Vario Laptop-Wndows 8.1 Monitor Flickers and Input is intermittent
My Sony Vario Laptop running on Windows 8.1 occasionally starts flickering and when I try and input data it only accepts occasionally. How do I troubleshoot this problem?
Does it flicker only within Windows or BIOS also?
Attach Sony Vaio Laptop to an external monitor and check if it does flicker there. If it doesn't it should be caused by the LCD panel it self. If that be the case
then you have to contact the authorised technician to get things done. May be a replacement will resolve the issue.
Otherwise:
Update the display card driver to the latest version
You may need to run the display troubleshooting tool by going to
Start -> Control Panel -> Troubleshooting ->
Appearance and Personalization -> Display Quality
You can also go for a System Restore. Select any restore point when there was no such issue.

EX630 laptop - Nvidia 9300M GS - monitor flickers at 1920x1200
Recently, I bought an MSI-EX630 Laptop with NVIDIA SLI GeForce 9300M GS card from Newegg.
Never, ever, ever, buy a laptop that is from MSI or has NVIDIA inside that you cannot return, NEVER!
In short, my story is that when I hook up a secondary monitor it starts to flicker at resolutions of 1920x1200. This only happens when the laptop screen is active as well. This happens no matter if I have a HDMI-to-DVI cable or a simple VGA cable.
2) When I try to upgrade drivers, from official MSI site, everything goes blank (even when I'm on single-laptop-monitor configuration). Turns out, I have to go into Vista safe mode, to turn off the secondary video card, and use only the slow one, otherwise I get blank
screen with the mouse only...
3) with original drivers and configuration, single monitor, when I leave the laptop for 2-3 minutes, and then I try to move the mouse - I get a message saying to wait. I guess while the laptop was idle, the boost video card deactivated, and now to get active again I have to wait..
So, when I brought it to MSI Toronto for service, I got this response:
Hi,
The resolution of EX630 is 1366x768. It is the highest it got. If you connect it to an external monitor, you only got 1366x768. It won’t run under 1920x1200 resolution.
We have tested your notebook and the dvi cable. They are all ok. Your computer will be sent out to you soon.
Regards,
Harry with MSI(Canada)
(905)707-1880 ext 119
The good about MSI, is that you can go and talk in person with their service people. The bad, is that they cannot speak English and have very little idea about their products.
I told Harry, that there are two video cards in the laptop, and I suspect the secondary, faster card has issues.
Harry told me: "Who installed the second video card for you?"
Me: "This is NVIDIA SLI configuration, it comes with two cards, one built-in that is slower, and a secondary one, that boosts performance in games".
Harry then said that he has to ask his technician in Asia.. Harry later on told me that he has to bring the laptop to factory settings and whether I give permission to do that..
On the RMA sheet of paper that he asked me to sign, I specifically said that he can reformat the disk - no problem and that I've already used the MSI recovery disk to bring back everything as original..
But I guess better ask twice that sorry, can't blame them for that..
I asked to speak to a manager, but to no avail.. Harry suggested he'd ask his technician again..
I even put a youtube video to demonstrate to people the first problem that I have:
NVIDIA refuses to talk to me, because their product is in a laptop, so I have to talk to the laptop manufacturer..
So, I went to a store with 14-day return policy and bought another MSI - CR600, with 8200GS Nvidia card.
Needless to say, 1920x1200 works just fine with same cables and monitor. This MSI-CR600 laptop, at least I can return, and I'll do it.I have a similar issue: external Samsung monitor worked fine on Vista, but I could not stand Vista. I put Win Xp Pro on... and I cannot get any signal out through the VGA port now. The monitor works fine (still), tested with two other latptops.
My suspicion is that the nVidia driver files, possibly the .INF, may need tweaking / replacement / etc.
Any assistance appreciated. -
Monitor flickered and not iMAC won't boot up
My iMAC 24; purchased in late 2008, the screen started flickering recently. Top half of the screen would flicker and the bottom half is black. The only option is to do a hard book by holding the power button. Now on the reboot I get the Apple icon and than the spinning gear but about 1 minute the gear stops. On some reboots I'm able to get in and everything is fine but than soon after the flickering starts up again. The strange thing is upon the reboot after the gear stops spinning it does seems to be still be running and the screen is just frozen. I saw post about a firmware update however I can't update the firmware because I can't boot up. I've tried booting from disk but I get stuck at the same spot. I tried booting in Safe Mode, I get the black screen with a lot of white text but that's it. The only possible error I see is, BootCacheControl: Unable to open /var/db/bootCache.playlist: 2 No such file or directory, but don't know what that means.
Any ideas and/or help?Safe Mode didn't work, just gave me lots of details with no error.
Huh? Sounds like you booted in verbose mode not safe mode. And it fully booted or didn't? -
ThinkPad W530 on Windows 8 - dual monitoring flickers and resets resolution evey minute
I am not able to run presentations from my ThinkPad W530 while duplicating the monitor to a beamer. The monitor will flicker and reset its resolution every minute. I have already tried updating drivers, setting BIOS mode to discrete, using different resolutions, but nothing helped. As such, the device is useless when I would need it most importantly, to give presentations.
Thanks in advance for any help in resolving this really disturbing issue.Are you attaching it via VGA or DisplayPort?

