Extremely shitty viewing angle.

Yes, it will also have 1/1000 the brightness of a regular 4K screen.

That's basically projectors.

People actually did this some time ago. But it's gonna be blurry.

why is the user so disgusting?

It's accurate.

>a giant magnifying glass somehow magically makes a 4k picture hover in midair

Yes, you can probably still buy fresnel lens kits on ebay.
This shit was the ghetto projector rage like 15 years ago.

You can actually buy that, designed to be used with a smartphone for the screen.
I gave one as a (joke) birthday present once.
Never heard how terrible it was but I'm sure it's utter shit.

Brightness is determined by the amount of photons entering your eyes per second. If you had a tiny 4k screen that was magnified, either the 4k screen would produce the same amount of photons, making the energy savings useless, or it would produce less photons and the brightness would be darker, since you're just spacing the photons out more.

Also, the tiny screen would generate large amount of heat and would require extra cooling, reducing its efficiency.

"screen [arrow towards screen]"
are you more retarded than OP?

If you could
a. fix the loss of brightness from mangification
and b. fit the same resolution into the screen 1/1000th the size without it costing more than just using a regular sized screen

Actually OP, now that I think about it, it would be far less expensive and efficient to produce a giant screen with large pixels, then use a magnifying lens to reduce its size.

I lol'd

The image would but upside-down.
Easy to fix by turning the source image upside-down, but the drawing is wrong.

Magnifying glass doesn't flip shit, does it?

OP's image is more like a view camera.
It projects the image on a secondary screen.

Yes projectors work

Apparently no one on Jow Forums knows how a rear projection TV works.

LOWRY

This is 7th grade physics
next

Except it does... Did you skip middle school physics, summerfag?

Only once you're past the focal point the image becomes inverted.

It sort of does

they actually already make those, they're rear projection tv's, the method of projecting the image is different though, instead of using a small tv, they used an actual projecting lens

that's exactly how those massive old rear-projection TVs worked, only with a tiny little CRT instead of an LCD panel
they produced a slightly fuzzy image, but overall they were pretty comfy, just insanely big and impossible to get in/out of rooms with small doorways
I remember helping my cousin move into his new house, the old occupant left one in the den because they couldn't be bothered getting it out
we had to take it apart to remove it from the room, so I can only assume it was brought in and assembled there in the first place

ITT: what it VR

Congratulations, you just invented a projector.

if you double the brightness you double the power draw, idiot. if you want it as bright as a 44" 4k tv itll have the same power draw, its just physics at this point
