cool, thats exactly my setup! but mine is laggy... which chipset and driver / notebook, and which OS do you use?

So - I swapped out my VGA cable for a DVI. Even though previously the higher res monitor on the DVI cable was slower (and I swapped the other cable), that seems to have helped fix it.

e.g., before I had:
- Monitor 1: DVI -> VGA adapter, VGA cable - running fine
- Monitor 2: DVI cable - running slow

Replaced monitor 1's cable for a straight DVI, and monitor 2 seems to be running normally now.

Not sure if that's helpful or not.

It is a Samsung series 9 laptop.

PS: In the "Samsung Settings" application, there is a tab called "General - Silent Mode". If I select anything else than "off", the display becomes terribly choppy! This might be a tips for anyone with choppy displays. Check your power saving options!

My thoughts exactly. Same exact hardware, same exact setup, same exact problems. Anxiously awaiting resolution. Happy to assist in any way needed.

yeah, i noticed the thing with the silent mode too. maybe there are more power saving options... i'll check that. i've a samsung series 7 notebook.

have there been any updates on this? i got my lenovo carbon x1 with targus dual vido usb 3.0 dock last week and have had nothing but a headache since.

updated both lenovo bios and displaylink drivers to 7.2 and i'm getting the same issues as previous posters where it feels like i'm working on my 2 external monitors through a remote desktop. if i don't do anything besides move the cursor about the screen it's nice and smooth but as soon as hover over buttons/icons, move windows, do any kind of computing it lags up a lot.

for now i've just got one of the externals hooked up via minidp port and it works as it should, but the single monitor still attached to the dock is still laggy.

Hi

The lagging also seems to be gone for me with the new driver..
I have a Lenovo X1 carbon and Lenovo dock..

A thing I have noticed that may be a help to others, is that the minimum processor speed in advanced Power options need to be at least 30% when the computer is plugged in, for the dock to work properly.

You fin the option by going to:
Control Panel->Power options->Choose when to turn off the display->Change advanced power settings->Processor power management->Minimum processor state->Plugget in

My theory is that the minimum speed must be set because the most low power processors have a variable processor speed, to ensure that there is always enough processor time for the Displaylink to be serviced the minimum speed must be set.

Regards.

This is the same kind of solution that I found using my Samsung Series 9 notebook. Everybody with this kind of problem should investigate the Power Options!

The new drivers + increasing the minimum processor speed in power options have seemed to have mostly solved my issues. I still see occasional mouse lag. Perhaps the displaylink driver should set these power options by default? Or prevent the processor from going into that deep of sleep to begin with?

I have, however, noticed an issue with Windows 8, when a metro app is mounted to the side of the screen, I see the monitors flashing black occasionally. Seems to be a driver issue as this doesn't occur when using built in monitor, and haven't noticed it when plugged into the monitors through displayport.

Scratch that. Lag is still prominent, especially when switching between windows ie (alt-tab). Additionally when copying larger files over ethernet the device will appear to reset (screens go black for a second, ethernet connection is lost).

Having the same issue with my Lenovo Yoga 13.

Screen keeps disconnecting, and usb ports freeze as well as the screen freezing and going blurry.

Having the same issue on a surface pro
 

I'm using 7.2 with two external monitors over DVI on a surface pro with USB3.0 Lenovo dock. I tried hacking up the USB drivers I found in the previously mentioned tutorial thinking it would fix performance, but it hasn't helped.

I can pretty consistently repro the issue by opening Excel, highlighting a cell, hitting ctrl+c (copy) and then when the little animating rectangle around the copied cell starts moving, the screen goes fuzzy/pixelated.

I wish I could say I don't need to use Excel enough for it to matter, but such is the story of my life!

If you make the Excel window not quite maximised on the screen, do you get the same problem?

Wim

Been following this post for sometime and I'm in the same camp as most.

Win8 Pro on a Lenovo X1 Carbon using the USB3 dock.

The drivers from April 3 made the lag & display situation better than before but not 100% resolved.

The display issue did go away completely as best as I can tell. That was the bit where pictures would be "fuzzy" for a bit especially during transitions. I could always see that during logons but not anymore. So that's good.

However, the mouse lag is still there. It has been improved but you still feel like you're using a remote desktop for sure. I'm using a wired mouse/keyboard to eliminate any wireless issues.

