HC900-H57-HC2000-Proj. Design 0.5 compared
Yesterday we did a shootout between the following projectors:
Mitsubishi HC900
Optoma/Themescene H57
ProjectionDesign 0.5 (Pjd)
Mitsubishi HC2000
Using PAL DVD discs and DVI players enabling to connect all using DVI. The first three are matterhorn DLP's 1024x576 resolution and the HC2000 is HD 1280x720.
First I will give some impressions after going back and forth between the various models. Using the opinions of myself and the others. All pj's were first calibrated to the source with DVE. No grey scale calibrations were done so as to establish an out of the box comparison.
I will list various categories and the list from best to least good where / means equal.
Picture quality impression.
Pjd 0.5 HC900 HC2000 H57
Close to call, but resolution has the edge, not much difference here, HC2000/HC900 were quite pleasing. H57 has quite bright whites, although impressive it seems that you notice a bit more rainbow. Since it has no sort of iris and I haven't found a way to control the white segment, that makes the other ones a tiny bit more pleasing. But if you like a striking picture the H57 is king.
Color
There are just so many options in each of these machines that it seems unfair to give some conclusion. My opinion though favours H57 (jumps of the screen the most), bright reds. HC900 and HC2000 very good colour less pronounced. Pjd is very good not much comment comes to mind, maybe red seemed a bit brownish.
Scaling (576P)
Pjd 0.5 H57 HC2000 HC900
The Pjd stood out to be just perfect, every resolution pattern was tops. No overscan anywhere.
HC2000 and H57 are good, no overscan, good resolution pattern. H57 over HC2000 because playing 576P gives better resolution on the H57, the HC2000 needs to scale and thus details normally one pixel are for example scaled to 1 or 2 or 3 pixels, just not 1:1. Easy to see. Of course when HD is used HC2000 gets the edge and will win.
HC900 was just unsatisfying, 15-20 pixels overscan left/right and 5-10 top/bottom over DVI! Resolution patterns are way unclear.
Deinterlacing
Pjd 0.5 H57/HC2000 HC900
The faroudija realy does the trick, H57/HC2000 are good, HC900 is ok but in detail quite edgy and flimmery, really needs progressive DVD players.
Focus/Sharpness
Pjd 0.5 HC2000 HC900 H57
The Pjd has very good optics, sharp and focussed all around, HC2000 and H900 are almost up to the Pjd and the H57 has a focus issue, center is sharp but near the edges it becomes a bit softer, will be fixed by Optoma, might be a batch error.
Black level
HC900/HC2000/H57 Pjd 0.5
The HC900 HC2000 H57 are too close to call, the Pjd 0.5 is just a tad worse, but add an color or nd filter and you are a happy camper.
Contrast (impression after basic DVE calibr.)
H57/HC2000/HC900 Pjd 0.5
The H57 is quite bright, just visually it has nice contrast, it jumps off the screen the most. HC2000 and HC900 are quite alike but a bit more "calm" or smooth, the Pjd 0.5 is just a bit behind.
Noise
H57 HC2000 Pjd 0.5 HC900
The H57 is near silent, the HC2000 as quiet but adds a tiny high pitch, then the Pjd also with a high pitch but really a bit louder. The Pjd has long throw, so it can be placed behind you, easier to ignore the noise. Last the HC900, makes me remember a Benq data projector.
Rainbow
Pjd 0.5 HC900 HC2000 H57
Pjd was very controlled here, HC900 seemed up to par, but better than HC2000, H57 was a bit bright which make you see them a bit easier, but if you are not paying attention to it, most people won't really notice.
Posturerising (using some sequences from 5th element superbit)
HC900 H57 HC2000 Pjd
HC900 was a bit better than H57 (both had little but HC900 was a tiny bit more steady when we saw it) HC2000 seemed almost equal to H57, but better than the Pjd, that had quite some of it. You really have to look for this DLP disadvantage though and you need trained eyes to really detect it.
Size (for the record )
Pjd 0.5 HC900 H57 HC2000
The HC2000 is just plain big. But then again silent as well, and the Pjd is not.
Price
The HC900 is a bit (say 200-500$) cheaper here than the H57, then comes the Pjd with a substantial difference (more than 1000$) then the HC2000 with the same substantial difference.
Conclusion:
Since silence is king and taking budget into mind the H57 gets the edge, but must be free of the optical focus issue. HC900 has a very nice picture but the noise and overscan is just placing it behind the H57. The Pjd 0.5 is very good, you get really much quality, optically and technically but the noise and price place it behind the other two. (If the extra$$ are no issue, add a colour/nd filter and a hush box and it is the best ) The price of the HC2000 makes it interesting if you can let it shine using HD sources. DVD sources will not benefit much if any compared to the matterhorns and PAL scaling doesn't make it better. 1:1 pixel projection for PAL dvd's is surely king.
Comments during the evening:
The HC900 picture was favoured over HC2000 using PAL dvd's.
HC900 picture was noticed to be a bit sharper than H57 (H57 has the edge electronically (scaling) by a good margin, but the optical system seems to need a fix in this H57 demo model)
During the demo, those who have not had a projector before seem to care less about noise, they seemed to favour HC900 over H57.
But for me knowing the overscan of the HC900 and the noise level I favor the H57.
I saw the H77 too on another occasion, only beats the H57 using HD |
