Describe the issue

Hi,
I have been using this amazing tool from the last 6 months with my Dell monitor.

Recently, moved to a new place and changed the monitor to a HP one, but the brightness controls are not working for my HP 24-inch monitor (Monitor Details - link)

Can you help with this ?

Mac Version: Sonoma 14.5

Expected behavior

Monitor controls should work from the navbar and change the brightness of the monitor.

Anything else?

No response

The display or the dongle used might not support DDC control (note: you are using an outdated app version but this should not cause an issue I think).
