I have a dumb tv (which has HDMI ports but no USB port) hooked up as a second monitor with my computer.
I want to screen mirror my android phone OR play videos off a USB stick
BUT ALSO allow a second person to independently use the computer and the computer's own monitor.
Currently my dumb TV (which again is a HDMI-connected second monitor in another room) plays files off the computer's hard drive, but another person cannot use the computers hard drive to play video games.
Thanks!
