The 'Phantom' claims to be world's first transparent computer monitor, touts 5,000 nits of HDR brightness — 24-inch 4K panel from Virtual Instruments launches Q4

The Phantom employs beam-splitting technology similar to what's used in aviation HUDs, or teleprompters, to reflect a screen onto a half-glass, half-mirror surface, giving it that transparent look. It also claims to have adjustable transparency, meaning you can have a completely opaque monitor if you wanted.