Macbook pro monitor flickers and audio interference
Hi there,
I've noticed some strange behavior with my macbook pro lately. Occasionally the monitor will flicker just once really quickly. It will flicker between black and the regular screen. Maybe it happens about twice a day. When I'm surfing, I noticed some interference with the music that is playing in Itunes. For example, if I click on a link in Google Chrome, the audio signal from whatever is playing in Itunes will get cut for a split second. It's almost like the processor is working too hard to manage both surfing in Chrome and the music playing in Itunes, which is ridiculous. When I bought my computer (2008 or 2009 model), I upped the RAM to 4gb. My processor is 2.4 ghz. I have no idea what's going on. Is it a hard drive problem? Hope you can help.
Thanks!Do you have access to an Apple Store? If so, it may be worth making an appointment at the genius bar and having them run the test for the NVIDIA problem. Since your replacement logic board still has the NVIDIA GeForce 8600 M GT video chip, it could be starting to happen to your replacement logic board.
I also agree with all of CMCSK's suggestions. Freezing is often associated with hard drive problems. You might also want to run SMART Utility:
http://www.apple.com/downloads/macosx/systemdiskutilities/smartutility.html
You can download the demo and run it several times for free. It will give you a very comprehensive view of the physical health of your hard drive. If you still have the original one from 2007, it's getting pretty long in the tooth and may be approaching the end of its average useful life of 3-5 years. I just recently had to replace my original 2007 Fujitsu drive.
If your drive is headed south, and is also too small, it may be time to upgrade to a larger and faster drive.
The software update probably didn't cause the problems, but it may have exposed problems that were already in existence.
Good luck! -
Sometimes the white portion of the screen turn aqua and when I move the top cover it flickers back and forth but often stays aqua. As my power source has juiced up the machine, it looks like it may have disappeared. Maybe it just does this when the battery is not powered up above 50%???

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. -
External Disply flickers and went Black for a short duration after yosemite update 10.10.2
hi,
i got a mac book pro late 2008 and since todays update my external monitor flickers and went black for a short duration.
It seems that it happens, when i start a new app or i move a window across the displays.
Disabling the automated scaling of the resolution reduced the flickering but it still happens.
Does anyone faces the same problems and have an idea how to fix it?
I would appreciate it.
Sincerely
LukasHello lukasfromholzwickede,
Thanks for participating in the Apple Support Communities.
It sounds like you've noticed flickering on your external display after updating OS X Yosemite.
I'd recommend starting with these resets to troubleshoot the situation:
You can reset the Mac's parameter RAM and SMC.
You can find these steps in this article:
Apple computers: Troubleshooting issues with video on internal or external displays - Apple Support
If the behavior continues, try going through the steps in the "Update your software and firmware" and "No video or no signal, image distortion, 'snow,' or flickering" sections of this article, as well.
All the best,

My parents currently have a Dell Inspiron desktop (which thanks to Windows has crashed and requred re-installation of the OS and then ordering an OEM hard drive and starting from scratch). Anyway, my dad has started bringing home a work laptop, and I got him a laptop docking station so he could take advantage of the 23" monitor, keyboard, and wireless mouse that he prefers.
My brother and I are going to buy my parents at Mac Mini for Christmas. It's probably simple (or with my luck, impossible) but I need to know what I need to know in order to also hook up the Mac Mini to the monitor/keyboard/mouse (we may buy a keyboard and mouse). Is it just a matter of cables/splitters?
I'd appreciate any assistance. I've been trying to get my parents switched over to Mac for almost 10 years now. Dad is stubborn and will definitely want to use the 23" monitor he bought so I have to find a way to make that work. The keyboard and mouse aren't a huge deal - instead of being on the drawer that rolls out from under the desk, the Mac stuff can be on top of the desk. I just need to know if it's possible to avoid that and do everything through the docking station (even if I have to get a USB hub). I'm pretty sure the monitor has a DVI input, and the current work laptop is using the analog input.
Thanks all.The Mac mini is not going to be able to use the Dell docking station itself, due to
the Mac mini is not a laptop
it does not have a docking connector
However you might be able to achieve what you want with a KVM (Keyboard, Video, and Mouse) switchbox which would sit between the dock and Mac mini and the Screen/Keyboard/Mouse.
For this to be as easy as possible, both computers need to be using the same types of connections, so that means USB for the keyboard and mouse, and ideally DVI for the monitor. I am using a dock with a Dell laptop and the dock does have a DVI connection as well as a VGA connection so yours might as well.
You would then need a KVM switchbox with USB and DVI connections. This one would be a suitable example http://www.amazon.com/TRENDnet-2-Port-Switch-Audio-TK-214i/dp/B004L62KN4/ref=sr_ 1_4?s=electronics&ie=UTF8&qid=1322228493&sr=1-4 you don't have to use the audio connections.
In theory you could use a VGA adaptor on the Mac mini to make both use VGA but widespread reports suggest VGA on the latest Mac mini is very unrealiable. -
Can anybody help?
I am considering buying a new MAC laptop to run LOGIC for composition and band live/recording, but which one is best as I do not want to spend too much money?
Does it have a line in and how do you monitor sound?
Will I need adaptors and an interface?
Also, I am guessing as Logic only runs on MAC surely then they would not the best spec to recommend to run it?
I see all the upgrades as additional memory or a faster process?
Is a retina screen necessary, and why flash based storage against a 1TB hard drive, and a i5 instead of an i7
The main reason for this purchase is to play live and use backing tracks and record found sounds and make creative songs.
I hope you can provide some valuable feedback, as I am a longtime MAC user and see upgrades and changes happen regularly but the most important thing is the songs not the equipment.
I have £500 already and willing to add another 500 to 700 pounds, then software extra.Can anybody help?

