Optoma PK320 Pico Projector Review
Great peak brightness is offset by an inaccurate color gamut.
We peg the Optoma Pico PK320 as the pico projector to beat. The AAXA P4 has quite a few good features, but can't match the quality, the size, or the versatility of the Optoma Pico PK320. Specifically, the sterling peak brightness of the Optoma Pico PK320 has to be counted as one of the most important specs, as well as having an HDMI connection. Yet, even on the finer points, like grayscale and color quality, the Optoma Pico PK320 is a better device. At this price point, the extra $30 is negligible and pays for a high margin of quality.
Blacks & Whites
The Optoma Pico PK320 was the brightest pico we tested, and it also had the best gamma graph, showing the most detail across the grayscale.
The Optoma Pico PK320 had a more even color temperature, better color transitions, and a more accurate color gamut than the AAXA P4.
In our motion tests (one of our only subjective tests) the AAXA P4 appeared to retain detail in motion better than the Optoma Pico PK320, but they were very similar in their abilities.
Both the AAXA P4 and the Optoma Pico PK320 had difficulties with bowing on the top edge of the picture. The distortion was minimal in both cases.
The AAXA P4 has a great set of connections, but the Optoma Pico PK320 has everything the P4 has as well as that mini-HDMI connection that really takes the cake for versatility.
