Screen flickering in low light

Just wondering if any one is noticing the iPad screen flickering in low light?
I notice it mainly on a white page like apple.com nothing too major but enough to make me notice and wonder if it is just mine or a wide spread problem.

HI,
Try Resetting your iPad. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears.
If that doesn't help and it persists, take it back for a replacement. It should not do that regardless of ambient lighting.

Iphone 6 screen flickering dark and light

my iPhone 6 screen keeps flickering dark and light, whats happening and how can i fix it?

The symptoms you describe could be those of a battery being completely drained. When this happens the device will shut down and not respond even after attempting to charge. The usual cure is to plug the device into the wall charger and let it charge for at least 30 minutes. Then reset the device. Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot. If the device restarts let it continue to charge until the battery is 100%. If the device does not restart make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

Does all imac screen flickers at low brightness?

Hi, I just got the 21.5" imac.
I notice there's this minor flickering problem at low brightness, is this normal?
It seems like it's a known issue after I researched about it.
Is it a hardware problem or a software problem?
Should I exchange it?
Thanks for the help!

Welcome to Apple Discussions,
No that isn't normal, call AppleCare in the morning the number is in your owners manual.

Screen flickering in low brightness

Anyone experiencing this? If so, did you get it repaired?
I'm contemplating to go to Genius at my local apple store or calling the apple tech over the phone. What do you guys recommend I do?
P.S. I posted this under display forum, but there doesn't have as much as activities than here.

I see. But I don't experience the noise people are having with problematic display inverter.

T61 LCD display flickering with big patches of black and going to dark (very low light) afterwards

I have a T61 which has Intel graphic card. It is seven years old and at times has a noisy fan.
Very recently it started to have problem with its LCD, it starts with slight flickering of light intensity from corners of screen, here and there, eventually covering the whole screen, goes away and comes back, happens for few seconds, the pattern repeats for few times, then big (screen-wide) patches of back starts to cover the lower 1/4th, one-half, 3/4th of screen, flickering between the screen content and black screen, till they cover the whole screen after 30-60 seconds. At that moment, the screen is very dark but with a close look, it is still possible (but very hard) to read it. Connecting it to external monitor (through its VGA), it is working very well. Showing same screen on both LCD and external monitor at the same time, the picture on external is solid, but picture on LCD can have this issue. At the moment of writing this message, the problem seems to not happening!! but it was happening during the past whole week including few minutes ago. I searched online and here in the forum and read few posts, and found about these issues:
- some T61's have Nvidia GPU and thermal effects over the time and stress on the package or solder balls can make loose connections (this is probably not my case since the interface to graphic card is by Intel)
- problem with LCD itself (it is working fine just right now)
- problem with graphic card (it is working very well over the VGA to external monitor)
- problem with the ribbon from mother-board to LCD (tilted the screen in different angles when the black patches and flickering are happening and didn't change the chaos much in any direction of making it better or worse)
- problem with bulb inside the screen (maybe the cause, but somehow decided for the last few minutes to working fine)
- problem with inverter (don't know yet what this part it)
- problem with some sort of mechanical part(s) being loose, gently tapped on sides and back of the screen while the phenomena was happening and again didn't have much effect on it in any direction.
I appreciate your time and good gesture of help, many of you would know more scientific/engineering ways of approaching the problem and how to root cause it. My sincere thanks beforehand.

> the screen is very dark but with a close look, it is still possible (but very hard) to read it.
That sounds like a defective CCFL backlight or inverter.
>- problem with bulb inside the screen (maybe the cause, but somehow decided for the last few minutes to working fine)
A CCFL is essentially a high intensity fluorescent bulb. One failure mode is flickering.
>- problem with inverter (don't know yet what this part it)
The inverter is a power supply that converts the low voltage DC used in the rest of the ThinkPad to high voltage to drive the CCFL. I would expect that to fail catastrophically rather than cause flickering.
What to do?
CCFLs backlights are relatively inexpensive ($10 to $15 on eBay) but they can be difficult to replace because they're delicate. You may prefer to replace the entire LCD panel assembly or even the entire top cover assembly (which also includes the inverter card.)
The Hardware Maintenance Manual for the T61 provides detailed instructions for doing this sort of stuff if you'd like to see what's involved and decide what you feel comfortable doing.

