We have been working with Lumagen on the Radiance boxes (the Mini specifically) as we have integrated it with LightSpace CMS.

We found a few issue with the boxes that had been missed by other calibration partners, and Lumagen are looking at fixes, including a peak luminance issue.
We also found we had to use PASSBACK OUTPUT 1 to get the correct EDID data communication.

So, it looks as if this is the correct configuration for some set-ups.

There was a very small error in the peak luminance value, if the Radiance was set to "RGB PC level input" and "RGB PC level output". It is unlikely that a system would use this input and output format for video.

We continue to recommend that you set your video source output format to YCbCr 422, if this format is available. We also recommend setting the output of the Radiance to YCbCr 422, if your display supports this format.

Went back to an older version of the Mini 3D firmware, and the 3D works correctly from the Micca, as does bypassing the Mini 3D. Just with the Micca player mind you, my Sony Blu Ray player still passes 3D correctly.
If I recall correctly, there had been bug fixes in the past for certain 3D or handshake issues, so curious if anyone has a Micca and a Lumagen and can test, or if anyone is having issues passing frame-packed 3D through the Mini with the latest firmware.
I see this feature listed above:
Could there be some setting in the Mini which is converting the frame packed signal incorrectly in certain cases?

I have the Radiance XS. The 1026 firmware breaks 3D playback. The left and right eye images are swapped. I had to flip my 3D glasses upside down to view the picture (obviously not a viable solution). Rolling back to 1017 fixed that problem. I reported this to Lumagen, and they're looking into it.

[Correction: Apparently it was a now-deleted 1025 firmware that broke 3D playback. The current 1026 firmware is supposed to fix it. I haven't had a chance to try that yet, though.]

I have two source devices (Netgear Neo TV550 and Moxi DVR) that are sending YCbCr 444, but there is no way to specify the output format in the devices. In the Radiance HDMI Input Setup menu, the HDMI video type is set to Auto (changing it to YCbCr 422 results in purple-ish colors), and the EDID is default. Shoud I create a User defined EDID to "force" the source devices to send YCbCr 422? This assumes they will read the EDID from the Lumagen.

Thanks.

Press the "Ok" button on the Lumagen remote to display the Radiance Info Screen. This shows the color format on the input and output of the Radiance.

I guess I did not articulate the situation correctly: The input from both source devices is YCbCr444, and the Radiance is sending out YCbCr422. I was just wondering if I should try and force (via the User Defined EDID) the source devices to send YCbCr422 to the Radiance.

Thanks.

I think the answer is 'yes', if you can.

We recommend setting your video sources, if possible, to output YCbCr 422 and the native resolution of the video.

You should use HDMI cables that are at least 2 meters (6 feet) long. It is best to use good quality generic cables that are equivalent to cables from MonoPrice.com, Bluejeanscable.com, or PCHCables.com. We have received reports that some of the high end cables have caused problems in some systems.

I'm in the UK and have a Humax PVR that outputs at 1080/50i and YCbCr444. I just went into the EDID settings and I already had my Mini3D set to 'NO' for 444 and 'Yes' for 422, yet my Humax must ignore this as it still outputs at 444. I've reset it to 'Yes' as sometimes it takes a while for the image to appear on my TV so perhaps this was why (I must have made this change ages ago)? If anyone does try this and finds that they still get 444, then don't forget to go back into the Lumagen's settings and put it back to 'Yes'. smile.gif

Is there a way to do a VARIABLE amount of NLS with the RadMini?    I.e., my screen is a 2.0 AR (144x72).     When viewing HDTV with the pj zoomed to fill the 72" height, the 16x9 pic is 128" wide, and it might be nice to do NLS to fill out the 144" available width.     

 

Is there a way to do this?

You can zoom out your projector so that it fills the width of your 2.0 screen. Part of the 16:9 image will lap over the top and the bottom of the screen. You can follow the procedure in "Tech Tip 16" to set this up. The only difference is that you would enter "2.00" for your output aspect ratio and use smaller "Output Shrink" settings.

You could stretch a 16:9 image to fill your 2.0 screen by pressing "16:9" then "NLS".

Thanks much, Randy; I'll mull over this.      In the first approach, it sounds like I would be loosing more brightness than in the second; is that correct?

Using the "NLS" function to stretch a 16:9 image to fill the entire 2.0 screen uses more pixels on your projector, so technically it would be brighter. In reality I don't think that you would notice much, if any, difference in brightness.

By using more pixels it would presumably then (at least technically) be a better pic, right?

 

Since I'm such a Radiance novice, would you mind sending me a pm* (so as not to clutter up the thread) on precisely how, and where, to do this?    Many thanks.

