D3100 docking station - mouse and keyboard is very laggy, high CPU usage

Q: D3100 docking station - mouse and keyboard is very laggy, high CPU usage

I got dell laitude 7270 model and recently purchased the D3100 (DisplayLink) docking station. I believe it used the USB 3.0 to connect the laptop to the dock
I got two external Dell screens (normal wide screen with max 1920x1286 resolution not 4K screen)

We experience laggy, delay when using mouse and keyboard. It does not matter if cord/cordless or plug in directly to laptop or to docking station

Using laptop by itself dont have that problem

It prove to me the limitation of USB 3.0 bandwidth create this issue

Not too sure if Dell is aware of it and make any improvement. I have chat with ProSupport but so far only recommendation is to upgrade laptop to latest firmware

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)


My belkin soho kvm F1DS104J when just connecting the usb cable from the kvm only to the dock only the keyboard works.  The mouse seems to work for a split second and then stops? If I connect the usb cable from the KVM directly to the laptop both the keyboard and mouse work?

hey out there, i'm trying to find out if the d3100 docking station work with any machine with usb 3?
i want to be able to have my two monitors, keyboard and mouse plugged into the docking station and then plug it into my xps 15 laptop but i want my partner to be able to use the desktop machine we have while the laptop is away.
if the d3100 supports any machine with usb 3, i can use it as a docking station for both my laptop and desktop ;)

I updated my working station coming from another laptop and had 2 monitors connected (in hdmi and usb->vga adapter). Autodesk 3d applications Revit, 3dsmax all worked fine in all monitors, the usb dongle was using laptop's CPU/GPU to show image.
With new laptop I got D3100 docking station (as usb->vga adapter has some flickering on 5510) to connect my monitors. But mentioned applications do not work at all on that, anything considering 3d runs awfully slow. Using the usb->vga dongle it works well beside flickering.
Is it how it supposed to be with D3100? Can it be forced to use laptop's GPU for showing image (like the cheap usb->vga/hdmi adapters)? This docking station doesn't make any sense now.

I have a Latitude E7470, connected to my D3100 dock via USB3. I have a Dell E2317H Monitor connected to the D3100 via DP. Works fine having it setup as my main display and extending to my laptop. The problem is the Laptop and or the D3100 are not recognizing the 2 other E2317H Monitors that are connected to the 2 HDMI ports with HDMI to DP cables. The OS kind of detects the monitors but will not push video to them. I have tried every which way I can think of with the OS and the Display Link software and have no joy. Any help would be greatly appreciated.

I purchased a Dell D3100 for my non-Dell laptop in 2016. Initially, I was able to connect two 24" LG tv/monitors to my laptop via HDMI. I'm not sure if there's an issue with a Windows 10 update (I have the latest DisplayLink drivers installed), but my laptop will now recognise the external hard drives attached to the dock via USB, but will not recognise the monitors attached or the dock itself.
Is there something I'm missing?
Any help would be immensely appreciated!

I just purchased a new XPS laptop and the D3100 docking station. I need to connect a Focusrite Saffire Pro 14 that has a 6 pin Firewire 400 out.
Should I connect directly to the XPS via the Thunderbolt port using the Apple sold Thunderbolt to FIrewire adapter?
Is there a way for me to connect with the dock via the Thunderbolt compatible USB 3 ports?
Any help is appreciated, thanks!

So it seems that this new dell docking station doesn't seem to work well with the new XPS 13 (2015 model) that came with Windows 8.1 OS.  I had ordered 10 for our users for the hdmi output and potential 4k for monitors but it seems after hours with Dell tech support it seems that they can't get no close to resolving the problem.
The issue is that after installing the docking station software.   All but two devices are left under Device Manager as devices with no drivers (Dell Gigabit Ethernet, Dell USB Audio).  I thought I could look live without those two devices but after plugging in a Dell 4K monitor i get no out from my XPS 13 laptop.  
I tried downloading the D3100 drivers from the Dell website but it's the same install that is available from the cd-rom install and re-install doesn't update the drivers.
If someone has found any resolution to this it would be quite helpful.