Why is my iPod Touch 4G screen flickering light and dark?

my iPod Touch 4G screen flickering light and dark all the time?!?! I also have this problem where at the VERY bottom of the screen, Theres this white bar that keeps flickering on and off!! PLEASE HELP ASAP!!!

The screens are practically the same.
Did you purchase your iPod Touch second hand or direclty from the Apple Store? I would recommend that you go back to the Apple Store and show them both devices in action so that they can advise you closely.

Camera wont take a photo - warning "Low light" on screen

The camera and phone have been working fine*, until today when I get the error message on screen "low light" when trying to take a picture. It is being used in a room with normal lighting.
The warning only goes away when I point the camera directly at a light bulb.
The camera refuses to take a photo, regardless whether the warning is displayed or not.
Changing from auto <-> night mode has no effect either.
Any suggestions?
*Apart from a few weeks ago, the video zoom in/out stopped working, although it did take photos and videos ok.

HP Monitor L1710 -- power light flashes green when I turn on PC, screen flickers black w/ no image

Hello,
Last night I turned off my PC w/ a HP Monitor L1710, which I did not turn off. When I turned on my PC this morning the screen does not "turn on" -- the green light next to the power button flashes on and off, and the screen flickers between shades of black, like it's trying to turn of. This PC usually is not turned off at night (this is a work PC, and I just started to working at this desk (almost) never turned the PC off at night, so I wonder if it has something to do with that. I've turned the PC on and off multiple times, unplugged the power cable (for the monitor) and cable that runs from the monitor to the PC. I believe the PC is on (cd drive opens and closes, recognizes my phone when I plug it in to charge), so I don't think that is the problem.
I see a lot online that it may be stuck in power saving mode.
Any thoughts? Any help or ideas would be greatly appreciated

Hello @tom_degennaro,
Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I understand that your monitor is not coming on when you turn on your PC. I am setting out some steps for you to try for you to try below:
Step 1. Unplug the power cord from the monitor and the wall outlet
Step 2. Hold the power button down for one minute
Step 3. Plug the power cord back into the monitor and then the wall outlet (not a powerbar or surge protector)
Step 4. Press the Menu button on the front of the monitor
Step 5. Navigate to the Factory Reset option and select it.
If the issue still persists after the above steps try the monitor on another computer. If the monitor still does not work at that point then, it appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.
If however the monitor works on another computer you have an issue with the computer it was originally on. If the computer is an HP computer I would be happy to assist you with, but first I would encourage you to post your product number for the computer. I am linking an HP Support document below that will show you how to find your product number. As well, if you could indicate which operating system you are using. And whether your operating system is 32-bit or 64-bit as with this and the product number I can provide you with accurate information.
How Do I Find My Model Number or Product Number?
Which Windows operating system am I running?
Is the Windows Version on My Computer 32-bit or 64-bit?
Please re-post with the requested information and I would be happy to provide you with assistance. Thank you for posting on the HP Forums. Have a great day!

MSI R9 270X HAWK low GPU usage and screen flickering problem

I bought an MSI R9 270X HAWK vga and I have this screen flickering issue.
My S/N: 602-V303-02SB1310009419
I also had another problem: the GPU usage averages at 50-55% on every game (DX9,10,11 games like TESV Skyrim, League of Legends, Crysis 2-3, Battlefield 2-3, Far Cry 3) and never reaches more than 80%(well, once I made it run at 99%, I used ultra settings on Battlefield 4 with Sync on, Ultra preset settings with 200% res. scale so pretty much the maxed out Settings). I'm using this card with 8GB DDR3 Corsair Vengeance RAM with a stock clocked 1090T and AMD's reply for this problem was, that this problem can be driver problem as well as VBIOS.

