Curious how a 20 pt dE measures with the 90 contrast settings.

What type of patterns are you using? Window, APL and at which size or percentage brightness?
I've never been one to experiment with many test patterns (and I probably SHOULD). I used 10% APL windows from the GCD disc.

It was getting late and sleep (and calibration time) is scarce with a toddler in the house so I didn't run it. But I find I usually do well in 20pt unless ten point adjustments are large.

Only error spikes were in near white around 96-98 and they were still in the 2.0 range. Everything else was below 2.0 and mostly at or below 1.0.

I tried all of this because I was getting strange results at 90 IRE. Having ten point adjustments available I'd set two point with 30 and 100 but 90 always needed massive adjustments. This approach seemed to avoid that.

So many variables; iirc, I used 20/80 for my 2 pts. Good to see someone else chase those rabbits. Thanks.

Also note that Cinema Smooth is on. Turning it off changes the readings quite a bit.

This is not our main TV(I've only put about 500 hours on it in a year) and I pretty much only use it for 24p movies. I've experimented with all the available motion settings (including letting the bluray player do the pull down etc) and Cinema Smooth seems to be the best of what I consider bad options. It just adds a little flicker in bright scenes. I get a more 'stable' calibration in the 60hz modes but the pull down visible annoys the hell out of me and the Motion Judder Canceller even on low is way too smooth for me and introduces a ton of artifacts (although it DOES bring out a lot of motion detail). I've only recently owned plasmas and I'm actually disappointed in how they handle 24p motion considering how motion is supposed to be a strength.

My guess is that eco mode just uses the cell light register internally at courser steps so that peak white will start dropping at the sample APL level in either case. I haven't done the measurements to verify but I'll take a look at some point.
I checked this tonite and ABL behavior is also identical, the roll-off in peak white vs. APL is exactly the same in eco mode "low" as setting cell light to 14. I checked at two different settings of cell 20 peak white via contrast.

cool, thanks. power of suggestion i guess. my mind saw what it wanted to see... that's why i love science! can't trick the sensor.

i think the problem is that 24p video is terrible to begin with. with the S&M disc, the only time i saw 'perfect' motion was with 60fps source.

like you said, best of the bad options. this is why i hope HFR doesn't become lost in the 4k, hdr, wcg craze. seeing the difference between 24fps, 30fps, and 60fps motion on the f8500, to me it's the biggest improvement of the bunch.

I suppose I also like the subtle smoothness you get on LCD derived tech that does black frame insertion or backlight strobing well at 120hz and wish the F8500 had a setting that mimics that look. Of course LCD has other issues.

That and if you're below 100 cd/m^2 peak white where I was testing this, the ABL doesn't kick in until around 75-80% APL, so you'd be hard pressed to find real scenes to even compare the two settings visually.

with 'low frame rate' material, I also find my lcd give perhaps more pleasing motion. but it's because it has WAY better software for the frame interpolation. while the f8500 has settings for off, too high, and WAY too high, the lcd also comes with individual controls for de-judder and (I can never remember the name of the second control) and each are adjustable from 1-10. I've noticed that the de-judder starts giving me SOE at a setting of around 2-3, but the other control can be pretty much cranked without too much issue. I believe I have them set at 1 and 7, and find they make all content look pretty close to 60fps content.


it is a shame that they did not bother to give the f8500 any USEFUL frame interpolation settings. it's definitely not a limitation of the hardware

that could be the case too. I believe it was around 30-32ftl when I had eco set to low.

Cinema smooth question

Hi, I'm still pretty confused about the cinema smooth setting on the tv.
When I have it turned off there's some frame skipping every few minutes when playing blu rays, when it's turned on it doesn't seem to skip anymore but it does have a slight soap opera effect (motion judder is grayed out and it shows off)

Is there a consensus on the best option for blu ray watching? What is the closest to the way blu ray original content is supposed to look like?

My blu ray player is a samsung as well and it seems like it doesn't have the option of 4:2:2 color space only 4:4:4 which is what I have selected.

Also, can someone please explain to me what the hz settings are and what is the best option for blu ray playback. What settings should I have on my blu ray player and tv so that, together, they show me movies how they were intended to be seen, or as close to that as possible.

Thanks in advance!

use 24hz on the blu ray player and turn the TV to cinema smooth.

I started to wonder if there was discoloration near peak white that I wasn't seeing by eye. I was always able to get things to line up pretty well with two point white balance only other than IRE 90 and 100. So I decided to test a theory....I ran a calibration at 90 contrast to see if I could avoid using the ten point controls almost entirely ('almost' because I would certainly need them at the low end for BT.1186).


It turned out that this approach worked for the most part and the controls lined up better than I remembered (Or maybe I'm just getting more experience).


Anyways I really like the results. I haven't watched a lot of content yet but the picture seems more 'natural' to me.


Attached are my current settings. I have a 51 inch panel.
With that approach, you could probably go even lower on contrast - in the mid/low 80s and have a higher cell light.

I suppose I'd be worried about the ten point controls being misaligned to the point where adjusting them WOULD finally be annoying at much lower contrast. But if the reports of ABL behavior being tamed at higher cell lights are correct there could be some benefit. As of now I really don't see ABL clamping down so I'm not the best person to confirm that.

Try increasing backlight to 15 and keep all other settings unchanged.
