4k projectors are finally becoming affordable. Optoma today announced the pricing for its first line of 4k projectors. The UHD60 is $1,999 and the UHD65 is $2,499, making these two models the least expensive 4k projectors available. You can send thank you notes to Texas Instruments. Optoma unveiled this line of 4k projectors earlier this year at CES.

These projectors use a new 4k UHD DLP chip from Texas Instruments. Video nerds will be quick to point out that this DLP chip uses a bit of trickery to display the 4k UHD picture. And they’re not wrong. This 0.67 DLP chip employs 4 million mirrors, yet displays 8 million pixels thanks to the mirror’s ability to create two distinct and unique pixels by switching over 9,000 times a second.

Nice. I've had an Optoma HD projector since 2007 that has never failed me, replacing the lamp three times (the most recent being two months ago). Optoma has come a long way in quality. This might be my next projector.

So...it's not really a 4K projector.

The Epson, at $2500 does this same feat by shifting all the pixels one half pixel diagonally, thus doubling the resolution. While it is a great picture, it is not a true 4K.

What is it about dual pixel technology you don't understand? DSLR cameras have been using this for years.