Why is my 2007 HP V17 monitor screen flickering and going black?
I have an old 2007 HP V17 monitor attached with a VGA cable to an early 2008 Macbook running on OS 10.6.8 software via a DVI- mini connector (this is also my desktop computer).
About 6 months ago, the HP display started going white and sometimes gray for a few seconds before the image would return, and a couple of times I had to unplug it and restart the Macbook before it came back. I followed Apple's instructions for testing whether the problem was in the computer (= resetting the system by resetting the Mac's parameter RAM and SMC), but the computer tested okay. I then purchased a new VGA cable and DVI-mini connector, but the problem persisted.
Today the HP screen suddenly went black (first time going black) and stayed black. The power button stayed lit and if I pressed the Volume or Auto buttons, the "Volume" etc. message boxes did appear, so the device's backlight is apparently working and not burnt out (unless the backlight has nothing to do with the message boxes showing up, which for all I know may be the case). However, the Desktop showed up only on the Macbook.
I checked all the connections, removed the DVI connector and plugged it back into the Macbook several times, but the HP screen stayed black, so I removed the DVI connector in order to type this message on the Macbook. Then, as I was writing this, I decided to plug it back into the Macbook one more time--and sure enough, the display is back!
I love this monitor, which is the perfect size and ergonomic height for my setup, so I'd hate to have to replace it. Can anyone tell me
Given the information above, what's the probable reason for the flickering and going to black? If it's the computer, what could it be? Can I solve this problem myself? (See above; I couldn't find any other ways to test the computer in the Apple articles database.)
If not, could a monitor this old be repaired?
If so, how much would repairing it cost, since buying a new monitor that I probably wouldn't like as much would cost upwards of $300?
Thanks so much for any advice out there!Hello @turtlewiz,
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 HP V17 Monitor has gone black and is not displaying anything. I am providing you with some steps for you to try below:
Step 1. Unplug the power cord from the back of the monitor and the wall
Step 2. Hold the power button down for at least one minute
Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
Step 4. Press the Menu button on the monitor
Step 5. Navigate to the Factory Reset option and select it
If the issue persists after this you can try the monitor on another computer to see if it continues. If it does it appears to be a physical issue and I think it would be best if you contact HP Technical Support for repair options.

