Horizontal line flicker

hello.
while this doesn't seem like a major issue, it might be cause for concern if aggravated: it looks as if there's a horizontal thick line that appears and disappears in a fraction of a second somewhere in the middle of the screen at random intervals. could happen once in a couple of hours, or a few times during the same period of time.
so i'd like to know if this is an isolated case or a known performance glitch with this display.
thanks!

Hi!
I had the same issue on my Macbook Pro... I brought it to an Apple reseller to see what's happennig, they told me that was a mother board problem; so I returned the laptop to Apple and my second one is perfect!

Horizontal line flicker on screen

Lately I have noticed sometimes that I will see a horizontal line will flicker on the screen and then go away. Like when you turn on a screen and its adjusting because you just turned it on. But its been on the whole time. What to do?

I've been seeing this for at least three or four months. I'm concerned because these things seem to get progressively worse, though at least until now I haven't noticed any increase in frequency or severity. Just as described above, a thin, grey looking, horizontal line will flash extremely briefly at a seemingly random vertical position on the screen. Sometimes it won't happen for a while, sometimes it will happen two or three times a day.
I can't say for sure because it happens infrequently and I haven't been paying attention to it lately, but I want to say the lines only appear when I'm on the low-power 9400M graphics card, rather than the 9600M GT.

Hi John,
I would take your machine into a Apple service center. Its highly likely a hardware issue. The most likely issue being the display has failed. If there is no external damage to the machines display they will replace the whole display under warranty for you.

Hp 2711x Monitor: Flickering red horizontal lines, dots, shapes

I'm not sure if I have two seperate problems or if they are the same problem. But lately my monitor has many red horizontal lines or red dots, or random red shapes on screen that flicker slightly. They only appear on parts of the screen that are dsplaying either black or any dark colors. Any part of the screen displaying white will have no lines at all. The problem will go away temporarily if I shut off the monitor for a while.
Also before it begins doing this, and during, the entire screen will go bank for about 1-2 seconds and then come back. It never gives an error message when it is blank. I run a dual monitor set up with my laptop display and the monitor and the lines only appear on the monitor, not the laptop display.
I have the most current drivers for the monitor installed.
The computer is a Clevo W110ER with i7 3630QM 2.4 Ghz and a 2 GB video card, running Windows 8.

Hi Blue07,
What is the model number of the monitor.
I worked on behalf of HP.

Any filters to help with horizontal line jitters on ntsc monitor

Hey Guys,
I am working on a project that has alot of office forms that appear on screen. The horizontal lines of the forms wiggle like crazy on the ntsc monitor. Is there any filters that can stop the jitters?
I am using FCP studio
Thanks

Hi:
You can try with the standard Flicker Filter and adding a very small Blur. You must find the exact recipe for your footage.
Hope that helps !

Horizontal Lines in Footage

Hi there,
I am having severe problems with a day's worth of footage shot on a client's camera (which I had very little time to prepare with).
As you can see in the video at the bottom of the post, there are dark horizontal lines that move from the bottom of the screen to the top. From researching this seems to have been caused by the frame rate/shutter speed combination in relation to the frequency of the lights. FYI It was shot at 24 frames a second with a 60s shutter (unfortunately there was no 48s shutter on this camera).
Please can anyone tell me if there is any way to rectify this footage seamlessly in AE or any other software? Re-shooting is not something I want to consider, so I would entertain using any software or plug-ins to rectify this.
Many thanks!

In many cases the digital anarchy plug in Flickr Free will do an amazing job on this problem. The cost of the plug-in is usually less than the cost of a reshoot.
Flicker Free: Deflicker Time Lapse, LED flicker, and Slow motion / High Frame Rate in HD and 4K for After Effects, Final…
as a sidenote, this should have been clearly visible in the viewfinder or LCD screen of the camera. It's something very experienced cinematographer would look for.

