Lenovo T400 / T500 :: Dual External Monitors Without A Dock On T440p?
Mar 15, 2009
Is it possible to use two external monitors with my T440p (20AW-A08500) with Intel HD Graphics withou having to buy a dock? I normally use my laptop at home with the lid shut and two monitors attached.
I used to have X1 (still do - now up for sale) and that was happily connected to two monitors via HDMI and via a MiniDP to DVI adaptor.I wrongly assume when I bought the T440p that I would be able to somehow power my existing two monitors from the single MiniDP port.I have seen their is a Lenovo DisplayPort to DualDisplayPort adaptor - but this talks about ThinkCentre usage - no mention of Thinkpads. Plus the price of this adaptor is pretty steep.
I have a T420 that I'm using with a Mini Dock Series 3 - 90W 433710U docking station. I'm trying to connect to two external monitors (both HP 1965's) using the DVI and VGA outputs on the docking station. From the VGA output, I'm running a VGA (M) to DVI (M) into my monitor. I can only get either the DVI or VGA outputted monitors to work by themselves, but not together. When I connect both external displays, it will switch off one of the external monitors (the first one connected). Both are verified working as external monitors with the T420, just not at the same time. When using the DVI output, I can get dual monitors to work using the ThinkPad display as one monitor and the DVI-connected external monitor as the second. Is there a way to connect to two external monitors from a T420 with a Mini Dock Series 3 - 90W 433710U docking station? Or do you a multi-monitor adapater, such as an Cirago HDX3DV01 to do that?
We have 2 new T440p (i7 4800MQ, 16gb, ssd) which we installed with clean Win 8.1 and the newest drivers (intel hd 10.18.10.3345, nvidia 220.127.116.1182).
The laptops run on 4 ultra docks with different monitor configurations, mostly dual display, one single display, mostly samsung displays, always one display via dvi, second displays vga as we did not receive our display-port adapters yet).
In all configurations we have the same problem: Between every few seconds and about 20 minutes the external screens flicker and get rediscovered. Often this happens in Chrome or when doing some graphic-intensive stuff, but we cannot trace it down. Takes a few seconds to rediscover and all windows not in fullscreen are resized afterwards, because of display resolution detection and mostly we get the Display port new topology notification... We already tried with disabling the nvidia via the nvidia gpu settings and only using hd graphics but that didn't work.
A few years ago I had problems with my T400 discrete grafics, but then I could disable it in the BIOS which does not seem to be possible with the T440p...
I just got myself a thinpad T440p and was planning on getting a docking station. Since i have never gotten one before i was confused on which one should i get. I wanted to get the thinkpad Ultra Dock but was confused on how i would determine if i should be getting the 90W, 135W or the 170W. I live in Canada, Ontario if it makes a difference.
I was also curious, whats the main difference between the basic dock and ultra dock. Is it worth it for me to get the ultra for work?
I know the Intel 4000 video can only handle dual video, but is there any way have both those streams on external monitors. I have one that is extended and I would like to use another port to simply passthrough the interal display signal. I am using the series 3 miniport plus which has two digital/dvi ports and a vga out. In connecting to the second digital or the vga I get no signal. Likewise with the side VGA on the PC. I wouldn't even mind if the laptop display stayed lit as long as I could see it duplicated on a real monitor AND KEEP MY EXTENDED DESKTOP on another extenal monitor.
Seems like an obvious feature for a docking station.
I have a T510 running Win7 64-bit. For at least 3 years, I have had the same dual monitor setup (2 DoubleSight DS-1900S) running off my minidock with the laptop closed. The rgith monitor is the primary, running off the DVI port, while the left uses the analog port. I was away for a week at Scout camp, powered on the system once while I was there, and when I came back to the office, my monitor setup started failing.
Specifically, the right screen is active but it no longer displays the signal being sent to it. When I powercycle the screen, I can see the display for about a quarter of a second, then it goes blank. When the problem first started, I could cycle it about 20 times and eventually it would stay on, until I left the unit overnight and it went to sleep, at which point the probelm started again.
Sounds like a wonky monitor? I have a backup set of monitors that I swapped in, and had the same exact problem, so that appears to rule out a mechanical defect. More fun facts: I can only use the laptop screen as a standalone display. I cannot get the multidisplay control panel to open, even though my left screen is powered up. However, one of my programs that normally launches to my right (main) screen will still launch, but not to my laptop screen. It really wants to live on my right screen, even when that screen is not powered on (I can close the program by accessing the icon bar at the bottom of my laptop screen).
I just received my new t430 and having issue with dual monitors. I am using the Intel HD 4000. I have it connected to a ThinkPad Port Replicator Series 3 (Type 4336). The docking station only support VGA connection. My new t430 only has a VGA connection on the side.
