Ventura forgets display settings

I have this problem too. MBP 14" M1 Pro. Connected to Caldigit TS4 dock, using UBS C display-input. After Sleep, the external display is no longer the main display and returns to 30Hz and forgets the scaling settings as well. Very annyoing.

Same problem here, on an external monitor connected via an USB-C hub and DVI. This is so annoying, because it also forgets about the dynamic wallpaper settings, so the desktop keeps being bright even at night time.

Here is the answer from Caldigit Support:

The wake from sleep issues you describe are known on macOS systems and have been noted on versions of macOS since Mojave. The issue has seen a resurgence on the latest versions of macOS and on Apple Silicon architecture in particular. There are a couple of possible mitigating solutions.

If you have twin makes and models of monitors, one of the simplest and most generally reliable is to swap in a monitor that isn’t a twin of the other. We would suggest disabling any power saver or energy saver options on the display.

We’ve found that this can help with displays working consistently through the dock. I would also recommend waking up your computer from sleep with its internal keyboard rather than any external peripherals such as an attached mouse or keyboard, as this sometimes helps the computer wake up both itself and attached displays correctly.

You may wish to turn off sleep mode to circumvent this issue: Official Apple Supportguide/mac-help/set-sleep-and-wake-settings-mchle41a6ccd/mac. Or there is a 3rd party App called Coca that can keep your Mac awake with one click: https://apps.apple.com/us/app/coca/id1000808993?mt=12

Our docks and hubs work using the drivers present in the host operating system rather than any of their own. Considering the issue only occurred after you updated your operating system, it may indicate a hiccup with the Thunderbolt drivers on your computer as they updated.

Please let me know if you have any additional questions or concerns.

Of course, this is a bad answer. Basically they say it's Apple Fault and they have not identified the bug and have no idea how to solve it. None of the tricks worked for me. And changing one of my monitor for a not-twin-one? lol? What a mistake to spend 450€ in a dock...

I have the exact same issue with MBP 14" M1 Pro + Caldigit TS4 + 2 monitors in USB-C (clamshell mode).

Worked without issue with MacOS 12 and the Caldigit TS4.

Not sure however if the problem comes from Ventura only, or the combo Ventura + Caldigit TS4.

Until now, I still don't understand why the settings are reset sometimes, and sometimes nothing happens.

Note: the issue is not listed on the CallDigit page: https://www.caldigit.com/category/ts4/

Note : I did not try to update the firmware yet, as it requires a Windows computer... sigh.

Any help will be appreciated.

I have found a solution for me, that might not work for everyone: When I use displayport, it no longer forgets the settings. Sure you need a display that supports it, maybe it also works with displayport to HDMI-cables.

I'm on 13.0.1 as well, but the problem persists.

I had the problem with a TS3+. Recently switched to a Razer TB4 hub - same problem. It's got much worse with Ventura.
