Dell 2005FPW causing mouse lag?

I recently purchased the Dell 2005FPW 20.5"
widescreen LCD and am running it at 1600x1050. I have
noticed a slight amount of mouse lag since swapping
monitors (was using a Viewsonic P95f+ CRT). It's
apparent enough enough to be annoying when trying to
click on small spaces, such as close window, etc.
This was not so with the CRT.
I have a Dual 2Ghz Power Mac G5 with 2GB of RAM, and
the ATI Radeon 9650 video card (256MB VRAM). Seems
like the video card should handle this display with
no problems. Anyone else experience this issue and
know how to correct it?
I hooked the Viewsonic CRT and the problem went away,
so I know it's related to the Dell display. Please
advise
LCDs often have a 25 millisecond, or longer, response time, mostly in the turning off (going to black). People complain about this causing fast moving objects to leaving trails. Instead using a faster LCD panel, some companies fix this by processing the signal before it gets to the LCD. This involves anticipating the response time of the LCD and adjusting the signal to compensate for it. LCDs are slower turning off so they want to get turn-off signals there faster than turn-on signal. The only way to do this is to delay turn-on signals. This is fine for watching video with fast moving objects (as long as you delay the sound by the same amount), but causes problems positioning a cursor quickly, or playing some video games.

Macbook Pro Wi-Fi causes mouse lag for Logitech MX Revolution

I just got the new 15" Macbook Pro 2.4ghz on Tuesday, October 28th. Yesterday, I tried using my Logitech MX Revolution mouse with it only to discover that it was nearly unusable. The cursor would lag terribly, sometimes sticking in one spot for several seconds and it was often not registering mouse clicks or scrolling. I tried it on my old Powerbook G4 that I had been using it on without issue for over a year. It had the same issue all of a sudden so I tried it on my co-workers 2007 Macbook Pro, he works across the office from me, and the mouse worked perfectly again. Next, I brought my old Powerbook over to his desk to see if there was some interference at my desk, and sure enough, it worked on that Powerbook again. So I then tried disabling the wifi on my new mac and lo and behold, the mouse worked perfectly on that machine.
I've tried switching the channel on our office router (it's a 1TB Time Capsule) a few times and that would help for a few seconds, and then the mouse lag would begin again. I doubt there's a way to change the frequency on the Macbook's wifi card, but if there is let me know. Beyond that, I'm not sure what to do. I will be a little upset if this mouse (which cost me $100) is obsolete because of my Macbook upgrade. There must be a way to get it working again. Ideas? Thanks!

Hi,
I use a new 2,53ghz Macbook Pro togeter with a MX Revolution mouse. I use 2 Airport Extreme base stations in my w-lan and until now see no issues using the mouse.
Do you have the chance to try and check if the same promlem occuors when using an other MX Revolution / receiver combo , maybe there is an issue there.

OSX update 10.10.2 causes mouse to jump around and text to be highlighted randomly in Dreamweaver CC 2014

OSX update 10.10.2 causes mouse to jump around and text to be highlighted randomly in Dreamweaver CC. When trying to click on a specific line of code in a js file the cursor ends up in a different place in the script and several lines of code highlighted. Clicking again jumps the mouse to a different position and even more lines of code highlighted and some characters rearranged, breaking the lines of code. Very frustrating.

Preran,
I am having the same issue. I have a MBP connected to 2 x Dell 27" monitors over Mini DisplayPort to HDMI cables. Once I updated to OS X 10.10.2 this cursor highlight/jumping around issue only occurs on the connected monitors. If I move the program to the main laptop display the issue goes away. It does not require me to restart the program or the machine to make it work correctly. One way I am able to identify the issue is if I go to the line numbers in code like I wanted to select multiple lines - in the one that works correctly, the cursor turns into a white version where the tip of the cursor points to the right. When it is wrong, the cursor stays black and will only have the tip point to the left. Its just another way I identified if it was working cause I tried uninstalling DW and reinstalling - didn't work. Reset preferences as you discussed - no go. And I used other editors like IntelliJ and Adobe Edge Code - all of which work fine and don't display this issue.
I tried the preferences reset you suggest and it doesn't work. I have another machine with OS X 10.10.1 on it and this issue is not there on any monitor. Any help with this ASAP as it pretty much stops you from being able to do any editing especially with longer pages as it consistently wants to page up when you select anything and if you then click again in another area it tries to move the highlighted code to that new spot.
Update: I have a USB Microsoft Arch touch mouse connected (always worked just fine). When I go to place my cursor at some point in the code it causes the highlight flicker. If I switch over and use the built in trackpad, then I can place the cursor without the highlight issue. When trying to select multiple lines or sections of code, that still see's the highlight, page up and move of code issues regardless of input type.

