I have an external 4K monitor that is connected via an legato dock to a MAC 2017 4 port USB-C laptop. When I initially connect the cord from the dock to the MAC Catalina sets the brightness of the Retina display to max even though the setting if for automatically adjust. Each time I connect I need to go in and manually change the brightness setting. This issue did not happen with Mojave or High Sierra.
MacBook Pro 13", macOS 10.15
I upgraded to 10.15.3 a few days ago, and so far, it seems to have helped my situation (knock on wood). My external monitor has retained the brightness setting after numerous sleep/wake cycles. Prior to the OS upgrade, I would have had to manually adjust the brightness at least a few times. I'm really hoping this fixed it for good, but only time will tell. I'm cautiously optimistic at this point...
Same, I haven't had the screen saturation issue since updating to 10.15.3. I've read that the graphic drivers have been updated: AMD support, to version 3.5.5, and Apple Intel support, to version 14.4.23
Fingers crossed!

I can confirm the same thing happens to me as well with my LG UltraFine 27" 5k display. Was expecting that an expensive monitor like this, purpose built for Apple wouldn't have any issues, but it does. Really frustrating to constantly have to re-adjust the brightness every time I wake my laptop up from sleep mode. I also have issues with my second external monitor (a BenQ SW271 4k display) where it won't come on after waking up from sleep unless I turn it back on first and wake it up or plug it into a different USB-C port on my laptop, or restart the computer. Very annoying.
Same issue here but without external monitor.
MacBook Pro (16-inch, 2019), 2,6 GHz 6-Core Intel Core i7, AMD Radeon Pro 5300M 4 GB.
10.15.2 & 10.15.3 - no difference.
Happens randomly after opening the lid from sleep. No external monitor.
Going to sleep & wake-up again - issue is gone.
Changing a color profile and going back to default one - issue also gone.
I have the exact same issue that the screen wakes up and is overly saturated and dark. I mostly experienced this when an external monitor is connected (via usb-c to display port cable) and have actually also seen it on the external display. So it seems like it really is related to color profiles and not a hardware issue (at least not an issue with the mbp display directly).
Hey Brad, in our office we have a number of people having the same issue. We connect multiple displays through a usb-C dock (PLUGABLE TBT3-UDV) and when connecting the cord, or waking the laptop from sleep, the brightness goes to max since Catalina. It's frustrating having to adjust the brightness every time. Apple, is this on your radar and scheduled to be fixed?
Great to hear it's not just me. It seams every release fixes some things but yet breaks even more things for external displays. There simply is no consistency. Next release that works will be the last upgrade my MAC sees before it's retired from service. No more updates for fear of something else will be broken.
Thanks again.
Well had an absolute awful time upgrading to 10.15.2. Took 3 times with each rolling back to a working .1 to try again. Seems that during the upgrade process the WindowServer process dies and stops everything from progressing.
I can confirm this problem still exists in 10.15.2.
Time to roll back to avoid any other 10.15.2 issues i could inherit that I don't want. Wasted 3.5 hrs the way it is to get an actual upgrade to work....
Well 10.15.2 kernel dumped twice overnight. Thats it rolling back to 10.15.1 as at least it did not exhibit this behaviour. Quality of these updates is getting worse in each release. Really is time to find a stable release and stick to it.
Yes since 10.14.6 appears that your not expected to use a MAC with any external monitor. It just does not function consistently. As holidays approach I'm considering High Sierra to return to a usable setup. I know its old but the other option was 10.14.5 but there is no way to get back to there ;(
I can add my description of the issue on my 16 inch MBP. When my screen wake up from sleep the display looks overly saturated and dark. It’s as if when it returns from sleep, the color profiles are messed up.
I have not hooked it up to any external monitors, I get this problem when the 16 inch turns off the screen after the 15 minutes as set in the energy settings. If I turn off the screen using the active corners it goes on as it’s supposed to when I wake it up. Also, when I encounter the problem I can move into the active corner - turn the screen off and then turn it on - and everything is ok again.
I hope it a software issue that can be solved either in the MBP or in Catalina. I hope I don’t have a faulty MBP....
I'm seeing a similar problem on my new MacBook Pro 16, in that most times my laptop comes out of sleep the colour's all washed out, and I need to dim & brighten the display, or sometimes I have to go into the colour profiles and toggle the profile used back & forth. It's getting somewhat frustrating!
I'm having the same issue with the screen being overly saturated after waking from sleep. Tried resetting PRAM, SMC ... Apple suggested I take to Apple store to have the hardware checked. Will report back.
Thanks @boomspot, @druf. Seems maybe Apple have fixed one of the 4 external monitor issues. As the OS is still getting external monitor resolutions incorrect when it wakes from sleep I guess I'm sitting on 10.15.1 until a later release. Good to know that 1 out of 4 was fixed in this update. At this rate by .6 external monitor support may be working like it was in High Sierra and early Mojave (not 10.14.6). Thanks all.
