Display flickers rapidly after wake

If I put my display to sleep, then wake it, the display more often than not flickers for a minute before it stops. By flicker I don't mean turns on then off rapidly,, I mean the image blurs then focuses.... That's the best I can describe it. It seems to go away after minute or so. Is this normal?

I forgot to add, it doesn't do this every time.

Display stay black after wake up

Hi,
I hope there is someone who could help me, I have Macbook 2011 Early running Yosemite 10.10.2 and I have problem with my display turning back on after the sleep mode.
When I open the lid my display stay's black but everything is actually working, I'm able to login but everything is still black. This only happens when I close the lid, if my macbook is still open in the sleep mode than is everything absolutely fine. I had also blue screen two times, any idea what it could be please ?
I have tried to completely reinstall Yosemite, reset PRAM and SMC but none of this worked.
Any advise please ? Is it something with the hardware ?
I pretty much desperate and out of ideas how to fix that.
I will be really happy for any advise.
Thank you !
Best Regards,
Michal

If you have not already, reset PRAM
http://support.apple.com/kb/HT1379
and if that does not help, reset SMC
http://support.apple.com/kb/HT3964
which is unplugging the iMac and reconnecting using a precise procedure. You should disconnect ALL cables when you do this. If you have been using power strip, connect the iMac's power cord directly to a wall power outlet for this test. Power up with nothing connected except for the power cord. Once startup completes, add just your keyboard/mouse. I don't know how often this problem occurred, but try running the iMac that way (before connecting any other peripheral devices) to see if you can get it to recur. If you cannot, add back your peripherals (one at a time if possible), and again see if you can get the problem to recur.

Blue Screen on MBA with Thunderbolt Display after wake-up

I'm running a MBA (summer 2012, OSX 10.8.3) with a Thunderbolt display.
Very often after wake-up, I have a blue screen on the built-in monitor while the external display shows the login-screen. The MBA is frozen and I have to enforce a restart.
Any ideas to resolve the problem much appreciated.

ARD works only across a network, not via Target Display Mode. Your MBA will need to be connected to and active on your local network to be able to take control of your MBA from your MBP. I'm not certain if you can take control of a Mac connected via Target Display Mode, though I do know that applications on the system keep running, so it may be possible.
Note, though, that you don't need ARD to accomplish this assuming it is possible. The screen sharing feature built into OS X allows you to control on Mac from another with no extra software required.
Regards.

MBP 15 bad display after wake up issue

Hi all
I hope you can help me. I've googled so much about vertical lines in display but no one seems to have my problem. If the computer sleeps (or power off) during some minutes, after wake up I get a screen fully filled with vertical lines of the same color, about one pixel width. I've reseted PRAM, SMC. Normally after another sleep-wake up the screen gets fine. Any suggestions?
Thank you very much

Try resetting your SMC and PRAM.

Screen problem after wake up from sleep

About three weeks ago I posted a problem with the display coming back to life after waking up from sleep. I said this happened after the 10.5.2 update. This turned out to be not quite accurate. I actually ran all the waiting updates, so I really don't know which one to finger.
Today, I again ran the 10.5.2 update by itself. Everything is fine. Software Update then identified seven more updates to do, some familiar, some not. I have done all except one, one at a time, and have had no problems with the display coming on after the computer wakes up.
One more to go: Leopard Graphics Update. This is v1.0 for this update, and here is my question:
Before I run this update, and face another possible day-long re-install and re-update session, has anyone experienced the problem with the display remaining dark after running this update? I hate to do the update just to see if it causes the problem if there is some information kicking around about this.
Many thanks again for any help or comment.
Jim

Hi rohitgu,
Welcome to the Apple Support Communities!
I would suggest using the following article for troubleshooting the display flickering on your iMac. I would specifically Reset the system and Reset the resolution. I know you have done some good troubleshooting already. Have you reset the SMC as well as the PRAM? I also see that you checked the resolution on your computer, but have you started in Safe Mode and adjusted the resolution? Please use the following article as a reference.
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
I hope this helps,
-Joe

Cursor flickering rapidly on Equium A100-306

Having bought my new A100-306 laptop in December, I`m now having problems with the cursor flickering rapidly (and disappearing altogether when the mouse is not being moved) on certain 3D applications/games like The Sims 2 and Home Designer 3D.
I`ve downloaded the latest video driver for the intel 945GM graphics card, but there`s still no improvement. The problem is I can`t see where the mouse is unless I keep moving it and even then the rapid blinking is very annoying.
Would anyone know how to cure this problem please and if it`s a common problem with this model? As far as I can recall, we did have a week without trouble when we first loaded The Sims 2 originally.
Any help would be much appreciated!
Regards
Giles

