You can break 4K solutions into three categories. Tier 1 4K projectors are typically products from bigger brands with far more advanced features than the average user needs and cost over $5,000. We also have the Pretenders where you can fit in many “faux-K” projectors – they project pictures that are of better quality than your standard UHD projector but rely mainly on pixel-shifting technology rather than native 4K devices.
We would class the ViewSonic PX748-4K as one of the In-Betweeners. This category is for people who want to enhance their viewing experience with native 4K without breaking the bank for the advanced features that come with Tier 1 4K projectors. The PX748-4K provides the best value for money for non-technophiles who want true 4K projection. It is also a great 4K gaming projector.
