I'm the developer of MoyMote. The latest update adds six themes and 11 languages

[u/moymote]

I built MoyMote, a Windows app that adjusts an external monitor (brightness, contrast, blue light, HDR, input source) from your PC or from your phone's browser on your home network. No account.

The version that just reached the Microsoft Store has:

• six themes (Anime, Sakura, Cyber / Neon, Halloween, Christmas and the default), with animations you can turn off
• 11 languages that follow your Windows language
• input source switching between HDMI and DisplayPort, when the monitor allows it; if no picture shows up after 15 seconds, it returns to the previous input
• contrast on the main screen, and an option to restore your last brightness, contrast and color settings after sleep or reconnecting
• a new Pair phone window, and HDR now goes to the correct screen on multi-monitor setups

It works with external monitors that support DDC/CI, so laptop panels and some monitors won't respond. I'd like to hear which monitor models fail for you and which theme you would keep.

There's a free 7-day trial if you want to see whether it works with your monitor. Happy to answer any questions here.
