T520: Unable to support more than 2 screens? (via the docking station)

All,

I have a problem, allowing more of 2 monitors. My T520 is connected to a docking station that has two outputs digital video that are connected to two monitors NEC.

For some reason any when I go on Windows | Display settings | It does not allow me to activate all three display at the same time. Can I have one) two monitors on the computer screen or b) + 1 monitor.

Whenever I tried to connect to the 3 screen, it automatically shuts the screen 2.

Other colleagues with T420 not experience this problem. The T520 & T420 uses the same docking station so I don't think that is the question.

My first thought is to update the video driver that I did but still does not. The T420 has a nVidia card while T520 has an Intel processor on board one.

If anyone has any suggestions that would be great.

Thank you

T520 with Nvidia Optimus can support up to 4 screens, while as the T520 with intel only the graphics card can support only 2 screens.

If you need more screen support on the T520 of yours, you may consider usb2dvi, eGPU, Vidock.

  • Collection of data from more than an instrument via the same labVIEW program

    Hello

    I have a program whereby I collect data on a scale of and save the data in the text file. Now, I need to collect data of three identical scales and save the data. I wonder if it is possible to do so in the same program? I mean how to manage three ports and save three different text files?

    I enclose the current program. Communication with the scale series and I use VI:s. thanks in advance for the help = VISA)

    This is easily possible with a single program, and there are several ways to do so.  I recommend the following:

    1. Take data from these devices in a separate loop (this could be in a separate - VI, as well).  These loops should be state machines if you can start and stop the acquisitions in a clean way.  This assumes that the instruments are on separate ports.  If they are on the same port, you probably want to use the same loop.

    2. Write to the file in a single loop.  This, too, should be a state machine.

    3. Queues to send data from the acquisition of loops to the loop of file I/O.

    4. Use still another loop for your user interface.  It must contain a structure of the event.

    To do this, you will need to learn more about the State machines and producer/consumer architectures.  Start with the help of LabVIEW, then search these forums.  There are a multitude of implementations of State machines and producer/consumer architectures.  If you have the time, I highly recommend you learn and to use the classes in LabVIEW (requires LabVIEW 8.2 or later).  This will facilitate your work in the long term.

  • Dc7800 BIOS update to support more than 2 TB of HARD drive

    Is it possible to update BIOS HP dc7800 to support more than 2 TB of drives? The PC is a SFF model with a processor E6550.

    I am aware that the BIOS must support UEFI to make this happen, but I can't find any (positive or negative) information about the dc7800.

    In Windows, it is possible to convert a GPT disk, which allows for more 2 TB disks, a second disk, but you cannot convert the system drive on a GPT disk, as this makes it unable to boot.

    So, if it is possible to update the BIOS, can someone please give instuctions on how to do this?

    I had all the and turn in circles and had absolutely no chance of achieving that goal.

    Hello:

    The first model in this series that can boot from a 3 TB HARD drive, I think, is the 8200 elite.

    dc7800 dc7900, 8000 Elite and 8100 Elite cannot.

    They can use > 2 TB drives for storage if they are in the GPT format.

    Here's how to know if your PC has a UEFI BIOS.  See page 5.

    http://h20566.www2.HP.com/portal/site/hpsc/template.BINARYPORTLET/public/KB/docDisplay/resource.process/?spf_p.tpst=kbDocDisplay_ws_BI & spf_p.rid_kbDocDisplay = docDisplayResURL & javax.portlet.begCacheTok = com.vignette.cachetoken & spf_p.rst_kbDocDisplay=wsrp-resourceState%3DdocId%253Demr_na-c02826744-1%257CdocLocale%253Den_US & javax.portlet.endCacheTok = com.vignette.cachetoken

    I have a dc7800 CMT and a 8200 Elite CMT both with the latest revisions of the BIOS.

    It is impossible to upgrade the BIOS in the UEFI in your model.

  • Satellite Z830 - I wonder if the motherboard supports more than 6 GB of memory

    Hey, I bought a Toshiba Satellite Z830-10w. It's a fine ultrabook.
    I wonder if the motherboard supports more than 6 GB of ddr ram.

    Have some of you tried it with a block of 8 GB of RAM Regand flemming

    > I wonder if the motherboard supports more than 6 GB of ddr ram.

    The chipset is responsible for the RAM
    Therefore, know if the chipset would support the 6 GB of RAM.

    Z830-10w supports the Intel HM65 Express Mobile Chipset and it should support the 8 GB of RAM

    To my knowledge the unit is equipped with a 2 GB internal RAM that is NOT removable.
    You can update ONLY one slot
    So one slot can handle 4 GB of RAM, and in this case the 6 GB of RAM are supported.

  • What can not run more than 2 screens on my Tecra R850?

