Problem with VGA output via CDM on XPS 12

When I connect my XPS 12 via a mini display to VGA to an external monitor, there is no problem. This changes however when I connect it to a beamer/projector. Then it is af if my laptop does not recognize that and I just cannot make it work. When I test the card on my macbook to friends, it does not work.

Do I need a special for this or is my laptop VGA adapter broken?

On Windows 7 or 8, I recommend trying the following:

-Hold down the Windows key and then press the button P to scroll through the choices of the external display

-First try the only projector choice and test it with Extend or duplicate

If that does not solve the problem, I do it with the following:

-Open Intel graphics and Media Control Panel (located in your Control Panel or system tray)

-Go in the multiple views section and make sure that the mode of operation is not defined for a simple screen

-   Active displays should show the total number of exits is connected as well (ex: 2 = integrated display + monitor)

If these two options do not work, you should remove your graphics driver and do a clean install of the latest graphics driver from the Dell support site.

Kind regards

    This problem may occur if the VGA card drivers are updated after the installation of Windows updates. I suggest to follow the steps below and check to see if problem persists.

    1. Click Start and stop in the search box, type Device Manager.
    2. On top, on the start menu, click on "Device Manager".
    3. In "Device Manager", double click "Graphics card" expand. "."
    4. Click on "display Matrox G200 G2 + / QUADP-PL/7 ' and click 'properties '.
    5. In properties, click on the "Drivers" tab and check if the option 'Return to the version' is 'active '. If so click on "Roll back" to restore the previous version driver.

    Note: If "Roll back" is greyed out, then see the article restoration of the system;

    Warning: When you use system restore to restore the computer to a previous state, the programs and updates that you have installed are removed.

    Important: try to restore your system to an earlier date when everything worked correctly.

  • Problem with analog output card FPGA 7851R

    Hi all

    First of all, I am a beginner in FPGA programming.

    In my application, I'm generating an analog voltage, for example 6V in a FPGA 7851R card is placed in 1033 PXI. I'm passing this tension to an another PXI with LabVIEW RT. Instead of getting a continuous 6V I'm getting some spikes with 6V. I enclose the screenshot of waveform which has obtained in PXI with RT the PXI card used is PXI-4462. I also enclose the code. Why am I getting this ears? Will there be another procedure to generate a continuous signal? Is there any problem with the acquisition?

    Please help me

    Thank you & best regards

  • Satellite A210 - ATI Radeon HD2600-problem with the TV via S-video connection

    I tried to connect my Toshiba laptop with TV (Philips LCD) via S-video, but TV was unable to detect the video signal from the laptop.
    I also tried to use a connection SCART TV through the reduction, but photo was the only black and white, no color.
    Last possibility is reduction use S-video to RCA yellow, but how do you know... But I really prefer to use 'pure's-video.

    I followed the step the manufacturer ATI and TV guide (first plug the cables, then switch TV, turn to the right in the TV menu, then the mobile source on, activation of TV as a secondary device (I have to force it, autodetect found nothing), press Fn + F5 (thing) and... nothing, black TV.)

    Where could be the problem?
    Cable seems OK, TV should support s-video and I get the right output in TV, I send the PAL signal...
    Maybe something with the Catalyst Control Center, I doubt.

    Can anyone help?

    Thank you very much.

    You use the Vista... Is this good?

    If so, the ATI Catalyst provides the TV option that must be activated.

    You should have an ATI Catalyst icon in the taskbar. Double-click on this icon.
    Then choose Advanced settings (second option).

    In the display options (Display manager) below, you will find the TV Force recognition option.
    Please check this option.

    Then reconnect the TV and try to use the FN + F5 key combination to switch to the TV.

  • Strange problem with analog output PCI 6251 and BNC-2110

    I'm controlling current source of third parties using the connectors of analog output on my card PCI 6251 and BNC-2110.

    The current source needs an input signal of 0.1V. I tested it using a battery, the potentiometer and the voltmeter, and by manually adjusting the voltage of power current works - current output with control voltage scales according to the specifications and is relatively stable.

    The data acquisition card works too - when I connect a voltmeter to the AO0 AO1, the measured voltage corresponds to the target with great precision value.

    But when I connect the current source of third AO0 AO1 data acquisition card, the measured output voltage drops and fluctuates. This applies to both channels of the AO.

