Equium A100: Nothing on the internal display, but on the external monitor

For some reason, my laptop has forgotten that he has a screen attached to it.
I can see everything if I attach an external monitor, but there is nothing on my LCD screen, even if it is on and lit. It is only black.

I tried to update the display drivers and even the BIOS, but neither one of those who helped.

And it's not my screen brightness, either - which does not at all. It's as if my screen has just been removed from the system. Help, please!

Are you sure that the display is not faulty? As far as I know if your laptop is not connected to the external display the home screen Toshiba must be indicated on the screen of the laptop.

Start the laptop without external screen and wait a few minutes. If you think that the operating system is running correctly, try to use the combination of keys FN + F5 several times to see if you get the image on the screen of the laptop.

  • Equium A100-306: cannot set resolution 1440 x 900 on external monitor

    Has anyone encountered this problem? I searched the web without success and it doesn't seem to be all programs that will force the graphics in this resolution. Is only shown for linux-based systems which have a complex solution for this. I have a new A100-306.
    The maximum power that I get is 1280 x 1024, which is ok but lack just that final freshness.

    I think that the solution will be an update of the video bios but it is an update from the manufacturer and not a processor intel, a? As the machine is new he does not appear to be updated again. If anyone has a solution please post, if not Toshiba please quickly with an updated driver.

    Thank you

    Hello

    I read several candidate here in the forum on different screen resolutions that are not available for the external display.
    Fact is, if no resolution of the screen is not available, then the graphics driver doesn t contain the display resolution in the list. In this case you must use the common screen resolution which is available. But this isn't a problem.

    Furthermore, each screen support a clean resolution. I mean the screen with a resolution which is the best for this view. Then the screen and the image is very clear, and as you said crisp.

    On my screen I can pick several display resolutions, but the best resolution for my monitor 1280 x 800.

  • Re: Equium A100 - 2 L - the search for the replacement of HARD drive

    I inherited an Equium A100 - 2L (PSAAQE) of my brother, but he kept the hard drive damaged in the hope of saving its data on it. Can anyone recommend a hard drive replacement, and I need one any attachment or additional connector?
    Looking at various Web sites, I'm puzzled by this disc to buy regarding dimensions (SFF, 1/8 H etc.)

    Thank you

    Hey Buddy,

    No, you need a t n pregnant additional or connector. The caddy HARD drive you need you can use old HARD drive and the connector is soldered to the motherboard. So when you replace the HARD drive, you need only one new, what s.

    Equium A100 has already SATA interface that means you buy a HARD drive with SATA interface, but it of not important if she s SATA1 or SATA2 interface because the two standards will work (SATA2 is compatible downgrade to SATA1).

    So just buy a * 2.5 HARD drive with SATA interface *. Also there is no capacity limit, 500GB or more should work and manufacturing is also independent.
    Just look at some online stores and buy a HARD drive with good price / performance. :)

  • Satellite M30X-111 screen does not display anything but the external monitor works

    My laptop just screen does not display anything (like when the computer is turned off), but when I connect the external monitor, then the desktop is displayed on this screen. I tried to recover the laptop using the recovery disk and it worked again, but today, it stopped working again.

    Again, I must plug the external monitor, and after I tried to restart, I continue to pressing F8 but the startup mode is not come, the noise of when you press a button for too long beeps, however, the monitor of the laptop working again.

    How can I solve this problem?

    What do you do? You want to recover the laptop?
    If Yes, you n press any F8 but you will need to boot from the recovery CD by pressing the C key immediately after starting the laptop.

    But this question seems that you have accidentally switched to external display.
    I recommend checking the Fn + F5 option. This combination allow you to switch between the display and the external monitor.

  • Equium A110-252: the display on the external monitor resolution

    When I connect my LCD TV screen to my new satellite A110-252 using the external monitor port does not fit the image of the (too big) TV screen.

    I've tried everything on orders for establishment of TV screen but no joy. Surely, there must be an option to fit to the screen on satellite? Can anyone help?

    Thank you Perry.

    Hi there, you are using the external monitor port or the S-Video? Unfortunately, if you use the S-video port you can hold all of Office on television because it is technically impossible (without deleting the lines).

