Mits HC-100u?

Hello, Mitsubishi's HC-100u won't be shipping until the end of Janaury, but drew positive comments (at Projector Central) based upon CES. In another post, a forum member wrote that a tech at Mits told him that they were using a 2x color wheel. Can anyone confirm this? Did any of you see this projector in action at CES??

I am very curious to find this out myself (color wheel speed). I emailed a vendor that will be selling it end of Jan, and they don't have specifics on that either which is a shame...

Maybe it will operate similar to the HC900U???

The sealed light path would be oh so worth it....I'm tired of dust, of which my current Mitsubishi PJ suffers!

The sealed light path is a major plus. My Sim2 HT-300+ features a sealed light path and I've never had a problem with dust blobs, etc. By comparison, my first projector, the Davis DL-S8, requires regular cleaning.

Here's some more info about the projector from a CES report:
Show Review: CES 2005
http://www.projectorcentral.com/ces_2005.htm

I've sent an inquiry to Mitsubishi regarding the speed of the color wheel. Hopefully the manufacturer, or a forum member, will provide this important bit of information.

That's a good report....

I figure since all these manufacturers brag about a 4x color wheel... and the HC900U on the web sites mentions one.... that if they are NOT advertising a 4x color wheel off the bat... then it must be 2x! If so, what a disapointment....

Contacting Mitsubishi technical support resulted in two answers regarding the color wheel speed. The first answer, speaking directly on the phone to a Tech Support person resulted in the following answer: "I don't know". The second response, received this morning via e-mail was: "The color wheel is 1x @ 7200 rpm". I've responded with a request for confirmation. IF the e-mail response is true, this projector will make Judy Garland roll over in her grave. We're talking major "Rainbow City" here!

Also, Tech Support confirmed that there is no 12-volt trigger on ANY Mitsubishi projector. Those of us with motorized screens will be required to look elsewhere.

If it is true about color wheel on this projector, why would Mitsu. even release it? The rest of the specs are very good and street price would be quite competitive, maybe just a little high.

We just need an 'improved 4805' with lower noise and sealed light path. Even at $200 more this would really be the projector to buy. I would certainly buy it!

LOL! :D Yes, 1x sure doesn't sound right... On another thread someone spoke to Mitsu and they said 2x.... Hopefully they will throw a 4x out sometime next week.. :p It's unfortunate nobody that saw it in CES knows...

Here's the follow-up e-mail response from Mitsubishi Tech Support went I asked them if they were ABSOLUTELY CERTAIN that their color wheel was 1x:
"Yes, all of our projectors are 1x.'

It's hard to believe, but that's their story.

Going to their home site, some of their projectors (and not all that expensive) ..'7-segment color wheel plus x4 color wheel speed richer'. Check it out.

LOL... yea the HC900U uses a 4x.... the case looks just like the 100U ... now thats quality CS.

"The color wheel is 1x @ 7200 rpm".

That equates to 2X effective speed; 60 Hz is 3600 rpm.

at list of $1495. the HC100 looks very good. It discounts for same as h31 and 4850. It has a sealed lite, no filters to change. Only one thing is a downside , perhaps. It has a noise rating of db33..not so good. The best are down to db25-26. Just wish one person had a HC100 to check out noise level. Going by specs, it has better lumens than others at that price..1500 lumens..contrast at 2000, about the same as others. Looks very promising. And check Mits line of DLP projectors. Wonder why we do not hear more about them on the Forum. By the way, best to use numbers (specs) only as a reference (to other projectors) as most are inflated.

Noah, thanks for doing the math. You are, of course, 'spot on'. Sadly, this should equate to more visible Rainbow artifacts.

Several retailers plus both Mitsubishi Sales and Mitsubishi Tech Support have told me that the first batch of 100u's will be shipping "the week of January 31st".

Interestingly, when I contacted Mits about the projector I was transfered to a person in their Presentation Products division rather than Home Theater.

..around Feb 1 I am buying a projecter. Been considering a 4805 or h31. Maybe I should also think about the hc100..looks promising. A sealed lite path sounds good to me. Shipping week of 31 January will be late for the Super Bowl, it seems.

..begins to seem all contenders at $1500 (list) level have one flaw. The Infocus 4805 can be loud to some; the Optoma h30 can have early bulb failures for some; the hc100 seems to have a color wheel not as fast as others at same price.

If a 1x wheel is 3600 RPM then a 2x wheel should be 7200 RPM. Since the HC100 has a 7 segment wheel (RGBRGB?) then it should really be a ~4x color wheel. It was my understanding that all of the 4x color wheels are really 2x with 6 segments.

I purchased a Mitsubishi XD450U for work and set it up and it seems like a really decent projector. It could be a little quieter but the sealed light engine is a definite plus. I can only hope that the HC100u really is a 4x and the marketing department is confused.

I found this quote from "DJHOTZ" in another post. If the info in here is correct, then based on the the 3600rpm info above, it would be a 4x wheel.

"doing some more research for myself and everyone else. I called mitsubishi and spoke to a representative who called the engineering department to get this info for me. the fan noise is 33db. Now here's the sad part. He said the color wheel was 2x 7200rmp. Really bums me out. I was pretty set on getting this projector if it was a 4x color wheel. Guess it's back to buying a trusty 4805 for me. To me for the image difference between the h31 and 4805 doesn't justify the extreme difference in dependability of the two. Make your reliability better Optoma and I'll be your customer. Till then....."


If this is the case, then the HC100U could be quite the sleeper in entry-level DLP projectors. I called a couple of vendors and they are available and shipping. Can't wait to see a review.

Just wondering if anyone has heard anything more on this projector?

I e-mailed Mitsubishi's customer support asking (a) what the noise was in "low" lamp mode (~80% brightness), and (b) what kind of color wheel the HC100U had. I got a call back the next day (today) and (a) it's 29dbm vs the usual 33dbm, and (b) it's a 4-segment color wheel (RGBW) rotating at 7200rpm.

That sounds disappointing to me. I'm looking at getting the Optoma H31 from Costco.com at this point...

On one of the "preferred vendors" website for the mitsubishi HC100U it lists that the color wheel is 7-segments...???

Called them, they said that the info came from Mitsubishi no idea on the speed, but they don't have it in stock yet.

Are they holding off this one to sell the 900 instead...???

We have several other projectors under review at the moment, including the Canon Realis SX50, the Mitsubishi HC100, and the Optoma 739 which many of you have been continuing to ask for. We have a lot to report on these units, and we'll get the reviews posted as soon as we can.

escape how's the picture quality and how does blacks look i;m torn between this projector and the new toshiba 7700 let us know the rundown and could you pm me and tell me where you got yours and at what price thanks
post #26 of 33

Someone from Mits just left me a message saying that the 100u has a
7 segment color wheel turning at 7200 (2x if I'm right).
post #27 of 33
4/4/05 at 10:21am
If you read my previous post...all 4x wheels turn at 7200rpm. It is the number of segments that make it 4x. Instead of RGB the wheel is RGBRGB therefor it is updated twice as much as an RGB at the same RPM. I don't think you would want to buy a projector with a colorwheel that spins at 14,400rpm. There would be a lot of heat and noise associated with that kind of speed. If it is indeed a 7-segment wheel then it will be considered a 4x speed. I doubt they would use a slower electric motor just for this one projector when all of the rest of them use a 7200rpm part. The economics wouldn't make sense.

Hopefully the review by projectorcentral will reveal the actual specs on the projector.

Projector Central gave this projector an excellent review, and said they see less rainbows than other 2X color wheel projectors. Has anyone bought this yet? How do you like it?

well i'm very happy with this projector and it is very quiet even with everything turned off you barely hear it , and the picture it puts out are very impressive everyone that has been to my house said they are impressed with the picture it puts out..

Any new opinions about this projector? I'm trying to debate between this one and the HC900U; but the latter model is louder, which I'm not too fond of.

? :)
