There seems to be a growing number of “4K” home theatre projectors appearing on the market, although, many of these projectors - that are also using a 4K logo, aren’t actually 4K. It seems that to produce a 4K projector, it doesn’t need to have a native 4K resolution. Some accept a 4K signal, downscale it to 1080p or something a little higher, then uses something called “pixel shift”, to send two sub 4K images but slightly offset to each other, “effectively” producing 4K. Others upsample after downsampling. There’s a few different ways to do it, but the likes of Epson, Optoma, JVC etc all use this type of approach, rather than producing a genuine, pixel for pixel 4K image.
My point here is that as a retailer, I’m going to be as open as possible about what a projector actually does, and let you know what you’re getting for your money. If it’s not native 4K, I won’t be calling it a 4K projector. Many retailers seem to continue the hazy descriptions set out by manufacturer’s marketing departments, in order to make you think you’re getting 4K. Currently, there’s very little under £5,000 that is native 4K (4096 x 2160 pixels).
caveat emptor

refuse to pay £5k and don’t feel anyone should pay for a projector that isn’t current technology proof!
