Flickering video issue.

Q: Flickering video issue.

Hello! :D

I've been seeing flickering video in Media Player Classic. It happens fairly frequently and occurs with Windows Media Player as well.
I've used both the latest build of Media Player Classic Home Cinema and the 1.60 version but the problem persists.

I also tried turning on "deinterlace" in the shaders but it didn't help.

Any ideas?

Preferred Solution: Flickering video issue.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Flickering video issue.

have you got all your codecs installed?
try KLite
are you playing high resolution video?
Maybe your computer is not powerful enough to play it and you need a graphics card or to turn the resolution down on the videos

Hi all,

System specs:
P4 2.8GHz
ASUS P4C800E Deluxe P-4 ATX Motherboard
Antec PLUS 1080AMG ATX Case w/ 430W PS

I just replaced my video card, which was an ATI 128MB Radeon 9800 Pro AGP, with an ATI Radeon X1600 Pro 512MB AGP. Since then, I am getting very random "flickering", or what appears to be screen flashing. Most often happens when opening apps or switching between apps.

I checked ATI support, and all that they suggest is updating the AGP BIOS drivers, which apparently involves updating the complete BIOS, something I'm not sure I'm comfortable doing, or is apes. I would have assumed that the AGP drivers were compatible with another ATI AGP product.

Could this new card be drawing enough additional power to be causing this anomaly? Any suggestions or ideas? Thanks!

We have run into a hard to solve problem in my office, we use Nvidia Quadro GPU's, and when we have dual LCD's connected to the systems, we get some random "flickerings" and troubles with moving objects to the second screen. Ie colors not returning, boxed "dissapearing" It seems to me like a buffer is out of sync, but Im not sure how to solve it, we have tried more current drivers, but nothing has really "solved" the issue. and people eyesight might be on the line here.

The systems are Dell Precision T7400's, with dual quad core CPU's.
The issue has been most prevalent on the Nvidia Quadro FX 570 cards.

I was wondering why my screen at times would occasionally flicker for no reason, I have the latest driver from HP's website:BIOS: F.09Intel HD 520: I've noticed that it triggers when I start flash videos, but I still suspect its a deffinate video driver issue more than flash causing it, nevertheless, it still randomly triggers even when not watching any flash videos, I also noticed that it also causes my audio to stutter due to its instability.Yet my screen would occasionally flicker.Thanks for your help!-Kevin P.

A problem just started for me out of the blue, When i view a video file in itunes (m4v format) the screen will flicker with black lines/blocks (not like pixelating) /and full black.

It just started yesterday but now does it with videos i've watched before that weren't having problems before.

i tried uninstall/reinstall itunes, and upgrading to newest version ( I'm running XP Home on an HP laptop, 1 gig ram, and a NVIDIA GeForce Go 7400, 512 MB.
Any ideas?

A:Solved: Flickering video.

I'd check to make sure your DirectX is up to date and your video card drivers are also. Sounds like drivers, but it could also be a DirectX issue. Also, some older monitors connected with VGA, can sometimes have signal issues if the refresh rate or colour definition is too high for the monitor. If you're connected using HDMI or DVI then don't worry, and it's most likely drivers, or it could even be the game. Check for any updates on the game. If it's a software issue, Microsoft should know about it and have a downloadable fix.

I have an htpc that i built about 5 month ago with the following components

Gigabyte GA-M57SLI-S4
AMD 6000 athlon x2
4gb ram
ATI 2600 PRO
Vista Ultimate OS

Im connecting to a 46" plasma via hdmi.

Everything worked fine for months but in the last week i have noticed a slight stutter in all mkv files, blu-rays, no matter what video format or player i use.

If i resize the player screen so i can see the video and my desktop i can see what looks like flickering and this seems to cause the video to stutter.

This only appears when playing videos, cant see it any other time

I dont know the best way to explain it.

I have tried numerous drivers for the gpu, this has not helped, i have also reinstalled vista on two different hard drives with the same result.

