Sim2 Lumis Owners Thread - Page 54

CM,

What are 'mains' you're referring to? Unplugging the main power cords (HOST and Lumis) from the wall??

I'd like to try this.

Thanks!

Yes, household power.I was addressing an international audience

I used the term "Hydro" s a kid, but when I stated working in the US no one knew what I meant.

Gotcha, eh!?

Well, if this does it, I guess we can assume this pumping is a software related issue rather than a failing hardware problem.

Thanks!

Seems to have worked for me. Two days. No visible pumping. First time since I've had the Lumis.

I did the re-do last week. Haven't had time for a movie yet. Cool.

I'll have to watch " The Blind Side " now as a test.

Glad to be of assistance.

Word! i still have problems with words nobody seems to know

A toque is a hat,
a chesterfield is a couch,
and it is pronounced 'zed' not 'zee', 'zed' !!!!

CM,

You da man! My dynamic iris had become so bad, I had to disengage it.

I have watched 3-4 movies since following your Dynamic Iris fix protocol (above) and my dynamic iris is fixed!!!

No issues what so ever. I actually forgot it was broken and had to check my menu just to see if I even had Dynamic Iris engaged.. I did!

Thanks!

I am thinking of buying Sim2 lumis for 12-13 ft wide 16:9 screen . I talked to my local dealer and he told me that lumis is not meant for that big screen and I will need 5000e. I will like to get opinion of the lumis owners. My theater won't we done for another 2-3 mths.
Thanks

Looks like revenue is down for your dealer.. I have a 14' wide scope microperf that lights up like a champ with one Lumis.

That said, to get max light output, place the Lumis at the end of it's throw such that the lens is wide opened. I am at the very front (2.7ish) of the T3 lens throw.

Two projectors would be a headache to place and converge... I'd get a bigger output model like the HT5000.

Thanks for the input. But my screen will be 16:9, so even 12 ft wide screen will have more surface area to light , than 14 ft wide scope screen... 87 vs 84 sq ft. So is that the limit for lumis to comfortably light the screen without compromising black levels , contrast and the "pop" . Also it will be important to have some headroom to account for aging of the bulb!

True but add 10% screen size to my sq footage due to perfs and my screen is net larger (92.4 v. 87)...

UHP drop off is not like xenon. I have not noticed much light drop off and I'm at 400 hours.

But if you want more and need headroom, just buy the 5000.

Hi Jeff

My screen will be AT as well. I definitely dont want to spend any more than Lumis. I was fairly confident reading through all these posts that Lumis will be able to light 12-14 ft 16:9 screen without any problem. Its only after talking to the dealer I am having doubts. He is selling Demo HT5000 at lower price than Lumis (Its not 5000e). So i gues its not money -... thats why I am second guessing my decision now.
But if you say that Lumis is lighting 92 sq ft AT screen with enough headroom left with no compromise on black levels and POP , than I do feel more comfortable.
IS anyone else using it on bigger screen??

Thanks
Mani

I think my screen is the largest.

If you want max light, you have to have it at with the minimum zoom at the 2.7 end of the T3 lens, for example. If you are zooming into the screen, it will limit the light output (but inc CR).

So where you mount it is critical for you since you need light output.

If you're near Detroit, come on out and I'll demo it!

Hi Jeff

Thanks for ur offer. I used to live in Harper Woods till about 8 yrs ago, but I am in Phoenix now.

Your dealer has a very expensive out of date display model that he is dying to get rid of. He may be giving you his honest opinion, but it also happens to be self serving.

What's the bottom line on this projector? Is it still worth considering at this point or wait for CEDIA/CES?

It's is an excellent pj. Perhaps the best. Butid still check CEDIA..

Hi Shawn, what is the manufacture date on your C3X1080 ? -
Thanks

Just got my Lumis back from SIM2. I couldn't do a firmware update as my projector was one of the first out, and needed a hardware update to take the current firmware. Had them put a new bulb in too, as I always felt my original bulb was not as bright as others reported theirs were. Everything works and looks great !! No more menu freeze, and with the manual iris closed and the bulb power at its lowest setting, we are back up to 26 foot lamberts - just where I like it!! Kudos to SIM2 and AV Science for great service!!

Also, that trick of turning off the dynamic iris and turning it back on really works great. No pumping at all with anything other than " The Blind Side ". Watched " The Blind Side " and while there are about 12 scenes that do something weird ( I wonder if those scenes pump on other DI projectors ? ) the rest of the movie looked great.

Still necessary after your service?

To what do you refer, the DI on / off trick? Everything is working great right now - just like new. IF I see pumping again after a few hundred hours, I'll know what to try anyway.

FWIW, mine was pumping from day one including after several firmware updates. Only after I did the on/off reset did the pumping stop. What I don't understand is why no one at Sim seemed to know about this since they were aware of pumping complaints for several months?

Mine has been good since the ON/OFF trick.

Mine was not pumping at all, many months after purchase, until recently.

Same here.

Later today, I am planning to do a firmware update on my non host lumis.

This will be my first firmware update and I am a little apprehensive.

Will I lose any settings, do I need to back up anything before following the sim update instructions. Will my calibration be affected?

Thanks

Sorry to say, but with the firmwareupdate you will loose all your settings and calibrations, you cannot store it; you have to note it;

on the other way I would recommend a new calibration. Firmwareupdate will also affect the videoprocessing. Settings based on the older firmware are often not okay with the new firmware

But doing the settings and the calibration new with the LUMIS running on the latest firmware, you will win in a better picture

Previous firmware updates did not cause settings to be lost. Is this something new?

Must be new... or the poster is mistaken.