A:D3100 Docking station for Windows 8.1 (XPS13 2015)

I had this problem with a Latitude 7350 2 in 1 and the D3100 dock.  I'm running Windows 10.  This problem was driving me crazy

I went into C:\Program Files\DisplayLink Core Software.  Go into the Audio Driver Folder and the CdcNcmDriver folders and find the files with a .inf extension.   Right click on them and choose Install.
That should load the drivers you need for both items.  That's what finally worked for me.
If you can't see the extensions, you need to go into Control Panel - File Explorer options - View tab and uncheck the box next to Hide Extensions of known file types.

During an office move, I lost a power supply for a D3100 docking station / port replicator. I know that I need a 19.5V 65W power supply, however there is several adapters with those specs listed on the website and the compatibility is also only listed for laptops (not to mention some review saying they followed the compatibility lists provided and still ended up with a wrong adapter).I would like some help knowing exactly which product I need to get the replace my lost power supply.

I just received my Latitude 7370 along with a D3100 docking station.
According this article: I should be able to get 2560x1440 on HDMI, I'm stuck at 2560x1080
Running 2 external monitors ( LG-34UC87C-B)
Display port @ 3440x1440 (this works fine for me)
HDMI 1 @ 2560x1440 ( I cannot reach this, I can only get 2560x1080..?)
HDM 2 is not used
Running the HDMI @ 2560x1080 just looks horrible, how can I achive the 2560x1440 that this device states it can handle?
If the D3100 cannot handle what I require does Dell make a Docking station for the 7370 that will handle idealy 3440x1440 x2? either HDMI or DisplayPort.

I have a nearly new Dell Inspiron  15 7000-series laptop. I also have a D3100 USB3 docking station. The dock has a monitor, speakers, mouse, keyboard, and disk drive attached. All was working fine for weeks. Just a few days ago, the speakers stopped working. Sound is now coming out of the laptop speakers even when the laptop is docked. In the Device Manager, when it is docked, there is a USB Audio device that has an exclamation mark on it. (E.g. isn't working.) I've tried updated the audio driver through the Dell support site. No improvement. I then found the latest driver on dell.com for the D3100 dock. I tried installing it, but it was refused, saying that the existing driver was up to date.
The speakers work fine when plugged directly into the laptop audio jack. E.g. there is no problem with the speaker hardware.
Any ideas how I can get the dock audio working again

Hello Together
Have Docking Station D3100 connected via USB 3.0 to my laptop. 
I recognized many times that when i touch or little bit even Move my dock station, or touch any wire connect to dock station- the second monitor immediately disappeared. And in some seconds or minutes it switched again.
it seems to me that docking station reacts to outer static electricity.
Does anybody has this issue?

Does anybody has this issue?

              We bought Dell docking stations D3100 to go with our Dell Latitude E7450.
I’m trying to configure the laptop for when the user disconnect it from the docking station, it automatically connect back to the network Wi-Fi.
Adapter Switching work great if I use the Ethernet adapter on the laptop itself. Once I disconnect the Network cable, it looks for the Wi-Fi and connects to it with no issue.
If I connect the network cable to the docking station, once I remove the connection from the docking to the laptop(usb3), I lose the wired network and it’s not even looking for the Wi-Fi.
I did configure the Dell gigabyte adapter on the docking station to be the first priority over the Wi-Fi just like I did for the laptop network adapter.
I updated the bios, firmware and drivers.
I also looked at the bios power management: Wireless Radio Control settings
Both local area network connections are above the Wireless one (priority)
Both Local area network adapter metric are set to 10 (only 1 is in use, both are set for testing purpose) while the wireless adapter metric is set to 9999.
As anyone had this issue or was able to get this working? Am I missing something ?