With a fresh install of the os all i installed were the codecs needed and still the problem is there.

I have tried a different gpu with the same problems.

I have also tried with only 1 stick of ram and its the same.

Is there a chance that it could be the motherboard.

Any help would be great.

Finally got (don't laugh..kids love it) Kellogs Mission Nutrition to load on XP using compatibility settings BUT..when the game kicks off the screen is all flickering horizontal lines.. if the Tiger jumps, you can see a shadow where the graphics move...totally unplayable.

Is it the refresh rate I need to change?? I have updated the Video driver (Nvidia Geforce Mx440) updated everything else I can think of (directx 9 etc) but no joy. My monitor is a Samsung 152v if that helps!
I'm having a heap of problems getting ANY older games to play even with the compatibilty mode ....


A:video flickering madly on XP

I'm guessing that this is an old game.... so mabye it would help if you change your desktop resolution to something low, and the refresh rate to low before you start to play? It might help....but it's tough getting older games to work on XP.

Hello, I have a Samsung SyncMaster 204B LCD monitor that is flickering after being turned on from being off for more than half an hour or so.The screen appears to be very dull and flickers a bit for about a minute or two,until it "warms up" then the screen brightness and clarity becomes normal,and the flickering stops.It seems to work normally when left on indefinitely.

Is this an early sign of failure? Repairable at all? It's close to 4 years old.I paid $500 for it at the time (right before LCD prices dropped significantly ) so I'd like to get at least a couple more years out of it.

Any suggestions? Thanks for reading.

My laptop has had occasional problems with black flickering from day one, but now it's a pretty constant occurrence. I've done all the driver-type things but I really think it's a hardware issue, as slightly adjusting the screen often "fixes" the problem, at least for a while, and the flickering is never shown on duplicated screens. Here's mine: https://www.youtube.com/watch?v=w5sxB4GO6uo  I love this laptop when it works. But seeing the hundreds and hundreds of other similar comments and videos online is making me very frustrated. Why hasn't Lenovo acknowledged this as a hardware problem? Why are so many people sending their laptop in for repairs, Lenovo keeping the laptop for a month or more, then sending back an equally faulty unit? This is my work laptop so I can't just lose it for a month anyway. It just seems so unethical for Lenovo not to issue a recall on this product or refund people who have purchased them. Has anyone found a successful workaround yet? There are lots of videos of people taking their laptops apart and having some luck with tightening screws and so forth, but even some of those posts have comments later that it only worked for a little while...

Hi All,

I'm trying to fix a flickering screen. I am pretty sure that it is a software related problem. It happened after I formatted and re installed XP professional. The reason I believe its a software issue is that it is not a constant problem. A lot of time it will be flickering and then you open up IE explorer and it immediatly stops. Then when you search something it will come back. It also sometimes happens during start-up so not sure if that means something. I have updated the BIOS based on Compaq website and updated all drivers. I should have mentioned I am talking about a Compaq Presario 2200 Notebook.

The flickering is horizontal lined where if fades dark and light. Sometimes its the entire screen other times its just near the top. Moving the position up and down has no effect on the flickering. (Another reason to think its software related). Also I don't have an external monitor to hook up to and see if it is hardware related unfortunatly.

If there is any questions I would be happy to help and any suggestions would be greatly appreciated!!!

Thanks in advance.

Its this crazy flickering that keeps happening after playing games for a period. But when it happens in games like Skyrim, it does it in EVERY game then and windows explorer. Nothing else though. It only occurs in games like Skyrim, Tropico 5, Company of Heroes 2, Payday 2. Shadows of Mordor is another one. I have to restart my PC to get it to go away. But it comes back eventually, it usually takes like 30+ minutes to occur. Here's a gif: http://gyazo.com/8619db54132a8357122948e0bb27fed9 NOTE: It has never happened in the game on display, like I have that game at max settings and I can play it for 5 hours straight and it won't happen. ALSO, this is a VERY recent problem. I've clocked 50+ hours in Skyrim AND Payday 2 before this ever happened. One last thing, I have tried hooking up to another monitor, it occurs on that monitor as well so its not my monitor. I've tried a different DVI cable as well. I tried a fresh clean install of a new graphics driver. Specs: http://gyazo.com/2cf8050d81f429286ecf63f4e1739c26 http://gyazo.com/8560ee5315aff162dea8751e7d2c6efa