 

*or email (millerwh@berkeley.edu).

This is Jim Peterson. Allow me to answer this for you.

NLS distorts the picture to fill the screen. Whether this looks "better" or not is subject to personal taste. I personally prefer the image with black bars to view as produced. Others prefer to fill the screen with a linear zoom in (you lose 16% top and 16% bottom). Still others prefer to use NLS with a slight top/bottom crop to mitigate the distortion introduced with NLS.

If you allow some of the image top and bottom to be cropped to minimize the distortion, NLS 16:9 to 2.35 can look very good. As discussed before the Radiance allows you to adjust top/bottom crop, center width and center stretch so you can optimize the image for your taste.

Jim or Randy,

My RS55 is fed by my Pio SC-07, which is fed by my Radiance XE3D (which I use to switch sources). I also have a 2.37:1 screen with an anamorphic lens which I leave in the light path at all times. On all of my sources (BDP-93, XBox360, and Verizon FiOS cable box), all of the images are slightly underscaled in the horizontal direction regardless of which scaling mode is selected. As an example, in both 16:9 or LBOX mode, I have 2" wide black bars on either side of the image; when watching a 16:9 movie, and I select the 4:3 scaling mode and set my motorized masks to 16:9 mode, I still get the 2" wide black bars. This does not happen with the Radiance out of the video chain, and it didn't happen when I had previous JVC projectors (RS50, RS35, and RS2) hooked up to the Radiance.

I'm suspecting that this may have something to do with how the e-shift scaling on the JVC is interacting with the signal output from the Radiance, and I've combed through all of my settings in the Radiance and can't find anything that would cause the black bars to appear. Do you have any suggestions for things that I can check?

As an aside I just got my Radiance back from you guys for some service, and I will continue to echo previous comments that I've made about Lumagen's responsiveness and customer service overall: exceptional, outstanding, peerless...I think you get the picture. Your products - and the constant updates and service that comes with them - are worth every penny! Keep up the good work...

You don't have masking turned on in the JVC RS55 by accident? I have the RS55 and XE3D, but don't have a anamorphic/2.35 screen setup. With my 16:9 screen it never does what you are describing. SJ

Nope, with the Radiance out of the video chain, the black bars disappear..

Have you got the masking enabled in the Radiance? I can't remember the exact menu right now, but it is possible to mask the sides by any percentage.

HDMI transmitters and receivers have cable EQ. Most chips use a static EQ, which has to be optimized for a specific range of cable lengths. From experience this seems to be in the 15 to 25 foot range for the center of the curve. Typically this means cables in the 6 foot to 45 feet range work at 1080p60.

We have had a number of systems that were experiencing cable issue start working when a 3 foot HDMI cable was replaced by a 6 foot HDMI cable, and even a few that started working properly when a 6 foot HDMI cable was replaced by a 10 or 15 foot cable.

Please note this is not specific to Lumagen. It is a common feature of HDMI transmitters and receivers.

In factory default state SD is assumed to be 4:3 and if you output it at an HD rate, you would have side bards (pillar box). you can change this by selecting the input aspect ratio. For HD in and out the input is initially set for 16:9 and so is the output. SO for HD in and out it will not produce side-bars unless some settings have been changed.

Press OK and then OK again to see the Radiance info screen that shows what the Radiance is getting for input and sending for output resolution.

You can temporarily go to a factory default state with Menu 0999 to see if the setting at causing what you are seeing. If you do not do a Save you can get back by going to STBY and back on.

Help needed. Its winter so now time to figure out what I'm doing wrong with radiance xd. My Pioneer elite 151 with radiance xd using calman 4 and ef-1000 meter never gave me "wow" factor I was looking for. I need more "pop" to the pic if possible. Was thinking of getting calman 5 bundle with i1D3. Is there some settings in xd I can manually tweak for better punch? (I have ISF unlocked and controlcal available) . Maybe Darbee (dont shoot me...just asking smile.gif )?

Strongly suggest a complete Standard Calibration, then add in the Darbee. (And you'd better get it quick because the price is going back up!)
Myself, I Calibrate with the Darbee Inline. Found I can now run the Darbee at HD 65% after calibration with it inline during calibration. (55% Max before) (Also Darbee and Radiance do get along.)

What is the current status of XE and 4K? Will this be a board swap? or FW upgrade?

For those who have worked with both the iScan Duo and the XE, does the Radiance have better Brightness/Contrast Patterns? Found I had to use the AVS HD 709 Blu-ray for these instead of the iScan Duo's.
