Hello,

I would like to develop an VJING app with HDMI detection for dual-screen functionality : one screen serves as a control interface to manipulate content displayed on the second screen. I tried several manipulations but did not suceed to detect HDMI and use it.
The idea is to put a single full screen div from the html on the second screen to project it as a live video. Is it possible or too much ?

Thank you for your response !

Yes of course, I just saw the device documentation electron but nothing about HDMI,
ask me what its not clearly explain

I send you a quick video of a similar app where it’s possible to choose an output video from the options : https://youtube.com/clip/UgkxZh4xpZGJR7SNsFjx14nxB3gN4dvKrkW4?si=xV_-OwlluwRS9EQF