If I can contribute any meaningful info please let me know. Thanks!

Yes, the size of the excel window seems to have no effect - same behavior.

Also happens when an IM comes in and the Lync app in the taskbar gets "needy" (blinks/animates) the entire screen goes fuzzy until I activate the needy app.

I have the same problems with a HP Envy x2 notebook: slow performance and disappearing mouse-cursor. I've installed the latest version of the DisplayLink software.

The notebook is running on Windows 8. I'm using a 19" HP LCD monitor with a resolution of 1280x1024. Not very high...

I hope there will be a fix for this problem. My customer is a little bit disappointed.

Could you see if increasing the priority of DisplayLink Manger in task manager helps improve this?

http://displaylink.org/forum/attachm...6&d=1366991099

Wim

I've changed the priority to High and I'm not seeing any difference in performance I'm afraid. Still have lag.

I am also having the same problem with screen lag, mouse lag and fuzzy.

Lenovo Thinkpad X230T (latest drivers and BIOS)
Windows 8 Pro
Intel HD 4000

Toshiba Dynadock USB 3.0 w/ DisplayLink_7.2M0 drivers and updated firmware connected via DVI-D cable to a BenQ XL2420T monitor using 1920x1080 resolution @ 60hz.

I wish it supported 120hz :(

Mouse lag
 

I have the same problem with mouse lags, like others
using Dell Dell Inspiron 14z, Windows 8 , Intel HD 4000, Toshiba Dynadock USB 3.0 and latest drivers 7.2M0, two LG IPS235P displays 1920x1080
I am forced to connect first directly to laptop and second to hub (no difference HDMI or DVI same behavior)
Another issue is Skyrim and other games - DisplayLink drivers are unusable

Same issue here with a Thinkpad Helix and USB 3.0 docking running with 2x 24" monitors at 1920x1200 via DVI. OS is Win8 64-bit.

The lag occurs especially when switching from an application displayed on one monitor to another application displayed on the other monitor.

There's also a bit of lag when switching between cells in Excel or switching between applications. For instance: if alt-tabbing from Excel to Outlook, the mouse will "hang" for a sec after alt-tabbing. This is very consistent.

Okay - I managed to fix it.

I updated everything that was available for update in Lenovo System Update.
Including the optional stuff.

My best guess is that it was the BIOS update that fixed it...

just installed the bios update to my samsung series 7. its a lot better, you're right! thanks for sharing! :)

Running latest Carbon X1 bios update along with other updates from Lenovo System Updater and the issue still exists.

Same problem... Dell XPS12+ Win 8 + DisplayLink dock
 

mouse is laggy and I have tried all workarounds that I can find... driving me crazy! Hope someone can find a fix.

Can you ellucidate the form of lagging you are experiencing? Is it an occasional delay in update, or a continual latency in response?

Having same issue with my Helix and Targus Universal USB 3.0 DV Docking Station. I can see the mouse skip around. BIOS update didn't solve mine.

Just to try and expand on Dan's post, is it just the mouse that is lagging or is the whole screen freezing for a second? You can check this by just playing a video on the screen at the same time. If the video pauses at the same time the mouse pauses then the screen is freezing for a second or so.

If this is the case then I think we understand what the issue is and working on a fix. We have found a problem and the problem is usually rare, but we suspect it could be timing related so some systems show it a lot more than others. If it was happening often then it would be annoying and would explain the number of users in this thread experiencing it.

If you could confirm if it is just the mouse that lags or if it is the whole screen it would help confirm.

Wim

Hi Wim,

I wanted to reply in this thread, as I'm experiencing the periodic momentary freeze, and wanted to give whatever configuration info would be helpful...

First off, I upgraded to 7.2 M1 yesterday (5/11), and it's been light years better than the prior version in nearly every way. The prior 7.2 was maddening under Windows 8 (slow ethernet, incessant unplugging/replugging to get things working after sleep, etc.)

My configuration is:

Plugable UD-3000
Lenovo Twist with Windows 8
DisplayLink monitor set as my main monitor

I get the momentary freeze (1/2 second in length) every few minutes. Both the mouse, as well as any streaming video (SlingPlayer in my case) freeze on the DL display.

