Monitor flickers to black

Every once in a while, my monitor will show some black lines flickering across the screen and turn black for a few seconds. It then flashes black for a few minutes and goes away. This started about 1-2 months ago and happens once a week or once every other week. I have not noticed a correlation between cell phone usage or other interference. Any ideas?

I guess it's good we're not hearing a litany of complaints on the subject : )
Can anyone with a black or white MacBook confirm that they are able to use the mini-DVI-to-DVI adaptor with external monitors with none of these flickering issues?

Need help/advice for XB270HU monitor. G-SYNC does not work. Monitor Flickers. No signal.

I recently bought this Monitor and have been having constant issues with it. Before I start, here are my specs.
GPU:GTX Asus Strix 970
CPU:i5 4690k @3.5GHz
RAM:16gb
OS:Windows 7
All my drivers are up to date, and in the NVidia control panel G-Sync is turned on. However while gaming I still get horrible stutters everytime the FPS fluctuates even a tiny bit even going from 140FPS down to 90 FPS. I was under the impression that changes to FPS it would remain smooth down to 30/40 FPS? Not so at all. There is no difference between this and my old monitor besides the fact that it can go up to 144hz.
Secondly everytime I turn on the monitor, it goes black and says no signal and then proceeds to launch at 800:600 resolution, flicker black, 1920:1080, flicker again and arrive at 2560:1440. Sometimes it wont ever receive a signal and my second monitor will turn on instead and take place as primary monitor.
It is plugged into the Display port and is secure, as far as I can tell the chord is in good condition.
And finally sometimes during gameplay, ableit rarely, I get random flickers of black screen for half a second here and there. When this occurs it happens about 3-4 times and then stops. Worrisome!
Part of me hopes that I have a terrible, broken and faulty monitor and could get a replacement. Because then I wouldnt try to justify why I spent nearly $1,000 dollars before tax for this thing. But then the other half of me would not even want to get a replacement because of how big of a let down this one has been. I'd rather just never have bought this one at all and have my money back.
Any help or suggestions are appreciated. If anybody has had similar problems please speak up!!

Booserbob,
If you are willing, I would like to see about having a new Display Port cable sent out to see if that resolves it. If it does, I would be interested in obtaining the cable you received with the monitor, I have been trying to get one from a customer having this issue with no success as of yet. If you are interested, send me a PM (private message) with the following information and I will get to work on it:

My secondary monitor flashes and blacks out after the 10.7 install. Any ideas on how to fix this?

I have installed 10.7 and the secondary monitor flashes and blacks out. I downgraded back to 10.6 and the problem went away. I reinstalled 10.7 and the same problem happened again. The monitor blacks in and out especially when the pointer is placed in the dock area, but it still happens all the time. My secondary monitor is a ViewSonic 22 inch that is connected to a DVI to display adapter. Any solutions??
Thanks

Talked to AppleCare and it's most likely the fact that my MacBook has 3.0 USB ports and my non official charging cable can't support that. So yeah, I'll try a new cable, hopefully that's the fix.

The monitor fade to black sometimes!

hi, i'm from chile and i writing here because i can't find an answer for my problem, I hav a KT6 Delta whit an Athlon XP 2200+, 512 Mb RAM and a MSI FX5200 TD128 gfx adapter, the problem is that sometimes the monitor fade to black by 1 - 2 sec. and come back, this fade is assemble with the tipical sound "tac" of a relay, like when the monitor's resolution change.

PD:sorry for my english!

English is the language around here. There might be many who wants to know how you got your problem, and if and how it was fixed. And it is not always there are such bilingual computer experts as Osnavi around.
Please tell us more about your PSU. There is a sticker on it, inside.
Would you please also enter Device manager while in Safe Mode, to see what is said about your video card there.

HP monitor 2009m goes black on a reandom basis. Starting in safe mode (as recommended) OK once but not every time. What is causing the problem and how does the problem get fixed?

Eric Ross,
Hi,
I did as You indicated and found on the top left hot corner was set to "put display to sleep" and the lower left hot corner was set to " disable screen saver", Both Right side upper and lower hot corners were not set (they had a -)
So, I adjusted the two "set" hot corners to - to match the other two. No incidents since of any display going black on a intermittent basis or at all, Thank You Very Much for Your Reply and Insight! Will post as "Correct Answer"

HDMI Monitor flickers

I have an VGA Monitor connected via adaptor to the HDMI port as a second Monitor to my Thunderbolt display. The VGA Monitor flickers and it was suggested to upgrade the firmware. But the system tells me the firmware is not for my system (Mac mini Model A1347 from autumn 2011).
How can I fix this problem?

What monitor(s)...?
If one has (Digital) DVI input, then you should use it on the HDMI port with the Apple Supplied HDMI to DVI adapter and a good DVI cable.
If both have (Digital) DVI input, then it would be best if the second one was also on a Thunderbolt/MiniDisplay Port to DVI adapter instead of analog VGA.

Monitor flickers

Greetings,
I have a new mac mini with 16 mb memory, 2 T hd and acer 24" monitor connected to the DVI to usb connection. Latley and from some unknow reason , the monitor flickers every once and a while.
Is there an issue with the mac mini? Or the video card in the mac mini? Or is there some issue with the monitor compatibility?

Computer Monitor Flickers

My computer monitor flickers if we tap it on the side it stops, then starts up again, sometimes we go hours and not problem, other times it drives us nuts, We have a Gateway computer, it works fine except for this monitor problem, it was purchased in 2004, it has a "nvidia GE Force 2 MX 400 video card, I checked with Nvidia and tried downloading the latest driver but then the computer wouldn't start so I had to go back to a previous date so that the computer would start, do I need to look at getting a new monitor? IF so what sort of monitor would be best, someone said the resolution would not be good on a wide screen, but the only ones I have found at Best Buy and other places are the wide screens. I hope someone can suggest a solution so we can enjoy this second computer and stop hitting the monitor
thanks Lea

I'm having a similar flickering problem with the LG widescreen LCD monitor which came with our first Vista computer (an HP desktop, purchased about a year after Vista came out). It mostly only seems to flicker when I'm playing games with animations in the graphics (such as Civilization IV or Astral Masters). The most common suggestion I found (f.ex. in the HP Help & Support area preinstalled on my computer) was to increase the refresh rate. Doing this has not eliminated the flickering, but has lessened the severity somewhat (it just flickers as vertical lines or bars at 75hz; at the default of 60hz it flickered as both vertical and horizontal lines). I ran HP's Monitor Diagnostic Tool (which included a simple wireframe animation), and it didn't turn up any problems.
Hockeycanuckjc's suggestions sound pretty practical, and I'll try them. I've also seen on another thread on this board that Nvidia graphics cards (my HP computer has an Nvidia Geforce 8500GT) can have issues with the drivers, especially after Windows Vista has just automatically downloaded its latest updates -- so it's possible that the graphics card driver could be getting cranky (though I haven't yet confirmed or denied that theory in regard to my own computer).
I think my HP computer is still covered under its Extended Service Plan (though I'd have to check the sales receipt to be sure), but I want to do as much troubleshooting as I can before calling Best Buy tech support, so I'll be able to explain my problem more knowledgeably, and hopefully not have to jump through as many hoops as usual before they authorize an in-home service call.

My iMac monitor just goes black

I have a 2009 27inch iMac with an external Samsung monitor.
Out of the blue, the iMAC MONITOR just goes black. Like it went to sleep or something.
This has happened 4 times in the last 2 weeks. (luckily I can restart the computer because the external Samsung still works.
I restart the computer and the monitor works fine again.
Help.
Thanks.

Hi.
Screen goes totally black.
The good news is, I read around and was advised to turn off the computer and unplug it, and plug it back in and start up. That seems to have fixed it. So far, so good.
Thanks.

X1 Fading/flickering to black and white and then returning to color,

X1 Fading/flickering to black and white and then returning to color, video lags, image moves up and down I have had the X1 for almost 1 year and it is really acting up. It flickers/fades to black and white, the video lags on ocassion, and the image moves u and down constantly. i own a sony trintiron CRTV and it is not the tv because the tv does not do this on other inputs. Anyone know what might the issue?

