No external display is connected?

I tried to reach my dell inspiron 1545 to an external monitor, my tv using a HDMI VGA cable. But it just says: no external display is connected, I tried changing the settings I think but nothing seems to help. I tried to go the windows Mobility Center to connect it but it still says the same thing. Is there something I can do?

Thank you very much

Here is an article on how to connect a laptop to a TV that focuses on the proper cables and runing (I don't see one that you use mentoned, but which means not necessarily that it's the wrong cable - maybe it's just that the article did not consider such a cable when it was written): http://www.geekwithlaptop.com/how-to-connect-laptop-to-tv.

Here is another article on the same topic, and once again, he seems to focus on using the correct and put cables on day of the dribers for yuur video card (which you should certainly do): http://www.techlore.com/article/10061/How-To-Connect-a-Computer-To-Your-TV/;jsessionid=1DE496C61344D19ABFF4EA7F26F289A3.

Here is yet another article that also goies how to set display settings in the control panel: http://www.labnol.org/software/tutorials/how-to-connect-laptop-computer-tv-screen-lcd-hdtv/2331/.

It seems to me that the problem is either the cable, you are usiing (most likely) or with the display settings on BOTH TV and laptop (don't forget the TV may need to be told to use the connection to the laptop using the options menu remotely or maybe controls on the front or the back of the TV - assuming that this is necessary with your TV (and it could be very welll)).  The setup of Vista is enough straightworward and changigg screens is relatively easy once the connection is established.   You must check in the right cable to use and whether or not the TV itself has settings that must be configured.  I would contact tech support of the TV manufacturer for help with these two questions - they can provide you with the answers you need or they can be of any help, but it's worth a try.

I hope this helps.

Good luck!

  • I can do: sleep when the lid is closed, EXCEPT when an external display is connected?

    Hello

    Please let me know if this is possible. Seems to me like a current need, but I can't find a way to achieve this.

    I wish that the laptop to sleep when I close the lid (battery / plugged - matter), except when I have a connected external display.

    The script is very simple, I prefer to work with an external display, so I don't want or need the lid is open. When I'm on the road, the "sleep when the lid is closed" is a desired behavior.

    Is this possible?

    Thank you

    Roee.

    (1) this function is available in the Apple OS, but not in OS Win.

    (2) but, you can set a custom power plan to do this, so when you connect an external monitor just switch the power around plan. It is the easiest way to get what you want.

  • System suddenly turn off when the external display is connected

    I have problem with my system. every time I connect a projector or a HDMI my system stays for a short time and shuts...

    Hello

    Thanks for posting your question on the Forums of community of Microsoft.

    1. The computer completely off, or only the monitor turns off?
    2. You get an error message or a blue screen while the system is turns off? If Yes, what is the exact error message you get?
    3. What is brand and model your computer?
    4. Apart to plug the projector, does this problem occurs in all other conditions also?
    5. What happens when you try to turn on the computer later, with a projector connected?

    I suggest you to check if the computer shuts down completely or only the monitor turns off. If the computer shuts down, the problem may reside with the graphics card driver that fits inconsistent or has become unstable or corrupt. Therefore, I would suggest trying the following steps and check if the problem persists.

    1. Open Manager devices by clicking the Start button, click Control Panel, click system and security, and then, under System, clicking Device Manager. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    2. In the list of hardware categories, find the display adapters and select the device driver you want to update, and then double-click the device name.
    3. Click the driver tab, click Update driver, and then follow the instructions. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.

    For more information, visit the below mentioned link:
    http://Windows.Microsoft.com/en-us/Windows7/update-a-driver-for-hardware-that-isn ' t-work correctly

    If you are not able to update the device driver via windows update, you can visit your computer or graphics card manufacturer's Web site and download & install the latest driver. Or contact the manufacturer of your system to do.

    Hope this information is useful. If the problem persists, please post back with answers to questions for assistance, we will be happy to help you.

  • rMbp mid-2014, external display with the quality of the retina

    Hello!

    I buy a Dell 24 "external display to connect to my rMBP with QHD (2 560 x 1 440) resolution.

    http://www1.euro.Dell.com/content/products/ProductDetails.aspx/Dell-u2515h-monit or? c = en & l = en & s = dhs & cs = frdhs1

    I have connected the screen to my mbp with the mini display / port cable supplied with the display screen. It works well, but I don't have quality of retina at all (the images seems good but the text is terrible)

    The text have a bad record as a retina screen, and it makes a big difference when I spend my retina display to the external display which is not comfortable at all.

    I though that this kind of screen was OK to view the retina... but I was wrong. I try to connect with minidisplay / display and HDMI! HDMI made was worse than minidisplay. The res in the system report show was good 2 560 x 1 440. I even try the hack to force with the patch, but always bad RGB render text...