Monitor flickering requires power unplug/replug
I'm using an HP w2558hc monitor on a T60 running Windows XP Professional with an ATI Mobility Radeon X1400 display adapter. Everytime I reboot the laptop there's a rapid left/right jiggling of the display, which is noticeable enough but more so when you look toward the edges of the screen. By trial and error I found if I unplug the monitor from the wall power outlet, wait 10 seconds and plug it back in the problem goes away until the next reboot.
HP tells me it must be the laptop's display adapter because they had me plug the monitor into an old Dell 2100 tower I had hanging around (Windows 2000 on an Intel 810 graphics card) and it did not exhibit the problem (albeit that 10 yo PC only went to 1600 x 1200). Also because the flickering doesn't start until the Win logon prompt appears, which is when they say the graphics adapter kicks in. And theres no flicker if I turn the monitor on without connecting it to the laptop to display the "No Video Input" message.
I have tried the following remedies without success.
- Updated the T60 graphics driver to the most recent one Windows Update could find (version 8.362.0.0, 4/5/2007)
- Uninstalled the HP driver and went plug and play
I posted this if case anyone has a similar problem, at least I found a workaround. The unplug option is only slightly annoying, although if the adapter is truly at fault I can't see why unplugging the power cord stops the shaking. (Simpy cycling the monitor off and on with the power switch won't fix it. I power off, then unplug.)
If anyone has any other ideas I might try I'd be glad to hear them. Lenovo hardware support suggested I try installing the Presentation Director, has anyone fixed any similar problems that way?My problem is that unplugging the monitor does not help.
By changing the resolution a few times I can fix the screen flicker problem but then get a single verticle line of horizontal lines on the right side of my monitor that increase in speed as time goes by.
It is the lesser of two evils so I just use 5/6 of my monitor and cannot see the lines against a black background. -
Tecra M5: External monitor flickers - grounding issue?
Hi,
I just bought a new Acer Full HD LCD Monitor (P244W) and have tried connecting it to the VGA port of my Tecra M5.
It works, but there's a noticable and increasingly annoying flickering. I tried it with both XP (SP3) and now Vista (SP1) and it happens for both. I have the latest BIOS and NVidia drivers. The actual laptop LCD screen still works fine, its just the external monitor that flickers.
To ensure there was nothing wrong with the monitor, I connected it to the VGA port on the ATI video card on my desktop pc and it displayed fine without any flickering.
After browsing the web for people having similar problems, I've narrowed it down to it being caused by my AC Adapter having a grounding problem as the flickering dissapears as soon as I disconnect the AC Adapter and just run from the battery. It the seems the common solutons to this problem are:
1) Try some different VGA cables with better shielding from interference.
I tried this and it made no difference. I tried cables both with and without the ferrite magnet/choke thingy's at both ends of the cable and the flickering remained.
2) Try different screen resolutions and refresh rates.
Tried setting some lower resolutions, but the flickering remained (besides I'd rather keep the 1920x1080 native resolution for my monitor). The NVidia driver only allows 60Hz for the refresh rate at 1920x1080, so I couldn't change this.
3) Ensure both the laptop AC Adapter and the monitor are connected to the same wall socket and are on the same power extension board.
Tried this, but didn't fix it.
4) Run an extension cable to another power circuit in my house and power the AC Adapter and monitor from this to see if its something wrong with the wall socket im using.
Tried connecting to a wall socket in my laundry, but didn't fix it.
5) Try using a different power extension board and ensure nothing else is connected on it other than the AC Adapter and the monitor.
Tried this, but didn't fix it.
6) Get a 3 prong to 2 prong adapter, so the AC Adapter is no longer grounded.
Most people on the web seem to say this fixes the problem, but I'm not sure how safe it is to leave it this way in the long run. Especially, when stories of laptops catching on fire are becoming more common.
7) Get a generic brand AC Adapter as these sometimes deal with the grounding problem better than the Toshiba AC Adapter.
Again, I'd rather avoid this option as even the generic branded ones are expensive.
8) Remove the battery and run from the AC Adapter on its own.
Tried this, but didn't fix it.
9) Fiddle about with the monitors settings.
Tried this, but none of the settings fixed it.
So, what are my options?
Is there a known cause & solution to this problem?
If my laptop is still under warranty, can I get a replacement AC Adapter or something to workaround this problem?
Thanks
Message was edited by: shaneh20
Message was edited by: shaneh20I finally figured it out. Just for laughs and because it was the only thing I hadn't tried, I tried using a different 3 prong power cable that I had lying around, connected it to my monitor and the flickering dissapeared. *So, the power cable that came with my Acer monitor was dodgy and not my Toshy's AC Adapter like I first thought.*
I'm guessing the dodgy power cable was preventing the monitor from grounding properly, so instead it tried to ground itself using my laptop's power cable, going via the VGA cable
. This would explain why the problem seemed to go away whenever I unplugged my laptop's power cable and also why there was interference. -
I just bought a new external monitor (ASUS), and it have DVI and VGA plugs. I bought the DVI adapter to connect with my macbook pro laptop. But the external monitor remain black… so I turn it off then turn it back on, it said "No VGA signal". Does it means I have to use VGA adapter instead? I am not sure how it work, I am very new to it… I hope you can help me out!

External monitor flickers when waking up from sleep
I use an external monitor with my new MacBook. All works well, but I have noticed that if I start using the external after the screen has gone to sleep, I sometimes get a problem on the external where the screen flickers and breaks up. If I disconnect and reconnect the Mini DisplayPort then the problem resolves, has anyone else seen this?
TonyI have the same issue with my new macbook.
When i wake the computer from a partial sleep the screen flickers and i get line distortion through the image.
If i put the machine to sleep unplug the mini dvi adapter and replug it in and wake the computer up the problem disappears.
The issue is also intermittent doing about 3 times out of every 10 wake ups...
If anyone has any suggestions it would be great, I a using a new Dell 2208WFP monitor.