    TV less than number of rows than a computer monitor: PAL = 576 visible lines, NTSC = 480 visible lines except if you can pass in 640 x 480 mode 800 x 600 is the best that you can use to display an image on the TV.

  • Portege Z830: I want to disable internal LCD and use only the external monitor

    I have a Toshiba Portege z830.
    I use my laptop in "Extended desktop", mode with an external monitor, which is the main display.
    In this mode, the two screens are still on, but I want the built-in LCD screen to be opened only when I use it.

    Is this possible?
    Thank you.

    Hello

    In my opinion, this is not possible.
    In extended mode, you use and display internal but extended and the long part is visible on the external monitor.
    In such a case its any that your external monitor is set as main display.

    If you want to use an external monitor only, you can only export the video signal on external monitor by pressing FN + F5

  • How to find out the resolution of the external monitor max on Satellite Pro A100-02Y

    I have a Satellite Pro A100-02Y.

    I want to launch an external monitor but don't have any idea how big a monitor will deal graphics drivers. How will I know?

    Thanks for any help.

    Hello

    You should keep one fact in mind that the available screen resolution depends on the graphics card and the graphics card driver.
    If I'm not mistaken, you can find the max somewhere graphics card resolution information in the user manual.

    But note; If the graphics card driver does not support you favorite resolution then you will not be able to use and to choose!

    In the properties of the graphics card, you can find the available screen are supported by GPU driver resolutions.
    Usually these resolutions could be used on the external monitor, but only if the external monitor takes care of everything.

    Best regards

  • Cannot get T500 to display on the external monitor

    Hello
    I'm running Windows 7 on a ThinkPad T500 (type 2082.BSG), and I'm having problems after have recently updated my display on the Lenovo site software (read the list of installed software, I think that the installation of the software that is the cause of the problem is "ThinkPad features video [AMD switchable Graphics (M8x)] for Windows 7 [32/64 bit] ') version 8.752.4 - 101022 a-107489C-Lenovo). Before the update my computer has guessed what display is active (laptop screen or external monitor) and used the active display. For example, when the laptop is docked and the cover closed he used the external monitor. After the update when the laptop is connected and the lid is closed, I can't display on the external monitor. I have to open the lid and use the Fn + F7 to get the display on the external monitor. Can anyone tell me please what settings should I use to get the old behavior.

    Kind regards

    The previous is an old post, but as there was no response, and I recently solved the problem, I write in case someone else runs into the same problem.

    After having encountered the problem I restored the factory default driver (which does not show the problem). However, lately I received another message to the effect that it is recommended to install Lenovo "Thinkpad video Features (AMD Switchable Graphics...). ...". I installed the software but the problem described in my original message reappeared. However, this time, the software of (the age AMD) had a "driver update" option and my video material is correctly recognized and the correct driver has been downloaded from the AMD website, after which the problem described in my original post disappeared.

    Kind regards

  • Turn off display when you use the external monitor R61?

    Hello

    I have a ThinkPad R61, which I use with an external monitor.  Somehow, I had in place for months with the laptop out of the screen and the monitor on.  I've used today at a meeting to feed a projector, selected somehow dieting Fn F7 of presentation such as the screen and the projector are-as I wanted - then home, re-installed with my external monitor and cannot find out how to turn off the display on the laptop.  The selections under Fn F7 do not allow this combination.  I tried the trick you offered, Fn F3 to turn off the display, but it turned out the two views.  (Now, how can I reverse this setting?)

    It sounds like a requirement of switching every day, but I can't find a clue in aid of ThinkVantage, manual mini, on the website, etc.  Thank you

    WaynO salvation,

    After pressing Fn + F7, click on manage plans... to open the Director presentation window. Then click the new... button. You should be able to put in place a system to only display on the external monitor. After setting up, make sure to check the box in the column Menu Fn + F7 to have your new schema appears in the menu when you press Fn + F7.

  • Satellite P300 - display resolution incorrect if the external monitor is connected

    I installed the latest ATI drivers that I downloaded from the Toshiba site. Max screen resolution is 1680 x 1050. This resolution no longer exists after the connection of the monitor.

    Also, I can't set the correct resolution for the LCD display of the laptop more.

    How set up the screen, so that the monitor displays a clone of the LCD screen for laptop and find the correct resolution?