    More important, I want to, it's having the same record as retina on the text and images. What external display can be good for this?

    My budget is 450-€500

    Thank you

    The size in pixels of the screen is not mean much: a small display to 2560 x 1440 pixels seems much sharper than a widescreen 2560 x 1440 pixels.

    Your retina Macbook has something like 220 dpi (DPI in English), the Dell screen only 117. If you want the same sharpness, you will need to choose a display with 220 dpi. But then, everything on the screen will look much smaller. Here is a tool that allows you to get the idea: http://dpi.lv/

  • Portege M700-130 + Portreplicator + external display

    Hello

    We have a Portege M700-130 with the PA3508E-1PRP portreplicator and have a problem with the external display (monitor) connected to the portreplicator.
    The OS is Vista Business. The external monitor is an EIZO S2401WE-GY.

    Now the question:
    * Can you just place your Portege in the portreplicator, start it with the key to the portreplicator and get an image on the external monitor to the connection of the operating system image without doing anything on your laptop? *
    It would already help us if someone with the Portege even and a portreplicator can give us his experience about it.

    Because we can't, but we have absolut want to achieve or better should. We have tested all the settings in the power and hardware configuration options. The point is: when the Portege gets started without portreplicator and is remplace replaced offshore in the portreplicator, then began with the portreplicator the external monitor goes black when loading of the connection of the operating system image. Only after that the laptop screen is fliped open, we get an image on the external monitor.

    Help or an answer, I'd be very appreciated. Thanks in advance!

    Hello

    One of my friends has tested this on the Portege M700 Vista OS.
    It connected the external monitor using a VGA (analog) and DVI port.

    It seems that it works as you suggest in your ad.
    The Portege lid is closed and connected to the external monitor.
    You do not need to touch the Portege M700. He should start by pressing the key of the duplicator.

  • Satellite A200 - 23 k - view corruption during outdoor display is connected

    HY everybody :)
    If this problem occurs in 95% of the time when the external display is connected. Picture looks like it has some artifacts and color everything is blurred. ATI tools does not detect objects, and the system reboot or wake after sleep "solve" the problem.
    BIOS is the last, ram has been upgraded from 1 to 2 GB, there is no difference which is the OS or drivers are used (official or modded).

    EDIT: Not long ago I started playing battlefield2 and this happens often in this game, but in no other (HAWX for example)
    Edit2: this display corruption occurs only on the main screen, never on external.

    So any ideas on how to solve this problem?
    Thank you!!

  • iMac 5K (2016) will not all wake up with connected external display

    I have an iMac 27 "5K nine. My first Mac from Windows - it was a world of frustration and then most of the things I re-learned or found of alternatives for, I have a major problem of the iMac not wake from sleep. It took days to change things and we cut the field down to discover is an external monitor at the origin of the problem.

    I have a LG 23MP75 IPS monitor hooked up to 90 degrees. This is a debugging, screen bash and the cat. So I develop sites on the main iMac screen in the Sublime editor and also check the sites in the browser, and then on the external I Inspector chrome, terminal and Skype/cat stuff. When the device is connected, it works well, no problems. If she goes to sleep for a short period of time like 30 minutes or less, he wakes up. If he goes into a deep sleep (hibernation?), he don't wake. Sometimes holding the key ctrl + p + r, cmd and press work but mostly not, usually I have to pull on the power cord! for a restart. Heart-wrenching. The only solution at the present time it unplug the HDMI until I go home every day.

    The external monitor is connected through a HDMI cable that is routed into an 'active' HDMI mini-Display port adapter. I was told that the adapter is active is important after I had one active and bought assets to try to solve this problem. I read that the removal of the hibernation file may contribute to allow OS x to replace but I opened it instead and it is empty so not corrupt (sudo rm/var/vm/drag).

    If I stop and restart, the login screen is badly laid out, it has mirrored screen not extended display which is how it is implemented. See the images to compare. This makes me wonder if part of the problem is OSX being unhappy with the configuration of the monitor outside being connected?

    Here is the screen set up the config so you can see that there is nothing out of the ordinary:

    There is no strange configuration, the machine was brand new from Apple themselves, by default on the box, no restoration or something like that as I'm new to Mac.

    Can anyone offer any suggestions to fix the problem so I didn't either unplug the cable or the stop (which brings me to see the connection in horrible mirror every morning)? Any help would be greatly appreciated.

  • MacBook - problems to connect the external display w

    I do a lot of presentations (Keynote) to Mac external displays at events.

    The new MacBook (12 ") is quite often problems, so I have to carry a MacBookAir as back-up in case where.

    Problems can be no image at all, or two images (like 70% Keynote + 30% of office) and with spikes.

