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.

Color Temperature

The Optoma GT720 had absolutely no problems with maintaining a consistent color temperature throughout the signal range, from dark to bright.

RGB Curves

To get a good sense of color performance, we separately test every value of all three color channels: red, green, and blue. The chart below is the aggregate result. The smooth, gradual upswing starting at the lower left indicates that the projector is capable of showing great shadow detail. Granted, the three channels are not moving in perfect unison – the green is significantly brighter than the red – but as they move up towards mid-tones the channels become one line. In the upper mid-tones and into the highlights (right side) the curve steepens, meaning the Optoma GT720 is displaying less detail.

Overall, it's a strong performance.

Color Gamut

The Optoma GT720 did not match up well with the rec. 709 standard, a common color standard. As you can see in the chart, each of the corners of the triangle – representing the red, green, and blue points – are well off the mark.