I created a bootable usb, placed the files in it (formated, and only these files were at the usb, dos startup directed to win98boot's folder (C:\win98boot) renamed the tv303ms.134 to tv303ms.rom,l after i placed it on the usb and in the boot menu there are four additional options related to the USB (there's no USB only option): FDD, HDD, CDROM, zip. Selecting the FDD and CDROM starts the windows normally, The HDD option ended on the white-black screen, and there's where I can write: C:\>
after this i tried to type in: atiflash.exe TV303MS.rom [enter] nothing happened, then atiflash.exe [enter] and popped up some help instructions for the use of atiflash, I pressed enter over and over and then requested another command, I tiped in the tv303ms.rom [enter] and again nothing happened (invalid command I think). What should I do now ? I did some research but still can't figure out what the problem is. :/ (If I done everything correct, maybe the problem related to my motherboard or USB stick?)

24" iMac Silver - screen flickers

Just pulled it out of the box today. I can't operate at anything less than full brightness or the screen flickers. I can't find any other posts on this one. I see a lot of other related issues. Anyone having this issue? Did it go away?
I can't lose this machine to apple for repairs.

same for me, When I try and use the main system brightness control at the lower levels the display tends to have uneven strips that are lighter and darker.
its like if the monitor turns on and off very rapidly, like high speed blinks, i use an app called SHADE, it dims the monitor (dont now how) the screen dont flicker anymore and its free
http://www.charcoaldesign.co.uk/shades
Unlike other solutions, Shades doesn't change your display settings, and won't screw up your monitor's colour profile.
BY THE WAY, MAYBE ITS A PROBLEM RELATED TO THE FREEZING IMACS DUE TO THE ATI GPU
fine app, right price

5D Mark 3 Low Light Images = really slow!!!

Hello,
I've got a rather odd problem. When shooting in low light (think pitch black, lightning shots etc) the 5d mark iii takes forever to display the image on the preview screen. It takes up to a minute or more and I can see the red light (indicating the camera is busy writing?) flickering the whole time. Thinking this was a memory card issue, I switched over to the SD Card slot (I was shooting CF before) and encountered the same issue. I'm using San Disk Extreme (30MBPS) CF Card and Extreme (45MBPS) SD Card.
Are these cards not fast enough for what I'm doing? I'm shooting in RAW + JPEG, writing to only one card.
I thought it was a camera defect, but I talked to a friend of mine who had just bought his Mark iii and he had the same complaint.
Anyone else encountering this problem or did we just get a bad batch?
Any light you can shed on this issue would be greatly appreciated.
Solved!
Go to Solution.

I swore when I read this the second time I saw something about the screen flickering, not the read light. Seems I'm losing it.
I use the Lightroom noise tool for light noise reduction of everyday type photos. But if I'm doing something that needs a lot of work - HDR, photochopping, or just really high ISO, I use Imagenomics Noiseware. It can be a bit heavy, but I usually just feather in a NR layer overtop of my normal image(s) accordingly. It does really well on low key images, getting a uniform Black.

MacBook Pro 2011 - 15" Core i7 - SSD - Heating, Screen Flickering Issues

Hello,
I recently brought MacBook Pro 2011 15" Anti-glare High Resolution with Core i7 2.2 G Hz, SSD, 8GB of RAM. I installed Microsoft Office and Angry Birds at this time. I'm facing multiple issues with my first Mac. Is anyone facing these kinds of issues in new MacBook Pro 15" models?
Issue 1: Heating: Fan running on high speed even though room temp is below 60F. No major applications are running at that time expect Office 2011 and web surfing (NOT watching any video) and listening iTunes.
Issue 2: When I log-off from computer, the screen flickers and goes to lower resolution. Also the windows colors changed to different colors. After log-in, I went to System Preferences > Displays. The highest resolution is already selected (1680 x 1050) When I try to change to lower, it changes but still displays different window colors and changing suddenly.
Troubleshooting Steps:
1.) Shutdown and Disconnected Power Cable (at that time battery is at 65%)
2.) Reconnected Power Cable and Power On the system
3.) Display shows correctly.
Unable to Resolve:
1.) Still fan is running on higher speed at low temp (below 60F with no major application running)
2.) Sometimes Display is not showing properly. It shows different color shades.
I scheduled support call with Apple Support and let's see what Apple can do...

