Screen flicker

Helmut · Feb 21, 2025

Looks like a guest ghost image of part of the desktop.
Use a simple colour for your desktop, makes analysis easier.
I would remove any system mods you may have for things like Start Menu.

Run the usual SFC and DISM checks, guides are in the tutorials section.

Overall I would suspect some internal damage has occurred, that is up to you to look inside.

It does not look like a cable problem, but try a substitution.
Monitor drivers are merely colour profiles for the display panel, you do not need those at all.
Unlikely to be a iGPU driver problem, drivers would be taken care of by Windows updates.
Very unlikely to be age.

There is no way you will fix internal damage by messing with drivers or indeed any software.

The big unknown to others is what/extent of physical damage has been done to your PC by dropping it.

In my main PC (2nd system specs) I have a 19" TV connected via VGA cable. Once I had an issue when the text would not be clear, but appeared like "simmering" (I hope I use the correct word), that is the lines quickly moving left/right by a couple of pixels. It was not the VGA cable or a loose connection or the DP-to-VGA adaptor. It was due to bad timing by the graphics driver. Now, after several driver updates the issue is gone, I guess the timing is more precise. So I would try to update the drivers first. You appear to have customized drivers by the manufacturer, so you must visit the manufacturer's support site and download the latest graphics driver from there, not Intel. You can also try a different refresh rate, such as 75Hz instead of 60Hz, if your monitor can handle that. I have noticed sometimes that 59Hz rather than 60Hz is used, check yours and if it is 59Hz switch to 60Hz.

PS: Overheating can also mess with the graphics memory and show artifacts on screen. Blow any dust from the computer and the graphics card, especially from the cooling fans, with an air spray or air blower.

The GPU in integrated to the CPU, so it is very unlikely that it has been damaged when he dropped the computer. It would require to damage the CPU and the computer would not work at all. Monitor drivers are supposed to improve colors on the monitor, but you can calibrate the monitor yourself. Search for calibrate colors and start the wizard. It's a good idea to also calibrate ClearType after you improve the colors.

no monitors are a separate entry. i'm telling you to change the driver under display adapters from whatever it is (nvidia, etc) to microsoft basic display adapter for testing. this will tell you if its the driver or not.

monitor is just shown as generic non-pnp monitor

So its already set as windows default. microsoft basic display adapter

I must say something else I notice, wondows recommends me to 2048x1152 mode. But pressing menu button of monitor and going to info says itself its a 1920x1080 monitor.

Also when testing the 12 seconds or so on 2048x1152 it does seem to not flicker, but yesterday i was messing with it, and kept it, but the 2048x1152 just doesnt fit the screen, i couldnt get it to fit, and then after that, when going back to 1920x1080 its also didnt fit, and i was in hell trying to get it fit, and somehow without me knoiwing what i did the old 1920x1080 fit again, and now i don't dare to fool around with it anymore.

no. again, set DISPLAY ADAPTERS to microsoft basic display driver. monitors is irrelevant here.

I can only disable UHD graphics 630, but I see no way to set it to microsoft basic display adapter

i could also uninstall it, should i do that? as in uninstall device, i don't dare right now, before anybody here tells me that is safe

ah thanks, i just did it.

Screen still flickers though

dacrone · Feb 21, 2025

you need to reboot to make it take effect

ah just did, i have a weird screen now though, like a cinema with black above and under, i see no flicker yet though, but sometimes after restarting i dont have flicker, i will try it a while in this mode, see if it flickers again

dacrone · Feb 21, 2025

you probably have to go into settings > display and reset the resolution to the correct sizing now. but test that out for a while and see if it eliminates the flicker. if so, it is a driver issue

yeah only two resolutions i can choose now, so i stick with this for now.

7ender · Feb 21, 2025

well tried other resoultiuon and its worse, but i cannto change back somehow, now the menu is faded out where i cannt choose anymore.

Well I still see no screen flicker, i guess it was a driver problem, so what should I do now, keep using it with the microsoft basic driver, or try again with the intel drivers and somehow get that to work, I think one problem is that somehow acer wouldn't let me download latest intel update.

Shall I try clean install of 630 graphics drivers and see if that is possible and works?

..but obviously, use your intel installer instead of the nvidia referenced

"monitor is just shown as generic non-pnp monitor"
Nothing wrong with that, probably just because it is a VGA connection and not getting EDID info.
In that case you may need an *.INF file for the monitor which tells Windows the range of accepted inputs.
That maybe hard to find for old Monitor models. Get the specs at least.
VGA is now legacy.
Monitor cable quality matters using VGA as it is analogue.

5et the monitor to conservative standard settings like 1920 x 1080 @ 60 Hz or whatever.

Your Display Adapter driver version number is seen here:
Device Manager > Display adapter > Intel > Properties > Driver tab > the last 4 digits in Driver version: ????

Your PC has HDMI outputs so you can use other displays like TVs and see if they have the same problem.
If they don't then it is time to dump the old VGA monitor.

The current connections are HDMI and DisplayPort.

"The GPU in integrated to the CPU, so it is very unlikely that it has been damaged when he dropped the computer. It would require to damage the CPU and the computer would not work at all."

That is not the case as recent Intel iGPUs only have Digital outputs. To get VGA requires extra chips and circuitry on the MOBO, see the specs for that Intel CPU and iGPU.

thanks, DDU website said their software should be used when a clean install doesn't work, so I tried clean install through intel, for now it looks good, but flicker can always come later, if so, I will go DDU route. Is that ok?

dacrone · Feb 21, 2025

whatever works for you. the whole point of DDUing in safe mode is to 100% remove all graphics drivers (it will auto use microsoft basic after that) before installing a new one.

the problem seemed to be the driver, and not the monitor.
But still maybe I should buy a new monitor anyway, can't believe how long I done with this thing. when I look it up, its a monitor from 2009. (Acer V243hq)
