Mouse problems with display port 1.2 in MST (4K display)

I haven't seen the issue since before High Sierra 17A405 and 378.10.10.10.15.117 (web drivers). I'm using High Sierra 17A405 and 378.10.10.10.15.120 (web drivers) now.

Hi all,

I got Apple's request to confirm the Bug has been solved in High Sierra, I have tested today and so far it is working fine for me. Before confirming it is solved, I would like to get your feedback with this OS version.

The problem persists in High Sierra. It doesn't happen until you put the computer to sleep. Going back to El Capitan 😟

I just hooked up a new 4k TV to my MacBook Pro to come up with a problem with my mouse being sluggish.

I never dreamed that the problem might be the display, but I discovered that with this Samsung 4k 40" TV that you have to enable Game Mode in the settings, and my sluggish mouse problem is gone.

@genamariaelena Not resolved in High Sierra. Even latest 10.13.1 Public Beta still experiences that problem. Only work around as in my previous post works for me so far. But once you restart with the notebook closed the problem re-appears.

Problem still occurs in High Sierra occasionally

Using High Sierra Public Beta 8 (17A360a), MacBook Pro 15" Retina Late 2013 with Dell UP2414Q. It got better and occurs less but still somehow comes back randomly.

Also went through the usual steps (clear PR ram etc.) but unfortunately still doesn't seem completely fixed.

Just installed final official High Sierra - still has the problem occasionally as well.

Also on a side note Nvidia has not updated the Cuda and/or Web-Driver so far for High Sierra. Not sure if that would eventually improve this issue or not. Will report back once there is an official driver from Nvidia.

Very unfortunate to keep suffering this problem making an expected set of professional tools impossible to be used: Macbook Pro + 4K professional display + Mac OS

I have opened a bug report to apple, I encourage all of you to make it visible through further bug reports and direct feedback, assuming Apple support does not read support communities:

Any one testing latest Beta version from next Sierra patch?

After weeks of trial and error, it seems that I've found a workaround that has been consistent (Macbook Pro on Henge Docks, docked in clam-shell mode, Dell 5K display, Apple Bluetooth mouse):
1) Select "Prevent computer from sleeping automatically when the display is off" in Energy Saver settings in System Preferences)
2) Create a hot-corner for "Put display to sleep" (option in "Desktop & Screen Saver" in System Preferences).
3) Make the screen sleep by moving the mouse pointer to the hot-corner

4) Wake the screen up BY PRESSING THE MOUSE.

Remarks:

- If you use the keyboard to wake the screen up, the problem persists.

- If the screen goes to sleep by itself (timer), the problem is still there when it's woken up - no matter what method.

I hope it works for at least some more people out there and that it could give Apple some hints on how to fix it.

Does this workaround last until next sleep/power cycle? I used screensaver triggered by hot corner for a while (there may also be a way to enter screensaver with a shortcut) solution but given up as it is not reliable. Both color profiles trick and screensaver always fix the issue only to reappear short after. Mainly on the following app (or even tab within the same app) switch. Ended up disabling MST until there is a fix or I find couple of days to revert back to el cap. In my book 30fps slideshow is still better than inaccurate pointer which is a disaster in graphics apps.

It's been working fairly reliably. But only in the precise conditions stated (see remarks). And, as putting the screen to sleep (going to the hot corner) and then waking it up (mouse-click and logon) only takes a few seconds, it's not such a pain (well, Apple, you still need to fix it!).

This unfortunatly does not work for me. When waking up, the problem is back.

(MBP 15" Late 2013 with 4K DELL up3214q)

For me only changing the colour profile works each time until the next wake from sleep.

It's always on when connected to the power supply (you can also only use it docked in clam-shell mode when it's on power anyway). Only the screen is turned off, both on timer (set on "Turn display off after..." in Energy Saver settings) or by forcing it off via hot-corner.

I have the exact same model MBP and Monitor and I have the same symptoms, it's been a while since I checked this thread and yeah changing color profiles seems to be the only thing that fixes it for me too.

I had this problem in Sierra and just rolled back to El Cap. But first I reached out to Apple about it. After having me do some troubleshooting (most of which was already covered on this thread) they basically told me to contact Dell. I don't think you're going to get a fix until they actually recognize that it's a bug on their OS.
