My monitor connected to the UPS blinks when I switch on/off home lights!

Hi, my usb-c self powered monitor, that is connected to a APC Back-UPS 950VA, 230V, AVR with the laptop (https://www.se.com/es/es/product/BX950MI-GR/apc-backups-950va-230v-avr-tomas-schuko/) go off for a couple of seconds when I switch on/off lights or other devices in my house. Only happens if monitor is connected to the APC UPS and not if plugged directly on wall. I bought this to protect the monitor and laptop and now I don't know if it's worse.

Show me how this is connected to the UPS. Show me a short video of this problem happening with a link to view.

Sounds more like you have an electrical wiring problem in your home / building.
