Optoma PK320 Pico Projector Review
Great peak brightness is offset by an inaccurate color gamut.
Extra noise is not really a concern with pico projectors, particularly with the Optoma Pico PK320. An increase of about 10dB is not much to consider.
At its brightest, the Optoma Pico PK320 shoots out exhaust air that is 45ºF hotter than the ambient texture. At minimum brightness, the exhaust air is only 6ºF hotter than room temperature. This is a pretty big difference, but 45º will not limit your use, only keep in mind that you should leave some room around this projector to keep it from overheating itself.
Somehow, the Optoma Pico PK320, the brightest of our picos, costs the least to operate. Interesting, perhaps, but is the difference of less than a dollar per year going to affect your annual budget? We find that unlikely.
The Optoma Pico PK320 uses long lasting LEDs to project a picture. This particular model is tested for 20,000 hours of continuous use. We did not have the time to do this longevity testing, as we would have had to work nonstop for over two years before producing this one review. We weighed the costs and benefits of doing so and after much deliberation, decided to forgo such brutality.
Optoma does not offer LED replacement. Proper disposal is expected after the lights finally fade, after faithful years of bringing brightness to our world.
