For some people, a TV can never be good enough. They want a giant screen that would cost the same amount as a small house if a TV panel was involved, so their only option is to go for some sort of projector. Projectors are pricey as well, but they do offer a much larger image for a relatively reasonable price. Unless, of course, you're looking at the top of the range projectors. Sony's flagship is way more than you can probably afford.
The VPL-VW870ES offers true 4K resolution (not UHD) at 60FPS, laser projection, HDR, 2,200 lumens of brightness, an 18-piece All Range Crisp Focus (ARC-F) lens that offers more precise imaging at the end edge of the picture, plus Sony's '4K Motionflow' which helps reduce blurring on fast moving scenes. It's also going to cost €25,000 (UK price TBA), which is more than some cars.
The point of this projector, I'm told, is for the person who wants the best of the best. They can't abide by having an inferior image, and have to have the very best projector available on the market. Presumably they'll also have to have very deep pockets, or the willingness to put their home up as collateral so they can get a loan. Sony has mentioned sports and gaming as key ways of how people will want to use the VPL-VW870ES, given the recent slate of 4K sports tournaments like the World Cup and games consoles like the PS4 Pro and Xbox One X. The latter is also one of the reasons why Sony added 18Gbps bandwidth and 10bit input processing, which it claims will help reduce input lag and offer faster response speed.
But yeah €25,000 is a lot of cash. More than you can afford, I'll bet. Luckily Sony has more affordable options in the form of the VPL-VW570ES and VPL-VW270ES projectors. Both offer True 4K resolution, but compromise on other features like brightness, lens type, and other fancy things. Still when I say they're more affordable, I'm speaking in relative terms. These two cost €5,000 and €4,000 respectively, which is still out of the price range of most people.
If you really like the sound of these things, however, you know you have something to save up for.