    I wonder what is the problem here. I suspect it could be a matter of the grounding - the current analog control of the source is an entry with two floating terminals differential. I tried to return the switches FS/GS on the BNC-2110, but that makes no difference.

    Anyone knows similar behavior? Does anyone have any suggestions?

  • Problem with VPN connection via a wireless card broadband Verizon Cisco VPN air

    I can't access any device on my network via RDP or applications via the host file - forwarded servers from my 64 bit Windows 7 laptop using wireless broadband Verizon and customer VPN Cisco 64 bit 5.0.7.290. I can connect easily via a LAN wired connection from home using the same laptop computer and client VPN and RDP.

    The VPN client connects to the server VPN (easy VPN on Cisco 2821 router) on the broadband wireless connection (I can see it in the GPMC on the router) but it will pass no data. I can't ping anything in the field, or external IP address. When I try to ping the laptop, it drops off the VPN (completed peer connection).

    The laptop is a Dell M4500 running Windows 7 Ultimate 64 bit OS. The VPN client is stated, rev 5.0.7.290. The card internal wireless broadband is a QualCom 5620 (EV-DO-HSPA) system (Gobi 2).

    What must I do to get this configuration to perform and log as does the wired connection?

    The Systems Manager

    Post edited by: Timothy Carlisle recently I discovered that the Cisco 64 bit client VPN running on my Dell Precision M6500 (Windows 7 64-bit OS) was able to connect properly using the WiFi on my iPhone 4S (Verizon Wireless). It will also connect when attached to the laptop via a USB cable. Once I discovered this, I was then able to do the same thing on the laptop that spawned this discussion, by attachment for Blackberry "BOLD" from the boss after the download and installation of a new Verizon Wireless Access Manager utility that has allowed to select the device (Blackberry) for installation.  I think that enabled us to bypass the wireless cards Gobi2 on two laptops and the factory installed Dell Connection Manager software which was not compatible with the Cisco VPN 64 bit client software. As much as I fear here, this new method (hotspot of Smartphone and attachment) is the way to go for us and has solved all the problems of connectivity distance for us. Thank you to all who have contributed to this discussion.   Tim Carlisle

    The Solution to the debate has been captured in this Document: -.

    https://supportforums.Cisco.com/docs/doc-18721

    We fought with the same question for quite awhile before finding that there seems to be a default setting in the Verizon Access Manager software that plays well with the Cisco Client.

    In VZAccess Manager, select Options | Preferences.  Connectivity options, the default setting for "NDIS Mode - connect manually" was chosen.  Change this option to "Modem Mode - connect manually" seems to have completely addressed the issue.  We can now connect to the WWAN, establish a Cisco VPN session and have connectivity.

  • Satellite P300-150 - problems with HDMI output

    I recently reformatted my hard drive due to a nasty virus. I now put my old favourate XP Pro with service pack 3. Never had very well with Vista.
    I managed to find almost all the drivers, I think I need, but the HDMI does not work and I can't seem to find the HDMI for XP/Vista Manager only. XP is too old to support HDMI?

    Is their a fix or a piece of software that will lead the material in an XP environment?

    Hi markjj,

    Normally you n t need a special driver for the HDMI connection. It is only important to install the driver from Toshiba Web site viewing. After that, you can use the HDMI connection and switch between monitors when you press FN + F5. It s the same procedure as in Vista or other operating systems.

    So have you ever tried on XP HDMI connection?

    Test and give us some information. If it doesn't we can try to solve this problem. :)

  • Problem with the output of HTML5 video

    Hi, I have this course that I build. I need to insert several videos. 1 per slide. I managed to insert the .mp4 videos and when I export out of HTML5, the first video works fine. While all the other videos does not work. I just hear the sound but can't see the video. Also, if I go back to the first video that was working, it does not yet appear, but I can hear the audio.

    As soon as you have more than 1 video in the project, the first works well the first time that you see, and then if you go back, you hear only the audio, not the images. All other videos in the project does not appear, but you can still hear the audio.

    I use the latest version of Captivate 6, exit to HTML5.

    Thank you!

    Hello

    Welcome to the Adobe Forums.

    Can you please insert the video as the "video event" and then try to publish the HTML 5 output and display the output.

    Also can you please try with any other example of .mp4 file and then view the output as HTML5.

    Thank you
