MacOS Sierra not recognizing external displays and going black

Did Apple provide any solution to this? I'm experiencing it with my new Asus VG245H monitor. I'm hooking the mini display port/hdmi adapter to the MacBook. Then I plug an HDMI cord into the adapter and run it to the monitor. The monitor will show blue screen with "no signal", then it looks like it goes to sleep. My MacBook recognizes the monitor and I'm able to adjust the "arrangement" in system references. It also seems like I'm able to drag programs to the monitor because the programs fade when they are halfway off my MacBook display. Weird. I need a solution ASAP.

Just back from apple store. They were able to replicate the problem but they only offered a solution to format my SSD and re-install the OS. I said no since I've already done that....

It seems that there is no solution other than waisting your time trying to fix it.....

We are doomed.

It looks like I might be selling my MacBook and getting a dell/asus/etc. (something that runs Windows 10). It always seems like it's a struggle for stuff to be compatible with mac. I won't give up on my iPhone though.

Ghost_Russia's post seemed fix my issue. And I tried everything.... It's been blue-screening on external monitors at home, glitching and jumping cursor on the 80" Smart screen at work, not working with projectors.. At least at home back to working!

High Sierra 10.13.1

2017 15" MBP

3.1 GHz Intel Core I7

16 GB

Radeon Pro 560 4 BG

Intel HD Graphics 630 1536 MB

Same here I came in today to teach hooked up my laptop the same as every day but it wouldn't connect i tried restarting with the adapter in, with it out but it would not come up in the display preferences. Thanks Apple for screwing over so many without a warning

PLEASE FIX THIS

What changed between then and now? Update of the system? Which one? Which mac.

It may feel good to rant, but without specific information nobody can assist you. We are just users like you.

I also teach and connect my mac to many different projectors, day in and day out. It has never failed, since 1999 (my first laptop, with Mac OS 9) and including the present (2014 rMBP, currently running 10.13.1). VGA projectors, HDMI projectors, TV, they all just work as expected.

I stand corrected. The problem still exists. Super-frustrating! How can any business user who needs to plug into different displays throughout the day put up with this. Apple did not fix this with the .1 release of High Sierra. I must tell you that PCs and non-iPhones are looking better by the day.

I have the same, or at least a similar question. I'm not particularly savvy with computers, so I hope someone will be able to explain what to do if there is a solution. The devices I am trying to use are:

1. MacBook: MacBook Pro (13-inch, 2016, Two Thunderbolt 3 ports)

2. TV: LG 42LB551T-TC (at home)

3. Various projectors with HDMI and VGA cables (for work)

3. Docking Station: Targus DOCK110 http://www.targus.com/uk/usb-multi-display-adapter-black-aca928euz

Regrettably, I installed High Sierra a month or two ago, not realizing it was a beta version and not having backed up my previous version of Sierra. After doing so, I have not been able to use any external displays like my TV and projectors at work. I have been using a Targus DOCK110, and it seems to work well, but it no longer works. I went to their website and couldn't find an update for High Sierra. As my docking station also has a DisplayLink logo on it, it searched for a possible solution with that and found this link: http://www.displaylink.com/downloads/macos. I downloaded and attempted to install the 4.0.0 (19 Sep 2017) software, but when I try to install it, I am prevented from doing so with a message saying something about a more recent version already existing on my drive. Can anyone help me with this?

Thanks in advance!

If have i nearly similar Problem with my Samsung 4 K Monitor.

With Sierra - works perfect. Now 3-7 times per hour it re-syncs the Monitors and the Notebook retina Display and the 4K Display goes dark for a couple of seconds. I also reset NVRAM but this didn't help (as expected).

I'm really annoyed by Apples QA these days.

Environment:

Mac Book Pro Retina late 2013 16GByte Ram, 512 GB SSD Core i7

Samsung U28E850R connected via Displayport

Thanks,

Michael

I checked the Nvidia website for mac drivers for sierra. LOW AND BEHOLD! THEY EXIST!

http://www.nvidia.com/object/macosx-cuda-8.0.46-driver.html

This little driver made my 2012 Mac Pro Retina with 660 GTX actually fly and run way more efficient graphic wise and fixed my external monitor hiccups.

you can update via system prefs.

Didn't feel the need to search for drivers until I installed MAC OS SIERRA.

EVEN THOUGH I LOVE APPLE! GREAT PRODUCTS! SHAME ON APPLE FOR GIMPING THE GRAPHICS DRIVER IN AN ATTEMPT TO FORCE UPGRADE!!

I bought an HDMI cable, going through a HDMI>USC C adapter and it is working fine.

I am glad you got it working.

It also happens to my LG 27 4K monitor which I bought recently. It is the MacOS issue...

Same thing happened to me and I need the extra monitor for work purposes

I have the same problem when I try to connect with my LG 5K monitor with the clamshell closed. It crashes completely....

It only started after updating to high Sierra.

I have MBP late 2016 w/t screen