Thanks for the quick response. I don`t get the same problem with Windows, word, and excel. I too had a thought that the grahics card could be struggling, but I`m sure we didn`t have a problme with the Sims 2 when we first loaded it. Unfortunatley I don`t recall loading anything either on the day that the problem first appeared. Will try altering the settign as you suggest.
On a connected point, though, I clicked on Media Centre yesterday (hadn`t used this until now) and had real problems with the cursor again during the intial set up - sometimes it was there, sometimes it had vanished and the only way I could get it back was to wait for the icons at the top of the set up screen to disappear (which they tended to do after about 10 seconds of being displayed) and then hit the touchpad. Sometimes I had to try this 2 or 3 times to get a cursor to appear and even then it was a struggle to complete the set up process.

Lenovo Ideapad U410: Display not working after sleep and/or restart

Hello all,
I am recently having some inconsistent display issues with my Lenovo U410 laptop i7 1TB with a Windows 8 PRO upgrade (came with windows 7).
When I press the Power Button on my laptop to put it to sleep, the Screen turns black as if it is off, but the Power & Battery LEDs on the front of the laptop remain on, as well as the LED on the power button. However, when I try to wake my laptop, there is no response on the screen (remaining black as if it is off). The internal fan is running, however I receive no feedback when "blindly" trying to input my password.
I've tried to turn the power off and back on to no avail. I've also removed the power source and held the power button for a couple of seconds and that did not solve the issue either. I've tried connecting the laptop to a screen via HDMI (since there is no other AV port on the device), but there was no signal being sent through.
This is an inconsistent issue that began yesterday 6/11/2013. When the laptop is left alone for a little and is turned on again, the display works, but after closing the lid (sleep) or pressing the button, the display fails to turn on upon awakening.
In most recent circumstances, Today (6/12/2013) I was installing a Windows update that required my computer to restart. When the update configured perfectly BEFORE it was restarting, but AFTER the restart, my internal fan began to work, but the display was not on.
Does anybody or Tech support know what may cause this inconsistent behavior? or know any solutions to this issue?

I am facing similar problem - post sleep & sometimes on touchpad event - the screen gets stuck & a strange array of gray screen comes or the existing screen's colors get distorted & the laptop gets stuck.
model - Lenovo U410; 64 Bit; Windows 7 Home basic;, Intel core i5 processor
I have upgraded display drivers but that hasn't changed anything. Any help is appreciated.

Display flickers on start up

My display flickers slowly when coming out of sleep or booting up. After a short while the monitor works perfectly. After it goes into sleep mode, or when the screen saver goes dark, upon awakening the flicker starts again. I recently replaced my ATI Radeon HD 5770 graphics card and VGA cable that connects to Mini Displayport / VGA adapter. Any idea what the problem might be and how to fix?

Converting Mini DisplayPort to VGA is fairly difficult.
If you are not using the larger DVI-I port, I suggest you buy a cheap adapter that pulls the Card-generated VGA directly off that -- no conversion required. The VGA signals are in the bar at the end and the four pins around it, plus one more pin from the top row of the grid. Salmon-pink in this diagram:

MacBook Pro Retina Mountain Lion + Dell U2713hm hangs after wake-up

This is a more specific description of my problems here:
https://discussions.apple.com/thread/4385171
I use a Dell U2713hm together with a MacBookPro Retina under Mountain Lion. The Dell is connected via the Thunderboldt to DVI-D adapter that is sold by apple. The Dell has a USB 3 Hub. The upstream is connected to the Apple-DVI adapter. I use a mouse and a Logitech keyboard, which are connected to the Dell USB hub.
The display blanks from time to time for some seconds, which is suboptimal and I would be greateful if this could be fixed. But the biggest problem is that the system hangs after wake up. Sometimes the external monitor just stays dark, sometimes I get the login screen, but cannot type since the swapping wheel is shown. I have to reboot the machine.
To me this looks like a USB(3) sync problem.
If there are any ways around this I would be really glad. Is there a way to disable USB3? I also noticed that the speed of components that is displayed in the system profiler depends on the ports I use for keyboard, mouse and camera ...
Thanks!

