Optoma HD66 Comparison
- Optoma HD66 is $100 cheaper than GT720
- Optoma HD66 is lighter and more portable
- Optoma HD66 has lower resolution, but more attuned to HD video
Value
The Optoma HD66 has a native 720p (1280 × 720) resolution, making it ready for HD video straight out of the box. The Optoma GT720 has a hard time rescaling HD video in all its formats, so the HD66 is looking better already. The HD66 is also smaller and lighter, making it more portable than the “portable gaming” GT720. Overall, we’d have to pick the HD66 as the better value.

Blacks & Whites
Both Optomas offer great brightness, so you shouldn’t have problems in dark to moderately-lit rooms. The Optoma GT720 definitely had more problems with maintaining a consistent black level, but we were pleased overall with both projectors.
Color
The Optoma HD66 showed some unusual results in the color curves test (the red channel peaked early, losing detail in the highlights), while the Optoma GT720 was more normalized. Overall, the Optoma GT720 is the better color performer, provided you put it in Cinema mode.
Motion
The Optoma GT720 has smoother motion performance than the HD66, but they have approximately the same amount of artifacting.

| Motion Smoothness | 6.0 | 4.75 |
| Motion Artifacting | 6.13 | 6.25 |
Viewing Effects
The Optoma GT720 has a short throw and no zoom lens, making it less flexible than the Optoma HD66, which has a longer throw and 1.1x zoom.

Connectivity
The Optoma HD66 has a VGA output, which the Optoma GT720 lacks. Otherwise, they are the same.
