Dave -

I think you have a typo for XE -- should be 111509

Thanks for the updates and testing...

Believe what you like, but if the i1-Pro and Chroma 5 were good enough, nobody would use more expensive instruments.

I've gotten outstanding results using my i1 Pro. I simply could not justify using anything more expensive for my cinema.

The whole point of the Radiance is to make images just about "perfect" in regards to grayscale, gamma, and color. To spend $4000-$6000 on a Radiance and not use an instrument "worthy" of the Radiance's performance capabilities seems... odd. If you're on a severe budget... you do what you can. But most people willing to shell out the cost of a Radiance aren't exactly scraping the bottom of the barrel and paying for professional calibration employing an instrument that's equal to the Radiance's performance/adjustment capabilities is really the whole point of the Radiance. Part of the "Radiance experience" is KNOWING you can't make the picture any better -- it takes a meter of very high performance capabilities to achieve that level of confidence (mostly for color, though, the C5 and i1Pro are ok for grayscale).

I really like all of the FW updates for new features and bug fixes.
I was wondering when the Radiance manuals get updated to help figure out how to use all of this new stuff.

The online manual is from 072009.

We are working on an update. Should have soemthin on our website in the next week or so.

A question asked earlier was: Does Game mode bypass the Gennum (now Sigma) GF9450?

Didn't see an answer so here it is:

Yes, the new Radiance game mode does bypass the GF9450. We choose this to minimize latency. So, the GF9450 enhancements are not available in game mode.

Note: Game mode is not intended for (EDIT) interlaced video program material, such as TV shows. You can, of course, use game mode for games with interlaced output modes. Since the GF9450's diagonal deinterlacing is not available in game mode, using the Auto or Video-only deinterlacing mode for interlaced TV program material will provide better results.

Note: Turning on Genlock will minimize the total latency (and provide a constant latency) since the input and output always have the same input-to-output frame phase relationship. Normal Genlock restart delay applies. So if you have a game that switches between 480i and 240p you might want to leave genlock off to avoid the few second time of video mute needed to relock the genlock during the input resolution switch.

The Film mode also bypasses the Genum, so does that reduce latency over the auto/video modes? Is the latency similar to game mode?

Thanks.
Lot's of great updates since the manual was last updated.
It would be just good to see a little more explicit "manual-like" details to help us Radiance newbies.

I never made an arguement that $4-$6K on a Radiance justifies $10K on a meter... you did that all by yourself. I was suggesting that paying a calibrator with a $10K+ meter to make sure things are "right" (and that implied that you could then measure with your meter and note any "offsets" so you can re-tune in the future). Your own argument seems... odd at best. If you weren't into having the best possible picture (so you could forget about it) you wouldn't HAVE a Radiance - which puts you squarely in my "Radiance experience" definition whether you like it or not.

Once again, the whole point of the Radiance is to make the picture as perfect as it can be... so you CAN forget about all the tech and enjoy the picture. Being able to forget about all the tech is the whole point of "the Radiance experience". The C5 and i1Pro both have limitations - different limitations for each. And those limitations are primarily in the accuracy of color measurements - the limitations are well documented and don't need any further characterization by me. I never characterized either the C5 or i1Pro as providing terrible results - you did that yourself. My "characterization" merely implied that they would not provide the same result as a meter with good color measurement capabilities (and those are never inexpensive meters). And that also means that the Radiance is capable of providing better results if it is used with a meter that is as good/accurate as the Radiance can be. There isn't anything heretical or hateful in that statement - it is merely accurate.

For Film-only mode, we need to do cadence detection. The latency for film-only mode is effectively the same as "Auto" and "Video-only" modes.

So, game mode has a shorter latency than any of these other modes.

i have been following this thread for a while, it seems like there are very regular firmware updates for the XD and the XE, which is fantastic.
however do the firmware updates wipe the settings and are there any firmware updates that once the update is done i would have to calibrate again?

my ideal would be to have the radiance, hire a calibrator and then leave it except for the annual or so touch up, however i like the idea of constant bug fixes and improvements, can i have both, a set-it-and-forget-it with constant updates?

The settings are almost always preserved on applying new firmware. Lumagen would let us know if they weren't. To be honest, I think the development cycle has reached the point where preserving settings is mandatory.

Great, thank you guys both very much!

the firmware question was my last sticking point. I went ahead and ordered a radianceXS from sencore.
i previously had a dvdo edge, i got my radiance this week and have been going through the set-up. havent gotten through nearly all the settings yet, but i am very impressed so far, both with the product and the customer service from Jim at Lumagen and from everyone I have spoken with at Sencore.

to me it is a noticeable upgrade (at the price it should be)
thanks everyone for their help

I am watching this with great interest...

Hi,the chip Gennum 9450 support in the future 4k resolution??
IF no,it's possibile an hardware upgrade?
Thanks

The current HDMI specs (v1.4) do indeed include 4k resolutions:
http://www.hdmi.org/manufacturer/hdmi_1_4/4K.aspx

Given what Lumagen has hinted at in the past, it would not make sense to include 4K support on the Radiance XE....although it may make sense on an XE PRO with HD-SDI (as well).

This is why I suggested that it would make sense on a Radiance XE PRO, and not an XE/XD. I also believe, as your suggestions prove, that a 1080p customer and 4K customer are completely different customers. I am willing to bet that a very small percentage of 4K customers will ever post on a forum, as their systems where spec'd/installed by a high-end installer. Another thing to consider is 4K content, but that is where No Ring scaling would be incredibly beneficial with all the existing content.
