Screen flicker on external monitor

Has anyone had any experience with screen flicker on an external monitor? I connected my laptop to an external monitor and I get consistent flicker on the whole screen. If anyone can help, or could help pointing me to website etc. I'd appreciate it.

Good suggestions guys I'll put out some more information. The cable is ok (good thought to check for it). I plugged my vga cable to my tv and do not get the screen flicker. Also I'm using the ati driver which possibly has the same problem as the intel, one. I configured my xorg.conf as describe in the wiki xrandr page:
http://wiki.archlinux.org/index.php/Xra … _xorg.conf
One thing that I noticed that is a bit odd is the xrandr reports the display rate as 60.1. I've never seen this before so right now I'm thinking that it has to do with that.
xrandr
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 1440 x 1440
VGA-0 connected 1440x900+0+0 (normal left inverted right x axis y axis) 410mm x 257mm
1440x900 60.1 + 75.0*
1400x1050 74.9 60.0
Still up the river so any more suggestions would be definitely appreciated.

IMac early 2008 occasional screen flicker with external monitor

I am experiencing flickering with my early 2008 iMac when driving an external monitor. My Thinkpad is flawless when pushing out to the monitor.
It will be fine, but occassionaly (every 5-20seconds) the screen gives a little flicker, about 1/4 of a second in duration.
Also, sometimes, there is no flickering, it depends on what is being displayed, which makes me think video card. I am using the 2400XT and my software is up to date.
ROM Revision: 113-B2250H-259
EFI Driver Version: 01.00.259
I am thinking about trying to source a 2600pro that came on the more high end version of my iMac and swap out the graphics card. I also want to drop a 2TB hdd in it, so I figure I might as well kill 2 birds with one stone, or kill 1 iMac with 2 simutaneous upgrades if I am unlucky! (o_O)

iMacs are not designed to have the graphics cards upgraded. If your old card is bad and you feel competent to exchange it for the same one that's really your only GPU option. Apple never said the iMac GPU's were upgradeable and frankly I've never heard of anyone successfully upgrading an iMac GPU.
As far as the adaptor well you could bring your system into an Apple Store and have it checked out by a Genius, it's a free service. I don't know how to make a reservation in Japan but I'm sure you can from the Japanese Apple site. The link in the US is:
http://www.apple.com/buy/locator/service/
I'm providing that so you can look for something equivalent.

How to switch off internal macbook screen when using external monitor(s)

as far as i observed, adding external displays ( running different screens on them, not mirroring) to a macbook pro increases the gpu workload and with that comes temperature rise in the laptop and increase in ventilator noise - and probably increased hardware aging and risk of component faillure due to high temperature inside the laptop.
simply try connecting two external 27" screens and open some flash video on both of them. then run a temperature monitoring software and watch temps rise, compared to running same flash videos / demanding tasks only on one connected external screen or only on the laptop screen with no external monitor connected.
especially in mavericks, due to its increased background routines, such a set-up appears ever the more taxing, then again who does not love apple`s nice adds showing laptops with two 27” screens connected to it and the workspace vision they invoke....
i have seen temps around 100° to 102° celsius on a 13" macbook pro 2012 edition, which i would expect is territory where the cpu / gpu temp safety switches will trigger system shutdown any time soon ( hardware status before verified as fully in order by apple service and default osx installation)
imagine your anti-virus software starting some realtime content screening while runnign some demanding tasks already and the system shuts down easily (all such situation observed in reality)
(would be interesting to see how a retina display macbook fares with 2 external monitors running demanding tasks, considering the retina display already increased taxing for the gpu - any experience from users of such a setup would be very much appreciated as it will provide critical purchase decision intelligence for all of us envisioning a retina-book and two big screens adoring our desks...)
turning down the macbook`s built-in screen`s backlight may reduce power consumption but i have not seen any evidence that it switches off the gpu-to-screen feed and respective gpu load - it certainly did not prevent gpu, cpu, board, etc temps to rise to borderline levels.
so the key question here is, how to switch off the macbook pro`s built-in screen in order to avoid gpu cycles being wasted on that screen ( and the resulting heat developments) when working with big external screen(s) connected to the laptop ?

this thread talks about running several monitors as advertised by apple and running demanding task on them.
with the lid open, the keyboard offers a very efficiant heat escape vector, which is blocked when the lid is closed - this is a basic and commonsense insulation effect. this thread also mentions the use of temperature monitoring software and thus a repeatable test setup. the temps recorded were also mentioned. they rose when the lid was closed, the running task remaining unchanged. as far as i could track down the cpus in discussion will shut down around the 105 degree celsius range. i observed system shut downs when the system approached 103° celsius. not to mention that the fans will run loud well before that.
again this is on hardware checked and ok-ed by apple service.
the question still welcoming an expert answer: is there any way to switch off the built-in macbook monitor while the lid is open ?

