    With the tv connected that is likely being seen as the primary display. You will need to go into the Control Panel>Display section to correct this there. You will want to see if the lcd on the laptop is even being detected as it should.

    Often a tv will simply replace the default monitor even on a desktop once you have that configured rather then ending up with a clone desktop. Laptops and other portables are not really geared for dual displays until you configure things manually.

    Okay, I did what you said on Windows 8...I got to the menu and it does DETECT my Laptop's monitor, it detects it. BUT I can't apply it for some reason. I even updated my Intel HD Graphic's drivers..
    Like, the "applu" button is still greyed out...

    You may have to shutdown, unplug the tv, and then see if you get the normal display working on the built-in display itself in order to set that as default.

    Apparently you are not seeing the cloned display you would expect but tv replaces lcd once detected. That would explain why that would be greyed out.

    Now that you updated the laptop's display drivers you can give that a try to see if you get anything without the tv connected. It should default back to the laptop. But the only way to find out would be giving that a test.

    It didn't work... It still detects it, but it does not let me apply the settings. I still have no display on my laptop, just my TV...

    It could be your back light is gone on the laptop. The display is still being detected while the screen will remain black for that reason.

    If the post screen is dark as well as the loading OS screen you wouldn't be able to go into the bios setup and try jump starting the display by switching from integrated to PCI and then back to integrated without the tv connected. No post screen at all would suggest the back light as the problem.

    Windows 8


    I also have the same problem on a brand new Dell Inspiron laptop. I have it set up to dual boot and the Windows 7 OS works flawlessly. However whenever I boot into Windows 8 CP I get the Post and it starts to load Windows 8 and then just a black screen.

    If I then connect a monitor to the VGA output I get video on the external monitor. Nothing on the laptop display and no option to do so.

    When I go into Control Panel -> Display and try to Detect my laptop display, it doesn't even show up as an option. Just the external monitor.
    I tried updating and downgrading video drivers, using a mix from Intel and Microsoft; but still no option to use the laptop display.

    Welcome to the forum!

    This problem of yours looks serious.

    Try one of the drivers mentioned here: Intel HD Graphics 2000/3000

    They seem to talk about intel hd graphics 3000, if this is your graphics card. Keep an eye on windows update and intel's drivers website as they constantly release new drivers and fixes.

    Good luck

    HAHAHA! I was in the same situation. Just close and open your laptop when it goes into the black screen.

    The problem with Intel HD graphics cards on windows 8 is that they don't detect the laptop display. Your backlight isn't broken, the driver just doesn't detect the display. Some users found that if you close the lid (causing it to go to sleep) and opening it back up the display will work again. Although only some users were able to get it working.