Bluetooth mouse lag

So here is the situation: I have a Macbook Pro (early 2009 model) with an Apple wireless keyboard and a Logitech V270 bluetooth mouse. Recently, I've been experiencing mouse lag (to the point where I can hardly even use the mouse anymore). The lag is intermittent, but is there more often than not. I've been pounding my head searching for a solution to this problem, and after scouring forums and trying different solutions, I gave up completely on finding a remedy. But before I threw in the towel, I tried one more thing: I disabled the bluetooth on the Apple keyboard and tested the mouse. To my amazement, it worked perfectly! I re-enabled the keyboard, and sure enough the lag returned. Now that I have isolated the cause of the problem, I was wondering if anyone had a solution that would allow me to continue using both my keyboard and mouse? (I have my MacBook on a stand, so it would be impractical to not have one or the other).
Any help here would be greatly appreciated!

Update:
Upgraded to 10.6.5 - No difference..
Changed/tried all wifi channels - No change to problem.
Tried a Mac Mouse - slightly less effect but still unusable.
Tried a USB BT dongle type mouse (no using internal BT AP) - Same issue
Tried on a friends Wireless Network - Problem only slightly evident - to be expected as this was a slow network at about 1.9MB/s, a transfer speed that does not show the problem.
Tried using a Netgear wireless intBT mouse router - Problem is only slightly evident on Mac Mighty Mouse, worse on Logitech, evident slightly on ext BT mouse.
With the Wireless nw running a transfer at 3MB/s, this Network speed drops down to a very slow speed when the "Set up Bluetooth Device" utility is initiated.
So given that this issue is also experienced by MacBook owners when using BT mouse while doing a File transfer via USB external HDD, or Time Machine. My conclutions are either:
1.
The USB ports, BT chipsset and Airport Chipset are all using the same data bus in the Macbook.
This data bus is not capable of running a high speed, contiguous data transfer in a single direction AND transfer BT wireless data at the same time. Apple Architects may be able to work around this issue by appling higher priority to BT data transfer tasks (Mouse), as it does when the "Set up Bluetooth Device" utility is running.
or
2. The BT wireless hardare is eisily susseptable to RF interference. This dont explain USB drive influences however.
My best bet is to log a Hardware repair request with Apple, as this is indeed a Hardware issue.

Flash Player performance slowness and mouse lag

I've been having this problem for a while. I already did the usual google searching and didn't find anything useful. Specifically its games I play on kongregate and other sites. When they are using flash player I tend to get poor performance. If it uses a mouse cursor the mouse lags/skips across the flash player window, when it leaves the flash player area the lag doesn't occur. I dont have problems when I'm in games or general responsiveness of the system, I've plenty of space, low processor utilization, low memory utilization, etc etc.
I have windows 8.1, IE11, the latest flash player, video and system drivers are all the latest and greatest. I've found articles suggesting to turn on/off hardware/software gpu acceleration in IE, it also occurs in Firefox.
ideas?

Thanks for the suggestion. I'll try this. Which browser (and version) are you using? My question was as much about the performance of Flash player in a 64 bit environment as it was about the video playback hardware performance. I'm sceptical of the shared video memory and throughput performance of the Intel-based 4500HD graphics package in my laptop. I'm worried that it might not be sufficient for full-screen flash video playback, or for large external displays, so I'm trying to explain the poor platback performance that I'm seeing, and hopefully show that it's not the fault of the video HW.
Which video HW do you have in your dell?
Thanks

Mouse Lag and poor performance. Video Card or Power?

Not specifically a FCP question but related. I recently purchased a new rig. Here are the specs.
2 X 2.93Ghz 6 Core/16GB RAM/ ATI Radeon 5870 video card.
I am having very odd mouse lag problems that are quite annoying. I am also having issues with playing sequences in unlimited RT. A guy in our office can play back better with an quad core. In regards to the mouse problem I have tried several different mouse and keyboard issues including a Wacom tablet and I get the same poor results.
Some people say it could be my video card and some say it could be a dirty power issue. I took the rig back to the store and the tech geek in the back said it worked fine for him but when I showed up with the keyboard and mouse to test it he had boxed up the computer and gone home.
Here is a clip of the screen and the weird jumpy jittery problem I am having.
http://pdvpro.com/stupid_mac/
You can see the mouse and the window I am dragging freeze for a second even though I am mousing smoothly and continuously. The mouse and keyboard and Wacom tablet work perfectly on my old Dual Core.
Any ideas?

According to your video, it's happening in Finder, not just FCP,
so it must be something systemwide.
Is there something running in the background, like Spotlight indexing?
System Preferences > Spotlight > Privacy add your disks to be excluded.
Anything else running in the background?
Anything weird connected to your USB?
Also turn off your Airport or any network connection and repeat the test.

Win7 Client got mouse lag with roaming profiles

Hello!
I got several clients, served by a Win2008r2 AD. Those clients supposed to have roaming profiles. Now if I enable them, there is a mouse lag, like the pointer is always in delay, also if you click, you notice that it takes longer than
normal.
If I logon with a local profile, none of that problem occurs.
No event logs
No change when use a fresh/new profile either
No rootkit/virus etc.
No overheating the hardware etc.
Does someone have an idea where I could look?
How I could diagnose a problem if I have GPO's interfering?
Thanks
Roger

Hi,
are your users potentially running multiple different OS versions?
Do you use custom mouse drivers on some of your hardware?
A possibility I see is mouse configuration information in the userprofile. if that information does not match what is expected, such issues can occur.
If the issue occurs, verify the mouse settings from control panel.

