I was fortunate enough to be invited by Stuart Acey of Optoma to go along to Jeff Paynters place (RTFM from this forum) and view the new H78, so I could see the improvements the upgrade has over the H77. I took along a USB2 mobile hard drive with some torture scenes on it (not literaly) so that I could plug it into Jeffs UVEM HTPC and see if the improvements were visible. After fireing it all up and setting the white and black levels correctly (PowerDVD 6), we were up and running. The first test was the posterisation scene from U571, and that passed with flying colours - the recent H77 firmware had fixed this but we wanted to make sure it was still fine. The next test was a sequence from LOTR which had sometimes produced the 'clay face' artefact as the group walked passed the camera. This was still a minor failing with the H77 but now the H78 rendered it with no problems. The next two tests were for the panning artefact which the H77 still suffers from in varying degrees, and last week I'd tried a computer generated movie sequence which a guy had sent to me from the US (it was so bad he wanted to know if it was visible on H77s over here). It rendered quite badly on my H77 with very obvious banding being apparent, so this was to be a real test for the H78 (I personaly hadn't noticed the artefact elsewhere on other movies though others had, but this scene was particularly bad). Instead the motion was smooth with the artefact being barley perceptible, in fact I wasn't sure I was seeing things but no-body else new what they should be looking for, I think they thought I was making it up. Another scene which had been mentioned was the scene from Spider-Man 2 where Peter Parker drags his broken motorcycle along a wall of Mary Jane posters - the poster images were said to break up quite badly, but with the H78 there was absolutely nothing out of place at all. Very smooth in fact. It seems Optoma have become aware of the issues some had mentioned with the H77 and made a point of fixing them - good product support IMHO. The question is, is it just firmware? I was told by their Product Manager Justin that part of the upgrade is firmware (Version 17), but they've also improved the sequence codes in the DMD controller (from TI themselves apparently), along with some improvements to the lamp modulation control - and this is where the extra brightness comes from. The later needed a modified board IIRC, so some components are new. I can't remember if the TI mods were chip upgrades or not, but it allows for faster switching of the mirrors. We watched som Hi Def material from Jeffs UVEM as well as various DVDs to see how the image looked, and everything looked very good. Now that I think back - I didn't notice any noise in the image. With my H77 some image noise not unlike film grain was visible at various times, but this had gone with the addition of a lens filter and as the lamp had aged. Whether the noise was there and I didn't see it on the H78, or the modifications had fixed it (I have seen similar noise on other HD2+ DLPs), but with a new lamp projecting an image approx 7.5ft wide I didn't notice it. We didn't have time for me to measure the lumens from the H78, or check the contrast ratio, but with the improvements seen elsewhere, I'm looking forward to getting my H78 back so I can see if the numbers I'd measured last night have increased.