Hello everyone.As the title says, my laptop's screen flickers. Let me say a few things i have tried.- I have already rolled back and downloaded again my intel's graphic card drivers. - I have done the same for the Nvidia graphics card but not just roll back but a complete removal.- I have pushed back and forth my screen slowly (nothing happened) The thing is, i have noticed that the screen flickers mostly when i switch on my laptop and not while it's working. Moreover, when i rolled back into previous drivers (intel's), by the time the procedure ended, the screen went into a rage and started flickering a lot, turning red and blinking and after a while it stopped. Here's a small video while i was working on the laptop --> https://youtu.be/l25SyC-c8gU I know that there is already a post about it but i though of creating a new one once i had a video included.P.S : The laptop is 5 months old.

I'm looking for some help diagnosing a flickering screen problem I have with a Sony Vaio laptop. So, it's started happening recently when I turn it on, it flickers as it turns on, then eventually goes all black. Sometimes if I close the screen down it comes back on again for a few seconds. When I re-boot again it always has the same behaviour, flickers and then eventually goes black at some stage, not always at the same stage, sometimes I might get to log on, sometimes not. I've connected to an external monitor and everything works fine.

For me, it's not an inverter issue because I've seen inverter issues before and it was very consistent behaviour, the screen just blacks out consistently and you can see the screen with a torch, in this case, I can't really see screen with or it's very difficult to. If it is ccfl issue, I would've thought that bulb would be gone and that's it, it would just never light up....

One more thing that would indicate ccfl issue to me is if I turn it on and have the screen dimmed to it's lowest it works fine and stays on until I start to brighten it up again and then just goes black.

Any experts out there can diagnose this for me, I'm not sure if it is ccfl issue, and I don't want to go messing with it, I tried to replace a bulb once before and it was a disaster, not an easy process for a half amateur compared to replacing an inverter.

One other point is that there seems to be a... Read more

Hi, I just bought the Dell Inspiron 2in1 couple of months back and started having the problem of waving / flickering of screen. This flickering is more towards right side of screen and starts from there, but with time moves on to the whole screen. After restart it disappears for some time.
                         When I checked the graphics setting, the refresh rate is set at 60 pHz by default. When I changed the refresh rate to only other option of 48 pHz, problem is gone for now. Can some suggest what could be the problem, whether it is a software issue or hardware problem. What is the possible fix ? Thanks

First of all hello from a new user, I have a problem with my computer but I need help to nail it down to one part (I think it's the graphics card, but who am I to tell).
A friend of mine said people over here are very nice and competent so why not try to get help here.

Long story short, I played a game, Velvet Assassin, that is rather buggy (I.e. it didn't let me change the resolution to my native 1680x1050).
After some time the screen started flickering in complete white with some color bars here and there. I thought it was another bug on newer systems and changed the resolution; the problem seemed resolved.

Until my little brother started to play Forge of Empires, that little browser game, where the problem again occured at an even faster rate.

I hope you can help me, I made a short video of the issue, I know it's not of best quality, but maybe it helps.
Thank you in advance

Bumped into this tftcentral.co.uk article by accident. It pretty much explains the intermittent flickering I noticed in my XPS 15 9550. DELL support could not figure that out themselves.
The temp solution was then to go to my driver colour settings and decrease the contrast and the brightness. Hopefully I will not need to change the settings again.

Hello, guys, as you can see in the print screens I attached, sometimes it's impossible to read anything on my screen, so forgive me if I post this on the wrong forum.

