Screen Has Black bars (Malware?)

When I turn on my iMac the apple logo appears behind what looks like jail bars then a dark shade rolls down the screen then tiny squares appear all over screen with error message to restart if it fails to restart manually, which it does. Cannot get past this point. Any suggestions. Tried command R to no avail.

Try a Safe Boot (restart holding down the shift key until the grey progress bar appears).
Hopefully it will Safe Boot and allow you to copy the contents of the panic log and post it on here, where someone may be able to offer some tips as to what could be causing the KP. The log should be located here: /Library/Logs/DiagnosticReports
Once you've done this try restarting as normal from the Apple menu.

Edit: Have you installed any new software/plug-ins/add-ons recently?

Yeah it's dead. Take it to an Apple Genius Bar and have it checked out. Then buy a new one.

Widescreen has black bars top and bottom

Imported a widescreen DV file into FCP5, rendered it, looks widescreen in the canvas but has black bars which are always exported. But I want to end up with a DVD that is full screen/widescreen when viewed on a widescreen TV or LCD monitor. How to get that and get rid of black bars?

In the menu bar: go to Final Cut Pro > Easy Setup. Choose DV-NTSC Anamorphic. Click OK.
Go to Sequence > Settings > Load Sequence Preset and click OK.
Right click your clip in the Browser and choose Item Properties > Format. Click next to Anamorphic in the clip column to place a checkmark. Click OK.

When I rotate my video clip so that is isn't viewed sideways, it has black bars on both sides and some of picture is missing. Can I rotate the image so it plays rightside up without the black bars? The image was taken by an iPhone. I am viewing it on PC

Just to recap, this is a collection of ports I have collected over time for people who needed this information when setting up the HP ePrint app so that they could view their email from within the app. I am certain other applications also need this information. Although lengthy, I could not find a more comprehensive place to retrieve this information. Feel free to post additional information, faulty information, or other related topics below as this is simply a collection of data and it would be practically impossible to test all of them. Thank you!

FaceTime has black bar on screen before call

When I launch FaceTime on my iPad 4 (retina), I get almost half the screen in portrait mode as a black bar. When I place the call, the screen is fine. This did not happen with iOS 7. Anyone got any ideas?

Thanks Bob for this, it has focused my efforts. It seems to be a bit 'random' to say the least, and my nearest Apple Store is a 100 mile round trip to get to. This is very much an iOS 8 issue, but it seems that dear old Yosemite has a problem as well which wasn't helping my diagnosis (no audio when call is initiated). I shall take my iPad in to my "local" store and see what the resident Geniuses make of it.
Once again, thanks for your input - as a developer it gets a bit lonely here, but when problems surface, it can become alarming!

Expand to full screen display- Black bars

I have an Apple Cinema display. I have black bars at the top and bottom of the screen.
I think it has to do with the aspect ration so the screen if filled.
I tried the System Prefs, but that didn't work.
I know it's an easy fix, but I don't recall how I did it before.
Something changed when I started up this morning.
Thanks,

Sorry for intruding in this thread. I just saw your question in the Aperture Forum.
Quick Previews On (Adjustment Disabled)
I've tried to Import photos that I took yesterday.
Each time I get the message when I try to tune up the new photos.
The message in a greyed out box is: Quick Preview On (Adjustment Disabled)
There has to be a setting that I've missed, but on every try, I get the message and can not post process my images.
Help !
Unfortunately, the moderators removed it before I could answer. You mentioned a new operating system version, that must not be named.
It is really simple: Quick Preview is a mode for quickly browsing, and it disables the Adjustments.
Click the button with the hurried looking rectangle to turn it off again:
Or simply press the keyboard shortcut "P" to toggle between Quick preview Mode and normal mode.

[X230] Screen issues (black bars)

Hi,
I've got a X230 with an IPS screen since 1,5 years, and I currently have some issues with it.
Sometimes, the bottom left of the screen blink and black bars appears, along with some square brightness shapes.
I'm pretty bad to description, so here an album of the problem : http://imgur.com/a/qIwj5#0 (it's more clear if you zoom).

This is a detail of the bottom left :

Again, this appear sometimes only, and a knock in the screen resolve the problem, but it's worrying.
Does someone has already have this kind of problems ?
Thanks for your responses !
(and sorry for my grammar, I'm french )

Solved!
Go to Solution.

Hi,
Connect the system to an external monitor and check if it displays correctly. If it does, probably your LCD panel/invertor/cable had gone faulty. If it comes out the same way on the external monitor, you're looking at motherboard repair/replacement.
Click here to open a link where you can select the country and get the exact contact support number. I’m sure they will be a great help.
Best regards,
Mithun.

Are you sure? my client wants to put these clips on a tv screen, and they keep showing the black bars when they play on their computer, I cant work out why it has them, why does it?
It doesn't matter what size your clip is. The video output is 720x480. If you place the small cip inside a standard video player, it will expand because the video player has to fill the output. Umm, that's not EXACTLY what's going on. The video feed cannot distinguish between big and little clips. it only knows to fill the screen with whatever it sees.

My iPhone 5 screen has blacked out.

Hi there,
My iPhone 5 screen has just randomly blacked out on me.
I sent a text message to someone then lay my phone down on the sofa and when I picked it up again moments later the screen did not work and it is completely unresponsive. When I ring my phone it rings but I cannot hear my ringtone. Plugging my phone into charge does nothing and I have also tried pressing the lock and home button at the same time for 10 seconds which also does not work.
Has anyone else had this problem?

Also forgot to mention that when I plug it into my MacBook it's also unresponsive with my iTunes

Hey wealthylives,
Welcome to the HP Forums!
As the computer screen is remaining black/blank after the hard reset, I would suggest the following document 'Troubleshooting Black Screen Displays with No Error Messages During Startup or Boot'. Please follow through the steps outlined in order.
Please let me know the outcome of the troubleshooting.
Thank you.

My screen has black as the backlight instead of light. I did the update shortly before this occurred.

MY screen has a black backdrop instead of light. Wonder where to change the setting. Not in the settings that I can find.

Hi Lisa,
Go into Settings>General>Accessibility and see if "White on Black" is turned on. If it is, turn it off. Also, check the "Triple-click the Home Button" setting to make sure that the "Toggle White and Black" is not turned on there.
Hope this helps!
Cheers,

Screen has black/dead pixels and line across screen.

My iphone is still under its one year warranty. I can not recall any drops or it ever being handled roughly, however I have a black/gray blob of dead pixels in the left corner and my screen has a shiny line that looks like a crack of the LCD, however the glass screen is not cracked in any way that I can tell. I think the dead pixels are spreading as well. Has this happened to anyone else? Does anyone know if this is under warranty? I live over an hour and a half from the nearest apple store so I really don't want to take a special trip to see a genius only to find out that I will have to pay $200 to get this fixed. Any help/advice would be greatly appreciated!

If it is still under warranty, they should replace the screen without charging you. The same thing happened to me a few months ago and they replaced it for free. You might have to make the long trip to the store but they shouldn't charge you and it will take about 30 minutes. Call to make an appointment first if you plan to go to the apple store.

Dual Monitor has black bar on left

I have a 27" iMac running OS X 10.6.5 and have my second monitor (AOC 20" monitor with resolution of 1600 x 900 @ 60Hz). There is a black bar on the left side, can I get rid of this?

I rechecked my AOC and it's actually 22" with 1920 x 1080 @ 60Hz, which is what I have me settings at.
