Monterey 12.3.1 External Monitor/Display Issue - No Longer Outputting Signal

I take that back. I've seen the flickering occur twice now on macOS 13.1, but both screens finally kicked on both times. Ugh. Still an unacceptable issue!

macOS 13.1 may have fixed the problem. At least, I haven't encountered it once since installing this update. Has anyone else had this bug rear its ugly head with 13.1?

Has anyone received any helpful advice from support regarding this problem so far?

The last advisor (second level, not the "regular" phone support people) I talked to had me try a lot of things, including a factory reset, but none of it helped. He also filled out some form with me and sent it to the "engineers", later he called to tell me that he'd received a reply from them but I haven't heard from him since then (more than a month ago by now) and I also can't seem to get in contact with him anymore because the supportmessaging link I got just shows some error and the e-mails I send to "acsupportcase" directly go unanswered too.

Correct - the fact that this issue is still unsolved is a joke. My crappy old windows laptop has no problem using my displays / waking them from sleep, but my $2.5k MBP requires me to physically unplug and re-connect the TB3 cable every time I want to use the screens?

macOS 13 Ventura did NOT fix the problem. Way to go, Apple. Do you even care about us anymore? You know, the people who pay *WAY* more than top dollar for your sexy products that are supposed to "just work."

Perhaps for those who might not have found newer drivers

or other links online, with workable solutions for your kit; a

repeat from a few users contributions here. And links from

more recent updates, could help some. (DisplayLink driver

access is related to OWC product, in this presentation.)

There is a partial hardware fix. Plus: links within, to driver

& software (display link, from recent month) to consider.

And the OWC mac-centric supplier of renown again shows

a path could exist with their 'Display' link adapter and driver.

Hopeful this may help some, who keep trying whatever they found. Either

had one, that only worked in one specific time; or didn't get that fix at all.

.& hope this 'quiets' some emails from non-unsubscribable ASC threads.

Still the same issue under macOS 13.0.1 :(

Same problem with me , I’ve tried with two different cables still not working

Still not working after upgrading to Ventura.

What an absolutely ridiculous bug.

Edit: Changing the monitor's color profile kind of fixed the issue. I stand corrected: what an absolute idiot I am.

why was it retitled by monitor?

Upgraded my MB Air M1 to Ventura yesterday. DisplayPort had severe flicker and ghost picture on the LG, TB display was dead.

Networking (EthernetApple Filesharing) also had issues.

Reboot and so on, did not help. Switching to DP 1.2 did not work, black screen.

This morning, plugged all back in, all was back again and TB display works again. So same issue as with previous OS, its not really stable.

This issue is fixed in Ventura 13.0.0. Mbp m1p

i have the same problem with samsung m7 monitor , can't connect it any more with usb type c cable , i even bought new usb cable from apple, i thought my old cable is broken so now i spent 75 euros for a software issue :( .. only with hdmi which is only 30 fps .. it is really annoying as i do mush videos editing and the programs are quite slow...

hope they come with a new update yo fix this bug

For the record I am using the DP on my asus monitor and a usb-c to DP adapter to link it to my Mac, but this “fix” also works with my hdmi to usb-c or just a standard hdmi cable

Hey everyone, this issue has been plaguing me as well for months, I was on 12.0.1 until like June and decided “I never upgrade what could they possibly break?”

I didn’t see this mentioned, but I found that the “most convenient” fix doesn’t require unplugged and plugging in cables at all. Simply go to the display settings, and change your resolution. For me my 1080p Asus monitor I drop down to 720p, the screen turns on and then just click back to the resolution you want and it should work in that resolution. If you let the display fall asleep though you will need to do this again.
