AAXA Technologies P4 Pico Projector Review
This is really no contest. The Optoma PK320 ($429 MSRP) was our favorite pico projector of the four because it hit all the right marks. It had the highest peak brightness, the best port selection, good picture quality, and it was easy to use. The AAXA Technologies P4 ($399 MSRP, about $325 on the web) had none of these qualities, as well as some extra deficits like a self-destruct mode known as the Windows CE desktop.
Blacks & Whites
The Optoma PK320 had a higher peak brightness and a better gamma graph than the AAXA Technologies P4.
The Optoma PK320 had better color accuracy in every one of our three tests.
The AAXA Technologies P4 had slightly better motion smoothness processing than did the Optoma PK320.
Lines were projected more straightly on the AAXA Technologies P4 than with the Optoma PK320, but we saw much more pixel flaring and increasing blurriness towards the top of the projection. They get an equal score here each for having their own set of drawbacks.
The Optoma PK320 had the best array of and easiest access to connections along the back. The AAXA Technologies P4 conversely offered some standard connections, but we had trouble getting all of them to work with ease.
