MBP: monitor detected but no image except by VGA

I have a MBP of Mid 2012 running latest El Capitan.

When I connect to an external monitor, it is detected correctly in views (exact name, resolution, etc.), but the monitor doesn't detect any image from the portable computer. I tried the DVI - D and DisplayPort with various cables and monitors with the same result, but a picture appears if I connect to VGA. It started in the past week.

The built-in display does not work normally.

Looks like a hardware failure in the computer DisplayPort connector laptop, as the pins are worn or something?

Any other ideas?

  • Tecra M5 - external monitor detected but not image

    Hello

    I just bought Tecra M5 for use with my external NEC monitor. However, regardless of the configuration, I try I get no image on the monitor. The LED on the monitor indicates that it receives the signal from the laptop but the monitor remains black pitch. The monitor works obviously very well, I just disconnected from another laptop.

    I tried all possible settings in the nVidia control panel, but without success. I also changed "Power On Display" in the BIOS "Screen LCD + Analog RGB" but no luck either.

    I have v.3.70 of BIOS and graphics card drivers v.7.15.

    Can anyone help?

    Thank you

    PS When I press Fn + F5, I have no options to choose from, unlike the other FN +... combinations. I don't know that it should be everything, but it is perhaps worth mentioning.

    Also when I select only 'use a view' of the nVidia control panel and select my NEC monitor in the list, the monitor turns on and the light turns green, but the screen is still black. Like I can't accept changes the output switches to the computer screen after a few seconds.

    Hello

    I think you should test with the preinstalled Toshiba operating system.
    After that the laptop was recovered, connect the external monitor and use the FN + F5 in order to detect the external display.

    Hi Redbaron666,

    Have you checked if the game works the clean boot?

    I see that Rollercoaster Tycoon 3 is not compatible with Windows 7 which could be the cause of this problem:

  • Windows 7 photo viewer will not display all images, except in slide show mode.

    I use a laptop computer with a monitor connected via a dock of the USC.  Everything worked fine until today.  When I use the monitor as the only display, windows 7 Photo Viewer does all the images except in slide show mode.   To be more precisely, after clicking on the file, Photo Viewer displays "loading".  If you wait long enough, the image appears later, but if you move or the zoom, the image window disappears.  If you go to the slide, the image appears immediately.  However, if I use my laptop screen, or both screens in extended desktop, Photo Viewer works very well.  Basically, as long as the screen of the laptop is off, photo viewer gets confussed and cannot function properly in slide show mode.

    I read through existing similar questions, but impossible to find a solution.  Help, please!  Thank you!

  • External monitor works but integrated screen is not

    Hello

    I have a model of Macbook Pro 13 of the retina (mid-2013) .

    A few months back the display has stopped working, but when I hooked to an external monitor everything worked as expected except the screen of course.

    I took it to the service center and a descent computer repair shop and they both said that display connection with the logic board is fried and they need to fix the logic board that retina display is fine.

    The price they are quoting is about $ 900, which is not fair.

    The logic card cannot be repaired?

    anyone else in a similar situation?

    If all the otherwise failed I think I'll delete the entire display of macbook. Someone knows how to do this?

    Thank you!

    Welcome to the CSA!

    Because of the tiny parts and connections on a logic board, repair is usually not an option. I don't say it can't be done, but it's hard to find someone who can / will work on resolder delicate bits on a LB (redistribution) without making a mess of labor law.

    You live in the United States? If so, ask about a "repair." Instead of working on the computer in the Apple Store, they send to Apple rehabilitation center where they pretty much fix everything what they find wrong inside (with the exception of the display unit itself) for a flat rate that is much lower than the cost that you quoted for repair in the store. I believe that the current price for this service is approximately US$ 315.

    The only downside I see is that the repair takes about a week, largely during the transportation to and from the depot.

    If you are not in the United States, ask anyway. I don't know what Apple has implemented for this kind of repair outside the United States.

  • How to use an external video monitor for just the image being set?

    I would use my external HD monitor as a single image display in Photoshop that I adjust

    the image, similar to what I do in Final Cut Pro to display full screen of the external video monitor. 

    Anyone have to do this?  rather than simply dragging the full interface of the PS to the external monitor,

    and stretching on to fill the screen on the larger screen?

    Duh!  Now I feel real stupid.  The solution was very simple for me, using my MacBook Pro, Intel processor

    OS 10.8.5, with outputs of Mac screen, through to DVI converter, feed my Dell HD 1920 X 1200 monitor.

    There is no instructions for it, but I just click and drag in the "document" tab in the public Service

    Center the window interface and drag it on my external monitor.  And the controls, settings, et al.,.

    work therefore monitor on the image in the external hard drive.  And Mac do rotations display preferences

  • Monitor problem - gray without image areas

    Lightroom does not display images on two of my monitors.

    I just bought a beautiful Dell U2711 monitor, configure it as the main monitor, and is connected via display port.  It's on an ATI Radeon HD5770 (1Gig) card, with two other monitors (which use the DPI port).  Operating system is Vista 32 bit. (Intel Quad CPU @2. 4 GHz, 4 GB of RAM 4 carrots.)

    How can I make Lightroom 3 show photos and not gray boxes?  LR only displays photos on screen 3 (a smaller Dell).  All I get on the main monitor (2) and the third (1) monitor are gray boxes.  I tried the "secondary monitor" settings but they still don't work - get only grey boxes on the other two monitors, no image.  Not exactly what I was hoping.

    BTW - Lightroom 1.4 works and shows pictures on all three monitors, is that version 3 that has the problem.

    Hope someone can help me here.

    Your monitor profile is corrupt. Switch monitor profile sRGB or better yet re - calibrate the monitor using the [hardware/software designed.]

    I now use 'Chrome' browser whenever I want to visit YouTube,
    I do not wish to use 2 browsers and I want to stay only with Firefox.
    I tried several solutions without success.

    YouTube is generally serving Firefox users the HTML5 player now instead of Flash player. You can check that one you get by right clicking on the drive and runs the inspection of the line at the bottom of the context menu. As patches are probably completely different for both players, it would be useful to know the problem.

    There is also an add-on, you can use to switch the player if you want to try it (so it is easier to do using built-in YouTube settings): https://addons.mozilla.org/firefox/addon/youtube-flash-video-player/

    Since it's Windows XP, it's maybe the old problem of the "drive letter".  Being a Mac user, I don't know the exact procedure, but try changing the drive letter of the iPod.  Maybe that's how
