I upgraded my Dell Latitude E6510 with an Nvidia NVS 3100M to Windows 8 a short time ago, and noticed something fairly quickly: Whenever my display came back on after being powered off from power saving mode, or the laptop came out of sleep mode, the screen had a very noticeable flickering and some distinct horizontal lines. The best way to explain it was to say that there was something very wrong with the display refresh rate.
The effect would gradually diminish with time, but wouldn’t completely go away. I updated the graphics drivers from the built-in Windows 8 drivers to the latest ODE graphics driver for Windows 8 64-bit (310.90) — that didn’t fix it. I also noticed that putting the display in 40hz mode and then back in 60hz mode didn’t fix it either. I even would have the problem if I shut down completely and powered the laptop back on a few moments later.
I later found this blog post from someone having the exact same issue. He even indicated that he’s had hardware replaced on his notebook, and that didn’t fix the issue. He did, however, find a fix: Dell’s A08 drivers for the NVS 3100M graphics chipset. He posted links to a Dell search for A08 drivers and two drivers that specifically worked:
nVidia NVS 3100M – Win7/Vista 64-bit Graphics Driver (this is the one I used)
So I uninstalled my existing Nvidia drivers and installed the 64-bit driver linked to above. You know what? It worked. The flickering went away immediately, and it continues to work correctly resuming from standby.
I also recall speaking to someone who had a similar issue, albeit on Windows 7. I’m guessing it was probably related to the drivers as well.
UPDATE: After doing some more testing, I found this: I took a clean install of Windows 8 where the screen flickering was there, reformatted and reinstalled Windows 7 64-bit. After booting into Windows 7, the screen flickering was still there! It would seem that the driver is manipulating the graphics controller to produce this flicker. Installing Dell’s recommended NVS3100M driver for Windows 7 did fix the flickering issue.
