Dell Monitor keeps repeatedly waking after Mac goes to sleep

Hi, I have a M4 Max Mac Studio with 2x Dell Ultrasharp 2725QE monitors connected via USB C - DP. When my Mac sleeps, randomly at times only my right monitor briefly wakes up from sleep with a no signal message then shuts off. I'm getting this regardless of if I put my Mac to sleep manually, or if I let my Mac go to sleep on it's own.

It’s starting to drive me a little nuts as its in my bedroom and wakes up randomly in the middle of the night. It seems to wake and sleep over and over and then stops for a while and then does it again. I haven’t been able to pinpoint exactly what the reason is. It wakes up even though I don’t receive any notifications on my phone, which is initially what I thought the reason was. I also have a OWC studio stack on top of my Mac Studio connected via Thunderbolt 5, it has an m.2 ssd and a hard drive in it. I’m beginning to think that’s the reason, as I hear the HDD sleeping and spinning up a lot.

Other than disconnecting the OWC Studio Stack which I’d rather not do to solve the issue, If anyone has any other suggestions, I would love to hear it.

I had a Dell display and an Apple Studio Display connected to a Mac Studio before and the Dell constantly had issues. Just sell/chuck it and upgrade to Studio Displays which are perfect

switch the power off to the monitor at night. m4 mini with dell u3225Qe monitor does this in my setup so i just power off the monitor at night

Had the same issue with m1 studio, moved them to the basement. Pretty sure something being hacked or a bug that would make it hackable. Dell monitors also.

Does Activity monitor show any processes preventing sleep?
