Dell u3014 does not connect to any laptop (Dell XPS 13 / Dell Studio XPS 1340) via display port

Now, I received my u3014 dell monitor last night and did not, as still able to connect to one of my laptops.

I have a Dell XPS 13 (L321X), which has a port minidisplay outside and a Dell StudioXPS 1340, who was a regular on displayport.

Dell has included a mini displayport to displayport cable with the monitor and I tried this cable with two laptops, but no video appears.

I get the following messages with each laptop:

With the XPS 13: The monitor says "no displayport cable is connected.

With the Studio XPS 1340: "This monitor now goes in powersafe mode'.

The monitor works fine via HDMI and DVI, but obviously those who do not allow me to enjoy the maximum resolution.

The two laptops under windows 7 64-bit with video drivers of dell stock. I'm at a loss for what to do and would appreciate any suggestions/help someone.

Update: Dell sent me a new, replacement monitor. With this new monitor, I bought two cables:

Mini-displayport to mini-displayport to connect the XPS 13 to the U3014:

results: EVERYTHING WORKS as IT is MUST!

As soon as I hung the xps 13 on the monitor, the monitor acknowledged instantly and went at full resolution. The same is true when I tried to connect with the Studio XPS 1340.

So I don't know if it's a simple cable problem or if there is something wrong with the circuit board on the original U3014, and frankly, I don't want to try my new cables with her, just in case, and facing another headache.

Whatever it is, this fixes all my problems. Thanks for all your help to try to diagnose the problem.

    texhusky Hello, normally these problems are caused by a security/firewall software which does not recognize and therefore blocks the new versions of firefox. If please delete all the rules of the program for firefox to your firewall and let it detect the new version of the browser again.

    When I get something in the URL- google.com, localhost, http://127.0.0.1/ one bar the IP address, there is a fraction of a second flash, then the bar becomes empty and nothing has changed. It seems that Firefox is not even try to connect to the internet.

    Yesterday, everything was fine when I was running FF on Windows 7. After the upgrade to Windows Pro 8, Firefox has failed. I've updated for Windows 8.1, hoping for the best, but it's the same problem.

    I've walked by the firewall program, several times (the only race is the built-in Windows Firewall). Finally, I uninstalled Firefox, including all my settings, custom and reinstalled from scratch, twice. And even this version pure and clean Firefox does not connect to the internet.

    I am a computer web developer and would be happy to look at the log files or run a tool (Fiddler?) to see what happens at a low level, if I only knew where to look.

    john99, thanks for the links. I went through all (again), one by one. The last link kb.mozillazine.org/Standard_diagnostic showed me what helped. I've renamed "firefox.exe" to "firefox1.exe" and was able to use firefox.

    It made me suspect the firewall or malicious software. I ran a Malwarebytes full scan, zero problems detected. I have pored on the entries of windows firewall, the "Windows Firewall with advanced security" view and also the simple control panel view. The only mention of Firefox is that I continue to add and remove to allow firefox through.

    Here I knew what was going on, but for now, I can at least use firefox. How frustrating!

  • Does not connect to any wireless network

    I have an Inspiron 6000 with a Dell Wireless 1470 Dual Band WLAN PCI Card (in XP) and I'm having serious problems. When I got to my laptop it worked fine, and then he stopped just out of the clear blue. It picks up the signal and says it is connected but never load the page (i.e. the connection always times out). I fixed connections, restored and re-installed drivers switched to FireFox, tried to start in safe mode and still nothing (and I've not enabled on my router security). Oh, it connects. Any suggestions? I'm getting desperate!

    I have connected my itouch to my computer (usb) and itunes does not just I tried of recognized her. I tried to connect my both iphones and the same result - nothing.

    I tried all usb ports - nothing.

    What is going on??  I have the latest version of itunes and io in my devices.

    I search on google and it said something about apple usb driver, but I do not want to download from any site or don't know what the right answer.

    2. Plug in your device
    3. Locate Bus USB Controllers > Apple Mobile Device USB Driver.
      It is also possible that the device may appear under imaging devices, portable devices or other devices or as a device USB of MTB.

    Plug in the appliance. You should hear the telltale Windows sound device connection and a Division must acquire a new entry. This should be your device. If you do not hear the sound, and you have tried other cables so perhaps you have some Lint in the port that prevents a correct contact. Inspect with a flashlight and a magnification of class. If discovered gently teasing with something non-conductive like a toothpick.

    Or try the iPhone, iPad, or iPod not recognized in iTunes for Windows - Apple Support

    If not try a complete tear down and rebuild iTunes in accordance with the resolution of the problems with iTunes for Windows updates.

    Or try to go back to the last version of iTunes that has worked for you. See the programs installation of iTunes to download links. If you roll back to 12.3.3.17 to 12.3.2.35, for example, then you will also need restore the database in the manner described in the empty/corrupted after upgrade/crash iTunes library.

  • IPod Nano 7th Gen does not connect to my laptop

    I can connect my iPod to my old laptop but the laptop is dying quickly. I'm trying to connect my iPod to my new laptop computer and it instantly disconnects. I tried to uninstall Itunes and all the stuff on the help page provides than itunes. I don't think it's a problem with itunes, it takes my laptop. I have attached a picture for help. The "ADMINSTRAT" folder disappears after 2 seconds and then disconnects my ipod completely. (I tried several different USB leads and all USB ports)

    If you have already tried to uninstall iTunes, you must follow this procedure to completely remove iTunes and related software components

  • DMXzone PHP database connector does not connect with any string to localhost mysql

    I bought just yesterday 7 or more your extensions to retool Dreamweaver CC 2014.1.1 to manage the dynamic database sites.

    My localhost servers... I tried xampp and bitnami... I've already implemented with port 3306 & 3316 to manage 2 mysql servers.

    PhpMyAdmin has no problem to connect to one, PHPRunner has no problem, Navicat Premium has no problem and other tools.

    But your PHP database connector has yet to work for me I have try the normal mysql presets or use the option of a custom script to communicate with these localhosts.

    And the server is localhost, not FTP.

    The site is configured in the htdocs/mytestsitefolder to Bitnami / 5.4.38 - wampstack-0

    When you use the default connection wizard use localhost or 127.0.0.1

    port 3316, name of the comic, user, password.

    Then after playing with it some time, put Custom PDO connections, mssqli with no results, I see that you have not updated this connector for versions of Dreamweaver CC.


    Your connector will search a path named .../Dreamweaver/


    It's been YEARS since asked!


    And then when I look at the default connection for mysql method your extension uses only a mysql query that is now obsolete for many years.

    My host online uses php 5.5 and I do it at home on my development server.


    Or I have to use mysqli can't connect anything I build using your extensions.

    This must have been updated a long time ago.


    And using custom scripts to enable pdo connector you had better give just an example of what that look ALIKE.


    All PDO connection strings that work normally for me no problem do NOT work for the connector of your PHP.


    I need a solution as soon as possible or I will have to cancel this purchase.


    Thank you very much.

    And I'm happy to find an active support Forum where real techies answer!

    After that a conversation with thundermex, it turns out that the problem is - the user used a wrong localhost port in its site of DW configuration.

    Just some additional info, for all future visitors subject - none of our database tools are based mysql. DMXzone database tools are based on PHP PDO (http://php.net/manual/en/book.pdo.php), PHP PDO is a replacement of the extension mysql of old, obsolete, used in older versions of DW (http://php.net/manual/en/migration55.deprecated.php)