    Hello

    > Max monitor resolution is 1680 x 1050. This resolution no longer exists after the connection of the monitor.
    Please understand that not all possible solutions are supported by a graphics card chip or a graphics card driver.
    If one of the parts mentioned would not support this resolution then you will not be able to choose and use the external monitor!

    In your case, I recommend the manual of your laptop.
    There you can find a list of available external resolutions and supported.

  • Black screen after on native screen only hp logo, but the external monitor is ok

    Hello everyone. HP Pavilion dv9700.

    The graphics card has been burned, and I ordered the new motherboard of eBay and replaced it.

    The problem is:

    When I turn on the unit, the native screen flashes once the HP logo then it becomes black. If I unplug the video cable and connect the external monitor, it works perfectly. The same thing with remote access. I start with a blank screen, and I can connect remotely to the laptop.

    What did I miss? where to look for potential problems?

    the problem has a link between motherboars and display.  I could see the screen by moving the display cable. Maybe it's because the poor quality of the motherboard, I bought

  • I can't enter the bios using the external monitor

    Hello, I use Dell Inspiron n4010 for the last 2.5 years. My laptop monitor stopped working that's why I bought an external Dell monitor... Its works fine but I need to install the windows now... Unfortunately, I cannot get into the BIOS of the external display and can not change the device to initialize DVD ROM.

    Please can someone tell how to enter the BIOS using the external monitor (I put it as a main monitor, but it still does not work)? The Monte screen after windows starts... Is it possible to get it back? Help, please...

    Yes - I know - it's what I'm trying to show you how!

    If you follow my instructions in my last post, you will see nothing for the "six seconds".but the startup process stops at the BIOS screen and FN & F1 or F1 key will rise from the dead internal to external monitor.

  • HP Envy X 2 (15-C001dx): HP Envy X 2 (15-C001dx): question seeks to use the external monitor

    I have a brand new HP Envy X 2 (15-C001dx) with Windows 8.1. So far, it works fine by itself. I tried to connect an external monitor to the laptop using an HDMI cable from the laptop to a LG L246WPQ screen. The problem is that 10-15% of the left side of the content portable screen does not appear on the external monitor. Missing from the external display is the word "Start" in the upper left with roughly 2 columns to tiles. This occurs in the two "dual display" or "show only the screen 2" modes.  It's using a resolution of 1680 x 1050 times the cell phone and the LG appearing in support. Using the touch screen on the laptop I can scroll tiles to the right and see the missing columns at the far left. The information displayed on the external monitor begins as far left this screen will be displayed. In other words, there is no black and white on the left box. Except for the missing information on the left side, from the rest of the external display content seems fine. I have updated video driver of the laptop at the latest on HP.COM.  No change in behavior. I tried all the options I could find on the LG OnScreenDisplay, but nothing does the display not better. I've seen complaints on some forums that some "DPI" support added in Windows 8.1is causing many grief monitor for some people. Who would have something to do with it?

    This sounds like a video driver problem?  Something incorrect or incompatible with this LG monitor? Suggestions on other things to try?

    Thank you

    @outback ,

    Hello and thanks for the display on the HP support forums,

    The first thing I would try this question takes the hdmi cable and plug it on another monitor or a TV.

    If the same problem exists then LG issue.  If the same problem occurs on other screens or TV then looking at a resolution problem on the output of the system.

    Even if you can be able to higher resolutions sometimes native resolution will eventually force you to lower it.

    I have two screens at home who can manage resolution 1680 x 1050, however the native resolution is less than that.  and according to what I connect to the screen will depend on what I can get away with.

    Here are some links that you can see and which can be useful.

  • Tecra A10 - 1LL - connection with the external monitor

    Hello

    I have a problem with my laptop Tecra A10.

    When I connect to an external monitor to the laptop I have to manually switch the screens because external shows nothing. When I disconnect the monitor I have to pass the screens manually with FN + F5 because the internal display shows nothing.

    My old laptop (Tecra A9 (PTS52E-0E702NGR)) is the poster automatically whenever I connected or disconnected an external monitor.

    Anyone has an idea why the A10 light automatically as the old notebook? Maybe it's the only spot in the preferences of the display driver that I don't see right now. :-)

    Hi SilverWizard,

    What happens if you try to switch on the external monitor using the options of display driver, or that this combination of buttons don t work?
