im looking for a way to mirror monitors display. not making my monitor appear on nother device, i mean flipping it about the y axis, like im looking in a mirror. the invida control panel and win10 display settings dont have this option, unless i missed it. the best i found i a program called ultramon, but it has a 30 day trial period and might require 2 displays. thanks in advance.
