One of the main differences is that the WD-65736 comes with Mitsubishi's DeepField Imager, which is supposed to adjust brightness and contrast automatically to enhance the picture. It also has an additional front HDMI input, and Mitsubishi's NetCommand feature that is supposed to synchronize A/V devices and receivers to reduce the need for multiple remotes. It uses a DLP projector and has a 1920x1080 resolution. It displays HDMI up to 1080p, has video noise reduction and a 6-color Mitsubishi processor. It has two 10W stereo speakers and multiple inputs. It is compatible with Dolby Digital/PCM and audio leveler. It also features the same thin frame from the 735 series. Physically, the WD-65736 looks nearly identical to the WD-65735.
