Mouse skipping problem when external display connnected

I recently purchased a Macbook, and I connect it to a Dell 3008 display using the mini DisplayPort to dual-link DVI adaptor. My issue is that when the Dell is connected and in use, the mouse pointer skips across the screen when I move it, like something is interrupting the input for a very brief period, and it's being interpolated wrongly when the input comes back.
The problem doesn't occur when the external display is disconnected, and it happens with wired USB, wireless USB and wireless Bluetooth mice.
No adjustment of mouse sensitivity options seems to fix it, and the interruption in the pointer movement seems to happen at semi regular intervals of between 5 and 10 seconds apart, although I can't be 100% sure.
Interestingly, it doesn't happen when I connect a lower resolution external display using the same adaptor. So it only happens at 2560x1600. I'm wondering if it's a problem with a hardware accelerated mouse cursor and the NVIDIA graphics driver.
Anyway, it's a real barrier to me using the Macbook, so hopefully someone has a solution.

Same problem here: wireless MS Laser Mouse 6000, either a samsung or LG external display connected via mini adaptor. Have the MS intellipoint drivers installed. It began to happen about a fortnight ago, and seemed to coincide with the Java update 4/Bluetooth Firmware/ Safari update applied on 24/6. This may have been around the time I changed display preference to 'best performance', so could well be a graphics driver issue?
In my case, it tends to happen in certain spots on the screen, and the likelihood of a skip seems to depends on the speed I'm moving the pointer. Faster = more likely.
It's messing up my tanking in warcraft something terrible.

  • Mouse cursor problem when external display connected

    When my external Apple display is connected to my MacBook Pro (Retina, Mid 2012, 10.10.2) the cursor jumps to a spot on the external display and will not release from it. I move the cursor anywhere and it jumps back to that original spot. Cursor operates normally when the external monitor is not attached. I've used the monitor for a few years with no problem, but this started just recently. I do not use the external monitor daily and I cannot recall doing anything that might have triggered this problem. Any ideas on a fix? Thanks.

    Just an update to close this. Call Apple Support. An advanced support tech walked me through several procedures. Eventually, the problem disappeared after deleting a bunch of plist files and startup items. Which particular file caused the problem we don't know. But problem gone and I will monitor going forward. Hopefully it was a one-time corruption of one of the preference files.

  • Does anyone get the mouse lag with an external display connected via the display port?

    does anyone get the mouse lag with an external display connected via the display port?

    You don't describe the problem in great detail.  Is this the issue you are describing?
    If so, then, "Yes."  I have the same problem.  Note that this isn't a tracking speed problem for me, it's a lag between my hand moving and the pointer moving on the external display.

  • Problems when cinema display attached to PowerBook

    I have a new PowerBook G4 (15" stretch) with OS 10.4.5. I also have a new 20" Apple cinema display. When the display is attached to the PowerBook, I've noticed a host of problems, including: HP LaserJet 1022 (new) prints only about 50% of the time--requires restart to get it working; USB mouse and keyboard attached to the display freeze (although I can still move the pointer with the trackpad on the PowerBook)--requires restart to get them working.
    The printer is plugged directly into the PowerBook's USB port. Nothing else besides the keyboard/mouse are plugged into the display's USB ports.
    I've reset the power manager several times; I don't let the computer go to sleep, although I do let the screens go dark after 15 minutes. I've tried all the usual printer fixes short of resetting the print system.
    The PowerBook and printer seem to work fine w/out the display; the printer works fine on another PowerBook.

    I am experiencing the same problem with a Samsung Aquos 52" connected thorough a Onkyo receiver/amplifier. The connection is DVI to HDMI to Onkyo amplifier and HDMI-HDMI to the TV. The main 23" Cinema Display flashes during turning on an off of both of TV and the amplifier and even when the TV is off and the amplifier is on, unless you restart the computer, it would keep detecting a second display, the only solution so far was to unattach the second display DVI to HDMI cable from the computer. Otherwise, several freezes occur after several flashes of the cinema display and eventually either the dock o the whole screen would freeze...Anyone knows how to avoid this issue? Btw, my id card is NVIDIA GeForce 6600.

  • Problems swapping external displays

    I use my MacBookPro with two external displays (not simultaneously), with the MBP lid shut. I have an Apple 20" cinema dispay in the office and an Acer (can't remember the model) at home. When I take my MBP home and plug it into the Acer the MBP does not properly recognise the external monitor and it just stays black showing the spinning "busy" wheel. The same thing happens when I plug in my Apple display after using the Acer. Sometimes, after about one or two minutes, the display finally appears as it should. Otherwise I have to switch the power supply off and on again to put the MBP to sleep and then wake it again to refresh the screen.
    For two years, I was using the same two monitors with my G4 Powerbook without any problem whatsoever. Does anyone else have this problem? Is there a solution to it?

