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.

Hey Dean Marvin,
Thanks for the question. These two symptoms are probablyh related. To troubleshoot, let's try resetting your iPod:

What model iMac? This forum covers three different variants made before 2006. They have different display technologies.
Doing "About this Mac" from your Apple menu and posting the info found there for your processor type is a good start. If that shows you have an Intel processor, those iMacs are different enough to have a separate forum here:

Hello Armando
Check out the article below for troubleshooting your issue with the display. There are a few things that can be done, like changing the resolution of the display and also to reset the NVRAM to see if that resolves that for you.

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.

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!

When doing the app exposé gesture, is it normal to see a thin white horizontal line at the bottom of the screen after minimizing a window?

I noticed that when I open two windoes (say Safari and Trash can) and minimize both windows so they go on the dock, when I do the swip down gesture with 3 fingers (App Expose´) there is a thin white horizontal line at the bottom of the screen. Does it happen to every macbook pro out there? Is this normal? Hope it's not a display screen problem...

You would have to have multiple pages of the app minimized.
This is what it looks like with Safari with 1 page open and 4 minimized.

Pictures taken with my 1D Mark IV show a blue horizontal line at the bottom from ISO 400 onwards.

Pictures taken with my 1D Mark IV show a blue horizontal line at the bottom from ISO 400 onwards. So far nobody has been able tot tell me the cause of this problem. The body is still quite new (15000 pics taken).

I agree that it looks like a column of photosites is not working. But... I'm curious as to why this would only happen at ISO 400 or above.
The sensor is covered with photosites -- they are monochrome. On top of the photosites is the "bayer mask". The mask is a checkboard pattern of red, green, and blue "lenses" which makes the photosite beneath only sensitive to that particular color. They are group in clusters of 4 photosites in a 2x2 matrix. Two of the four squares (in opposing corners) are green. One corner is red. One corner is blue. If you were to lose a column which happens to be along the red/green column (as opposed to the green/blue) then you'd lose red sensitive and half the green sensitivity in that column. The result would be that this column is flanked by two "working" columns which are full of green/blue photosites... hence the teal blue look.
I do not know if this will work for you, but oddly... you can actually sometimes "clear" stuck pixels (but usually this is an indvidiual stuck pixel... not a whole column of them) by putting the camera into manual sensor cleaning mode (and you may have to do this 2 or three times). While the normal point of the self-cleaning mode is to flip up the reflex mirror and open the shutter so that you can inspect and clean the sensor (really the front-most filter because you can't actually touch the real sensor), it also neutralizes the charge on the sensor (or so I've read). This charging and discharging of the sensor a few times can often get "stuck" pixels to start working again. BUT AGAIN... I've only ever seen this used on individual stuck pixels... never a whole row.

Is there another way to close apps other than deleting them from the multitask bar.....I have a small crack in the bottom of my screen and that part of the screen does not recognize the touch. :(

Is there another way to close apps other than deleting them from the multitask bar.....I have a small crack in the bottom of my screen and that part of the screen does not recognize the touch.

There's generally no reason to be closing them that way at all. The apps you see in the recents bar are just that, apps that you used recently. Most of them are doing absolutely nothing. The only apps that are really doing anything in the background are ones that play music and ones that are using location services. Just leave them be.
Best of luck.

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.
