AAXA Technologies P4 Pico Projector Review
To test smoothness, we look at detail retention by moving a set of standard pictures back and forth. We saw excellent detail retention in all of our pictures. There was a small amount of blurring, as there always is, but faces were wholly recognizable, tight lines stayed separate instead of banding together, there was no noticeable color trailing, and high density patterns remained sharp.
In two out of our three tests, we saw almost no noticeable artifacts. Artifacts occur when a device cannot accurately display a moving object and add aspects that were not part of the original signal. The only problems we saw were with high density patterns, which became distorted as they moved. Instead of retaining a rectangular shape, these patterns slanted into a parallelogram, showing us that the refresh rate of the processor was not fast enough to match the motion of the object.
We had some trouble with different resolutions. Though we were encouraged to try an 800 x 600 picture through the VGA cable, we got a message on the screen that this resolution is not supported. We tried a 720p picture, and this did not work either. We were able to get a 1024 x 768 picture finally, but this had many problems. Immediately, we saw about 2% overscan all around the picture. This overscan forced all of the moire patterns to band together. Readability of text was difficult and only half of our high resolution patterns were properly displayed.
Considering that the only other option for displaying pictures is the AV port, the VGA is the primary input for the AAXA Technologies P4. We found this primary input quality to be disappointing. It lacks flexibility in resolution and setup. We could not get a picture until we preset the screen to the proper resolution, and we had to try a few different ones before we got something that worked. This will make presenting difficult, not something you want to face when you go into that important meeting.