I managed to fling the mouse pointer over to the built in notebook's display during the freeze, and it was responsive there -- there were two mouse pointers displayed for that time -- one "frozen" on the DL display, and the responsive one on the notebook's display. The frozen one disappeared once the display "thawed" :)

Once the freeze is fixed, my Windows 8 setup will be nearly perfect. It'll be time to critique my Macbook Air's drivers at that point...

+1 for this issue with a Lenovo X1 Carbon. I've verified via video that it is the whole screen that is freezing.

Was the Displaylink dock + Windows 8 = fuzzy lag on extended screen -ever fixed?
 

Hi Wim,

I'm facing the same problem where two of my monitors are connected to the dock using DVI-I and DVI-D respectively and the one with DVI-I is showing the lag with my laptop (Lenovo YOGA-13) running Windows 8 enterprise version.

It's the worst user experience. Please help.

-Rmvm

Sorry for the delay. Yes! I just checked this with the video method you mentioned Wim. Video + mouse froze at same time.

ALSO though, the mouse speed lags without video problems. For example, I move the mouse around and it doesn't always move at the same pointer speed. Sometimes it moves very, very slow and has this "lead" feeling to pointing around. I have the mouse settings on my computer for "Motion Settings" all the way to fast. Sometimes I have to pick up my mouse to get it to move to the other side of the screen... (meaning I have to pick it up, move it to the right side of my mouse pad, then move it again to the left to get it to track across the screen all the way to the left).

I'm on a similar set-up getting mouse lag and blurry icon/text when connected to my port replicator.

Set-up:
Lenovo X1 Carbon Touch running BIOS 2.53
Lenovo USB Port 3.0
2 Samsung 2043BWX Monitors connected via DVI
Running DisplayLink Driver 7.2.46733.0 - This is what is showing after installing the most recent 7.2 M1 drivers

Experience:
The mouse feels like it is running on a low FPS setting. Similar to the mouse movement you get your system drags running a video game at low FPS. There are input delays and mouse freezes. Working with this lag is near impossible for long periods due to always having to do tiny movements in the mouse to correct for the lag.

Fuzzy images text occur when there are changes on the screen. The best example is changing folders in Outlook. Clicking on a new folder results in all the text in the program flickering through two or three different levels of blur. This also happens to taskbar icons.

I'm not seeing the video hang ups other are reporting, the system as a whole just seems to be running very slow.

little update....

I found another mouse in the closet - was using a Microsoft wireless keyboard 3000 v2 and Microsoft wireless mouse 5000 that use a single dongle.

I got out another mouse - Microsoft wireless mouse 5000 that has a separate dongle to itself. Working fine so far! Will update if it degrades.

Updated to the latest 7.2 M1 drivers and still experiencing the same behavior.

Possible fix?
 

Hi All

I've attached a development build of 7.2 M1 but includes a fix for the momentary screen freezing that I suspect is responsible for some of the "mouse freezing" or "mouse lag" posts on here.

As a reminder, if you are using a wireless mouse, make sure you are not getting USB 3.0 interference as covered in this article.

Please let me know if this improves the mouse behaviour.

Wim

Running now for about 45 minutes, and the stutter appears to be gone! I'll report back if I see any glitches.

Regarding wireless mouse interference, I experience issues when my Logitech Unifying USB receiver is plugged directly into one of the USB 2.0 ports (on the back of the Plugable UD-3000). No idea why, as I thought that the interference was limited to the 3.0 ports. I have the receiver on a 3 foot USB extension cable, physically placed about a foot from the Plugable, and it works fine... Go figure.

I've been troubleshooting the lag and blinking issues for a week now, just finding this thread today. Good timing - I tried Wim's pre-release drivers and things are better. The blinking when docking Xbox Music on the side in Windows 8 no longer happens, and the general mouse lag does feel better. I wouldn't say it's as smooth as working directly on the laptop (Dell XPS 12), but it's within the realm of acceptable now.

I look forward to further improvements!

Update a few hours later: looks like I spoke too soon. Although the lag is maybe a little better, it's still noticeable. The blinking to black is there, too, but it's different now. It seems to blink more quickly and less often than before. Also, I'm running two DVI monitors and one of them only has the Zune client in "tiny" mode to play some music. When I hit the Windows key to bring up the new start menu, there's a definite pause for a second.

Wish I could report an improvement but I'm still in the same boat. If anything I would say it maybe even got a little worse with that update.

I really appreciate the effort though! Nice to see a company posting potential fixes like this within a thread rather than making their users wait.