    Are you sure that the external power supply is properly connected to your MBP? I have occasionaly wondered why my external monitor was not working when connected to laptop with lid shut. Then discovered that it will not work unless the laptop is connected to the external power supply.
    A phone call to a very helpful Apple support technician solved my problem. Apparently the memory needed to be refreshed (or something like that). This was done by rebooting the computer and holding down the following four keys together: AppleAlt+pr.
    You hold down these four keys while the computer boots and release them after the second chime.
    However, as I am not an expert, I have no idea if this is relevant to your issue.

  • Dock Problem with External Display

    I have a macbook hooked up to an external monitor. I made the external display the primary display so it has the menubar and main desktop, but for some reason the dock wont move from the macbook's display, which is the secondary one. I tried restarting the dock, using killall in terminal and restarting, unplugging and replugging, switching to mirroring and back again, and all sorts of other things. My friend has the exact same setup and his works fine; what's going on here? Thanks so much

    I was able to fix this problem on my iMac using your suggestion. It appears that if the external display is arranged to touch either the left or right side of the Mac display, then the two displays are handled as a single desktop. "Left" places the dock on the left side of the combined desktop, "right" places it on the right.
    When I changed the arrangement so that the external display was touching only the top or the bottom of the Mac display, "left" and "right" became the left and right of the Mac display, and my dock is back where I like it.

  • Skipping problems when 2nd audio is added

    I have a problem of movies skipping and long beachball delays when adding transitions etc. if I have two audio tracks installed.
    This even happens on small 15min. movies, but only when I add a second audio track.
    All is normal until I add an audio track and at the point when the track starts to play.
    I did not experience this with iMovie5 or before.
    I have 1gb ram with 18gb free on system disk and working from external 500gb Lacie FW800.
    The two 512mb memory sticks are Apple and system profiler says all is OK.
    I repair permissions twice a week, run Disk Warrier once a week and Tech Tools every two weeks.
    My OSX system is always current.
    I start movies with about 15min. clips & photos. All is well.
    When video is done then I add music from iTunes. When the movie arrives at the music it begins to skip and jump.
    Also, if I add a transition it takes about 12 to 20 seconds to finish while I watch the ball.
    I have cleared the system of all active applications just to see if ram is being used meaning I might need more than 1gb.
    Doesn't matter if I have 0 or 5 active in the background ... same problem
    When I finally get a project done and burn to DVD it plays just fine without skips.

    I need to clarify my initial description when I used the term "skips".
    In reality I am experiencing pauses.
    The movie does not skip to another location, but rather pauses both video and audio during play on iMovie only.
    It takes a very long time to edit just 20 min. due to this problem.
    The burn is just fine.

  • Problem with external displays

    I've an issue with my MBP 15'' Early 2013. Recently I'd the GPU problem and my logic board was replaced. Everything worked fine as usual but I never tried to connect it to an external display.
    When I first connected a projector after the logic board change via a VGA adapter I wan unable to make it work, the computer had one of this two problems:
    Screen goes black and nothing works
    Computer gets too slow and I can't do anything but move the cursor
    Then I tried with a TV via HDMI and everything worked fine. I tried then with an external monitor, another projector and a TV with VGA and nothing worked.
    I searched in internet and most of the people has this problem with both VGA and HDMI. But I didn't found anyone with only the VGA problem.
    I tried resetting the PRAM, changing resolution to all the available ones and nothing worked.
    Before the logic board was replaced the external displays worked great.
    Any idea?
    Thank you!

    Hey, I had something similar happening with my i5 going to a Dell U2410, but my connection was via HDMI. When I got that distortion however I could not recover from it and had to reboot my laptop. I switched to an analog connector & noticed the occasional flicker to black, almost like my cable was loose and got bumped, but it recovered fine each time. I'm testing now with a dvi cable, and so far no issues *knock on wood*. Sorry, no fix, but maybe try a different connection and see if it improves things for you.

  • Update to 10.6.8 colour problems with external display

    I have a mid-2010 13" macbook pro. I use a mini DVI to HDMI adaptor to connect to my Philips LCD TV. It has always worked perfectly including audio. Since update to 10.6.8 (yesterday) there is a colour-cast on the external display that makes it unusable. I have tried a hard reset of the mac with no effect except that the colour cast changed from green to red (strange!).
    Anyone had a similar problem or have any ideas how I could solve it? (no time machine so I can't downgrade unfortunately)

    Though I am using and iMac 27 and not a macbook, I have the similar issues since the 10.6.8 update.
    I too am using the adapter to connect to a Philips 42' LCD.
    You can see my post here: (has a pic of what my TV image now looks like since update.)
    I ended up going back to 10.6.7, not a fix, but no other alternative..
    I used to have this problem a year ago on a PC that happened to have the same ATi Graphics card. I just used the ATI control center and changed a setting to YBR component or something like that in some color settings. But unfortunately we don't have the ATI control panel for mac, least I don't think we have any kind of alternative, but would prolly fix it..

  • Problem Connecting external display

    I Have a MacBook Pro 13" from early 2011, 2.3ghz Core i5, 4Gb RAM, Intel HD Graphics 3000 384mb with OSx 10.7.4 (11E53)
    I'm having some trouble connecting external displays via the ThunderBolt port using a MiniDisplay Port to VGA adapter.
    I have to go the settings -> Screens -> Detect Screens to connect or disconnect any kind of display.

    Not sure.
    All I did was plug my dell monitor's cable into the mini display adapter and boom, it worked.
    Is there any way you can validate that the monitor is working, and/or try this out on another display. Sounds like its either not compatible, or something is defective. (monitor, mini-display adapter, MPB)

  • Fan running when external display is connected

    I have a MacBook Air 13in, mid 2011, 4GB memory, 1.7 GHz (iCore 5), running OS X 18.3.
    With the laptop on, every time I connect an external display (HP LA2205wg) through a miniDisplay to VGA adapter, the fan starts running wild and it is so loud to disturb my work. Yet, I check the activity monitor (All processes) and there does not seem to be any process taking a lot of CPU.
    However, if I swich the MBA off, wait a few seconds for the fan to stop, and then restart the MBA, there is no fan noise. I have to do this every day I get to the office and connect the external display. It's annoying, as I have to reopen the same files etc.
    I have browsed the apple support forums and I have seen similar posts, some dated 2009. Yet no actual fix is suggested in the posts. I am still giving it a shot, hoping I don't need to waste even more time to go to an Apple store. Any help would be greatly appreciated.

    I was experiencing this 100% of the time at work with projectors. I found that once I forced the GPU to NVIDIA in the BIOS... the issue was resolved.
    I'd rather have stability than battery life.

  • Late 2008 MBP problems with external display (kernel panic)

    I have an intermittently recurring kernel panic with a similar signature in the backtrace. In my case it only happens while playing World of Warcraft with an external monitor attached (and even then, only while doing particular things -- not necessarily high load activities, either). I ran a full set of diagnostics (Apple Hardware Test in full mode, and also Tech Tool Deluxe from the Applecare CD) and neither found any problems.
    Anyway, here's my panic log, hoping that somebody will be able to help out. I'll be taking this in for service when I have a couple of days I can spare without my laptop.

  • IMac display getting yellow when external display is attached?

    I have a problem with my IMac (27'' Mid 2010):
    I have an external TV attached via MDP->DVI->HDMI cable. When I turn on the TV, the iMac recognizes it and the iMac display turns blue shortly, then the desktop returns and my TV is ready.
    What I noticed: After the desktop returns, the iMac sometimes suddenly becomes "more yellow". Don't know exactly how to describe it, but I can clearly see how the desktop returns and then suddenly the imac display turns a little yellow, could also be that the display just gets a little darker (although the display brightness is the same as before). it's nothing that really disturbs me, and although I never saw the color return to normal it does (but I think only after rebooting the iMac)
    anything on this? anyone else noticed that?

    Hi nachdenki
    I've used both TV's and Monitors with my iMac over the years and that default iMac Profile has always looked yellow in comparison. Try one of those other sRGB, RGB Profiles or create a new Color Profile for the iMac's display.

  • Primary screen goes dark when external display is added

    Earlier, when I was on Mac Lion, I always used to face problems whenever an external Monitor was added to the Mac through the firewire to VGA converter port.
    Hoping that Mavericks update would give me a respite from the issue, I upgraded my Mac Pro and to my utter shock, the issue has got magnified in mavericks. The primary screen goes completely dark whenever I add the external monitor.
    Any idea how to overcome this issue ?
    Thanks in advance !

    I meant the mini Display Port intead i wrote firewire port.. Hope it doesn't confuse anyone !

  • Resolution problem on external display on Macbook Pro (15-inch, Mid 2010)

    Hi there guys. I recently bought a 23inch Dell Ultrasharp display for my 15inch Macbook pro.
    Max resolution I can get from the screen is 1080p. Althought, I've noticed a weird thing.
    After using my screen for like 2 and a half weeks, when I started my Macbook today the external monitor had a fixed 600x800 resolution which I couldn't change from the display menu on system prefs. Actually, I don't even get any resolution options when I choose the scaled radio button. So I can't do anything.
    I can't reset pram cause obviously command+option+p+r don't work regardless the way I press them (i just get the recovery screen).
    And its the same thing on windows as well (using bootcamp), fixed resolution and no option to change it.
    Thing is that I updated my Macbook's ram from 4 to 8gigs from crucial. At first everything was fine but again after a restart this occured again.
    I opened the case and used one 4gig from crucial and the default 2gig from apple. It worked for the screen and I got back to max resolution.
    Then put the 8gigs again, worked fine for 2.5 weeks and now this again.
    Do you think that this has anything to do with ram or its just Mountain Lion?
    Looking forward for your help!!!
    Many Thanks, Thanos.
    (forgot to mention, I'm using a minidisplay to display port cable)

    Give this a shot.
