Just my impressions so far...
For anyone else considering upgrading from an older projector, I received mine yesterday (shipping NY to SD in 22 hours - i need to learn patience
), i'm very happy with it so far. I had a VPL-VW50 before (with about 500 hours on it's 2nd lamp), and so far the HW30 seems a lot brighter (in low lamp mode it seems much brighter than the 50 was in high mode!), also the blacks look 3-4 time darker. I have no calibration equipment so that's totally subjective. My screen is fairly old 106" diagonal Draper - not sure what gain, and i had considered upgrading to one with higher gain to help 3d brightness, but from what i've seen so far the 3D is plenty bright on brightness settings 2,3,max. min and 1 are fine but maybe a little dim. This is with less than 2 hours on the bulb though.
Ghosting is very minimal and not bothersome. Strangely, what ghosting there is i have not found is affected totally by the brightness controls. Ghosting on Min setting is still visible, i'd have to guess this is now due to the LCD glasses not blocking out 100% of the light when they're opaque, rather than the timing being off. I haven't tried yet, but if so i guess i should lower the brightness of the projector and increase the glasses brightness to compensate. Has anyone else tried that yet?
Noise seems slightly lower than the VW50. the mounting holes are exactly the same as the VW50 (so it worked immediately with the home-made ceiling mount i made).
I had to do some panel alignment, but the alignment menu worked great, very accurate small steps and the end result is good.
I miss the motorized focus, but once this is set correctly it won't be moved so it doesn't really matter. It's really nice having the horizontal shift, which the VW50 did not have. My projector mount is less than 1" off center which always resulted in a very slightly bigger picture at one side than the other, but this issue is fixed now. My projector is mounted as close to the screen as possible, which i liked 'cos it helped boost the VW50 brightness, and the VW50 was always zoomed at maximum. It seems like the HW30es has maybe a slightly higher zoom, but it's withing a couple of percent.
So far i've only tried it with Rango (2D), Tron(3D), Piranha(3D).