How do I make the DVD player play full screen in my external monitor instead of my laptop?

I just upgraded to Lion, and I have my laptop screen and my external monitor, and every time I tell my computer to play a DVD in full screen, it makes the full screen slide over from my giant external montior to my tiny laptop screen. How do I make it not do this? I would like to be able to watch my DVDs on the larger high-res monitor instead of my tiny laptop screen, but I can't seem to find the right preferences window or something.

With DVD player open, have you check the menu bar > Window > Show/Hide Controller?

Screen flicker with multiple monitors

I tried plugging an external monitor into my laptop and though the second screen came up it caused both screens to flicker continuously with horizontal lines going across. This happened both when I used xrandr manually and when I used the Gnome control panel. It's been a while since I used an external monitor so I'm not sure if a particular update broke anything. Any help would be appreciated.

Try to run all displays in the same resolution (the settings of the less advanced, smaller display, not the other way around). Additional displays require additional processing, close other applications. Unplug the 23" for now, try it when you've got everything else running. Restart connected computers after you've changed settings on any detectable display. Make sure the bandwidth is sufficient for screen sharing on both ends. (I would use Spaces on the remote computer to create speedy access to applications.) When this works, try to connect the external display.

How to blank laptop screen when using external monitor/

Hi there
I need some help with figuring out how to configure my xorg.conf for my Arch Linux 64 bit installation on a HP Pavilion dv 5000 laptop so that I can automatically blank my laptop screen when using an external monitor. I have Arch Linux installed along with Ubuntu Feisty. In Ubuntu my external monitor (Viewsonic 1912WB) was not detected at the time of installation but with the native 1280X800 resolution that is good for the laptop takes effect for the external monitor automatically when the external monitor is plugged in. The laptop monitor goes blank when the external monitor is plugged in.
In my Arch Linux installation I have not been able to configure a dual head configuration using the ATI Radeon drivers (fglrx). I have the native 1280X800 resolution set up for the laptop monitor and this resolution takes effect for the external monitor also. However the laptop monitor also continues to function when the external monitor is plugged in. I would like to blank the laptop monitor when using the external monitor.
I am attaching my Arch Linux xorg.conf and the Ubuntu xorg.conf below. Thanks for anyone who can help, I am having a lot of difficulty in figuring out how to set up xorg.conf among all the things that I have had to learn so far in Linux and I am a relative newcomer to the whole thing. I have tried to compare the two xorg.conf files and edit my Arch xorg.conf in accordance with the Ubuntu one but it did not work and I keep getting errors!
I am using XFCE as my Desktop environment.

Xrandr 1.2 provides means for this. But today the only supported configuration is xorg-server-1.3 + xf86-video-intel-2.0. So for Radeon you'll have to wait for drivers that support Randr 1.2.
On my laptop (Thinkpad x60s) that would be:
xrandr --output VGA --auto
xrandr --output LVDS --off

Only black screen on the external monitor with intel-virtual-output

Hello,
I tried to install bumblebee on my Lenovo W520 with this tutorial:
http://www.unixreich.com/blog/2013/linu … ly-solved/
I can activate my external monitor with "intel-virtual-output" and the monitor is switching on. But I can only see a black screen.
In the settings of gnome I can see my external monitor and configure it - but it shows nothing.
Have you any ideas?
Thanks a lot!

Major Problem - LCD Screen Unreadable - Using External Monitor - First Aid

My LCD Screen is cracked, and only 5% of the screen is readable, and I dont have the resources to have it repaired, so have been using an external monitor to do my computing needs.
However, somehting happened to the OS X, and it MUST be repaired according to Disk First Aid. Putting the CD, and I want to force the output of the CD to be put on the external monitor, not the LCD since I can't read it. How can I make it show on the external monitor?

Hi Chef
Insert your System CD an select it as startup volume in "SystemPreferences"/"StartupDisk". Restart your book and close the lid right after the chime. Voilà, your external screen should be main screen now.

Application windows off screen while using external monitor

Hi,
I am using my MacBook frequently with an external monitor attached (lid closed). It happens now, that some applications (e.g.Finder) open windows outside of the screen. What can I do?
This is especially annoying when I want to copy a file and Finder opens the 'Replace/Stop' window and I can't do anything because this windows is outside of the screen (I only see it when pressing F10).
Any ideas?
Gernot

I had this happen last night. I was moving a window and it dissappeared. It was off screen. I could see it wit F10 but that was all. What I did was close the window under file in toolbar. Then I opened a new window under the same command in the toolbar. This brought the new window up in the visible window. Hope this helps.

Screen saver on external monitor malfunction

I am running a mid 2009 MPB with a Fujitsu Siemens 17" DVI monitor in portrait mode. The screen saver produces the worst form of visual noise when it kicks in on the external monitor. Clearing it requires unplugging the monitor from the display port connector. This arrangement has worked well with the previous 2 system upgrades.