HP Scanjet 8300 Horizontal Lines when scanning 35mm at 2400 dpi

When I scan HP Scanjet 8300 35mm the horizontal lines at 2400 dpi .. please tell me how can I calibrate the scanner.. or how could I control the light of TMA .. anybody If know about any software regarding this please reply me at [email protected]

[mi] EQ overflowing. The server is probably stuck in an infinite loop.
Seems a little suspicious, though its kind of a generic error message. Lots and lots of google hits on that one.
Are you sure none of the libs or executables for xorg-* got damaged before the system called for an fsck? The power went out on me once and my hard drive "forgot" about 75% of my kernel modules, although it was a conventional hard drive and not an SSD.
try re-installing some packages:
pacman -S xorg xf86-video-ati ati-dri libgl
(any more anyone can think of?)
[edit]
Is your copy of that bootchart that blurry or is flicker messing with it? It looks like its been resized even at largest setting. I can hardly read it.

L655D-S5055 LCD horizontal line issue - possible motherboard or GPU failing??

Hello,
A few weeks ago a horizontal line running from the left edge to the right edge of the LCD about 2 1/4"
from the bottom of the LCD started to occur. The line shows up from the time the screen turns on
and remains in CMOS or the Win 7 desktop. I have replaced the LCD panel with a new OEM LCD
panel, this did not resolve the issue. I replaced the internal video cable, this did not resolve the issue.
Since the line occurs in the CMOS screen (DOS prompt screen) or in Win7, there is not video driver
issue I believe. I also updated the L655D BIOS to the latest v2.10 Nothing has resolved the issue.
Is this possibly a sign of a GPU issue at the motherboard level? I have noted that the space below the line does "flicker" or distort the image, but only below the line. The rest of the image on the screen stays without any problem. I have also attached the laptop to an external monitor which has no line like this or any issues with the display at all. Thus the reason I had originally concluded the LCD panel and internal
video cable.
Does anyone know if this is a known problem with specific motherboards with this model laptop, or GPUs?
Is there a replacement motherboard program for this laptop as this is certainly a quality issue that should
not be left for the enduser to replace the motherboard and be charged a high cost repair such as this!
I appreciate any guidance or advice on this issue. I have attached two pictures for reference of this problem.
One shows the line in a Command prompt screen, the other while in Win 7.
[Updated: 2-Apr-2013] based on further research and experience with other similar issues, I am beginning to think this is related to heat and the GPU impacted by poor quality soldering or some other issue of that nature. I have performed "reballing" with other products, but am not sure about whether this issue can be resolved or how to go about an effective "reball" for this product motherboard. A replacement, used motherboard is hard to find and if found are over $150USD. Again, it seems unfair to the consumer to have a laptop like this for 4 years and need to replace the motherboard or live with this issue until the unit fails completely.
Thank you in advance.

Horizontal lines on iphone5

Hi!
I'm extremely exciting to receive my first iphone - iphone5. But it turned out there some issues on the display.
Right at the center of the screen, occasionally there are few horizontal lines flashing, and the funny thing is, screen under the flashing horizontal lines becomes blurred and almost unreadable. But as I said, it happens occasionally, it just becomes normal minutes ago, while the last few hours, those lines are just exicitingly flashing like I was hours ago.
I read through the forum, it seems this issue happened in the past generations, anybody sees the same?
Have a nice weekend
Han

I have this, not everytime - maybe half.

I have called Apple to create an escalation. I have a hunch this is an issue with the App store rather than the phones. I am waiting to see before I go through all the hassle of replacing it, the phone is performing excellently otherwise. I have a mixture of numbers and letters in my password, seems to be triggered by flicking to numeric keyboard and then dissappears when flicking back to text keyboard.

What is the white horizontal line and red vertical line on my brand new ipad mini?

Bought a brand new ipad mini 2 for my sons Christmas, took it out the box and it was during the set up process, ie entering his iTunes and icloud account, a white horizontal line and a red vertical line appeared on the screen and is there all the time now. Have tried switching off and on and resetting, but it is still there. Any ideas??