I brought my first MacBook Pro 2011 on Day 1, so I can't return it since it won't come under 14 day return policy. I'm taking my Mac to Apple Store to fix all these issues. AppleInsider is also confirmed Disaplay Flicker issue on some of the models that they tested.

Iphone 5S low light video recording is very dark :(

Hello Friends,
I bought a new iphone 5S and its few days only since i have been using this phone
and i never tested video camera before.
recently i came to know while taking some video in a low light situation, i noticed that the video is **** dark and
it looks pathetic though in image mode the camera appeares to be good and its clearly brighter.
but when i switch to video mode it becomes very darker.
I did some comparison just to confirm my suspicion and in fact it turns out that videos are worse quality than videos that i shot with my iphone 4S, i tried all possible settings but nothing worked,
i did restore my phone twice by assuming it is a software issue however i still believe it might be a software issue because when i am using 3rd party app to take video everything is perfect. even if i am using the same camera feature through imessage/whatsapp by directly accessing camera it works fine.
i don't know what exactly the problem is
please friends help me....if anyone has faced the similar problem.
Thank you

Hello there, ankitnavgwal.
Good job on troubleshooting your issue so far. The following Knowledge Base article offers a great checkllist of practical steps for troubleshooting issues with iOS not functioning as expected:
iOS: Not responding or does not turn on - Apple Support
If a single application is not responding or stops responding when it opens, you can force it to close.
If the device is unresponsive or if certain controls aren't working as expected, restart your device.
If the device remains unresponsive or does not turn on (or power on), reset your device.
If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
If you are using an iPad, ensure that it's connected to the USB Power Adapter supplied with the device.
Let it charge for at least twenty minutes, then see if it starts normally.
If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
If the screen displays a red battery icon, continue charging the device until the battery is fully charged. Learn more about charging iPhone and iPod touch, or iPad.
If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
Connect the device to your computer and open iTunes.
If the device appears in iTunes, select and click Restore on the Summary pane. Learn more about restoring iOS software.
If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.
If the above steps do not resolve the issue, contact Apple.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

Mobility Radeon HD 5000 Series + open source driver = screen flickers

Hello, this is my first post here. I just finished setting up my first arch installation on my laptop and I'm using Xorg + gnome 3 as user interface.
My laptop has two VGA cards, an integrated intel VGA card and a Mobility Radeon HD 5000 Series, so I used vgaswitcheroo to switch to the Mobility Radeon and turned off the intel VGA card.
Now, here's the problem: I want 3d acceleration to play games and such, but the opensource radeon driver is being weird.
Basically, if I use my Mobility Radeon and the opensource driver the lower-center part of the screen flickers when i move windows vertically. It flickers to black in a polygon-like area and the window shadows get all messed up. If i try to start a game that uses 3d acceleration (such as nexuiz) it runs extremely slow (way too slow for this VGA card) and flickers like crazy in the same area and sometimes on the entire screen.
I already tried using the proprietary driver (catalyst) but it doesn't seem to support switchable VGA cards, since it gives me memory segmentation error.
However, if I switch back to the Intel VGA card and use the opensource intel driver, it runs just fine with no flickering and nexuiz runs better (but of course not fast enough since the intel VGA card is crappy)
As you can see here, 3D acceleration seems to be enabled and Xorg doesn't seem to give any major error or warning:
