Q: Mouse cursor lags with external monitor

hello,

i have just purchased a dell u2913wm monitor with a native resolution of 2560x1080. when connected to my macbook air (with mountain lion) using a mini displayport cable my cursor starts lagging on both screens. basically, when i move the mouse along a line on my desk the cursor results in a very erratic trajectory. this occurs when using a usb mouse and with the integrated trackpad. if the monitor is turned off or unplugged the mouse is smooth again. .

 

a similar problem was reported a few years ago but somehow the thread is just archived ( https://discussions.apple.com/thread/1965949?start=0&tstart=0 ).

also, i had trouble with the monitor that osx recognised it as ypbpr, so i had to force it to treat it as rgb device, because otherwise the image was unsharp.

 

on my macbook (mid 2010) running mavericks the cursor is smooth, so the monitor and the cable are apparently not faulty.

MacBook Air, OS X Mountain Lion (10.8.5)

    Same problem here with a MacBook Pro (Retina, 13-inch, Mid 2014), OS X Yosemite 10.10.1

     

    At work I try to use a setup with a DELL U2412M and also tried with a Samsung Syncmaster 24" both connected via Thunderbolt -> MDP -> DVI

    I reported the issue to Apple via their feedback form and linked to this thread. But I have little hope that this issue will be fixed once and for all in the near future.

    I have Retina MacBook Pro 13' and LG-34UM95-P ultra-wide display with Thunderbolt connector. My Logitech Anywhere MX is terrible, laggy, can not be used when an external display is connected. I use the Magic Trackpad with no problem, no lag, but I can't use all day, because it's pain in my hand. Yes I have tried a Magic Mouse, but it's not ergonomic. I hope to improve the lag, but I doubt it. If I switch to Windows, if mouse lag doesn't change. This is so horrible. I'm not an happy Apple user... Do you have any tips that will help me? Thanks!

    A few things to clarify:

     

    • Does the logitech lag on both OS X and Windows (run via Bootcamp or VM?) ?
    • What happens if you switch off bluetooth?
    • Is the macbook opened or closed when the lag occurs?
    • Have you tried a cabled usb mouse?
    • Do you mean by lag that the cursor is not moving more than a second or less?
    • Can you test with the monitor connected via a MiniDP to DVI cable or anything like that?
    • MagicMouse is working without problem?
    • Do you have some sort of other bluetooth mouse at hand to try out?

    Does the logitech lag on both OS X and Windows (run via Bootcamp or VM?) ?

    - OS X only

    What happens if you switch off bluetooth?

    - Bluetooth can't be turned off, I have Apple BT keyboard.

    Is the macbook opened or closed when the lag occurs?

    - Closed. I tried to open. Same result.

    Have you tried a cabled usb mouse?

    - Yes, but i hate wired mouse, and it is also laggy.

    Do you mean by lag that the cursor is not moving more than a second or less?

    - Sometimes I miss the cursor, but it appears away. I can't write well, but it's unpredictable. I move the mouse steady rate, but falters cursor does not follow exactly.

    Can you test with the monitor connected via a MiniDP to DVI cable or anything like that?

    - Only Thunderbolt cable. No other for me.

    MagicMouse is working without problem?

    - Yes, but not ergonomic. I sold.

    Do you have some sort of other bluetooth mouse at hand to try out?

    - Yes, Logitech M555b. This is even worse. Useless.

    I use these, because Logitech Control Center app is not available in Yosemite:

    SmoothMouse, Scroll Reverser, BetterTouchTool, BetterSnapTool

    I turned off everything, but doesn't help.

    Some things you can test:

    • Try with the macbook opened with a fresh restart of OSX.
    • Can you try with bluetooth off just for testing the mouse?
    • Is just the mouse lagging or is the whole picture freezing? Try with a video playing so you can see if the whole screen is freezing.

    The exact same as with the wireless?

    Restarted. MacBook open, but it's still laggy.

    BT off, no change.

    The display doesn't freeze, just mouse cursor is laggy.

     

    No, this is an old Microsoft Intelli mouse, and a Logitech RX250. Both are s...t.

     

    Trackpad works fine, but uncomfortable. I have a pain in my hand.

     

    There are times when everything is going well, but soon coming mouse lag. I don't know why... This is not the mouse problem, Apple's software is not good. I have used Windows. Any mouse is perfect, no lag, no delay. I'm tired...

    This is definitely an issue that appears when an external monitor is connected. And it is an OS X fault.. really annoying. Did you verify if it is only the mouse cursor or the whole screen that is freezing/lagging?

    Only the mouse. I watch a lot of movies, there is no problem.

    Yes, it is annoying. I don't like my Mac anymore...

    My Retina MacBook Pro 13' and LG 34UM95-P and Logitech mouse is very bad to use. If I buy a new MacMini or Mac Pro will not be a problem for LG Display and Logitech mouse? It's a lot of money and don't want to problem with lagy cursor again ...

    Thank you very much for your support!

    :-)

    Hey guys,

     

    I´m having the same problem here but also a fix (at least it works for me)

     

    Setup: MBA 2014, i7, 8GB, 256GB; LG Flatron 22EA63, Magic Mouse, Steelseries Sensei Raw.

     

    For me unplugging the external display gets rid of all mouse lag, then when i plug in the display again the lag stays away.

    So what I recommend is plugging in the display after the mouse is connected.

     

    cheers

    Hey guys,

     

    I'm having the same issue.

     

    I'm running mid-2014 MBP 13", the 2.6G/8G model, with 10.10.2. External display is ViewSonic VA2431wm.

     

    I'm using miniDSP-HDMI cable. Didn't try to use HDMI-HDMI cable.

     

    Issue occurs both for trackpad and apple magic mouse.

     

    Unlike Hannes0586, the guy before me, lag not disappear no matter plugging in the display before or after connecting the mouse. I think the order doesn't matter because the trackpad also has the same issue.

     

    The put-mac-in-sleep-for-10-second solution in page 1 seems work for me. But I do hope Apple can solve this issue completely.

    I tested again. Wired mouse with no problem, but any wireless mouse is terrible. I'm angry. Grrr! I don't like cable on my table...

    I found this thread when searching Google about my own mouse skipping problems. I found a solution that seems to work on my setup, thought I'd share it here in case anyone else found value in it.

     

    I have a MacBook Pro (Retina, 13-inch, Late 2012) with Intel HD 4000 1024 MB graphics and a 27" Apple Cinema Display. With a wired Logitech USB mouse plugged in either through the display or in the laptop's own USB ports I observed the skipping issue. Same for using a bluetooth Magic Mouse. Super wierd.

     

    The way that I have resolved the issue is that I plugged the Thunderbolt cable into the port nearest the power adapter.

     

    I realize this sounds a little weird, and I have no idea why it would work, but it does for me. Good luck.