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?
https://discussions.apple.com/thread/4398076?start=0&tstart=0
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.

Why do everytime i minimize something my mouse lags (delay move)?

I've got a problem here!
First i started off using windows 7 ,then I've changed my theme into windows classic, then i changed it back to windows 7 and now everytime i click on a minimize button my mouse lags. I'm using a razer deathadder, but i don't think thats the problem because i've used it before i changed it to windows classic and while i was in windows classic ( no mouse lag while i was on windows classic and windows 7 before that) but now my mouse is lagging wen im back on windows 7.

Anyone knows how to fix this??

Updating the graphic driver might help... please download and update the latest driver for your graphics card

GMA950 and Dell 2005FPW

Will the Dell 2005FPW be supported at 1680 x 1050 by the GMA950 graphics?

It has to. Dell 2005FWP is the same as Apple Cinema 20"except a few details. The only issue is if Apple chose to exclude DELL id during hardware recognition procedures, but I do not belive tApple engineers would ever made it as selective. Apple does not seem to have intentions to avoid support of most models of displays within electrical or resolution limits.
I do not belive that Apple would stop optimal resolution support for its own Cinema display. Dell and Apple units are build on the same LCD panel... probably by the same manufacturer.
I will find out in two days as my new Mac Mini comes home on March 1 and I already run 2005FWP with other systems. I will also find out something about switching all peripherals between Mac Mini, Windows and Linux.

Magic mouse lags bluetooth audio

Magic mouse lags bluetooth audio with cracking and pitch shift.
After Magic mouse disconnected, then bluetooth speakers sounds perfect.
Please help!!!

I have this same issue, but opposite. My audio in my bluetooth headphones sounds great, but when they are connected my bluetooth mouse (microsoft 5000) is all over the place.
What's the deal. I didn't know my $2000 mac would be so inferior to my $800 pc in this regards (otherwise very happy with switch to mac)

Mouse lags

My apologies if this has been discussed elsewhere. I have looked but to no avail.
I am using the 2011 new iMac i5 with 12 GB of RAM and I have tried a wired A4tech Mouse (heavy lag) and a Genius wireless mouse.
I am using Windows 7 via boot camp. I only experience mouse lags during gaming. The mouse works fine for about 5 minutes but then the cursor starts lagging.
The magic mouse works fine though and doesnt lag.
My iMac is connected to the internet by lan.
Any advice would be greatly appreciated.
Thanks.

Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?

Bluetooth mouse lags often. Maybe conflicts with Wi-Fi, using same band?

My Bluetooth mouse, a Logitech v470 laser mouse, lags often on my MacBook Pro. I'm thinking that maybe it could be conflicting with my Wi-Fi, which is also enabled, and which uses the same band as Bluetooth – 2.4 GHz? Could this be the reason for the lag? My Wi-Fi also drops sometimes, so I don't know if the two are related or not.
Could someone care to shed some light on this? I've read several other threads on these forums and noticed that other people are having similar issues, and would greatly appreciate a response.
Thanks in advance!

Yes, they can interfere. Try using a lower channel number on Wifi or switch to the 5Ghz channel if possible.

Dell 2005FPW, pivoted, with Apple 20" Cinema?

Is anyone using this configuration? I'm thinking of getting the Dell to use in portrait mode with the Apple 20" Cinema. Any advice would be ppreciated.
G5 2GHz Mac OS X (10.3.9) GeForce FX 5200, Apple 20" Cinema display

Thanks again to all. The Dell 2005FPW does work splendidly with the Radeon 9600. I have them probably permanently set up with the Dell in portrait mode to the right of the Apple display. Each can easily have its resolution changed independently, although I don't think quite the same resolutions are available that were with the nVidia card. (not a big deal to me.) The Dell can pretty comfortably display a full orchestral score at a readable resoluton. It's also easy to disable one monitor with software if you only want one on, useful to me because both are behind a big plexiglass music desk, and the power buttons are inconvenient to reach.
I spent some time with Applecare before it was revealed (to several Applecare folks as well as me) that the power supply for the G5 is 600W, more than ample to power the Radeon, which acoording to THEIR tech support requires 250W. The line in the G5 manual that "Combined maximum power consumption by the AGP and PCI cards is 90W" is still a mystery to me and those several Applecare people, and doesn't interest the smarmy and unhelpful Radeon tech person. I don't see how this all adds up, but nothing has melted.
Thanks again, folks.

Mouse lags after changing Harddrive

After i installed my SSD in my Mac Mini and restored the Operation System (Mountain Lion) from my Time Machine Backup i encounter a very strange mouse lag. When i move the mouse, the cursor jumps almost every 3 seconds.
I've tried already a different mouse and different USB Ports. Same problem.
I rebootet the system and checked Activity Monitor for weird Process behaviour, but everything seems fine.
Any suggestions?

I fixed the lagging issue now. It seemed to be an issue with the external monitor. After unplugging the HDMI cabel the lagging stopped.
