As one of the 1st people in the UK with the HC3000 my story goes like this:
To cut a long story short (well not that short actually), I returned my HC3000 yesterday after just a week because again this wasn't the right projector for my eyes.
Positives on the HC3000:
Fantastic PQ. The best under the 2K Mark. (3K$ Mark) Very little screendoor. Deep blacks and very well resolved shadow detail. Brilliant Color worked very well giving a lot of extra sparkle and saturation to the colours. Although on some material I preferred it switched off.
Negatives on the HC3000:
Inflexibility of installation. Really only suited to ceiling mounting. Maximum picture zoom low. You really need a bit of distance to get a big picture out of this PJ.
Rainbow Effect - This will not be an issue for some people. But this is the main reason why I've sent this PJ packing. My initial reactions to the RBE on this projector were.. this is bad but I put it down to the fact that I had been ill in the days before I picked it up, had got little sleep and had driven for a few hours on the day I picked it up. I therefore remained non-committal and believed it to be no worse or better than my current DLP projector, expecting the situation to significantly improve after a good nights sleep.
Well... the RBE didn't improve and made contrasty movies like Batman Begins unwatchable. I then started to consider measures that could perhaps help to reduce the RBE like, ND2 filters, lower gain screens e.t.c. It was at this point I also noticed a dead DLP mirror and several smaller DMD imperfections.
The smaller imperfections were not an issue but the dead mirror was. Once noticed, I couldn't help but look for it in bright scenes. It was easy to see and far easier to notice that a stuck LCD pixel. I then made the decision to get shot of my 2nd projector in 2 weeks.. (I returned a Z4 the previous week because the absolute black level was very poor. Blacks were way off. Worse than my old Optoma H30!!)
Perhaps with a few set-up changes, ND2 filter, lower gain screen the RBE would reduce to an acceptable level.. but who knows it may not, and I'm left with a PJ I can't watch with 100 hrs on the bulb. I don't think the retailer would be too happy to take that back.
4000:1 Contrast with a 4 speed 6 segment colour wheel. Why oh... why didn't Mitsubishi improve this area of the PJ design!!!!!
If your eyes can bear it the HC3000 throws a sublime picture. I really didn't want to return it but with the RBE and the dead mirror it wasn't a PJ I could live with. The Z4 for me was a much easier watch but the black level to me was awful.
Oh... well back to the drawing board.
I'm really at a loss now and really gutted having to return the HC3000 because the PQ was outstanding at this price level. The black level of LCD just doesn't cut it for me but maybe I'll just have to take that route and live with the inferior black level.
(Note: Before anyone asks why didn't you demo the HC3000 before you bought it, well I did. I spent 2 hours with it comparing it against the Z4 on a 110 inch greyhawk screen. I saw 3 rainbows in all that time. The combination of a large grey screen and a small amount of ambient light made for a demo room very sympathetic to the RBE. It just goes to show that unless a demo room and screen is an exact match of what you have at home you really can't trust it)
