Optoma GT720 DLP Projector Review

On the whole, it's a good projector, but if you're serious about gaming we'd recommend looking for something with a 720p or 1080p native resolution.

Motion Smoothness

The Optoma GT720 generally produced a very smooth motion performance. Images with fine, complex detail will show break-up more than areas of flat or little detail, as you might expect. Overall, we noticed a slight stutter in moving images, but it wasn't too bad. Strictly speaking about motion smoothness, there was no difference from one resolution to another.

Motion Artifacting

Artifacts are anything you see on the screen that weren't in the original signal. Different display technologies all have different artifacts. With the Optoma GT720, we noticed some bad sharpening and color shift around areas of high contrast. The artifacting was more noticeable in the 1080p resolution than in the native resolution.

3:2 Pulldown & 24fps

The Optoma GT720 has no specific modes or processing features to aid in the rendering of native 24fps content, but it can display it effectively enough (some projectors can't handle 24fps at all). In testing, we noticed that the GT720 showed some problems with high frequency patterns, and some slight stuttering when the camera pans horizontally. Overall, though, it was rather good.

Resolution Scaling

The Optoma GT720 has a native resolution of 1280 x 800 (WXGA), but is technically capable of handling all standard video resolutions. It's up to the projector's internal processing to scale the video signals for display. Overall, it's not very good at this task. This is significant for gaming systems, which are 1080i and 1080p, by and large.

480p

When we fed the Optoma GT720 video in the 480p format, we saw no problems. This was the best of the three resolutions.

720p

With 720p content, the Optoma GT720 showed major problems with high frequency patterns. There was an incredible amount of Moire. Also, fine text was difficult to read.

1080p

With 1080p content, we saw exactly the same problems with Moires in high frequency patterns. However, fine text was easier to read.