Hi, guys,I have next setup: Dell Inspiron 7567 laptop, Dell D3100 docking station and LG Flatron e2360 monitor. And I have a problem with it.The problem is related to video cards installed on the laptop. The laptop is equipped with Intel HD Graphics 630 and NVIDIA GeForce GTX 1050 Ti. And the problem is that laptop/docking station/whatever doesn't use NVIDIA card to display the picture on the second monitor. So, if I run game or movie on second monitor it's displayed using only Intel card. Problem doesn't appear if I connect everything directly into the laptop(I guess, it's a docking station problem). How to solve that problem?

I have recently purchased a 5510 and a D3100 docking station. Used primarily for solidworks and rhino. My issue is that besides 4k and older applications being terrible bedmates is that the docking station stops the quadro so everything is running software open gl. I understand the new thunderbolt dock DB16 has some additional graphics capabilities but they are by no means a quadro solution, nor it is recognized by solidworks. 
This is hugely problematic. Is there a method to remedy this? Attempting to access the quadro settings while plugged into the docking station results in windows stating that the hardware is not available.

As the subject line implies. I have a xps13 running windows 10 and I just purchased a d3100 docking station.
I assumed I would be able to run 2 monitors and the built-in digital display (3 total screens) all autonomously. 
I downloaded the drivers and then plugged into the docking station and to my dismay, the monitors are not working as I expected. 
I currently have just 1 27' dell monitor connected through the display port. (I need a dvi cable before I can connect the second monitor.)
The Intel HD graphics control panel doesn't recognize that I have multiple monitors. It only recognizes the built-in display. The system display settings do allow my to go into extended desktop mode but it's very clumsy, it won't let me decide which monitor is primary, etc...  
Am I doing something wrong?

I have the Inspiron 5748 and the D3100 docking station.
Windows 10 creator update installed, all latest updates drivers etc.
DisplayLink Manager v8.0.762.0

I have an external HDMI monitor, the problem is simple.
When the monitor is plugged in the docking station anything using that HDMI screen DOES NOT use the NVIDIA GPU, it uses the on-board Intel chip.
When connecting the monitor directly to the laptop all applications on the external monitor use the NVIDIA GPU (I have this as default in the NVIDIA control panel)

Please advise on how I can get the D3100 to work with the NVIDIA GPU.

Many thanks.

Operation is seamless for the KV of KVM: - Both keyboards work - FnF7 lets me have both displays at onceMouse is another matter entirely. When the KVM connector is plugged into the docking station, the mouse pad dies. Unplug, and the mouse pad is restored. The BIOS settings are the same choices for both touchpoint and touchpad, Disabled and Automatic:    "Built-in [device] is operational.    If PS/2 mouse is attached built-in pointing devices are disabled."     Since both 'mouse' capabilites can be operational at the same time there are presumably two sets of circuitry, or a way for one set to be shared.

I'm using win 7 Pro, SP-1, Dell Vostro 64 bit laptop, a Toshiba Dynadoc and the dynadoc utility_II and a secondary monitor, and a MS wireless Mouse 5000.
The wireless mouse works fine when hooked up to the laptop at home with both laptop and monitor screen viewing well.
The problem is when traveling, unhooking the docking station and only using the wireless mouse with the laptop, the laptop does not recognize the mouse. The wireless sender attached to the laptop shows light indicator activity and the mouse lights up when manually activated, but doesn't recognize the wireless sender and shuts off.
I've tried unloading the dynadock utility program and changing control panel mouse settings. With system check the mouse seems to be recognized, but it doesn't reconnect to computer.

Ok, This is one problem I need some serious help for...
My PC's CPU usage is always high, and it gets very laggy if i have to do any applications what so ever. If i play a divx movie it lags, or even if I play music, the music skips. This happens even after a fresh format, windows xp updates installed, all drivers installed, virus scanned, and spyware scanned. I have no idea why it lags, it just does. I'm running a P4 2.4gh with 512 of ram. I know for a fact that it shouldn't be running this crappy. I was wondering if anyone could help.

After I returned from Holidays...I noticed that when I perform tasks that use considerable amount of CPU, the computer 'lags' and the sound seems to freeze. Each cycle being 1 sec long. It will continue to do so until I leave the computer and close CPU-consuming applications such as games, Media Players etc...It usually happens when I play games and watch movies though...

