Thunderbolt Display flickering

Hi There,

Apologies for writing in this forum since no other forums exist for Thunderbolt displays. Please transfer to appropriate forums if any.

I have a Apple Thunderbolt Display 27inch (2560*1440) Radeon Pro 560X 4 GB graphics. It is connected to a MacBook Pro late 2019 model through a Thunderbolt 2.0 to 3.0 bridge.

At times there is a lot of flickering that happens and sometimes it is none or very less. Any suggestions to rectify this or why this happens?

Thanks in advance to Tom & Lui.

iMac screen flickers I have an iMac (retina 5K 27inch late 2015) that runs macOS Mojave 10.14.6. My graphic card is AMD Radeon R9 M390 2GB. In the last few months after using the iMac for a few hours or sometimes 30 min after restart the iMac screen starts to flicker and the only way to stop this is to shutdown or restart the iMac. In time I've noticed that the speed of flickering is increasing in its getting harder and harder to close the apps before restarting the iMac. Is anyone else experiencing the same problem?

MacBook Pro M2 Max external display flickering I just got a MacBook Pro with an Apple M2 Max chip running macOS 13.2.1 (22D68). Sometimes, depending on the content of the screen (a given webpage, PowerPoint welcome screen), the external monitor shows some vertical grey lines, either statically or flashing (see the latter on the following video). https://youtu.be/oeY1EGmOP7U It's hard for me to be able to consistently reproduce this bug. Furthermore, if I change the display profile, the flickering goes away only to come back when different content is shown on the screen. The external monitor specs are: LG HDR 4K: Resolution: 3840x2160 (2160p/4K UHD 1 - Ultra High Definition) UI Looks like: 3840 x 2160 @ 60.00Hz The device is connected with an HDMI cable directly pugged in the laptop port.

Pixel Flickering My new Mac updated to a new software 12.3 today and since morning I have been seeing pixel flickering on the top right small rectangle during every motion or graphic change. I tried removing my extended display and after that it is acting normal. I don't know if it with the display adapter to extend type C - hdmi or new software. What do you think is happening? Here's a screenshot that I was luckily able to capture it:
