I'm suprised this hasn't been all over this forum already!
New Dell Projector


What color wheel do you think it uses? It would be a shame if it's only 2X. It also uses the newest DDR controller chip, has the 12 degree mirrors, and seperate HDMI and component inputs. Looks like it could be sleeper for the budget crowd who want a nice high res image without paying >$10K!

It may not be popular here because it is a business class projector. The native resolution is 1400 x 1050 which is a 4x3 aspect ratio. Most home theatres PJ are 16x9 ratios. If you show a widescreen on a 4x3 PJ, you will be wasting pixels.


Business class PJs are usually not optimized for HT. The lumens and contrast specs will be very different once calibrated for HT.


Also, a 2X colour wheel will mostly cause RBE during movies (lots of motion). This is not as important for business presentations (very little motion).

Wow... tough crowd! I guess the days are long gone where this group would be drooling at the mouth to find ways to adopt this for HT! :D


All these 480p $1000 HT projectors must have spoiled us. Remember this is SXGA+ we are talking about!

The 2x wheel hurts, and we need more details about real world specs :)

I guess we need Darin, Mr. Wigggles and Rogo to setup an LLC, OEM this sucker from Dell (kind of ironic), slap in an 8 segment, 5x color wheel and an adjustable iris. Raise the price to $5,500 but with specs like 2000:1 CR @ 3300 lumens or 7500:1 CR @ 750 lumens! :D

Hmm, that's why my 2x color wheel X1 was so very very unpopular here.


Given Dell's history of (sometimes unintentional) discounting I am extremely excited about this - what the Manufacturer actually sells it for is likely to be far different from this announced price. It is also a higher resolution DMD then even the >$3,500 guys have access to - coupled with a nice scaler or a HTPC and this thing could really make a nice setup - 3300 lumens gives you plenty of room for calibration and still maintain a bright picture.


A DMD like this rolling out now (Dell has never shown a willingness to wait on industry release schedules) makes me even more excited for CEDIA and the 1280x768 DMDs - if this can come out at 3499 with that light engine a 4810/x4 level pj at 1999 is not only possible by likely.

Sorry, but the X1 was a different phenomon. All of our choices at that point were 2x wheels :). Now there's a choice. I agree the resolution kicks butt (even if it's 4:3) but that's not all we're concerned with.

huh, I thought there were a good number of 4x wheels in the fall of '03 when the x1 was hot, but you would know better then I.


That being said - I have never had a problem with my 2x wheel - I've NEVER seen a rainbow, nor have any of my guests for movies, football, or sopranos finales - and me a noir movie fan. I have to take it on faith that they even exist. That being said - how much better is the color from the 6 segment 5x wheels? Wouldn't artifacts be more likely with the faster wheels? I'm not saying I wouldn't take one if they priced it the same, but what is the greatest liability of a 2x wheel for someone to whom rainbows are just a ghost story?

While they existed, they were in MUCH higher priced machines. In the Fall of '03 the X1 was at ridiculously low prices (I know, I bought and sold about a half dozen of them!). There was nothing even close with a 3x or 4x colorwheel.

Color is more acurrate and contrast more than doubles. Compare the 2x Infocus x1 with the 4x Optoma H30. 600-700:1 with x1 while h30 was getting 1500:1.

While yes the CR may go up, there was a lot more going on between the X1 and H30 than just a wheel upgrade. They also went from 10 degree to 12 degree mirrors which probably added to CR more.


Mostly a RGBRGB wheel will give you less rainbows, better color saturation and a CR (when HT calibrated) closer to specifications. For instance, even tho this PJ specs out at 2500:1, I would be suprised it was over 1500:1 after calibrating it for HT.

I'll be interested to see if someone decides to purchase this and post a review. I was considering getting the Canon SX50 (same resolution, but LCD in lieu of DVD). 4x3 doesn't bother me since I'd be putting my unused Panamorph in front of it.


I'm semi-susceptible to seeing rainbows, so the Dell might not be for me.

What is this "rainbow effect" you keep going on about - I think it's your imagination.


















See - I'm sure you don't like that - now why don't you stop assuming that a 2x colorwheel doesn't work for the rest of us who don't share your disability. There may be other reasons to not like a 2x wheel, but to dismiss a product out of had that has it is just irritating and immature. My crappy 2x x1 still has a better combination of color and brightness then any lcd i've looked at, and I've yet to see a rainbow. Neither have my guests.

The resolution is tempting (certainly sounds like fun with a Panamorph), and encouraging to see at this price point, but it seems outclassed in other aspects by HT projectors like the 4805. Business all the way.

True. I saw them on a X1/4800, but never a trace with the 4x 4805.

Why in the world are these companies still using 2x wheels? How much money does this save them? Sharp has been using 3x wheels in their business projectors for years and they don't charge more. It seems like they don't want the average consumer to know anything about wheel speeds.