I initially thought that it was a virus so I scanned etc, then I thought it might be due to the CPU overheating, so I opened my machine and checked the CPU paste. It was fine no problems there. Then I checked the processes, nothing and finally arrived at System Resources where I saw that 'System Interrupts' was eating around 30 - 50% of my CPU. I have searched google and haven't come to a solution for this. I have updated my chipset drivers, graphic card drivers, sound drivers, Network card drivers, Motherboard etc. There is no effect whatsoever. It's really frustrating me as I can't even listen to music sometimes...I had used up all of my USB ports, so I tried taking some out, but there was no result...

When I restart it kind of calms down, but then it comes again. Even when I type in my password to enter Windows, the welcome sound freezes momentarily again. I have recently bought this system (custom built myself) so I'm really frustrated and cant think of a reason why this happens so suddenly

Any help will be greatly appreciated

A:Laggy performance during high usage - caused by System Interrupts

Welcome to SF, msjamalan!

If it's a virus or malware problem, please reboot into safe mode and run your scans. Malwarebytes should be your malware scanner.

If you have a lot of applications open at one time, you may want to bump up your memory.

You can also run msconfig and see if you can uncheck startup items. Be careful with this one.

Still, I wonder why this change has occurred after you have returned from vacation. Can you think of anything different before and after holidays?

I have seen this posted as an issue before but with no response from Lenovo. Anytime I dock my Thinkpad X1 Carbon 6th Gen to the Ultra Docking Station, my system usage skyrockets to between 10-30%, causing the fan to become fully enraged. (this also occurs when undocking as well) This has become more and more annoying with time.  The only solution I have found is to scan for hardware changes under the device manager, which immediately drops system usage to >1% (where it should be).  Lenovo.... please address this issue with a permanent fix.

I have a Latitude E7740 that runs Ubuntu Xenial (16.04). I dock it to a "Dell EURO2 Advanced E-port II" docking station. 
If I boot it in the docking station, everything works fine, and I find all my two DVI-connected monitors. 
However, if I undock, then put it into the dock again while running, it fails to enable the screens. I'm using a script called autorandr for switching between display modes - it uses xrandr. It tries to run:

Running this exact command after booting in the dock is doing the right thing, but after undocking then docking, it doesn't work.

Hello everyone,

I'm new to the forums and I'm here to possibly get some advice for an issue I'm having, learn something along the way, and help other people as well if I can.

I just built a brand new computer with an Intel Quad Core Extreme QX6850 processor. I have top of the line hardware and I'm running with Vista 64 bit. I also have 4 gigs of DDR2 Ram.

So here's the issue: My CPU usage is usually around 35-40% when idle and my mouse is constantly getting stuck and freezing for a few seconds. This usually happens when something is loading but I know this can't be normal because it's happening all the time.

I already tried reinstalling the mouse drivers and making sure they were the newest drivers. The mouse I'm using is a Microsoft Wireless Laser Mouse 6000 v. 2.0.

Here are the processes running on my PC:

Here are the services running:

And here is a display of my CPU usage:

I'm not sure what is causing this, so any help would be greatly appreciated. If you need any other information, please let me know.

Thank you!

My mouse (the pointer on the screen) has been flickering a lot lately. I think I've discovered that the flickering pointer corresponds with running AutoCAD 2005. With AutoCAD running, I opened Task Manager and my CPU usage hovers around 45%, even when AutoCAD is sitting idle (not processing a command). When I close AutoCAD, CPU usage drops to about 5-8% with a couple of other apps running (Outlook, IE). The AutoCAD correlation makes sense because I installed it a few months ago, which is when the flickering pointer started. I'm not sure if this question should be in the OS forum, or maybe hardware or applications, but I thought I'd start here.

My computer:
Windows 2000 Service Pack 4
Pentium 4 - 2.66 GHz
524 MB RAM

Any ideas on how to reduce CPU usage with this program? My co-workers are using computers with the same operating specs, yet do not have this problem with AutoCAD 2005.