I have 2 monitors. One is connected to the VGA on the docking station. The other is connected to the VGA on the t430 itself.
While the machine is docked, Monitor #1 that is plugged into the docking station works, while Monitor #2 that is plugged into the t430 does not.
While undocked. Monitor #1 does work (obviously because undocked), but then Monitor #2 does work.
So I know both monitors are working and configured for VGA input. My questions is, why can't both work at the same time? While undocked, I can use laptop screen and Monitor #2 as a dual monitor. So I don't believe there is something wrong with the Operating System (Windows 7).
I used to be able to do this on my t420. With one monitor using VGA, and my other monitor using a DisplayPort. But looks like this model my company purchased doesn't support a DisplayPort (at least don't have the connection.)
New ThinkPad T440p and the first issue I encountered is there is no option to disable the touchpad when an external mouse is detected. I don't want to do it via the bios or some other hack as I use the touchpad when it is not convenient to use an external mouse. So it should be able to do the switching as needed, this is a simple feature that other manufacturers have had for years and years.
I already upgrade the UltraNav Driver to the latest v18.104.22.168 and that didn’t present a solution. I am running Windows 7 SP1 - 64bit.
This is a brand new TP T440p and I installed a fresh copy of Windows 8.1 Pro on it (licenced). I've applied all Windows updates and installed all drivers/BIOS updates from Lenovo System Update.
The computer works fine, but when I put it to sleep and wake it back up, the external monitor is almost always flickering (there is a 1mm movement to left and right, line by line - I'll shoot a video, if the camera will be able to capture the movement, because it's very "fine"). Sometimes it stops after a few minutes, but most of the time I need to re-boot the computer.
Also, not always, but many times the WiFi connection is lost and I can't reconnect unless I reboot the computer.
I have a T420 Thinkpad and have 2 external monitors connected; one using VGA into the docking station and one using DVI into the docking station. The laptop does not recognize the mobile PC display as an option when I attempt to extend to a 3rd monitor. The ultimate goal is 3 monitors extended: 2 external and 1 (the laptop display). Is this possible?
I am running a IBM Thinkpad W540 with a Lenovo Ultra Dock Docking Station 170 (Model 40A20170US). I have 3 Asus 23.6" LED HD Monitors (Model VN247HP). These monitors have a standard VGA connection and 2 HDMI ports, By default you are provided a VGA cable and a HDMI-DVI cable. When I plug these monitors into the Ultra Dock no signal is found(including the VGA).
When I plug into the direct VGA port on the laptop, the monitor gets signal. If I use a Mini-DP connection with a Mini-DP-DVI adapter I get signal just fine. If I plug my this monitor into my desktop under HDMI and DVI connections it works just fine.
I have gone into the bios and confirmed that under display the "Video Mode on Dock" is set to Advanced(I tried standard and it did not work any better). I have the latest video drivers for the Intel HD graphics driver (10.18.10.3412) and the NVIDIA Quadro K1100M (22.214.171.12452). The USB ports work just fine, as does the power cable for the docking station. I tried applying the latest firmware update but the program runs and nothing happens. I checked for any other drivers that might have resolve the issue but have not had any luck.
I am running Win 7 on a new T440p. I can't connect to a projector using F7 nor are the brightness controls working (F5 and F6). The other HotKeys are working. I have updated to the latest HotKey driver.
I've purchased this ram from the lenovo site for my T440p laptop and they said its compatible with the original 4gb RAM which it has. but when I install it in the other free slot and turn it on it cames with a black screen and stucks in it!! When I take it out everything is ok and it turns on normally.
I just received three new T440p laptops using Win7 Pro. Unfortunately, the wireless link to keeps disconnecting ever so frequently on all the machines. I have updated the Wireless drivers, reinstalled the BIOS and even optimised power options to enhance the wireless perfomance but none have worked.
Just got a T440p and it's working fine. BUT when I go into an application like Word and either hit the function key or combine it with the Alt, Ctrl, or Shift key, I still get the default action of the Funciton key. For example, in Word, the Alt-F9 combination is used to display field codes. When I do that, however, I get the Control Panel popup. Similarly, in a browser, I should be able to hit the F12 key and get the Developers pane at the bottom of the screen. But instead in IE, Chrome, and Firefox, I get a My Computer popup.
I recently purchased my new notebook (Lenovo T440p) which comes with OPTIMUS integrated Intel graphic card coupled by GeForce GT 730M 1GB. I tried to play some games; however for some reason in game options show, that my Intel HD card is being used as a default graphic card. This suggests that OPTIMUS technology is not switching the graphic card properly. System running on windows 8.1 Pro 64bit. How to enable Optimus switching?
