• Using Late 2009 Imac as external display for PC with display port 1.2

  Hi all

  Thanks for your time.  I searched for a definitive answer to this question before I go ahead and make a purchase.

  I have a Late 2009 Imac 27 ".  I would like to use it as an external monitor for my new PC, which is a graphics card EVGA GTX 970 with a displayport 1.2 output.  I'll be able to use a DisplayPort / mini displayport cable to connect to my Imac to use as an external monitor for my PC.

  The Imac doesn't have the speed I need for photo editing but I like the contrast and the size of the screen offers.

  Any input would be appreciated!

• P2415Q - no display on DVI, HDMI. No menu. Worked perfectly for a month on the display port

  Line of reason: Dell P2415Q. After a month, works perfectly on the display port, no display on screen Display Port or HDMI, no response to the menu buttons, backlight and power ON but no picture on the screen.
  
  

  Description of the problem
  

  The monitor worked out of the box for a month using the mini display port display port cable supplied with the monitor, which was plugged into my XFX 7970 and 7950 graphics cards. It supports 4K at 60 Hz and has been exceptional for photos, videos and games. Wednesday, the monitor no longer works, no picture or menu is displayed on the monitor. I plugged my old monitor to help diagnose via DVI graphics card even. When I press the power button on the Dell P2415Q monitor, the power LED lights up and the computer detects the monitor (as shown in the menu of the windows screen resolution). He defines as a secondary display but the screen remains black, I see the light power and backlight is turned on. No power save mode popup doesn't appear on the monitor, when I press the buttons of the menu there is no response from the screen, it stays black. I repeated with an HDMI cable, the same problem occurs without intervention or image. I repeated and disabled crossfire (which allows graphics cards to run independently) and tried the second graphics card without response. I tried the HDMI cable I used on my old LG monitor, it works well. I tried to connect a laptop on HDMI to the monitor too, no response from the monitor. I've exhausted all the tests I can think, I guess I'll have to return to the screen for repair or replacement under warranty. A question to the community - and dell rep is there anything else I can try / to make this work?

• U2412m continues to go to power saving on the Display Port!

  According to the title, the monitor works fine on DVI - D, however, when you use the Display Port, it will never get photo.

  I unplugged all the cables and only connected 1 monitor to my computer. When I plug the Display Port, the monitor recognizes the cable, and he goes to sleep. However, he never wakes up and there are always connected via the Port display power saving mode.

  I have connected my second monitor, and Windows by virtue of the resolution of the screen, I can see the two monitors that on DVI and the other on the display port., but the display port we'll never come back to life.

  My problem is similar to this: http://en.community.dell.com/support-forums/peripherals/f/3529/t/19534915.aspx

• X 1 carbon 20BS do not recognize the Mini Display Port

  Hello - I have recently acquired a Thinkpad X 1 carbon 20BS with a new installation of window 10. While I am able to connect to external monitors via HDMI, I was unable to do that via the Mini Display Port. Connection of a monitor to the Mini Display Port didn't do nothing - the monitor is not identified by Windows.

  So far, I have installed the drivers of:, but it did not help. Any help to find ways get the carbon X 1 to recognize the Mini Display Port will be really appreciated.

  Thank you in advance.

  Jake - Thanks a lot for the reply. Happy to report that I was able to get the mini DP to work and he recognizes the compatible monitors very well.

  I tried to find a solution to link the Thunderbolt display carbon, but unfortuantely it seems not to be a Thunderbolt controller that is compatible with the mini DP carbon.

• EliteBook 8440p: supports the elitebook 8440p

  OK so we (my father and me & anyone else) are repairing an Elitebook 8440p for my father and I wonder even if the elitebook 8440p does not support windows 10 - it does support windows 8/8.1?

  I ask only because my father gave me 2 licenses and I was wondering if the elitebook 8440p support windows 8/8.1 cause then I can give 1 license while my lenovo has another

  -cause the way that I see - if it does not support windows 10 then at least it would support windows 8 or 8.1 lowest

  so the question - it's officially support or is there a list of the devices supported for windows 8/8.1?

  Hello:

  All I can tell you is that there is no official support from the W10 by HP drivers for the 8440p.

  I have the model that preceded the 8440p (the 6930p) and it works fine W10.

  Mine doesn't have a webcam, and I do not like the fingerprint reader security features, so I can't report on these devices.

  All the drivers are installed but in Device Manager, and I used the drivers for W7 for everything what has not installed W10, such as the card reader and HP 3D driveguard.

• EliteBook 8470w display (2 external + 1 internal) Configuration

  Hello everyone!

  I use a 8470w with Windows 8 Pro EliteBook and the latest drivers on the HP site. I do not use any docking station, but an over-pants AMD graphics card.

  I know that the laptop can support up to five screens, when you use a docking station. But I want to just use a monitor to the VGA port, a screen on the DP and the display internal for laptop.

  When I try to set up a desktop extended across all three screens (everyone gets recognized by the laptop), Windows tells me that it is an invalid configuration. I have to turn off an external display to use the construction in the screen.

  How can I use the screen of laptop computers and two external screens on VGA and DP together?

  And what kind of Port, Docking-Station/displays are generally supported by the EliteBook 8470w?

  Thanks for your help!

  Hello again!

  I solved the problem by myself and it's a very simple solution.

  I just had to use an active DP-DVI adapter online. It has something to do with not enough sources of clock in the AMD Chip.

  Maybe someone can say that the HP hotline.
