U2414H, Mac Book Pro, DisplayPort 1.2 empty, solved

I'm posting here in the hope that it gets indexed by search engines and other people can find the answer that I spent a few hours searching without luck.  At first, I must say that I am generally very pleased with this monitor - like bezel-thin, very good quality picture, easy to set up and a great price. However, most of this post is going to be a complaint and attention to others. told me, incorrectly, that my early 2011 Mac Book Pro 15 "mini-DisplayPort taken in charge the DisplayPort 1.2 Protocol. It turns out only. Then when I activated the DisplayPort 1.2 screen turned white, as the instructions said he could. No biggie, you would think - just get on-screen display (OSD) to the top again and disable DisplayPort 1.2 or do a factory reset. Here, you can't get the OSD until a source is connected correctly to the screen. Which means that you can not disable DisplayPort 1.2 or do a factory reset, you want to do because you cannot successfully connect to the screen, until properly connect a device to the screen. And so on and so forth.

There is no other way to do a factory reset, so the only way for me to reset the monitor that is to go buy a mini-DisplayPort-HDMI cable in order to connect to the monitor in this way and do a factory reset. I confirmed this with a call to Dell technical support, too. I don't quite see how thought happened during the design of the firmware. How do you design a monitor where the only way to do a factory reset is when a device is connected correctly? A major flaw, but it will apply only if you don't know this in advance, where this post.

It also would have been clearer if the warning had said "this can make your blank screen which, until you have another cable to connect via HDMI, means that you have essentially an expensive piece of plastic."

Follow these steps to disable the DP1.2 on the U2414H WITHOUT signal input

Buttons =.
Preset, brightness, Menu, power supply, output

When you press the Menu button, the buttons are then =
Up arrow key or down arrow control OK, return, power

* Turn off the monitor
Unplug all the video inputs of the U2414H wiring
* Turn on the monitor
* Press the Menu key
* Press the button OK check (3rd left) and hold FOR 15 seconds
* Disable DP 1.2

    Just a little confused here.  Thank you! B.

    Yes, the HDMI cable can connect the MBP to your TV for use as a monitor provided your TV takes over that. The MBA in need: output audio and video HDMI using third-party Mini DisplayPort to HDMI (sold separately) on the Apple Store locally or online adapter: Moshi Adapter Mini DisplayPort to HDMI (4 K).

  • Mac Book Pro cracked screen inside, no damage to the outside

    Hello

    I woke up this morning with mac book open and off. I have seen that my screen was quite dirty and decided I have to clean fingerprints on it. I used a Clorox and a paper towel to clean. Once I finished I turned an and saw my screen cracked. When I rubbed my finger on the screen it there's no indication on the front or the back of the screen he was hit there. It is only within the screen. I took it to apple and they said it was an accident, when I washed only the screen, as I did with several Mac Book Pro, I bought in the past. I have Applecare, but he does not apparently. No where else on my mac does show that I have damage and I did a diagnosis, and there is nothing else wrong with my system. They said that I am $ 800 and it's just scandalous due to a stream for the super screen thin on the inside. I don't know where to go from here, but I've used Apple products in my life and being a college student, I don't have that kind of money to fix. This problem should of never happened. I do all my graphics and coding on my Mac and have always loved. I also have a case of black Tech21 surrounding for added protection so something like this has not happened. Please if there is any help I can get here, it would be highly appreciated.

    Benjamin Schmidt

    Make your case to a store manager, but it is difficult to claim "just happened by itself." Be nice to the staff of the store, you are basically arguing for special treatment.

    It does not mean you did anything on purpose, but the MacBook was responsible, if you are responsible for. The cause could be anything from a drop of abrupt changes in temperature. Who knows...

    Good luck!
