Horizontal line across the monitor. It happened yesterday.

I have a HP ENVY 23-c1 10xt AiO (Lavaca3-SB)PCUS and there is a horizontal line across the monitor. It happened yesterday.

Hello again javajohn23,
I would like you to try the following steps:
Step 1. Turn off the computer, and then remove the power cord
Step 2. With the power cord disconnected, press and hold the power button for five seconds
Step 3. Reconnect the power cord, and then turn on the computer
If the above steps do not resolve it try the next set up steps:
Step 1. Restart your computer
Step 2. Repeatedly press the F10 key about once every second for five seconds after turning the computer on
Step 3. Wait five seconds
Step 4. Press the F5 key. This restores the default settings of the BIOS
Step 5. Press the Enter key. This accepts the changes
Step 6. Press the F10 key. This opens the Save and Exit window
Step 7. Press the Enter key. This saves the changes, exits the BIOS, and then the computer restarts
Step 8. Restart the computer.
Another thing I can think to try is review the HP Support document: Changing Display Settings, Background Image, Icons, and Screen Saver (Windows 7) to see if you can identify anything out of place.
We can also try to reload the Intel Graphics Driver for your computer as it will wipe out the settings when the new driver is reinstalled.
Please re-post with the results of these steps. Thank you for posting on the HP Forums. Have a great day!

I have a horizontal line across the bottom of my screen how do I remove it?

Re: Macbook Air mid 2011, I have a horizontal line across the bottom of my screen, it appeared when I was updating my iPhone, How can I remove this line from my display?

It may be a GPU or display issue. In both cases, make a backup of your Mac and take it to an Apple Store or reseller to get it repaired.
To check whether it is a GPU or display issue, try taking a screenshot by pressing Command, Shift and 3 keys. The screenshot will appear in the Desktop, so open it and check if the line appears in the screenshot too. If so, it is a GPU issue; if not, it is a display issue.

What would cause a slim horizontal line across the screen of my iMac?

There is a slim line across the Center if the screen. It is horizontal. It does not appear every time I boot up, but it is causing concern.

Welcome to Apple Support Communities
It would mean that your display or GPU are starting to fail, most likely the GPU, as the line is not permanent. Does the line move during the time your iMac is turned on or change if you start up in safe mode (holding the Shift key while your Mac is starting)?
A good test you can do is to make a screenshot of the screen when your iMac is showing the line. To make the screenshot, press Command, Shift and 3 keys, and the screenshot will appear in the desktop. Double-click it and see if the line appears. If it appears, it's the GPU. If not, it's the display

My Classic developes two thin horizontal lines across the top third of the screen.

After a day using my classic in the car, I plugged it into its speaked dock and niticed two thin horizontal lines all the way across the top third of the screen.
Does anyone know how to get rid of them pleaase. Thx

You can try Resetting the iPod, won't work, if LCD screen is damaged or the display chip surface mounts has gone wobbly, which mean going in for servicing.
Otherwise.
Press Menu and Center button for 10 secs till the Apple logo comes on, then release the buttons.

Horizontal lines across the screen of my Vision:M, need he

I have had my player since Janauaryexcuse me, February and have not had a single issue until today. I turned it on, and there are thin, horizontal, white lines running across the screen. They seem to be most intense over the text at the top left hand corner and if there is any text or picture in the main portion of the screen. I have no idea what has caused and what, if anything, I can do to fix this. I haven't dropped it, had it near any magnetic or other electronic devices, left it in excessi've heat or cold or... anything. I've been babying this thing and now the screen is barely readable when on. Anyone know what's up with this Will I have to return this for repairs Message Edited by appetencexx on 09-26-200709:02 PM

I bought one on December 24th 2006, didnt drop it or abuse it, after 4 months the same thing happened, I was out of luck because the 3 month labour warranty was up.
I was told by creative to mail it to their office at my own expense blah blah blah. A quick google search informs me it is a common problem and creative pretends it's your fault the unit has become useless, people also had horrible experiences with creative tech support, so after spending upwards of $400 already to purchase the Vision M 60GB, I decided I wasted enough money and time with this company and I now use the unit as a fancy 60GB portable hard drive.

Flickering horizontal lines across the screen

My Toshiba LCD TV has a thin black line going across the screen. TV is just a year old and is not under warranty. I've seen some comments that the LCD panel needs replacing. Is this my only option? Any other thoughts? Thanks.

Our Toshiba Regza Cinemax TV has been acting up, it has shadowing, sometimes horizontal and vertical lines. They are worst on the left side of screen. Anyone know what part may need to be replaced. This has been doing this for quite a while, it comes and goes. Paid almost $3,000 for this piece of crap it should have lasted more than five years.

