Connecting Thinkpad T440s to a 21:9 (29" ultrawide) monitor

I have recently purchased a 29" ultrawide LG monitor, with a 21:9 aspect ratio. When I plug it in, it recommends a 2560x1080 screen resolution. I was disappointed as the display settings on my thinkpad only go up to a 1960x1080 resolution.  Is there any way to achieve the correct resolution? I am currently connecting to the monitor using the dual DVI-D cable that came with the monitor.  
I am wondering if there is a driver update that will support this, or a change in connection method? 
Thank you
To update:  I am now connected via an HDMI/Display port cable instead of the DVI cable. This has not given me the option to increase my screen resolution in my display settings.  
Solved!

FYI - After much research and consultation I have fixed it. Turns out I needed to update my Intel HD Graphics Driver to the latest version which supports a 2560x1080 resolution. I also purchased the HDMI/Display port cable which didn't solve the problem but probably helps with quality.

  • Thinkpad T440s cannot connect to displayport

    Hi, I just installed arch on a Thinkpad T440s and I've managed to configure most things to my liking, but for some reason I cannot recognize displays plugged into the mini displayport. No matter what I have plugged in, the output of
    $ xrandr -q
    is always:
    Screen 0: minimum 8 x 8, current 1600 x 900, maximum 32767 x 32767

    This also doesn't show the VGA port at all, which confuses me. I have the latest version of the xf86-video-intel driver installed. I also tried forcing output to DP1 with:
    $ xrandr --addmode DP1 1600x900
    $ xrandr --output DP1 --mode 1600x900
    but this failed with output
    xrandr: Configure crtc 1 failed
    Any help would be greatly appreciated!

  • Thinkpad T440s freezes with 2nd monitor via dock

    Hi there - I have a strange problem with my Thinkpad T440s:
    Connecting a 2nd monitor directly (VGA) works like a charm, however putting the Thinkpad into the docking station (with the 2nd monitor connected to the dock) freezes the system. Without the 2nd monitor the dock is working fine. When booting with the 2nd monitor connected to the dock, both screens stay black as soon as the kernel loads.
    Is this a known problem / any ideas? Can I somehow help fixing this problem?
    I know that I'm not the only one since I have found other people reporting this here: http://thinkpad-forum.de/threads/165520 … -und-Linux
    They also provided an xorg.log (http://pastebin.com/Qk7nHVwt) which shows nothing suspicious, I guess...

    Same issue with my T440p. Happens with VGA, DP & HDMI (haven't tested DVI) on the dock. Undocking unfreezes it. If X is running the X server freezes and consumes 20% CPU, if none is running a kworker process does that. Even with no monitor attached it will freeze when the builtin monitor wakes up from sleep (again, undocking helps).
    Here's a stack trace from the frozen X (^C'd while it was frozen from waking up the display, gdb only reacted again after undocking):

    Edit: "Solved" by returning the laptop. This issue plus the loud (and not well-controllable) fan and the lack of support for the fingerprint sensor (different from previous ThinkPad models, it's from Validity Sensors) just aren't worth the trouble.

  • Thinkpad T440s Ethernet Adapter Automatically Disabled

    I have a Thinkpad T440s 20AQ with a Intel I218-LM ethernet adapter. The OS is Windows 8.1 x64
    Since approx. half year ago, the ethernet adapter started to disable itself automatically every 1-4 weeks. The occurance of this problem has no pattern and is unexpectable.
    When it happens, I cannot reenable it under Network Connection window. Rebooting the system has ~50% chance to solve this problem. The reliable way to solve this problem is disable and reenable the adapter under Device Manager.

  • Thinkpad T440 : Speakers not working only headphones

    I upgraded the drivers, tried to reinstall the OS but unfortunately nothing helps.
    Thus, i disassembled the laptop and tried to figure out where the problem is? i find out that the speakers are working! I tried other speakers and the same thing happening > no sound
    I tried to plug/unplug the headphones jack connector many times but without success

    But I fixed my problem, I was increasing/decreasing the volume from the tool bar it wasn't working! I but I could see the waves when I put some music playing and no sound nothing was coming.
    So I tried to deactivate the volume from F1. After that I increased the volume from the toolbar and hopefully it was working! so i figure out that the F1 and the sound card wasn't really syncing.

  • ThinkPad T440s will not turn on

    Hi I'm to the forum and I have a problem with my Lenovo Thinkpad t440s. When I had switched HDD with another Lenovo and tried turning it on it just couldn't come on. So I tried removing its external battery and the ac adapter which didn't work. I also tried switching the old HDD back, and also tried removing its internal battery out for 60 seconds. Everything I've tried has failed, and would like to know if I should just send it to some Techs to look over it.
    Also before I tried swapping the HDD I had previously turned off the internal battery because I heard people should.

  • ThinkPad T440 - Bluetooth headphones do not work

    I have a ThinkPad T440.
    It has Windows 7.
    Issue: The ThinkPad T440 recognizes the headphones when i turn the headphones on. But the ThinkPad T440 does NOT pair with the headphones.
    I have downloaded the latest drivers but the issue still persists.
    The issue i'm having is NOT specific to the type of bluetooth headphones i'm using because the issue happens with any type of bluetooth headphone i'm using.
    The headphones do work because i can pair the headphones to my iphone 5 and i can listen to music/videos on my iphone with the headphones.
    Previously i had a ThinkPad T430 and the headphones worked fine.
    Also, i do have a mouse that is bluetooth and the mouse works fine with the ThinPad T440.
    My bluetooth radio is turned on.
    In Device Manager, under Bluetooth Radios, it displays Generic Bluetooth Adapter and Microsoft Bluetooth Enumerator. Both of these have the latest drivers installed.
    Does anybody have a solution to this issue?

