps the gpu in a constant 'on' state and this stops the flicker (meaning it is win10 energy optimization related).

Please explain this like I am five.

 

Screen starts to flicker after logging in for a while

Hello

This is an entirely new issue. My screen starts to flicker after logging in/turning on computer for a while, and/or if I launch an app that uses my Nvidia card (my laptop has Optimus), I'm not exactly sure which of these two causes it. For the first while after a restart, the screen appears fine. The flickering appears on desktop background + internet browser as well, so I'm pretty sure it's not a program compatibility issue. The flickering is not severe (the type that looks like horizontal bars sliding up) but it's an annoyance.

Tried:

• Disabling Windows error reporting + problem reporting service in msconfig
• Restart computer
• Resetting Nvidia global settings to default in Nvidia control panel
• Checking for display drive updates in device manager (all up to date)
• Checking monitor refresh rate (60Hz, can't be changed)

Laptop I'm using:

• i7-4700MQ 2.4GHz
• 1900x1080
• Intel HD 4600 + Nvidia GT750M

Thanks for suggestions.
