I would like to use a HDMI splitter to mirror my desktop (with windows 10 pro) monitor to another monitor. Can anyone who uses my computer detect that I am using a HDMI splitter without looking at the cables behind? How about VGA splitters? Are they detectable? I want to make sure that my second screen will stay hidden for security purposes. This is only for mirroring, not extension of the display.
Thank you.
Thank you.
