My guess would be the power supply is putting out something closer to a square wave than a sine wave and the monitor power supply is unable to turn that into DC.

They market it as a pure sine power supply: https://eu.ecoflow.com/products/river-portable-power-station...

Is there another appliance that I can test to see if that's the issue? I don't have an oscilloscope.

Edit: I just tested powering it from a UPS: It's flickering more now and when it show the correct content it stays for a second more then when powering from the ecoflow.

The monitor model is: BenQ GW2780-T.

I would think the same for some products but AFAIK those Ecoflow batteries are quite fancy.

I printed a document using one and generally printers hate running off generator power.

Laser printers don't like them. It's because the fuser is high amperage. Nothing to do with power quality.
