Been looking around and waiting for this type of deal.
Just bought the last one at Broadway with an extra $100 off. Woohoo!
- Note that according to Projector Reviews: The TK850i uses a 0.47” DMD DLP projector that creates a 4K image through the use of pixel shifting. Pixel shifting uses a native resolution 1920×1080 sensor to fire the same pixel four times, shifting where it hits the screen slightly each time, to create a total of 8.3 million distinct pixels on the screen.
BenQ advertises the product as "True 4k"