Same here also. Second monitor is a Gateway LP2207. Mac Mini late 2009. Installed Mavericks upgrade from 10.8.5.
Second monitor is rotated portrait. First issue was with screen saver, same as OP above. Also Firefox would not start up on main monitor, always started reduced on second. Same issue on startup with Finder. Dragging Finder to second monitor did not always work. . . sometimes it mirrored. Putting the second monitor in Landscape (normal) solved all problems, but is unusable for me. Tried every orientation and all did the same except Landscape (normal) mode.
Will not install Mavericks on my other machines until this is fixed. . . unusable for me!

Pages Full screen view second external monitor

I use a 24" monitor as my primary display when i'm at my desk with my Macbook Pro. Is there anyway to get pages full screen view to display on the external monitor instead of the macbook pro screen?

Jerry
Apple has sort of spoiled the multiple monitor thing, which before OSX used to be a great feature on Macs.
Apple tends to make assumptions about its users, based on whatever it is selling in its latest hardware.
Since so many large screen iMacs have been sold and the external monitor ports have switched numerous times, most users have given up trying to connect multiple monitors and many are probably even unaware it is possible.
It seems this includes the Pages' programmers who have slipped up on this.

PB screen broken-using external monitor now-but can't see hardware test

Hi. I have a 15" PB (1.33GHz) that was recently dropped. The screen was decimated... unusable and can see maybe the far left 1" of the screen... the rest is 100% unusable. So currently I am using a 19" monitor. I was wondering a few things... Is it possible to somehow disable the screen in the computer? I removed it, but the PB nows thinks there are two VGA monitors hooked up (?)... so I put the screen back in and I just sleep it everytime I start up and wake it with an external mouse so I can set my resolution on my external 19" monitor. It's not a huge deal if there's no way to disable it so that I can just remove the thing and the powerbook can be my keyboard
Anyway, I also can not run the hardware test because the F7 key (to mirror) wont work with it. Anyone have an idea what I can do about this? Somehow force the G4 to recognize the external monitor in the hardware test mode?? I suspect some other problems with the G4... such as a bad ram slot (the lower one) - it doesn't recognize any ram sticks that I put in there. I've read that lots of others had this problem... and even though I have applecare, I suspect that Apple won't recognize this since it has been dropped.
Any help is appreciated. Thanks

I assume this is due to the fact that system detects your internal monitor as default one, and that is there where system sends main data. In order to force system send data to the external monitor, get a mouse and physical keyboard, close MB lid, and then press any key on the external keyboard.
when you get there, go to system preferences/display, and manually move the Apple upper bar to the external monitor, then choose mirror; ultimately, set optimal resolution.

Satellite A660-1FM - Max. screen resolution of external monitor

Hi All,
This may be (probably) an easy questions to answer but I have a Satellite A660-1FM and want to use it with my Samsung Syncmaster (forgotten model) external screen. I grabbed an HDMI->DVI-D adapter, and all is well, but here is my question:
The toshiba specs page for my laptop (http://uk.computers.toshiba-europe.com/innovation/product/Satellite-A660-1FM/1096013/toshibaShop/false/) shows an external resolution capability of:
Max Resolution : 2,048 x 1,536
Max Refresh Rate : 100 Hz
Non-interlaced resolution with max refresh rate : 1,920 x 1,200
But I get what I call standard HDMI resolution (not surprising I guess) when connected HDMI->DVI-D to my external monitor. I have previously run this monitor on my desktop at much high resolutions than 1080P, so the monitor is capable.
Just wondered what I'm missing here, or is it a case of the graphics card spec is higher than is possible to output from the laptop ?
Thanks for any help
Andy

Hi,
Thanks for the reply.
As to native resolution of the external monitor - unsure how to find this - but it was running a with a lot higher res when it was connected to my old desktop (which has died and been replaced by this laptop)
R/E the adapter - My Samsung Syncmaster monitor has a DVI-D cable sticking out the back of it, so I needed to connect that to my laptop - either vga-> DVI-D or HDMI-DVI-D to make use of it.
The external monitor is currently running at 1680 x 1050 using the laptop HDMI output -> HDMI-DVI-D adapater -> external monitor.
Before my desktop died, using the same external monitor I was running at 1680 x (guessing a bit here) 2048 ish (really sure I had a greater y res, this 1050 lark is really squishy).. in any case, the Y resolution was much much much better than 1050.
But, according to the specification for this laptop, it can output 2048 x 1536 to an external device (How, the HDMI and VGA outptu cannot go that high right ?)
So, I'm trying to figure out how to get the resolution on the laptop spec onto my external monitior, which has more than handled this resolution before my old gaming desktop died.
Thanks again for the reply - I hope this makes my question clearer.
Cheers
Andy
