After all these years!

Getting an issue while manually calibrating the Samsung UN65HU9000 Greyscale and CMS
(and previously the LG 55LHX, and the Samsung PN64F8500), I got that `Does not
Respond to setting changes' moments!
Will shut everything down, and start over, to continue to finish, or sometimes come
up with the same stalemate. But results were always mixed.
Also over the years was the Info screen popping up from the Radiances due to some
conflict with the TV Remote.
Pushing the Exit button got rid of that issue.
Last night, it finally dawned on me. The Radiance was also being affected in other ways
by the TV Remote, but because nothing was seen on screen, never thought my calibration
was being compromised!
So, last night I covered the front of the Radiance to prevent stray TV Remote signals.
Absolutely the BEST calibration I've done in years!
No more cursing the TV, Calman, and what ever! Radiance front stays covered through out
the calibrations from now on. Only signals going to it is the Serial Connection.

Addendum:
Turn Off the Radiance IR: MENU 0995. To turn back on repeat, or remove power Input, wait 10 seconds and reinsert.

Selling my Radiance XD

If anyone is interested, I just listed my Radiance XD on Ebay.
I hope posting this on AVS is not against the forum rules.
Thank you guys!

Does anyone know if, ever, my RadianceXD will be able to pass a signal with proper chroma upsampling?

The Radiance does do proper Chroma upsampling. If you are referring to some test patterns that use out-of-band Chroma, as discussed else where, these patterns create situations that do not reflect real video when being processed/scaled. The patterns can be useful but you need to be aware of this.

The GF9450 deinterlacer has a very slight loss of Chroma bandwidth, but this should not be visible on actual video.

I'm referring to test patterns on the Spears & Munsil test Blu-ray. I've tried on both my Oppo BDP-103 and the old 83, before I sold it.

That is what I expected. These patterns are useful, but they create out-of-range values when converted to RGB, which are clamped (which cause changes in the waveform when processed), and since they are hard edge toggles (i.e. max-min-max-min) a Chroma filter will not work correctly since this is effectively "out-of-band."

No real video source would create either out-of-range RGB or out-of-band Chroma signals when properly processed and so the test pattern is not good to judge electronics that are processing the image. They are fine for seeing how you TV reacts to such a signal, but you need to understand the above discussion to make any judgments.

Don (Munsil) and I discussed the pro's and con's of this in a different thread (or maybe earlier in this thread. I don't recall exactly where).

At Lumagen, we did take the time to change the Radiance FPGA design to make this pattern look as good as possible, but found that the GF9450 chip did not pass it perfectly and there was nothing we could do to get the GF9450 to look better for this test pattern. BTW: You can bypass the GF9450 in the Radiance for progressive sources by selecting "Game Mode." This will improve this test pattern.

In my considered opinion, you are better off using a quality Blueray movie to judge Chroma bandwidth for real sources.

Is there a specific movie and scene you can recommend? I'm not very experienced with this, so I think you'll have to explain to me exactly what I'm looking for.

Good question. Unfortunately I don't have a specific recommendation to give you.

You might look for a a scene with cloth that has saturated colors in a pattern that creates high frequency changes in color as opposed to only Luma.

Evaluation of actual video is much more difficult then using a test pattern. The biggest issue is knowing how much detail is actually contained in the source and how close to ideal the display is reproducing the material. Also, there tends to be high frequency Luma changes where there is high-frequency Chroma. This actually helps the image as the high frequency Luma compensates to some degree for having less resolution in Chroma.

Chroma is compressed a lot more than Luma in real material. First there is the fact that consumer video is encoded as 4:2:0 (i.e. 1/4 resolution for Chroma), and the "DCT truncation matrix" and other compression algorithms are much more aggressive at throwing out high-frequency Chroma than they are high-frequency Luma. All this complicates the task of evaluating Chroma further.

Test patterns exploit some special encoding that would not happen in real material and so they can have higher frequencies than is normal in encoded video. This makes them useful especially if they follow the Nyquist sampling rules used for video. On-off patterns can be useful as well, if evaluated knowing how they affect video filters.