Starting this afternoon I started having a weird display issue. I'm using Windows 7 64-bit (latest SP) on Bootcamp in a Macbook Pro 13' (model 2011). Now almost always the screen is rendered illegible by some weird pixelated noise and flickering, with parts of the screen content missing (see pictures attached). As I move the mouse/type on the keyboard, sometimes the text/icon/image/whatever I'm trying to visualize appears again, sometimes not. I wasn't using the latest Nvidia drivers when it started (was ignoring the Nvidia Experience message saying that updates were available). So I thought it was a problem of outdated drivers. I updated the drivers, rebooted the system and the problem persists. When I boot the system on Mac OS, the screen is fine.

I wonder if this is some kind of virus/malware. i ran an AVG scan but it said my system was clean. Thank you very much for your help.

Hi everybody, I'm posting today because my HP 2159m monitor is flickering when I connect it via hdmi to my laptop.

I can hear the sound in the background and its smoth like the dvd is still playing however the screen still shows the first frame flickering rapidly like its stuck or like a cd skipping. Any help on what might be causing this will be appreciated. It only does does when i switch the input to the connectors. It works fine in TV mode.

I have a classical "flickering" display problem on my Dell C840 laptop. Since I cannot understand if the problem is relate to the lcd or to the inverter or to che graphic adapter, I am asking here for advice.

These are the syntoms:
the lcd flickers and shows random patterns
it gets worse as time goes by (if the pc is cold it happens after 20mins, if it's warm it happens immediatley)
it gets worse or better if I twist the base unit
it gets worse or better if I lightly push or pull the lcd (see here http://www.youtube.com/v/AbHDsUnY5PA )
as the patterns on the screen get worse, at a certain point WinXP freezes and reboots
I get the same problem if I connect an external monitor
I get the same problem if I connect to the laptop via VNC or LOGMEIN (remote desktop). (I think this excludes the lcd and inverter, since it means that the corrupted patterns are sent via tcp/ip to a remote controlling machine....
I tried with no success to change operating system, to work disconnecting all the disconnectable hardware, to change RAM dimms, to remove all pieces and to assemble back, even to change the whole motherboard.
I suspect a video card fault (I think onboard video memory broken).

we have a batch of new 5040's
I have had SEVERAL users complain about flickering/blanking monitors-- the one I am looking at now--both monitors will blank out and return.  it was doing it probably every minute. 
unplugging one or other monitor does not fix it.  will still blank existing monitor
no real commonality other than 5040's
bios / drivers are up to date
originally on a dell 19" on DVI (DP-DVI cable)-- blanked/flashed
new monitor--24" dell on DP (DP to DP)-- still does it
I am beginning to think there is a big problem with these display ports on the 5040's
also note that these users have two or three monitors each.
This is becoming a real thorn.


A:OptiPlex 5040 SFF video is flickering/ blanking

I'm seeing this this precise problem with Optiplex 5040 systems with HDMI and 2xDisplayPort connections on board. I'm using Acer monitors, very inexpensive no-frills model V246HQL; not sure that matters.
Symptom: system works OK with a single monitor, via HDMI or DisplayPort to HDMI. System will not cold boot with 2 monitors connected if the monitors are HDMI and powered on. Turning one monitor off lets the system boot OK. Switching to a DisplayPort to VGA adapter works around it; and using an HDMI/DVI adapter plug also works around it.
Notable: this was after BIOS upgrade to 1.5.7, and 1.5.9. This was working on BIOS 1.2.7... I should have left it.
Onboard ePSA diagnostics will hang at "Video Card" test if 2 monitors are connected.
My workaround: use DisplayPort to VGA adapters, and connect 2 monitors via VGA.
A motherboard swap fixed this on one system. I'm about to have the second system repaired too under warranty.
I think this might have something to do with HDMI and DisplayPort display handshaking. I'm betting a future BIOS update might finally resolve it.

