| Personal Experience |
| The HD72 came right out of the box easy to set up and program with the remote. The tripod mount was a bonus, since my Optoma ceiling mount was on backorder. The operation manual left a little to be desired, like details about how the image shift was designed. Using component video and DVD source, the image was stable with good color balance and contrast right out of the box. Brightness in the cinema setting demands little or no ambient light. At a 92" diagonal, the sharpness left a little to be desired. It was likely secondary to the source and my level of expectation. I found myself constantly trying to focus. Follow the projection calculator carefully before selecting this projector, installation is somewhat limited. Overall, very excellent bang for the buck. See problems below. |

| Problems |
| On initial setup, new hum/noise in the audio circuit of my AVR3805 Denon Receiver was a major hurdle. The projector also emits an audible high-freq whine when on which reminds me of a CRT. The component video is connected to the monitor out of my receiver as normal--all wires tested OK. Even bringing the projector AC to the same distribution center as the receiver did not rectify the problem. I floated the ground using a 3-to-2 prong adaptor on the projector and 50 percent of the hum went away, but put your ear close to the tweets, and it's still there. The chassis now has a common ground with the receiver through the component connection. I tried multiple hook up scenarios and ground locations, and no matter what I tried, there was irregular noise in the audio system directly related to the projector either being "on" OR on "standby". This might be complicated by the fact that I don't use the Receiver to amplify all channels. My next solution is to disconnect the AC ground on all secondary amplifiers, but I really don't want to do that. Bottom-line is that the projector was the only variable when the hum presented, and it goes away when the AC rocker is off on the projector. I am preparing to use it connected directly to the source to eliminate the headache all together, but then why do I have a receiver? Awaiting Optoma's response on the issue via web. |
