Optoma H31 Calibration & Bench Testing

Calibration - Get Those Black Levels Right!

image007_003.jpgIt is very important to set the black and white levels (Brightness and Contrast) in order to get the most out of this DLP projector. Forsake this and you might as well keep the lights on in the room. Utilizing the Datacolor ColorFacts CF6500 I tweaked the brightness (black level), contrast (white level), saturation (color/chroma), sharpness, and hue (tint) to accurate levels in the user menu. Before I performed the ISF calibration I reset the projector and took some measurements. The biggest adjustment we made was in the black level setting which was set much too high in the default settings. Once we adjusted black level, all of our ramps looked much better and viewing images on the H31 started to really produce impressive results.

The Datacolor ColorFacts CIE Chart is used to display the colors for the Optoma H31's HDTV color reference, as well as the gamut of colors that it is capable of creating. Here you can see the projector reproduces excellent greens, but has some issues getting into deep blues and reds. Bringing up images on the display showed only pleasing results with no lack of saturation apparent in real world film content.

Here are some of the before and after measurements as shown by the Milori ColorFacts Professional 5.5 software:

Comments on HQV Testing

Running the HQV tests on the Optoma H31 allowed us to see how well the projector's video processing did in a variety of tests. Overall, we were pleased with the results, though the internal deinterlacer could benefit from some better processing for dealing with multiple 3:2 events that are layered with either video effects or highly detailed scenes. Noise reduction on this unit was minimal with lots of noticeable noise making its way past the processing and into the picture. Of note, the rather difficult Film Detail test was passed with no trouble at all - this test tripped up more than a few players we have encountered. Overall, we would probably recommend using a high quality progressive scan DVD player with the Optoma projector to achieve the best results. If you have a mediocre player, then you may want to experiment with the Optoma's deinterlacing versus the player's to see which is better. New budget DVD players on the market with HDMI or DVI should be used with this digital connection for best results.

…I think the setup disk might be the way to go for me, is the avia better than the essentials setup dvd? I was trying to save myself the step and the $. I am fairly new at all this, i was not sure if I just adjusted the brightness and contrast levels and left the advanced adjustments alone if the picture would be clear and crisp…

IMO, the Avia setup disc is a bit easier to navigate than DVE. I own both however. Considering the time and money you've invested so far, the costs of the DVDs are well worth it. I doubt you'll need to go into the advanced measurements area. Between contrast, brightness, color, tint, & sharpness. You'll more than likely be very satisfied with the picture. Since you are just starting out, the truly advanced measurements are best left to trained A/V professionals.

H31 calibration

I understand that everyones room is different and some settings would be different, I guess I am trying to get some input on brightness and contrast levels, as well as the rgb brightness and contrast levels. I think the setup disk might be the way to go for me, is the avia better than the essentials setup dvd? I was trying to save myself the step and the $. I am fairly new at all this, i was not sure if I just adjusted the brightness and contrast levels and left the advanced adjustments alone if the picture would be clear and crisp. Some specs on my system, I have a DIY 115 inch screen and my projector is back 18ft, everything is dvi and hdmi, ps3(bluray) and I have a yamaha rx-v1700 receiver, with full B+W surround sound, expressvu HDTV.

Which settings in particular are you looking for? Do you have the Avia setup disc? You'll need to set the unit up within the context of your current room, screen, gear, etc.

Using someone else's setting can make the image display look worse, not better. The avia setup cd takes about 15-20 minutes if you take your time. I have the H30 and I usually adjust my every 250 hours on the bulb.
