Q: Mouse cursor lags with external monitor

Same problem with two Macs: a 15" rMBP mid-2012 and a mid 2012 13" MBP.

Monitor: Dell U2713

Connection: mDP to DP cable (not the Dell cable)

When I go to Menu / Display Settings (or Other Settings), I don't see anything for changing the DisplayPort version. How do I get that?

Same problem here with a 13" rMBP Late 2013 and a Dell U2713H...

Before i bought the U2713H, i got 2 U2713HM and had nor Problems.

Now with the U2713H i have the RGB YPbPr problem (I fixed it with the ruby script) and the lagging Mouse...

A solution for this Problem would be very nice!

Best wishes

I'm also having the mouse lag issue on the following configuration:

MBP Retina 15" Late 2013, using a 30" Apple Cinema Display  connected via the Apple Dual DVI adapter.

I'm using a Magic Mouse and the issue only occurs with the lid closed. Sometimes it's allright, but i don't know why, couldn't figure out the pattern until the next reboot.

Would be great to have a solution to this!

So I plugged in a wired mouse and I'm not experiencing any issues. Both a wireless mouse (with dongle) and Bluetooth mouse are having issues.

I'm suspecting RF interferences... I came across an article last night that talked about how USB3 (of which there is a hub in the Dell U2713HM) can cause RF interferences. I also read that there are issues with Thunderbolt creating interferences on the 2.4GHz frequency (used by wireless devices)... and so when you plug in either a mDP cable you're essentially creating an antenna which amplifies the issue.

Now, I don't get this problem when I use my 23" Dell monitor via the same mDP to DP cable so I don't think that's what is creating the issue. This is so confusing and is looking more and more like a witch hunt and voodoo to me.

So for the time being, I'm using my wired mouse.

Same problem with a macbook air mid 2013 13", i5, HD5000, connected to a Dell U2713H. Cursor jumps, but as sendaal says sometimes it's allright, very annoying. I had my macbook checked in the store but they couldn't find anything.

I tried a Logitech mouse, apples usb mouse, and the magic mouse with bluetooth connection, always the same problem.

I am using the original dell mDP to DP cable. At the store I tried the apple thunderbolt display which seems not to have the problem. I am wondering if a mDP to mDP cable could be a solution.

The problem with the colour mode can be fixed with the EDID override file. Works just fine.

A solution would be great, don't want to get rid of the dell display.

guys, you are right.

when I change the DDC/CI settings on the display, it's immediatly gone (maybe it's any setting). However, if you turn of the monitor, you have to set it again.

Whatever the reason.

Same problem here, DELL U2713H with this fix applied - http://embdev.net/topic/284710

My workaround is amusing - if you go into the menu on the monitor, and use the up/down keys on the monitor to go through the items, it fixes it.  However, you need to do that every time you turn on the monitor/reset the computer.

Note I am not actually changing any settings, just scrolling through them.

Crazy.  All of our Mac Airs 2013 model show this problem and work with this solution.

Ridiculous, actually.

So all of you sound incredibly more knowledgeable in computers than I am..so I apologize if this is a stupid comment. But I had the same issue with my mouse/keyboard lagging on my external monitor (acer I found buried away in my basement).  I also was unable to view streamed videos because they would skip. However one night while I was trying to fix the problem I remembered that I changed my desktop background settings (on my monitor) to slide through a bunch of photos I have (every 5 seconds)…I guess it kind of makes sense why it worked, but I changed it to just show one picture all the time and it fixed the problem immediately. I don’t have any mouse lag or typing lag any more and the videos stream fine…not sure if this helps.

Again this conversation is way out of my league but I figured I say something

Just to inform u all, The latest update to OSX (10.9.2) didn't fix our issue  

Displayport output still make cursor skip. HDMI output to my 21:9 (2560x1080) monitor still limited to 1080P

resolution.....

Totally disappointed!!!!!

Unfortunatly I don't even expect Apple to fix this anymore. The sad thing is though, this makes it impossibile for me to use products i've grown to depend on for years.

Do you guys attach the external monitors directly to yout macs or do you use any kind of adapters? I was curious weather getting a monitor with displayport would alleviate the issue... as opposed to my dual-dvi adapter -> 30" ACD...

so so frustrating!

Yes, I think it is clear that Apple won't fix the issue anytime soon. As to your question, I go directly from miniDP to DP and have the problem.

Thank you!

My current workaround is to open the lid whenever this happenes, but most apps, especially Adobe ones are really bad at managing dual displays.

I'm using a mDP to DP cable, directly into a DisplayPort and am reproducing the issue.  You know, I bought a MacBook Pro Retina because I wanted a high-end machine that "just worked".  But I've had WAY more problems with it than I've ever had with any PC I've used.  All my PC's work with this monitor flawlessly, regardless of DVI versus DisplayPort.  Only my $2300 rMBP has problems.  I've spent 20 years in the PC world (and I'm still largely in it) but I'd expected Macs to have fewer problems.  Out of the box, I can't even connect this to my $1200 monitor. That's pretty lousy, and definitely not what I'd expected from Apple.

Symptom : Lagging & Unstable Mouse

Model : MacBookPro; 13" brand new as of jan 2014

OS : Mavericks 10.9.1

Monitors : 2 x Dell U3014 ; both setup for DP 1.2

each monitor with dp -> DP cable to individual dp ports on Mac. ( not daisy chained )

Mouse : generic PC USB ( tow different ones tried )

Reading another post in here on this subject I tried something.....

Went to to single U3014 with laptop closed and set Dell - DP 1.1      :      That worked

Plugged in second U3014 and switched it to DP 1.1                          :      That worked

Open Laptop with both monitors enabled and hooked up as DP 1.1 :      That worked

Switched both Dells back to DP 1.2                                                    : Still worked .. go figure

Shutdown & Reboot  Laptop open and both monitors attached in DP 1.2 mode  : That worked and it is stable.

Did not expect the last two lines , but I am not going to agrue with the result, my guess though is that it will fail again in a day or two and the mystery will show itslef again

OK... so after a day, the mouse went unstable three more times.

The trigger to fail ( for me at least ) is often when I remove and replace the LTop onto the monitor cables. 
I.E. head to a meeting with the LYop and return and hook up the monitors to the tow DP ports.

One common fix was to change either of the displays from 1.2 -> 1.2 OR 1.2 -> 1.1

No reboot restart or reboot required.

Go figure