IBM/Lenovo laptops and desktops for a long time. I recently purchased a T440P laptop with a standard 7200 RPM HDD in it. In the past, with previus models, when I wanted to troubleshoot the current Windows install (virus infections etc) I would use UBCD4WIN on a USB stick to boot the computer to USB and access the hard drive to pull data off or remove files infections etc. With this new T440P I cannot seem to see the hard drive when I boot it up with the USB stick.
I can boot the computer just fine and run the USB based OS without trouble but I simply cannot see the hard drive.
So far I have tried: -Adjusting UEFI to Legacy and/or "Both" -Adjusted CSM to Yes and No -Disabled/Enabled Secure Boot
and several combinations of all of the above in hopes it was the issue but it doesn't seem to change my ability to see the hard drive. It simply doesn't show up.
The drive itself (in the T440P) is a standard HDD (not SSD) and is formatted NTFS with Windows 7 64bit installed on it.. The UBCD4WIN is a basic "Windows XP" x86 (32 bit) OS on a USB stick and the USB stick is formatted FAT32.
In previous lenovo models (T400/T410 etc) all I had to do was switch AHCI to Compatibility and I could see the drive but this one is giving me a real fit and I am not exactly sure if its a controller driver, UEFI or something else.
how to see the hard drive when booting to the USB UBCD4WIN stick?
I tried to do fn + f7 to toggle display modes as I want only laptop or monitor display, not both. But when I do fn + f7, the small window pop up ask me if I want to turn on caret browsing or not. How to toggle display modes between laptop or monitor for t440p, window 8.1?
First is while I'm docked in at work I use a normal key board and it has a right click botton on it. When I go home I do not have that button and know for previous models there is a short cut that you can do to "right click" rather than going to the track pad and right clicking.
Second is for the F1, F2, F3, etc... to work I have to hold down the Fn button. Is there a way to turn around the keys to where when I hold down the Fn key and press F1 it actually mutes the sound. I guess im trying to say is there a way to switch the primary function of the F row?
After updating to the latest video drivers from the ThinkVantage Update Retriever, our Lync clients crash when sharing desktop on our T440P series and X240 series. I noticed when I uninstall the video driver I am able to screen share without incident. Also, if I update the driver from Windows Update I am able to share successfully. We use the update retriever and thininstaller to install our drivers in our environment. I have tried uninstalling the Lync updates all the way down to the base version and experience the same issue at every level. It crashes 100% of the time when sharing desktop. I have tested it on T440p machines in our environment that do not have the latest display driver, and no crashes occurred. Here are the specifics:
Thinkpad X240 [20AL] Thinkpad T440p [20AN] ThinkVantage Update Retriever 5.00.0007 Thinkvantage Thin Installer 1.2.0010 Intel HD Graphics Driver - gid634ww (10.18.10.3412) Microsoft Lync 2013 SP1 32 Bit (15.0.4569.1503)
my new T440p with built-in WWAN Ericsson N5321gw doesn't recognize the SIM-Card. I'm running Win7 64 Bit and in the device manager, I can see the Ericsson device showing up without any errors. Once I launche Access Connections, I receive the error message there's no SIM card inserted and I should insert the SIM and try again. The SIM is inserted as shown next to the slot (although I tried other ways, too). I tried two different SIM-cards just to be safe, both SIM-cards are working in my phone.
I have a T440P, Up to recently, I was in Windows 7 with Lenovo Power Manager set with threshold charging limited at 63%, So far so good. Now, Windows 8.1 has been installed from scratch (Not an upgrade).
The laptop with windows 8.1 still stop charging at 63%. But there is no Lenovo Power Manager available for windows 8.1. I don't find any solution to deactivate this limitation...
Imaged with preconfigured company Windows 7 x64 image I have used hundreds of times before via MDT. WDS packaged T440p drivers (downloaded from Lenovo website) are injected as part of the MDT installation process.
All windows updates applied (except for the Lenovo PM Device Driver otherwise the thing no longer reboots or shuts down properly anymore) BIOS flashed to latest T440p revision.
Run Lenovo System Update to install hotkey drivers and receive the following:
As you can see Win7 x64... driver says no.
Restarted and tried again... error.
Tried downloading the driver manually from [URL] .... Same error.
Searched for and downloaded version 5.40 .... Same error.
I ran Lenovo System Update 2 days ago on another T440p laptop, may have been a slightly different internal spec... not sure but I'm fairly sure the driver was named differently in System Update. The driver Installed on that machine fine and functions as intended.
The driver could very well could have been updated since then I guess. I do also know this is a newer batch of T440p's as the box configuration that it ships in has changed and looks completely different.
My T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.