    Despite claims that the R850 (with Radeon graphics card) will be 4 screens, the best I can manage is 2. I am trying to connect 2 external LCD screens and continue to use laptop as another screen (3 in total).

    I did a lot of research, and even if I can find a lot of people having the same problem, I can't find an answer. I tried to update the driver but that caused more problems than it solved. I use W7.

    Can someone tell me how to use more than 2 screens on a Tecra R850?

    Thank you.

    > I am trying to connect 2 external LCD screens and continue to use laptop as another screen (3 in total).

    In this case, you will need to use an external device, like the Dynadock

  • Photoshop Mix supports more than two layers

    Often when I composite that I find myself with three or more layers, as I often separate a base background and foreground elements image and add another cut in the ground, middle between. Are there plans to Mix support more than two layers, as I am currently limited to two making it useless for anything whether it is more cutting.

    Here are some features, I think that this application should be useful;

    • Add more changes to the version of the Tablet options to the phone version, they are useful and you give no reason do not include them.
    • As I asked here can we have more than two layers in favor.
    • Any chance of support for layer masks.
    • Can we have support for color curve adjustments.
    • Can I have more means to add and remove the smart tools from a selection of cutting is great, but sometimes I have a little precise painting inside and out around the edges.
    • Can we have the advantage of refine also included.

    OK so this all sounds rather negative but there are something does a very good Mix, that's why I'm so frustrated by his lack of other functions;

    • The intelligent cutting tool is the fastest way to get a reasonable cut I've never seen and is great, but as I say, I would like to be able to narrow down the selection by other means.
    • Moving and positioning of one single layer on the other is quick and simple and intuitive unlike photoshop Touch where the rotation of the image at the top has been slow and clumsy.

    This app could be great but at the moment it feels fully functional for work that it is apparently designed to do. Adobe do have plans to add features I ask here? Or other features, and in what time frame?

    Hello

    Your suggestions are really valuable for us and most of them are already on our roadmap.

    To answer your questions:

    1 Mix supports up to 5 layers since version 2.0 on iOS devices.

    2 flip layer is also supported for 2.0.

  • I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time.

    I have to remove the duplicate files, but having problems by selecting more than one file in the player at the time. How can I select multiple files at the same time so I can just delete them. I used to be able to do this in previous versions of Media Player, but this function seems now blocked or unavailable. The problem is this: through previous use of media player, it plays all my multimedia files several times whenever a device support has been added. He would try to save the files on my main drive, but since there is not enough room this would save the files somewhere else. This happened several times, I suppose, because when I upgraded my computer and a media scan was conducted he found duplicates of all my media various times of at least 6-8. I've consolidated since my plates on 3-disc multi to, but have now records duplicated hundreds and thousands of duplicate media files. Previous versions of Media Player would allow me to select all files and then delete them both of the reader, but also from my hard drive. So now I'm stuck with more than 300 GB of duplicate media I have to search line by line through all my hard drives to find each duplicate both, unless I can get media player to do what it can. Any help in this area would be appreciated.

    Hello

    1. did you of recent changes on the computer?

    2. is Windows media player files in double creation during playback of music files?

    To delete duplicate entries, click on another feature tab in the drive (for example the current playback), and then click library.

    If this does not remove duplicates from your library, you can use the Add to library dialog box to search computer to analyze a file on your computer the duplicate entries not valid-pointing. The player will remove invalid entries in your library that point to files that no longer exist in the folder.

    Complete the steps above for files that are stored in the hard disks.

    Method 1: Use the add to Library dialog box search for computers

    (a) start Windows Media Player.

    (b) press F3 on your keyboard to open Add to the library of the find computers dialog box.

    (c) click the Browse button to locate the folder on your computer so that your library contains invalid entries. Specify the location of the folder in the box look in.

    If you are not sure what duplicate in your library entry is not valid, you can add a path column to display in your library. Specify the folder on your computer that corresponds to the path not valid file displayed in your library.

    (d) click on the Search button.

    The player will search for digital media files and playlists in the folder that you specify and remove invalid entries in your library that point to files that no longer exist in the folder. If not valid in double entries point to other folders on your computer, repeat this procedure, specify a different folder every time.

    If only a small number of duplicate entries exist, you can delete those invalid manually by right-clicking on the invalid entry, and then clicking Delete .

    For large double-number of entries in your library (or if all your library is duplicated), it might be better to create a new library and delete the files.

    Method 2:

    After you remove the duplicate entries, run the troubleshooting of Windows Media Library settings to solve this problem.

    Open the troubleshooter in Windows Media Library

    http://Windows.Microsoft.com/en-us/Windows7/open-the-Windows-Media-Player-library-Troubleshooter

    Let us know the results.

    I hope this helps.