Is this an SD TV set? Or does it have HD capability? How is it connected???
If it is an HDTV and you are using component connections, I suspect you need to verify the X1 box is outputting the correct resolution. Using the Comcast remote press EXIT EXIT EXIT 480. If that works and you know for sure you have an HD capable TV then press EXIT EXIT EXIT 1080

Lenovo Monitor Flickers constantly

Hi All,
I have a Lenovo L197 Wide connected to a Server 2003 box (also lenovo) and the monitor flickers constantly. The refresh rate is set to default and I can't change it to see if it has any effect.
Anyone any ideas?
Cheers
Andy.

welcome to the forum.
are you using fluorescent lights nearby? if so, does the monitor still flicker with the light(s) turned off?
have you tested the monitor on another computer, with a different cable, with a different video card, or a different monitor altogether with the server 2003 machine to eliminate any variables?
if the above checks out then your L197 either has a defective inverter or its backlight is failing. warranty is your best option in this case.

Program monitor keeps going black in Premiere Pro CC

PC - Premiere Pro CC - AMD Fire Pro (13.101-130604a-158071E-ATI)
I'm working on a project and the program monitor keeps going black in Premiere Pro CC while I am working on the timeline. I've got like 28 GB of memory alocated to the program and just updated the latest driver for my video card. No clue why this keeps happening, but the only way I can get around it is to restart. When I go to close down the program freezes and I have to shut it down in the system preferences.
Under a crazy deadline if you can help? Thanks

here's my story. I'm also having this problem with video appearing in the Program monitor. The only thing I did differently is that yesterday when I was editing, I pulled the Program monitor out of the main Premiere interface and dragged it over to my second desktop monitor. that worked just dandy.
when I opened Premiere today, and opened an entierly different project, there was no video in the output window (and it was locked back into the main interface). I also can't select clips on the TL. The software locks up, and I have to restart.
I am able to create a new project and render the countdown leader. I was also able to import the project that wasn't displaying correctly, and have it work just like normal. So I think I'm back in business for now.
I'm deeply concerned though. I'm doing a webinar about Premiere very soon (with rehearsals tomorrow!). A failure like this looks bad for everybody. Also, I don't relish having to re-import all of my old projects in this way to get the basics working again. Any idea what went wrong? Right now I feel like I'd better never drag the program window to a second monitor to enjoy a larger program monitor while editing.

I haven't installed any new software that I know of between the last time I edited with the Program on monitor #2 and right now.

Photoshop Creative Cloud flickers and blacks out

I posted this in the Creative Cloud forum, but was told to post it here.   I am sure it is only a Photoshop Creative Cloud problem.
I am using Photoshop Creative Cloud, on trial. I have been using Photoshop, desktop version, for 20 years. Never saw this problem on it.
PS CC flickers and blacks out. Many times, many different files, many different actions cause this.    Right now, I am editing a photo, and using the Magic Wand tool to select areas that I will remove from photo.   PS CC is flickering on my screen, on/off.    Sometimes it goes completely black.
I can see the menus, but the image itself is flickering on/off. Mostly off.
Thanks

Yes flecking is a common problem. If happen for many bugs. That is why I posted the search instead of trying to answer your question for you posted little information bout your problem. In the guidelines you will see
=============================
Supply pertinent information for quicker answers
The more information you supply about your situation, the better equipped other community members will be to answer. Consider including the following in your question:
Adobe product and version number
Operating system and version number
The full text of any error message(s)
What you were doing when the problem occurred
Screenshots of the problem
Computer hardware, such as CPU; GPU; amount of RAM; etc.
=================================================
Information like that help to identify if you have a known problem from what your using and help pinpoint where the problem may be .   Even if you have the latest OS it its updates. The latest video driver and the latest Photoshop update does not mean you will not have any software and hardware bugs. Just because there have be problem reported about flecking in Photoshop in all supported Platforms OS versions does not mean that there is a single common problem in Photoshop. All it means is that flickering is a common side effect caused by bugs.

Monitors flickering badly after Yosemite Install

Monitor flickering badly after Yosemite installed
I will be awaiting upDated drivers in a release soon.
I notice is very badly when I connect my iphone to ITunes screen
goes crazy flicker. . . . Anyone else having this issue ?

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
     computer and after the chime press and hold down the OPTION key until the boot manager
     screen appears. Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
4. Reinstall Yosemite: Reboot from the Recovery HD. Select Reinstall OS X from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
