New M1 MacBook Pro will not save display settings

I have a new M1 MacBook Pro and a Samsung 4K display. about half the time I use it and wake it from sleep, it resets my display settings to the lowest possible quality resolution causing me to have to go back into the settings. I normally only use the Samsung display but if I use both the display and the MacBook display, the laptop screen will default to a very low resolution.

I have it all connected through a DisplayPort cable and hub. I had a 2017 MacBook Pro before this and never ran into this issue.

Everywhere I look up seems to show resetting PRAM but there isn't a way to do this. I also have it updated to the latest version of Big Sur.

MacBook Pro 13″, OS X 10.11

Is there a solution to the issue of screen setting changes not be retained? I just switched to a new MacBook Pro M1 and experience the issue everyday, sometimes multiple times per day.

Apple needs to fix this ASAP.

Thanks for the reply. Unfortunately, I have tried all of this, and it's still happening. I wake it from sleep and the laptop does not detect the display. I've had to unplug and re-plug the display to get it to be detected.

What makes it even worse is it's intermittent. It seems to be happening more frequently though.

I use a DisplayPort cable into a CalDigit TS3+ and then single thunderbolt 3 cable into the computer. I have had this set up for a few days now and before I had a DisplayPort to USB C and still experienced these issues.

Did you ever find a solution?

I just switched from an iMac and older MacBook Pro to the M1 and this issue is driving me a bit crazy. It will not only forget the resolution of both my external display and my laptop, but also the arrangement moving my laptop screen to the wrong side of my external display randomly.

I've been looking for solutions and haven't found any.

Thanks,