The solution is to dump the 100€ mini-display port DVI-D adapter that apple sells and buy a mini-Display to Display-Port cable for 6€. No crashes, no annoying interruption of the display (which I had several times the day for 2 or 3 seconds). There are very short interruptions now, but it is much better than with the apple adapter. The apple adapter needs a USB port, which is not necessary with the simple cable.
As for the monitor: Burn In, otherwise great. The burn in can be erased via monitor menu but should not be there in the first place.
Hope this helps.

PB G4 15" Display flickers then dies

Hello - I'm sure this has been covered before but the problem I'm having is the display flickers (after opening the PowerBook) then goes completely dim. I can still see the desktop functioning but just barely so I'm assuming that it's the display bulb.
I've been using an external display for a good time now and want my "lap" top back. Has anyone had experience replacing this bulb and/or just replacing the whole display? Which do you recommend?
I appreciate the feedback... thank you.

Yeah now that I look around a little more, PowerbookMedic agrees that it's likely the inverter. http://www.powerbookmedic.com/xcart1/product.php?productid=16612 Has anyone had experience with PowerbookMedic?
More importantly, can someone point me to an in-depth tutorial on replacing the Inverter yourself? Thanks

Mi iPod touch screen flickers constantly after iOS6 update

I have an iPod Touch 4th Gen and I recently downloaded the iOS6 update and tried to install it but after 12 hours of the black screen with the Apple logo and progress bar, I decided to just restore it because no progress seemed to have been made. After restoring it from my last back up which was earlier that day, it looked as if things were working fine but as soon as I unlocked my iPod, the screen started flickering rapidly between the normal screen and the updating screen that I was stuck with for 12 hours until it just took over completely and all I could see was the update screen. I tried pressing the home button and the lock button but it seemed to just be frozen. From what I could seen from the normal screen in the background, there was a message telling me that the update was complete.
After a while of no progress, I attempted to restore it several times in hopes of it working smoothly but it always ended up the same as before. I was thinking of just restoring it to default settings because the only thing that I really need are my few thousands of notes that I've kept over the past years because everything else has been stored on my computer and so thinking that they were backed up on iCloud, I logged into iCloud and saw that only a few were transferred.
Are there any suggestions as to what I could try?

Try:
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store.

Regarding to Display Flickering

Well, as a lot of people I'm one of those who have suffered the disturbing and scary display flickering. It was more frustrating since it begun after the 1st. year and I don't have AppleCare. Well I don't know if this solution works for everybody but at least for me it was magic. Before this I tried every hardware/firmware reset solution but nothing works. Also I have read of people who had their inverters replaced (for me it looks like a Logic Board replacement) and some with good results and others... well, not so good.
The think I did was simply erase the ~/Library/Preferences and never had those flickerings anymore. Maybe something gets corrupt there but by now I have a lot of days without even a little dim, perhaps in the Preferences is where the brightness setting file is located and it gets corrupt, I don't know but it worked, so maybe that's your solution too. Note: remember, if you delete the Preferences folder a lot of your preferences in the Finder, Dock, Dashboard and System Preferences will be back to factory defaults (or system defaults), but no personal or important files are deleted. The OSX in your next login/reboot will generate the folder again automatically.
Good Luck!

fredericlang:
I'm glad it worked for you!.
I deeply checked the Preferences folder and as I see the folder ByHost contains the screensaver and system preferences files and also other named HIToolbox but I don't know what is that for. I think the screensaver or system preferences are the ones who do the mess, so if this flicker comes again I'll try just deleting those to check.
Martin1301:
I mean ~/Library/Preferences
corband:
I think is just the CD that for some reason doesn't let the system to boot.
Just power up the macbook and with the chime sound press (and keep it pressed) the trackpad button until the CD is ejected.

Displaying a before & after in Elements 11?

How can I display a Before & after preview of a photo in work in Elements 11?
Viewing a before & after on the same screen would simplify editing as you can actually see any changes as you make them & if you don't get it the way you want then you could simply make any adjustments.

I think that comparing before and after side by side is more cumbersome and less effective than using the history panel or the layers panel to switch rapidly between two previous edit states. You can better use the display area to see details, and you'll detect subtle changes you could not tell side by side.
I think that comparing side by side is better suited to compare various styles of edits while seeing the whole images.
To do so, use the File/duplicate command. If you have set your preference to 'allow floating windows', you can set your windows as you like. The 'duplicate' is a copy in RAM, it is not saved on the disk unless you do it on purpose.