I've been trying to fix some issues with my computer in regards to its speed and have gone through and deleted old data, defragged, got rid of processes and the like however things still run slow. After I open up my system processes without anything running it generally uses 1-3% of my cpu power, but when I move my mouse around in little circles outside of the window it goes up to 46% and even higher when its in the window. Also when playing games I noticed that the games run fine if I move around with my keyboard but instantly lag if I move my mouse around.

i went into dxdiag and tried the music section and it told me i had issues with direct sound. by this time i had checked my speakers out and they were working but the noise coming out of them suggested that the cones had blown.

next boot up, the computer took an enormous time to load, approx 10 mins. from here the mouse lags for the majority of the time and cpu processes suggest a constant 30% going all the way to 100% for small tasks.

looking in processes, the peak memory usage for system is 800,992k and various others are higher than normal.

i've run norton, spy-bot, ad-aware, ewido, zone-alarm suite, spy doctor, avg, spy hunter, bazooka...

i have started in safe mode but it still takes 10 mins to boot up to the log on screen, system restore doesn't work and i'm clueless!!!

will be reformatting once i have ascertained i have the required drivers; tried adding sp1 to the comp and it tells me that atapi.sys is running and i should quit; even in safe mode.

i need this comp for CAD work so its kinda urgent, any ideas please!!!

cheers, hrtbob

A:Solved: mouse lag, slow boot, cpu usage high...

looks like it is a motherboard failure, which will take 4-5 weeks to replace under warranty- thats nearly the same time as it takes to get a reply from anyone here...

I've recently come under attack from something glitching in IE, that will under certain conditions (certain webpages using a certain code I'm presuming) cause Iexplore.exe to use excessive amounts of CPU when moving the mouse around the IE window. When the mouse goes idle, it will drop instantly to it's normal CPU usage of something between 0-3%, which is how it used to be(and rightly should be). I've run IE in the no add-ons mode and still encountered the problem. I've completely un-installed and re-installed IE and the problem persisted. This is the first I've encountered something of this variety and my searches for precedents have come up with nill, so I thought I might draw on some experience other than my own in my endeavor to understand this aberrant behavior. It does this only in IE window panes, and only when certain sites are open such as iGoogle homepage and YouTube. Has this been seen before by anyone here?

I don't know if I posted this in the right forum, but I have Windows XP so I figured I'd start here.

I'm having a problem whenever I move my mouse. The computer screen completely freezes up and doesn't update itself until I stop moving the mouse. Whenever I play computer games it is the most apparent. If I move my mouse at any point the game becomes completely frozen until the second I stop moving it, then everything is totally fine.

I've run my computer in safe mode and everything runs fine, no freezing or anything, so I don't think it's a problem with the mouse. I updated my video drivers (I have a GeForce 8600 GT) and it didn't seem to help it. I've tried closing certain processes in the task manager, but no improvement.

When I have the performance tab on the task manager open I can see the CPU usage go up to about 50% whenever the mouse is being moved. When I boot in safe mode, there is almost no CPU usage when the mouse is moved.

Any advice or ideas would be appreciated.

Hello everyone, I've been having a very weird problem recently, in which I BELIEVE is involving high physical memory usage. Sometimes I will be doing things such as playing a game, or watching a stream, and my computer will run fine for a little while. But at random times, my computer will majorly slow down and sometimes even crash. If it doesn't crash, sometimes it will get so slow to the point where I have to hold down the power button and manually shut it down. Every time my computer slows down I notice it is using a TON of physical memory. It's actually happening right now. My computer is going very slow and it's using 6.22 GB memory out of 8. There are no big programs running right now, so I don't understand why it's being slow. I hope someone is able to help. Thank you for taking the time to read this!

Update: I just tried to open chrome, and the computer froze completely. It would not unfreeze. After leaving it frozen for a minute or two, the screen went black. This is becoming very frustrating.

A:Very high physical memory usage, no high usage programs running
