Official Lumagen RadianceMini 3D thread. - Page 27

hrc4u:

The chips do connect to the case but through the PCB, and its power plane layers. The case does act as a heatsink both for heat conducted through the PCB, and for heat radiated from the chips to the 16 gauge steel top cover.

Adding heatsinks is not a bad idea nor is adding a fan. However, these should not be needed since the Mini is designed for convection cooling. Just make sure to have good ventilation around the Mini.

To my delight, the dropouts have now dissapeared after following your advice. I changed my 0.7m cable between Mini3D and Darbee and the dropouts are gone..thanks for the tip;)

Great it worked out ok!

Hi Jim,

Don't have a Mini but my experience with a Dune HD1 is that with a smaller metallic casing (such as your Mini), it is vital that the ventilation slots to remove heat (and allow cool air in) via convection are adequate.

Fans seem to only circulate heat and heatsinks have a delaying effect on heat build up if ventilation slots are inadequate.

With my Dune, I had to literally convert my cosmetic louvred slots into something resembling a fully pierced slot.
The result was that a very hot to the touch metallic casing became a barely warm media streamer, without the need for fan or heatsink addition.

Apologies if this is not an issue with your product but Dune don't understand that ventilation means having a cold air input as well as hot air exit for any heat or ventilation problems.
Otherwise relying on radiation from the metal case may not be sufficient.

Gonna get a Mini soon. Question, I know you need to break-in a TV before calibration. What about the Mini? Is there a recommended break-in period before calibration? FYI - I'll be using Calman5 and my i1 Display Pro.

No break in needed on the mini, just plug it in and get started!

Hello,
Finally my Mini arrived yesterday.
Many thanks to Jim and Dave for their fantastic support...the best on the market.
My prime source for movies is my Dune Base 3.0.The input in Mini 3D is YCbCr4:4:4.,from Lumagen to my JVC HD750 i selected the output YCbCr4:2:2( default was RGB)
My JVC is on HDMI standard with contrast,brightness ans sharpness all set to 0.
I made a quick correction for white level at 100%,after that i am ready for Adv Auto Cal from Chromapure.
I choose from Lumagen 75% intensity and greyscale and gamma in 11 points,after that i am good to go?
There is something else that i should look, to optimize my calibration?
Thanks

Did you check black level?
It's a good idea to measure greyscale and gamma and probably set 100% white point accurately using projector controls as well as putting gamma to closest setting to correct. If gamma is not linear i would suggest using the setting that puts the low end closest to correct and let the auto cal fix the higher luminance levels.

Hello,

After two attempts i got mixed results,probably it's all how i prepare my JVC for auto calibration.
My JVC is on HDMI Enhanced with Contrast:+12 Brightness:-7 Colors;0 Sharpness:0. Mode :User1 6500K gamma:2.3,Color Space:auto
I made a correction on white level at 100%.
Today i will make another attempt.
There is another preset closer to ideal from JVC and give an better start to Lumagen?

Thanks

Hello,
If I performed an auto cal with Lumagen and Chromapure on MEMA from my Mini 3D,how I can perform a new calibration on MEMB without erase the previous one?For example on MEMA I have Gamma from auto cal on B.T.1886 and I want to try a new one on Gamma 2.22.
On MEMA I have custom,cms,style on 0 and if I set MEMB I have the same.
Thanks

In brief:

You need to set up MemB so that it uses another CMS. I prefer to be logical with my CMS, Style and Mem settings so I follow this order:

MemA: CMS0, Style0 (Main TV)
MemB: CMS1, Style1 (My Projector for use with my A Lens some cropping required due to overscan)
MemC: CMS2, Style2 (Projector for use without my A Lens, different cropping required)
MemD: CMS3, Style0 (Second TV 1080i input only)

In your case you may only need to change the CMS for each Memory slot. You do this my going into the menu>output>output setup> then set up which mode, CMS and style you require for 2D and 3D.

Before you start the autocal you need to select MemB with a different CMS# otherwise as you say it will overwrite your MemA CMS (or which ever CMS is currently in use). As a backup you can use the copy function to make a copy of your existing CMS into a spare slot (ie copy CMS0 to CMS5). You can also backup the configuration (using the Lumagen config tool) onto your laptop which is probably a good idea since autocal does not ask you to save changes: It will do it automatically at the end of the calibration.

