They should replace music videos with holograms.

Back in 2020, Sony unveiled a 15.6-inch display that used eye tracking and a micro-optical lens to deliver 3D visuals without the need for glasses or VR headsets. Now a 27-inch, 4K model has joined the Spatial Reality Display lineup.
The new display works pretty much as before, where the LCD display panel has a micro-optical lens above it to divide the onscreen visuals between a viewer's left and right eyes, while a new generation of vision sensors promises improved facial recognition and tracking. The system can dynamically adapt the image as a user moves around – up to 25 degrees left and right, 20 degrees up and 40 degrees down.
The 3,840 x 2,160-pixel, anti-reflection display sits at a 45-degree angle (though Sony does note that the "actual effective stereoscopic resolution is less than 4K"), has a response time of 14 milliseconds, and manages 400 nits of brightness, 1,000:1 contrast and a color temperature of 6500-K.
Proto, a holographic communications startup based in California, has built a system capable of beaming just about anything from one location to another. Okay, maybe not literally—this isn’t Mike Teavee’s unfortunate turn of events at Willy Wonka’s chocolate factory—but visually. If its image can be captured in front of a white backdrop, Proto can teleport it from one location to another, successfully performing what’s now commonly called “holoportation.”
Sometimes seeing a person in 2D simply isn’t enough. To give the telecommunication experience a little extra oomph, organizations from Google and NASA to smaller startups are hard at work developing what they call “holoportation” devices. These devices capture a person’s likeness and cast a hologram of them to another location to create a teleportation effect, hence the amalgamated term.
