I read an intriguing bit of information on the new Dell projector on Forbes.com today...
It looks good but only has a 280::1 contrast ratio.
You can read more about it here.
I think the NEC LT-150 or LT-150z with Guy Kuo style modifications is one of the better tickets to inexpensive FPTV happiness, without going to CRT which is too large for most people to accept in their home theaters.
I've done the Guy Kuo mods, and the difference is astonishing. I did a test, with likely bad results that garnered a 2000:1 contrast ration. I sincerely doubt that this is accurate.
The downside is the fan noise -- you will require a hushbox to conquer it, or mount as far away as possible.
In my environment, I was unable to put the PJ anywhere but directly overhead, and with some effort on my part was able to get an acceptable solution, with a Whisperflow hushbox.
Another hot PJ is the Panasonic AE100.
Just some food for thought -- good luck Lee.
I'd wonder what the rainbow was like on this projector with a price like that.
I'm hoping that the Plus Piano company will come out with a newer, brighter version of the Piano with less rainbow (maybe HD2 chip).
Also for cheap bang-for-buck the panny ae100 sounds like a winner.
Who knows though...maybe this projector will end up having better contrast than it has on paper when it arrives.
Thanks for the comments all.
I am intrigued by the Panny model.
It just seems to me that with current technology, someone should be able to offer a $2,000-2,500 projector with good video color, reasonable contrast, and still make it portable enough for my PowerPoint business presentations.
I have had trouble finding a Plus Piano dealer in my neighborhood, but the recent reviews have been mixed.
We may see better number on the Dell unit since it seems many technical stats were missing. I agree that 280:1 seems too low to be useful.
How much is the NEC with the Guy Kuo mods?
It's probably the Optoma 735, more info on the Dell 3100mp thread:
The Guy Kuo mods you have to do yourself. Parts cost? Maybe $10-15. There were a series of discussion about this, mostly dealing with cleaning up light spill and color correction to pull down the inherent green push of the projectors bulb.
The differences in my setup were pretty astonishing, and I am using nothing close to a "reference level" video setup.
Though more expensive, the HP XB31 seems to be an excellent choice.
HP XB31 projector
And don't forget about the Panasonic 75U and the more expensive 711XU. They are XGA (1024x768) and 4:3, which is better for PP and business than the AE100 which is only SVGA and 16:9...
I happen to have tested the Dell 3100MP myself over the weekend, and was impressed with the quality for such a small unit.Needed a pretty dark room to get a good picture. The Dell is made for business first place, not for HT, and that is what it's good at.
That being said, I am a newbie, and need to make up my mind very soon about a projector. No matter how adequate the Dell would be for me, small is not #1 priority, and I'd rather have something with a better contrast ratio/light output. Have about 2500K to spend, these are some options that I considered:
Panasonic PT-LC75U, very good reviews, 1200 lumens, XGA, 400:1 contrast
Boxlight CD-600, 2000 Lumens, great!, but only SVGA, what's the downside of that?
Anything else I should consider?
I'd consider viewing the NEC LT150Z or LT154 as well.
The Boxlight CD-600 is actually the Infocus LP500, simply rebadged. You may be able to find the Infocus for less:
One good thing about this projector is you get Faroujda's DCDi chip, for excellent video quality. Also (though I've never seen it), because it uses a 270 watt SHP bulb, I'm guessing reds will be very strong on it. My projector uses a 270 watt SHP and I've found it to have naturally very warm colors too.
One issue with 800x600 is there will be some slight downscaling when watching DVD's. Most DVD's have a native 16:9 resolution of 852x480. With an 800x600 projector, you'll be watching at a downscaled 800x450.
if you want DLP and don't mind some rainbows the NEC LT150 is exellent with a HTPC.
If you don't want to go HTPC and you want native 16x9 and can sit far enough away that screen-door issues won't affect you, go for the Panny AE100. Don't even question it. If you only have $2 k to spenk on a projector, I think you can get it shipped to you total for less than that from Japan.
I see that the LT150Z has a 800:1 contrast ratio, and 1000 lumens. That seems like a very good ratio, is that what makes it good? Or would brighter be better
It really matters what size screen you're looking to project it on, how much ambient light control you have, and if you and your significant other (and friends) are succeptable to rainbows.
A properly modded and calibrated LT150z can do easily over 1000:1 on/off contrast.
What about viewsonics PJ350 projector? ...... its xga i believe and touts a 800:1 contrast ratio as well ...
on their web site it mentions 1100 lumens and 500:1 contrast. Anyone any experience?
The Viewsonic PJ350 is actually the Sharp Notevision M15X. Boxlight also buys it and markets it as the Boxlight XD-17k.
XGA native Single chip .7" DLP
500:1 on/off contrast
1100 ANSI lumens
38dB of noise (boxlight claims 35dB)
2000 hour 130watt P-VIP bulb
3.3 to 3.5lbs
At about $2800-3400, might not be the best choice. BTW, the M15x has been sort of "one-upped" by the new M20x, which gives you 1500 lumens, 1000:1 on/off contrast (800:1 ansi contrast), at the same price.