I bought an Hp notebook AU003TX..Second day of purchase I found my notebook's screen flickering and it was uncertain,it occurs may be one time or two times a day. Called the tech support no they told me to ON it in BIOS mode and it. was flickering in BIOS mode also so they said it's an hardware prblm we will send an engineer.Engineer arrived and in first half hr he said there is no prblm bt after some time flickering occurred and he said there may be some problem.I demanded DOA BT they denied and said there is no hardware issue drivers has to be updated so I got it replaced from my dealer and the previous notebook when checked drivers were already updated.Now after 4-5days again the same issue was found in my new notebook.Now service people says window or drivers has to be updated and these are already updated.They took the notebook and after two days returned saying there is no issue however the tech support says there is hardware problem as screen is flickering even in BIOS mode. The case has been closed and the problem is not solved yet.

I still can't use my touchpad.  I've tried driver updates, checked f6 but still nothing.  Due to the limited number of usb ports I need the touch pad to work.  Even when the touchpad is not turned off (f6) there is no synaptics drives listed in device manager.  Even when I run Lenovo's system check for upadate it does not identify that it is missing.  Also, from what I can tell there isn't even a serivce listed in Computer Management for the touchpad / synaptics. Please provide me with a solution as quickly as possible.  Thank you.  Peter D

hi, Today when i turned on my computer everything was fine. I used it for a short while and proceeded to put it in standby mode for about 1 hour or so, when i woke it from standby i immediately noticed that in the top right and bottom left corner the screen is flickering [as though i have set the refresh rate lower, but i have checked and it was not changed from 85hz] I am prone to migrains so i absolutely have to have the refresh rate set as high as possible to use my computer and it was never been a problem. The weird thing is that sometimes it stops flickering and goes back to normal, but that doesn't last long. I'm completely at a loss as to what is causing it as i didn't change anything between yesterday and today. I tried reinstalling my gpu driver with no luck, i've checked the cords and they are all plugged in correctly. My computer is by no means showing any different behaviour it runs just as good as always just this flickering. unfortunately i do not have another monitor so if anyone has any idea what this may be i would be very grateful. - Could it possibly be that the power cable from my monitor to plug socket is dying? It almost appears more as the corner of the screen is shaking slightly.

-UPDATE. My mothers room is right next to mine and i happened to go into her room and notice she had a heater directly on the wall separating our rooms so i turned it off [while the flickering was happening] and i moved it and so far i haven't experienced the flickering bu... Read more

A:Help Needed ASAP[Flickering Monitor issue.]

Hello and welcome to the forums!!! Who are the manufactures of your monitor and your graphics card?

Back in October I started noticing flickering green pixels on dark backgrounds on my screen, the flickering green pixels, when they are present are always in the same place.

The first thing I did was buy a new DVI cable and then I ran it from the monitor to a different DVI port in back of the GPU. The issue seemed fixed but then a day later the intermittent green pixels came back, at that point I totally uninstalled the newer Nvidia drivers I had recently installed using DDU and installed the drivers I never had issues with which were from early 2014. After I did that the problem seemed gone and everything was fine until last month when I replaced my mouse. I noticed my mouse pointer had three black dots following behind it in a horizontal pattern. I then removed the Nvidia drivers from early 2014 and installed the most current Nvidia drivers, I believe they're from the 14th of December. After I did this the three black dots following behind the mouse pointer vanished but a week or two later, the intermittent green pixels came back.

1. The intermittent green pixels do not show up in screenshots, I've taken numerous screenshots of the screen when they are present but in the screenshots they are nowhere to be seen.

2. They're showing up more often lately.

3. They don't seem to show up when if I set the display to a lower resolution or when I'm in the bios screen.

4. The GPU is a Nvidia 450 GTS and it is not overclocked and is usually running at 29c, the fan is runni... Read more

A:Flickering Green Pixel Issue = Monitor Or GPU

Hello and welcome Deviancy now my first thought was the monitor may be going south but in view of the changes around you swapping cables and drivers and the fact that the card is five years old now makes me wonder if the card is going south.

Have you access to another monitor to see if the same thing happens?

Second it may as well to test that card with this FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net now this can put a fair bit of stress on the card so best run when you are nearby to check things like temps etc.