    Another forum enlightened me to the fact that T440s using Intel Bluetooth chips. This was the key to finding the secret sauce to get my Plantronics Voyager headset to work with a Lenovo T440.
    The magic occurs when you head over to Intel's site and install the latest "Intel® PROSet/Wireless Software for Bluetooth® technology" for your platform:
    https://downloadcenter.intel.com/SearchResult.aspx?lang=eng&keyword=bluetooth
    In my case, it was:
    https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24679&lang=eng
    I'd then reboot as a safety measure. After installing it, there are no additional Start Menu items, but once you Add a Device from the Bluetooth Devices screen, all the appropriate device drivers for telephony and headset are automatically found.

    T440 definitely does not support XP.  As Microsoft will stop supporting XP within a couple months it did not make business sense to provide/test drivers for XP anymore.  It is past time to start using a different OS.

  • Thinkpad T440 BIOS update without Windows Utility - problem

    So I wanted to update my BIOS from 2.23 to 2.30 from here - http://support.lenovo.com/us/en/downloads/ds035967. First think's first - my T440 does not have any CD/DVD, so obviously I need a bootable USB to update my BIOS. Second, I'm using Ubuntu and no longer have (or want to have) the Windows installation.
    In order to make a bootable USB with the BIOS iso file I tried 2 things:
    1) Tried following this guide - httpawww.lenzg.net/archives/358-Updating-the-BIOS-on-my-ThinkPad-T440-without-Windows-or-a-DVD-Drive.html, everything seems to be have worked, except the fact that it does not boot when I try to boot trough the USB, and I bumped there.
    2) Open a Windows on my second laptop and try to make a bootable USB from Windows (maybe it will help?). Tried both the standard Windows USB DVD Tool and got the error - "The selected file is not a valid ISO file. Please select a valid ISO file and try again." Fair enough, here I started to get suspisous that something is wrong. I tried and burned a bootable USB with PowerISO, but again as method 1) it does not boot.
    Just to mention that in my BIOS I have the Secure Boot off and both the Legacy mode and UEFI, with Legacy first.
    Any ideas how to proceed?

    Sorry, I don't know about Linux much less then nothing.
    But I'm sure there are the following tools for:
    - disk/partition management, to make primary partition on the stick as active, to be bootable
    - mount .iso image as a virtual CD to explore that one and get its content. Or, perhaps, there is .iso content viewer that supports CDFS.

  • Thinkpad T440s BIOS update via PXE fails with "invalid system disk"

    Hi,
    I'm trying to boot via PXE to the BIOS 2.24 update ISO image because the T440s comes without a DVD drive. The Thinkpads are running RHEL 6.5 workstation installed. I'm using syslinux 6.02 and the following menu entry:
    label lenovo_t440s
        menu label Lenovo Thinkpad T440s BIOS 2.24 Update
        kernel memdisk
        append initrd=lenovo/t440s/gjuj11us.iso iso
    The ISO gets loaded via TFTP and seems to boot, but then an error message appears:
    Loading boot sector... booting...
    Lenovo Group Limited
    Invalid system disk
    Replace the disk, and then press any key.
    The Thinkpads come with the following SSD drive: SAMSUNG MZ7TD256HAFV-000L9.
    Anyone had luck with updating BIOS via PXE boot?
    We also have Thinkpads T430s. There the BIOS update ISO image loads, displays the menu, but when one presses "update firmware" then it freezes.

    I'm looking for some help connecting linksys IP Cameras to my home network to monitor my property when I'm travelling.  I used to do this with linksys WAPS, but since I've discarded all my old linksys networking and standardized on airport, I can't get these things working.  I know that I have to identify my camera through the DHCP table and set up port forwarding and there is the problem. 
    My network consists of 4  base stations set up in a roaming network - same network name and passwords.  I need to do it this way so I don't have to switch network when I move from one side of the house to the other, go to the cabana, or my shop in the barn.  The network works pretty well since I went to a roaming set up.  Good performance, yata, yata, yata.
    However, the roaming network requires the AEBS's to be set up in bridge mode, rather than sharing an ip address.  When the AEBS is set to  bridge mode, you don't see a DCHP table or have the ability to identify your IP Cam through the AEBS - and hence, no port forwarding. 
    I am able to identify and set up my Linksys IP Cam by locating the ip address on my FIOS router, even though, it's plugged into an AEBS.  I set it up, see the video, remove the ethernet cable from the IP Cam, restart - and I can't get to it from an AEBS.  In researching this, it appears, I should be setting up the AEBS to "share an IP Address", going to the DHCP table and identifying the camera's IP address and setting up port forwarding.  However, you don't see any of the DHCP or port forwarding options in Airport Network Utility when configuring in bridge mode. 
    I'm hoping I'm missing something here and that the solution isn't to set it up at the FIOS router level, but I'm beginning to think that's my only hope.  What concerns me there is that I should be able to see the IP cam on the network without port forwarding since I'm not coming from outside, and I can't even do this unless it's connected hard wire.
    I'd appreciate any insight into this that anyone might have.  I've hit the wall with what I know.
    Thanks.

    In a roaming network, your "main" router is the device that would require port mapping/forwarding to be configured in order to access the IP camera from the Internet. This router is also the one that would be provide the private IP address for the camera which you will want to be a static one.
    So as you described your network, the IP cameras should be getting an IP address or you assigned it a static one and this is the address that you would enter in the Private IP address (or equivalent depending on the router used) field when setting up port mapping.
    If you are not able to access this camera from the local network, then this should be troubleshot first.
