Optoma HD20 DLP Projector Review
There's plenty to be excited about in the Optoma HD20. It's a 1080p projector for under a thousand dollars.
The Optoma HD20 produced smooth motion, for the most part, but certain types of pictures and color combinations gave more problems than others. For instance, a human face smeared and lost detail, but large blocks of contrasting color, which frequently cause headaches for TVs, was fine here. However, high frequency black/white patterns appeared quite jagged.
One of the issues with DLP projectors is the distinct rainbow pattern that appears if you move your head to fast, or wave a hand in front of the projector. It can be either dismissible or nauseating, depending on the viewer. We recommend trying one before you buy. The Optoma HD20 definitely turned our stomachs when we displayed a black & white grid pattern, but how many of those do you see in a movie?
3:2 Pulldown & 24fps
The Optoma HD20 has no problems with 3:2 pulldown for native 24fps content.
The Optoma HD20 has almost no problems with resolution scaling. The native 1080p display means it's designed specifically for NTSC resolutions. Depending on how you have your keystoning set, you may notice some funky, curved lines in high-contrast, high-frequency patterns.
