Hello,

I have a MacBook Air M2 and connected my Samsung LC49RG94SSRXZG as an external monitor via an Anker 565 USB-C hub and via DisplayPort. macOS 13 only recognized the full 5120x1440 resolution monitor after I disabled FreeSync in the monitor menu and lowered the refresh rate from 120Hz to 100Hz. Side question: Is macOS incompatible with FreeSync, or why do you have to disable it on the screen? Otherwise, macOS displays the resolution 5120 x 1440, but with the addition "low resolution".

My real question is regarding the color profile. Here the colors are unfortunately very pale with the suggested colour profile named like the monitor model C49RG9x and unfortunately not perfect with the "General RGB profile". Unfortunately, I can't do it any better with my own profile. Does anyone have any tips on how best to set the colors for macOS on this monitor model? Or is there a good profile for my model available to download?
 
I bought an Anker 577 Dock and it's working in 5120 x 1440 now without problems.

I see, even with 120Hz?
Do you also have the issue that when the Macbook wake up on it's own that the monitor will wake up and is "black" for few seconds and then goes asleep again?
 
Only working with max. 100 Hz.
I don't have the problem with sleep mode.
 
I'm just using a USB-C to Displayport cable and I also got the colors working at 100 Hz but that wakeup issue is pretty annoying. Which cable have you used to connect the monitor to the dock?
 
I used the original DP cable from Samsung which came with the monitor.
 
I thought the dock has only usb c ports and no DisplayPort connectors?

I tried now a USB-C, but then sometimes after the MacBook wakes the screen goes immediately black again and I have to reconnect the dock. Have you noticed that behavior too sometimes? Also my Apple Watch always says it unlocked my MacBook twice.
 
I see, thanks. You never had the behavior that the monitor went black again after waking up? So your setup is working perfectly?
 
Try to reset the Monitor and unplug it for 30 minutes completely.
Also look for FW update.
