DeskMirror does the improbable, the implausible, the impossible, the imponderable. And it does it impeccably and impressively. But what exactly does it do? DeskMirror reflects, reverses, flips, inverts, mirrors half of your display onto the other half. It does not rotate. It does not duplicate. It mirrors like a real mirror.
Yes, there is a way to mirror the whole screen. You need two screens. Half of two screens is one whole screen.
DeskMirror requires source and destination rectangles of display real estate. The two rectangles do not overlap. With only a single screen, the source and the destination each claim half of the screen. With two screens of equal resolution, the source and the destination can each fill one whole screen.
There's a trick known by those who know. A single monitor with two inputs can simulate two screens as if there were really two physical monitors. One input is normal, and the other input is a mirror image.
I like your program DeskMirror very much. I am an artist, and I use it for having a 'mirrored' look at my work in progress, in order to judge the form and composition (as recommended by Leonardo da Vinci).
I wanna thank God for this free product. Thank God, and thanks to the creators of DeskMirror. Thank you so much. I'd been struggling to look for this app. Nvidia drivers, control panel, and Intel drivers don't have this feature. Very useful app!
