Fascinating. By default, though, this seems like it would just result in low contrast and difficulty reading, unless turned to opaque mode.

The thing I'd love to see, which to the best of my knowledge isn't possible with normal HDMI/DP/etc, is an opaque monitor that allows rendering an alpha channel as actual transparency. That would allow things like setting your desktop background to transparent, so that when you have one non-fullscreen window, the rest of the screen is transparent.

Are there any display technologies or protocols for sending RGBA to a monitor, and letting the monitor handle the alpha?
