Ok, I'm sure this is going to sound really silly, but while streaming from my PC to my docked steam deck last night, I dropped the keyboard on the carpet and the brightness of my stream suddenly went up way too much. I have no idea what combination of keys could do this but I've been trying to find what to do to bring it back to normal. I tried rebooting sunshine, the PC, the steam deck, nothing. It's way too bright.

Any idea what could've happened and how I can resolve this ?

Thank you so much for any help!