    It doesn't matter if I use HDMI or VGA. And Yes, I know how to set the resolution in the workplace sometimes that the problem is solved by adjusting the resolution manually, but then the Macbook can jump to the resolution which does not by itself during the slide show...

    I think that the problem only occurs when I have to go through a device such as a split, or when there is a lot of tech back stage.

    Anyone having problems of this kind with the MacBook?

    Any ideas on what is wrong and how to fix?

  • Re: Satellite A660-10W - connection external display with HDMI cuts sound on

    When I use an external display via the HDMI, it mutes the sound of the laptop.
    It's OK because the external display has a headphone/speaker output jack.

    However, when I close the external screen (which I use for movies only) and to use the laptop only, the sound is cut all the time that the HDMI cable is connected.

    I can't hear sound - by harman/kardon speakers or headphone - when the HDMI cable is disconnected (if the external display is turned on or off).

    Is there a way to allow me to have the choice and use her laptop - even when the HDMI cable is connected - in order not to keep plugging and plugging on?

    Thank you

    It is clear.
    If the HDMI cable is connected, then the digital output is defined as audio output by default and therefore you do not hear the sound of the internal speakers but on external monitor speakers.

    You need to change the sound settings.

    Go to control panel of-> sound-> reading tab and set the speakers to laptop as default.
    Then you should hear sound from the speakers for laptop!

  • Bad resolution of Qosmio G30 - external display via the HDMI connection-

    Hello! This problem makes me crazy, please help if you can...

    I just bought a G30-102 and I am trying to use it with an external display via the HDMI connection. The problem I have is that the native resolution of 1920 x 1200 cut the edges of the screen and the quality looks terrible - its almost as if the entire screen is enlarged. I tried with a BenQ FP241wz initially (1080i is 1920 x 1200) and the Toshiba helpline could not find a solution either - even after painfully reinstall all the drivers, etc..

    Its been going on for so long, I thought I'd try it out with my HDTV instead, just to be sure it wasn't a monitor problem. So I tried with my Toshiba 32WLT66 - and come to find that it has exactly the same problem.

    All the display settings appear to be correct and the G30 is convinced that the result is correct, so I have now it is - don't you think not that this is a problem with my HDMI port?

    Please help, I'm a designer, and it is essential that I use the machine on a large screen. If it is a hardware of the G30 problem, I need to talk to Toshiba immediately replace or fixing.

    Hello

    I tested the Qosmio G30 (HD-DVD) with my LCD TV using a HDMI cable. Everything worked perfectly. As a first step, I put 1080i value in the settings of the BIOS and after following the instructions in the HDDVDGuide document under http://support.toshiba-tro.de/kb0/TSB6A01LH000LR01.htm

  • Satellite P750 - unable to connect an external display via the VGA port

    Hi all

    My problem is the following:

    I tried to connect my P750 (running on W7 x-64) an external display using the VGA cable port. Unfortunately, these devices recognize my phone. Laptop does not recognize the external display, you can see in the graphics settings as additional display, but the screen shows "no signal".

    The computer always identifies the screen correctly, so it seems that there is communication from the screen to the PC, but not the reverse.

    This has been verified with 3 separate screens and television - still the same. All the screens work properly with the other PC.

    I already have:

    -try to play with FN + F5 / "windows" + buttons P - no change
    -install the latest drivers BIOS and video site Web from Toshiba - no change

    Suggestions how to operate? Is it possible that the VGA port is faulty?

    Thank you in advance.

    Hello

    You have the same problems with a HDMI output port?
    Usually, you don't need to change anything to get the external monitor works.
    Press Fn + F5 several times until the monitor RGB (VGA) was selected
    Since you can choose an HDMI output too, you should pay attention to this option.

    Have you tried to change the resolution before using the Fn + F5?
    It s worth a try

    Last but not least, you could set the default BIOS (press F9 BIOS and save the changes by pressing F10). But I don't very well if the BIOS contains some parameters of port RGB (VGA) m

  • Impossible to connect an external display

    Hello

    I have a MacBook pro 13 "with the latest software and updates to the OS. I tried unsuccessfully to connect my laptop to an external display, a Dell P2414H.

    Unfortunately, this screen has a hdmi connector. I used the VGA cable with a VGA adapter / HDMI to connect to my Mac. I chose the VGA output on the screen, but the MacBook has not detected the screen. I can connect the external display with the laptop of a colleague who is on the 8.1 Windows / Ubuntu LTS 14.04 (dual boot). Thus, the HDMI, VGA cable adapter and the screen are ok because they work on other computers.

    I also tried to plug in my MacBook at home with my external screen Asus (hdmi connection) and my Sony TV (hdmi connection). Everything worked well.

    How can I solve the problem of connection with external display Dell?