Hi Tolmivooz,
So the lines didn't appear until you were into the setup?
Does the orientation of the lines change when you rotate the screen?
Thanks for trying the restart and reset. Please see if a restore helps.
Get help with the screen on your iPhone, iPad, or iPod touch - Apple Support
If you see lines, missing sections, discoloration, or poor image quality
Try to restart your device. If you can't restart, reset your device.
If restarting or resetting doesn’t fix the issue, restore your device.
If you still see the issue after you restore, contact Apple Support.

Subtle horizontal lines in HDV footage exported from iMovie 06

Hello!
I just bought a Cannon HV-30, which I'll be using to film an instructional DVD. I'm hoping to use iMovie 06 to edit, and was planning on using iDVD until I realized how tricky DVD authoring is, if you want to sell thousands of copies of your DVD and have any hope of them playing on people's DVD players.
At any rate, I still want to be able to burn drafts of my film using iDVD. I tried doing this yesterday, but my footage was distorted both in the iDVD preview, and in the DVD I burned. The distortion looked different depending on how big the preview window was. When it was fairly small, I'd get this wavy, ripply effect whenever the camera panned. When I maximized the window, and also in the DVD (which was full-screen), I'd get a more subtle jagged edge to vertical lines--every-other-line on the monitor would stick out, like a fine-toothed comb. When there wasn't movement in the film, things looked pretty good, except for a bit of horizontal-lines visible.
I made my first DVD by using the Export... iDVD function. After I read on this forum that this doesn't produce the best quality, I tried importing the iMovie project into iDVD, but I got similar results.
Any ideas?
Thanks a ton,
Rob

DVDs look best on the system they were designed for: CRT TV sets with 640x480 square pixels NTSC (768x576 square pixels PAL)
When 'blownup' in size on large computer monitors or large HD TV sets the image quality will be less than optimum - that's why the new Blu-ray were created.
There are steps you can take when shooting your video that will help. Remember that mpg compression works on the differences between frames and anything that creates unnecessary difference between frames will cause reduced mpg compressed quality. So: use a tripod to avoid camera shake; make all your pans slow and smooth; and shoot with plenty of light to avoid the 'grain' caused by electronic noise in low light situations.

TV-out (Mini-VGA to S-Video) Horizontal Lines problem

Imac Intel Core Duo running 10.5.8 2ghz
i want to watch movie files on my tv. i bought a mini vga-to-video adapter from Apple. However, whenever i hook it up to my Tv, i get these rolling horizontal lines on the TV screen. i have tried every resolution combination, unplugged all extraneous plugs from both the Tv and computer. All to no avail.
this *****- i used to watch movies just fine on my eMac. ..if anyone has any ideas on why i get these ghost lines they will be much appreciated. thanks!

The manual doesn't state that this will work. I recommend you contact MSI and ask. >>How to contact MSI.<<

Black horizontal lines on start up and doesn't load GUI

So here it goes
My Late '11 15inch Macbook Pro went bonanas today. When it starts up there all these black horizontal lines running across the screen jiggering jabbering everywhere and I see three apple logos (due to GPU glitch I am guessing) after loading everything goes white and my laptop heats up and battery dies within like half an hour. I was bummed but then like after restarting a bunch of times and recharging my laptop it starting up normal again! I was super happy, but then it experienced the same crash next time the battery died. So, this has been going on and off; I don't know whats going on but it seems fixable I just want to know how.

Probably by replacing the logic board. I suggest that you take the MBP to an Apple store genius bar for a FREE evaluation . Then you will be in a position to make an informed decision.
Ciao.

Not printing properly with horizontal lines

HP Officejet Pro 8500A
Not printing properly (Faded colors) with horizontal lines, printing excess pages with odd scripts. I suspect printer heads.
All color cartidges are full.
Printing can be direct from computer or by scanning from the printer. Either way, it has the same issues.
