The Optoma HD33 is a great-performing projector that delivers highly satisfying 2D and 3D image quality at a very affordable price. The inclusion of both RF and DLP-Link 3D synchronization lets the consumer choose from a range of 3D glasses, although Optoma’s optional 3D glasses are certainly affordable enough at a list price of $99. That compares very favorably to other 3D rechargeable glasses currently on the market, which can cost up to $179 or even more. While the lack of color saturation adjustment with HDMI sources is a disappointment, the default color level chosen seems to be right where it should be.
