Introduction

We get asked fairly regularly to review more budget-minded products for our readers. In particular, everyone seems fascinated by the influx of lower-priced front projection systems that are competing for a large financial portion of the home theater display market. These front projection systems promise large viewing screens with an almost unbeatable price point. Compare, for example, a 92" front projection DLP system vs. a DLP-based rear projection unit and you are talking a potential savings of over 60-70%! It doesn't take a Nobel Lauriat to figure out where the bargain is. Sure there are trade-offs, mostly in terms of ambient light management and viewing distance, but if you can overcome these obstacles then you are looking at a tremendous opportunity.

…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.
