Since the projector’s native resolution is approximately 2.3 MP, it won’t be as sharp/detailed as a true 4K projector (8,8 MP resolution). While a Pixel Shifting HD projector does deliver more clarity, it still can’t match the resolution provided by a native 4K projector.
Pixel Shifting also requires a lot of processing so it can’t be combined with some features like edge blending and Creative Frame Interpolation but even some more basic things, including some types of noise reduction cannot be utilized.
So how do I choose between a pixel-shifting projector and a true 4K projector? To make a wise decision you must factor in your budget, what you are watching, and from where you are watching it.
True 4K high lumens projectors cost at least four to five times as much as their 2K counterparts. Consider this, an 8,000 lumen true 4K laser projector can retail for $60,000 while an Epson pixel shifting 16,000 lumen 2K laser projector costs about 1/3 of that amount. This will be true until we see dramatic price drops in the true native 4K projectors to make them more price competitive. True 4K projectors are going to be hard to justify in most situations even when 4K content will be used.
In many situations, the content lacks the detail required and is viewed at a distance where the difference between 4K and pixel shifting cannot be perceived. While pixel shifting can’t match the resolution of a true 4K projector, it does increase sharpness and detail compared to a standard 2K projector.
So, if the image is going to be viewed from fairly far away, a brighter, less expensive pixel shifting projector might be a better option. In many situations the benefit of extra brightness far exceeds the benefits of additional resolution.