Thanks, Kelvin
In this moment my gamma and greyscale are as good as can be,I use MEMA with Custom0,CMS0,Style0 and i want to give another try to Auto cal for 125pt.
On MEMB i want to have the same gamma and greyscale,but i want to give a try to auto cal for a different Advance CM for 125pt.
What i have to do,to be sure i will not over write the actual 125pt color management?

Copy CMS0 to CMS1 and asign CMS1 to your MemB output (for all resolutions). Then select MemB. Uncheck the autocal greyscale option and just do the advanced colour calibration. This will then overwrite only the colour gamut settings in CMS1. Not sure what you hope to achieve by this unless you've changed a target setting (like SMPTE-C instead of rec709 perhaps) but it will do what I think you're asking.

ok...some additionally cooling added to hotspots...should do it....sand lapped heatsinks glued with thermal addesive arctic silver compound
(yeah i hate hot electricks )

Nice! I'm using a Notepal U1. Does the trick nicely. Just the right size, made out of aluminum, the fan can be positioned anywhere, and the holes align on the money with the mini. I added little rubber feet to the mini also. My mini stays nice and cool.

Here's the U1: http://www.coolermaster.com/product.php?product_id=6611

Does the mini have a heating problem, or did you do this just in case?

No it does not have a heating problem. If it had a hearing problem i think you'd find lots of posts from folk saying they were overheating everywhere, but you don't. Obviously it would be foolish to place the unit on top of a receiver in an enclosed unit but i'd assume most people realise that's not a smart thing to do....

Sv: Official Lumagen RadianceMini 3D thread.

No direct heat problems...did it just in case..and to keep the chipset moore cool..the biggest where running little over 50c...

Nice! :-) i just put a small fan blowing over/under the mini also to keep some airflow around it :-)

Hi,

found this in the calibration thread:
http://www.avsforum.com/t/1461363/ee-colorbox-lightspace-and-3d-lut-calibration/30#post_23053470

after reading all comments I watched out for the distortion issue on my Mini 3D and it seems to be true. Did not notice before as I never watched out for such kind of issue and trusted the Mini to have clean signal processing / passing.
Looks like a black level shift, but with all processing and conversions etc. turned off??
When connecting the BD player direct to the TV the image looks more detailed in dark areas.
BD Players and Radiance output is set to 4:2:2 as per recommendation.
(Firmware 103012)

Can anyone else confirm or deny ?

The Radiance default in to out is accurate, but levels can change by a LSB or two. Use the Radiance dark contrast to set black level, and you should see the detail come back.

Can you tell me, what you mean with LSB. English is not my native language so some abbreviations are a little difficult for me.

I know LSB only as least significant bit and this could never be two.

I've check my black level setting before posting here. It seems to be perfect with different pattern including the contrast2 of the Radiance.
If I raise the black level by only one click, video level 16 will highlight, picture looks washed out but distortions stay and do not change.
Think if it would be that easy the 2 guys in the calibration thread did not mention. Both seems to be very smart and have much experience in calibration. Myself, I have experience for about 2 years now, and black level shift is something very basic You learn right at the beginning.

Apparently must be something different than black level shift...

Illusion can be a powerful thing when posts are worded to give the appearance of authority and experience. One of those guys have been calibrating for not quite a year. So don't regulate yourself to the backseat with 2 years of experience.

true words... and be sure I will not lean back as I'm far away from my personal goal.
But maybe You have some advice on this issue?

I have the exact same issue you described. Bought my Lumagen refurb from AVS and it drops the video to blank green/purple/black screen after a few minutes. Tried all the same stuff you did, changed cables/inputs on the mini etc. nothing works with the Lumagen in the chain for more than a few minutes.

I just contacted their support line via e-mail, hope it can be resolved just like yours because for the few minutes it works before dropping the signal it's great...

Super impressed by Lumagen's customer service...noted the issue I was having regarding the video drop-outs and within 24 hours they already followed up, identified the issue, and offered to repair it via mail-in. Even offered to pay for return shipping.

Little stuff like that matters...would make me real comfortable buying from them in the future and recommending the product to others.

Yes, Jim and Randy really are old school, in a most positive way...

I've had nothing but great support and follow-through from Lumagen...

Hi, I noticed there's an update for the mini to adress among things the YCbCr output issue. What issue is being fixed, and does it mean I need to recalibrate after updating?

No need to recalibrate. There was a minor conversion precision issue with YCbCr output modes that did not affect calibration that is corrected by this release.
