Samsung PN**B450 Picture Settings - Page 41

I haven't tried it but I have opened mine up to try and get rid of a diffusion problem but that's it.

Greetings,

Herein are settings adjusted for the lowest possible black level. Instead of focusing on rgb levels, I adjusted the brightness setting where the gamma curve will come up above 2.2 on the graph. Then I lowered contrast to where the "17" level on avs 709's brightness pattern was flashing, and reduced the gamma setting in the advanced options to -3 to get a dark picture. Took about 2 hours total.

For DYI calibrators, measured gamma is 2.33, peak white @ 100 ire is 32.5, and static contrast ratio is 765. See gamma, temperature, and rgb graphs below. Please note that I am still working on sharpness setting, just got tired.

Greetings once again colleagues:

I have attempted to readjust the black levels again. This time I set brightness to 53, then adjusted contrast level to where the #17 is flashing on the avs 709 brightness pattern. Next, I jacked up the gains to their highest consistent levels to level out the gamma graph. Picture looks great, even without edge enhancement. RGB levels are inconsistent around 60 ire.

DIY calibrators: Average gamma 2.34, static contrast 1007, peak white @ 100 ire 40.194.

Greetings Colleagues,

I have tweaked the component settings above by adjusting the green gain, which apparently had a great impact on the settings. Average gamma increased to 2.36, static contrast went up to 1366:1, peak white to 42.9, and 0 ire measured to its lowest at 0.031 ftl. Picture actually looks better with edge enhancement off.

For your convenience, I have attached the gamma graph.

Comments: Brightness 53 appears to be the best level to have a flat gamma curve. I tried brightness settings for 52 and 54, but the gamma curve always had a "bump" in it. Also, the cell light setting affects gamma, with setting 7 appearing to be the best setting for the flattest gamma curve. The gamma setting in the advanced settings was set to -3 to increase average measured calibrated gamma around 2.35, which is recommended by some forum members for hdtv's. The white balance gain setting for green was increased to stabilize rgb levels. Also increasing the gains for red, green, and blue helped to decrease and flatten out the gamma curve above 70 ire. Still use pop sharpness technique, which is easier when you have a peak white level around 40 ftl, and I consistently obtain a 10 or 11 setting.

As always,

It's great that you are still providing updated settings for this set vincent. Tried out the settings before you made tweaks early this morning, so I'll have to make sure I have the most current ones.

Please keep in mind that all electronic devices may be different, even if they are the same model number. The posted settings should nonetheless put you in the ball park for component settings for a great picture. I focussed on darker settings to avoid the temptation of adjusting the voltage trim pots to possibly get darker blacks.

Please let me know how your picture looks.

As always,

Yes, thanks for doing all the "heavy lifting" on this and posting your results.

CruelInventions,

Calibration is just a hobby that I usually do a few times a week. Not really heavy lifting, but just a break from the wife and kids.

Below are my updated hdmi settings, with a slighly dimmer picture which doesn't hurt the eyes as much: peak white 33.8, average gamma 2.32, and static contrast 850:1. Also, gamma curve graph and rgb levels posted below. The major change was brightness from 53 to 54. Notice the "bump" in the gamma curve.

Keys to calibration: peak white level increased by increasing the rgb gains, static contrast ratio may have increased
by lowering the rgb offsets or cuts, it appeared that the gain for green had an impact on rgb level stabilization, and cell setting impacted gamma curve. it took a lot of going back and forth to find best cell, brightness and contrast levels for consistent colors, flat gamma levels, etc.

Probably the only thing left to do is to calibrate movie mode/warm 2 with a flat gamma curve close to 2.4. This may require a small service menu adjustment for sub gamma to M1 or M2, which I believe translate to minus 1 and minus 2, with adjustment to the gamma setting in the user menu, to get the average measured gamma to 2.4. I will try this down the road and probably post it.

per posts in this forum, the higher the average gamma level, the more vivid the colors.

March 8, 2012: If anybody is interested in updated movie mode/warm2 settings for gamma @ 2.4, please let me know. It does not appear to require a service menu adjustment.

Hello, Vincent, thank you for the calibration settings, I applied them to a couple of family tvs and wow, they are very nice!!!
Since you offered it would be very kind of you to post whatever you can for Movie mode as this is actually my favorite mode.
Thanks again for keeping this nice tvs ticking with your research and settings.
Greatly appreciated.!!

Greetings Colleagues,

See "evolving sharpness" settings below if your cable signal is set to 1080i.

Updated the component settings for both movie and standard modes using the ganging method of equally increasing rgb levels after calibrating proper rgb levels, per comment in this forum. This allows for flattened gamma curves. Movie mode can be tweaked a little in the service menu to increase range of red and blue gains, but not necessary. The gamma graphs for both modes and rgb graph for movie mode below:

Greetings,

Please note the sharpness setting changes for latest updated standard and movie modes for both hdmi and component settings. I checked the settings this morning for only sharpness and found that they were slightly off. I think that, after hours of calibrating rgb levels during the evening, my eyes were too "tired" to accurately calibrate sharpness.

These are tricks of the DIY trade calibrations.

As always,

Vincentfam

Please note that the sharpness settings above have changed and these new settings look better. I am still using the pop sharpness calibration technique and trying not to squint, and I discovered one important thing:

I may need new glasses.

Edit: Additional sharpness changes using avs forum 709 disk.

As always,

Vincentfam

Greetings,

March 23, 2012 Updated

See "evolving sharpness" settings below if your cable signal is set to 1080i.

My recommendations for sharpness settings for the above recent calibrations are to use the DVE sharpness pattern and increase the sharpness settings from 0 until you start seeing (from where you are sitting) artifacts on the "outer part" of the large circle. Then adjust or decrease the settings when the artifacts appear to almost disappear, usually decreasing the sharpness setting by 1 point. This should give the picture a good crisp appearance.

See my post on pop sharpness settings:http://www.avsforum.com/avs-vb/showthread.php?t=1388270 (view this link for techniques only and ignore the settings in that link that were based on different calibration adjustments)

March 18 Edit Had to adjust the below recommendations. Blu ray was set at 1080i instead of the recommended 720p for calibration; and used "normal viewing" instead of squinting.

41 is the recommendation for movie component settings. 35 is the recommendation for movie hdmi settings. 2 is the recommendation for the standard mode for component and and 4 for standard hdmi settings.

Hope this helps. I do not anticipate any more sharpness changes.

As always,

Vincentfam

Sharpness settings updated due to wrong blu ray setting. See above.

Greetings once again Colleagues,

March 23, 2012 Updated

See "evolving sharpness" settings below if your cable signal is set to 1080i.

I just thought I would post some explanation regarding sharpness, which is probably one of the most important yet difficult settings to do.

In using the pop sharpness technique, you want to adjust sharpness to where the artifacts just disappear on the outer circle of the DVE 720p pattern. This is easier to do for the standard mode because of the higher contrast and peak white level. That is why I consistently obtain a setting of 5 for hdmi and component settings.

Setting sharpness for the movie mode is a little more difficult because of a darker picture. The artifacts are difficult to see when they first start appearing. With practice, I have narrowed the movie mode settings for sharpness (no artifacts on the outer part of the circle) to 41 for component settings and 40 for hdmi settings.

However, some professionals per youtube video recommend that some sharpness artifacts be added to make the picture look crisper. That is probably why a "46" setting for movie component looks really great or better than a 41 setting.

My recommendations for standard mode settings (hdmi and component), therefore, are to set sharpness at 4 hdmi and 2 component, with additional settings between 6-7 for additional sharpness and perhaps a better picture, and for movie mode settings of 35 (hdmi) to 41 (component), with additional setting between 45-46, respectively, for a possible better picture.

Edit: I do not go beyond the recommended settings as to not introduce additional artifacts in the picture. It all comes down to preference.

March 20: Interesting Note: I had hdmi and component cables hooked up to the cable box and tv at the same time. When I removed and connected the hdmi to the blu ray, the tv's "component" picture appeared to improve. Is this possible or do I still need new glasses?

Hope this helps,

As always,

After you adjust or change the HDTV's picture settings, you may want to consider waiting about a week or a few days to get used to the picture, per recommendations on some web sites.

I haven't adjusted the settings for about a week and the movie component settings look great.

Vincentfam

I've had my set with your final setting since you posted them and I love the picture.

LDouglasLJr,

I have been a DIY calibrator for the last four years and just used the tricks of the DIY trade techniques. The key is getting a gamma level between 2.4 and 2.5, with consistent rgb levels. Contrast and brightness are controlled by using the ganging method. Also, sharpness is important. I use an eye one colorimeter and the free hcfr software.

By the way, what settings are you using? Component settings look great to me.

As always,

Vincentfam

I'm actually using both vincent. I have my Dish running through component and my PS3 using HDMI. In the upcoming months, I'll be switching everything over to HDMI.

I think both settings look great. I love movie mode but I seem to get more IR using it though for some reason. Or maybe I just notice it more with it, don't know.

Make sure your picture option size is set to 16:9 instead of screen fit. Screen fit shuts off the IR protection, per this forum. See if that helps.

Greetings,

Here are my updated sharpness settings for the above March 23, 2012 updated settings:

See "evolving sharpness" settings below if your cable signal is set to 1080i.

hdmi standard: 2
hdmi movie: 31
component standard: 2
component movie: 41

My viewing distance is about 9 feet. Pictures look a little better.

Vincentfam

Greetings,

I think that the above settings are about the best I can do, with some additional suggestions below.

The picture may look better if the HD signal is in 1080i. If you are not receiving this signal and you have cable service, go to your cable company's website to see if they have instructions on how to change the settings on your set top box. It is easy to do and AVS Forum may even have a thread for your box.

I do not know anything about satellite settings. Uverse may have easier ways to change signal settings.

For OTA (over the air antenna signals), I recommend using the component settings.

If you are watching SD channels, this thread suggests changing the color space from native to auto.

In the future, I may be looking at the differences between using native color space and auto color space. And I may slightly tinker with the hdmi settings to get the average gamma closer to 2.5. If I do, I will definitely post the new settings in this thread.

As always,

Vincentfam

Greetings,

I changed the blu ray player's display signal from 720p to 1080i and used DVE's 720p sharpness pattern, which changed movie modes' settings. Here are my latest adjustments to sharpness:

hdmi standard: 2
hdmi movie: 20
component standard: 2
component movie: 12

I used the blu ray's 1080i setting during the calibration because this is the same setting for my set top box that may deliver the best picture.