White horizontal lines across the bottom of Macbook display

Shortly after I turned on my Macbook last night, the bottom of the screen started to flicker and solid white lines appeared across the bottom of my screen. They go up roughly a couple inches from the bottom, and fade towards the right of the display.
When I restart my computer, They reappear as macosx is loading.
When I mouse over these white lines, the cursor is unaffected, yet they dont appear when I screenshot.
I've gone back through all the discussions but couldnt find any solutions =S
Ideas?

I think you may find hope with this article:

The effect is rare but not unknown. Unless it's a hardware issue, you might be able to use this fix.

Source Monitor has horizontal lines along the video

Hi,
In the source monitor [only after the video is rendered] I get these horizontal lines across the video. Looks like this http://yfrog.com/7bpremierproblemj
I was wondering if anyone knows how to fix this? Also, the rendered file is fine which really confuses me and if I click on the video in the source monitor then it is restored back to normal, until I click off it then it goes back to having those lines.
Thanks
PC specs:
Intel quad core Q8300 2.50ghz
4Gb RAM
ATI Radeon HD 9570

Thanks for correcting me there 'vertical line'.
I've recently installed new drivers and I still have that problem. Driver errors wouldn't explain why the video is fine when I import it. If my computer struggled to play the video then the exported file would have the vertical lines to, however it is fine.

Notebook dv7t. Red transparent horizontal lines across entire screen.

I need to know if it's as bad as I suspect. 2-1/2 yr old notebook dv7t on Win 7, with 17.2" monitor. No error messages. Troubleshooting finds nothing. Never had any problems before. All day yesterday, Tuesday 8/19, rebooting and shutting down repeatedly without success. Today, nothing, no lines!. Gotta expect it to happen again. No update available for NVidia GeForce card. Can anyone please advise? Thank you. Sillenn

Help!! My Zen V Plus has a black line across the disp

Hi can someone please help me, my v plus display has a horizontal line across the screen and it really ruins everything. Can this still be fixes? Would anyone know this problem or had the same experience?

I have had similar bugs. If your player is still in warranty, your best bet would be to contact the store of purchase or Creative, explain your problem and ask for a replacement.

Lines across the screen

I have noticed for the first time today (after I have been working on my iMac for a long time) that there are horizontal lines across the whole screen from the top to the bottom. First I thought they would only be on the picture of my desktop background, but then I opened iPhoto and saw the lines on every picture I opened. So those lines are there on the screen and and not only on the displayed image. Really annoying!!!
Unfortunately my iMac is not under guarantee anymore...

I have this too! I just bought this iMac a few months back. These screen are having a lot of troubles from what I am reading. My horizontal lines are not that bad, but you can notice them.
I might sell these computer off quick as apparently the quality of these screens is a nightmare.

Weird horizontal line across my macbook air 11"

It's been 2 days my Macbook Air 11" (bought on 2011) started to display an horizontal line across the screen. It gets dark when the background is light and it gets light when the bg is dark. I tried to get a screenshot but it doesn't show the line.
Do you have any idea of what it is? I bought this macbook while I lived in USA but now I'm back in Brazil. Any suggestions?
Thank you.

Glowfilter sometimes adds a line across the middle of the bitmap

I am using a glowfilter to draw the outline of a shape onto a bitmap. I set both inner and knockout to true.
Most of the time when I apply the filter, all goes well. But sometimes, some of the shapes end up with a horizontal line across the middle.
Does anyone have any idea what might cause this, and what workaround could be used to avoid it?

Horizontal Lines Across MBP Display

I am getting horizontal lines across the display of my laptop. The lines do not show-up when I have the computer attached to the external cinema display, and the lines will go away if I run the disk utility, with the only errors being SUID errors that cannot be repaired, and Apple has said aren't an issue. However, the next time I open my laptop, the lines re-appear. I've reset the PRAM, and that didn't work. If the lines are showing, a rebooting of the system does not help. The only fix I've found is running disk utility, but that is a very temporary fix.
The lines are all over the screen rotating up from top to bottom, and multi-colored. The overall display is blurry.
Any ideas?
Thanks,
Will

Unfortunately, that makes it sound like a problem with the built in display. Have you tried running the extended version of the Apple Hardware test? If you get an error code, it might give you a clue.
Do you have access to an Apple Store? I think they have a special diagnostic for the NVIDIA chip problem, so they might be able to pin down for certain if the problem is with the chip or the display.
Good luck!
