There are 4K projectors, and then there are 4K Projectors – to paraphrase James Bond in Casino Royale. 

Sony's VPL-VW285ES is the first projector that offers true 4K resolution under $5000.

That is, some projectors have true 4K resolution while others can accept 4K content, and use techniques to get improved results out of lower resolution projectors

This section’s list of projectors includes both types, that is projectors with true 4K panels/chips therefore have either 4096×2160 or 3840×2160 resolution without any of that “pixel shifting”, and those accepting 4K content that are 1080p projectors, or 4K UHD projectors (which aren’t true 4K as I keep saying)  Both put content on the screen that is higher resolution than 2K or 1080p.  That means we are including projectors using pixel shifting, such as currently shipping JVC home theater projectors and Epson home theater, and business projectors.  And including the new class of projectors using the “above 2K” DLP chip, like those from Optoma and BenQ, referred to as 4K UHD – 2716x1528x2 resolution, but those use a 4.3 megapixel chip with pixel shifting, that meets the 4K UHD standard.

True 4K is at least 8.3 megapixels with no pixel overlapping.  These higher res 4K UHD chips are 4.15 megapixels but fire twice with the pixel shifting to deliver 8 megapixels. The newer lower res ones are 1920×1080 x 4 – Same native resolution as a 1080p projector but they pixel shift to hit the screen a total of 4 times to achieve the same 8.15 megapixels despite the much larger pixels. We reviewers would have been a lot happier, and consumers less confused if they weren’t called 4K UHD, but merely UHD projectors, as it’s definitely a bit misleading.  By comparison, pixel shifting 1080p projectors like the JVCs and Epsons only deliver 4.15 megapixels of data not 8.3, when pixel shifting, so they are 1920x1080x2 resolution.[/vc_column_text][/vc_column][/vc_row]
