Official LNxxA750 Calibration/Settings Thread - Page 32

I think you can set xvYCC on any HDMI source, it doesn't have to be HDMI 1.3. I also notice a difference enabling xvYCC on my HTPC (colors look more washed out in comparison) which is why I always leave it off, as I know for a fact I have nothing that outputs this range natively and it's probably better matching out output levels.

Yes, after alot of reading and research I found myself having the settings left at the RGB + Extended 0~255 for the Xbox360 just like what I use for my PS3 RGB + RGB Full Range.

I wonder why the 360 update has xvYCC? I don't think the RGB Expanded option is even true 0-255, just 16-235 "Expanded" *even though the games are rendered 0-255 before any D/A conversion *

I think there is an misunderstanding. With the latest update, it provides YCbCr 709 and 601 Under "HDMI Color Space". When you select the YCbCr instead of the RGB, the xvYCC option become available on the TV menu just like PS3, if you select YPbPr instead of RGB, the xvYCC become available since xvYCC is the Extended Gamut YCC. YCC which is the short form of Y Cb Cr.

And the Reference Level is the 16~235 and 0~255 IRE Range thing.

Your knowlege of this confusing area is like an oasis in the desert ... at least to me it is.

Do you have a source for further reading to clarify all of this. In particular, what happens if the PS3, the source material, and/or the TV are not set correctly in regards the the 0-255/16-235 and the color space?

I tested the Rec709 disc with xvYCC enabled and the CIE chart was undersaturated badly. I never really understood why.

If you have all components set for xvYCC, you should be OK.
Yes, there are not any discs that are Deep Color encoded, but your components are matched and using a common color space.

In other threads, I have seen this analogy:

Think of it like watching a black and white movie on a color TV. The BW is not screwed up by watching it on a color set; the extra capability is just not being utilized.

Hello all just received my samsung 750 today im kinda new to setting these up im curious to know how I can remove the black bars on the side for watching standard def content im sorry for the noob question but im not sure thanks.

I tried this setup that you recommended on my LN46A630 and it looks awesome. Saw spiderman3, matrix reloaded and transformers and the picture quality just blew me away. Thank you zerog6 for sharing this info. I know you have done more, but for now I am just happy with this

But the xvYCC setting DOES affect the PQ if it's set to ON, even if the source is NOT outputting xvColor. All the super-white option in the PS3 settings does is extends the limitation level from 16-235 to 0-255 so you can see levels below 16 and levels higher than 235. To prove this, if you enable this option, the PS3 passes BTB and WTW. However, that doesn't necessarily mean that its actually OUTPUTTING these levels... essentially, the PS3 is still outputting 16-235 as ALL Blu-Ray and DVD movies are outputting 16-235 (and will continue to do so for a LONG time). This option is safe to enable because you will see no noticeable change in PQ (unless the source does support xvColor, in which you would see a better range in colors). So at this point in time, it's safe to enable super-white, although its not essential as there is no material that actually outputs xvColor.

Now, as for the xvYCC setting on TV's, it does the same thing... it increases the limitation from 16-235 to 0-255 BUT, since the PS3 is still essentially outputting non-xvColor (16-235), the TV seems to be mapping 16-235 -> 0-255. This makes sense too, because when I enable xvYCC on my TV, colors seem washed out in comparison, probably because its taking a smaller amount of available colors, and expanding it to a larger range. so again, if what you are OUTPUTTING supports xvColor, then it's recommended to enable xvYCC... otherwise you should leave it OFF. You may have read articles on the web regarding xvYCC/xvColor saying that if all the devices in the chain support it, then you can enable it, but that includes the source material.

As for Full vs Limited, it appears as if the PS3 is mapping 16-235 to 0-255 when you set your PS3 to FULL. To prove this, even if I set my PS3 to FULL, my TV to Normal and set BR/DVD to output RGB, I still can't pass BTB and WTW, meaning its just mapping 16-235-0-255 and its not actually displaying levels below 16 or above 235. So again, my recommendation is Low/Limited rather than Full/Normal because it appears as if the PS3 natively outputs 16-235 RGB (in the XMB anyway, I still dunno about games and theres no way to find out).

Does anyone know how to take the black bars off the side for sd viewing anyone know?

Hey Jersy, are you talking about vertical bars on 4:3 content, or horizontal bars on DVD content?

Also, random note: Been lurking about for a while since my last post, and gave a shot at Kakimoto's settings. They're nice, but they strike me as too dark (Dynamic Contrast + Power Saving + Dead Space = oh crap, I'm blind!) I'm gonna fiddle around with a few other calibrations, maybe even give a call to a local pro to see what he suggests.

I still see that the debate between xvYCC and PS3 Settings rages on...

When i watch SD content I have the view size at 16:9 and i see black veritcal bars on each side how can i get rid of these.

Check the source material. If you're using a cable box or something similar, there's an option on it to add the bars to the sides of SD/4:3 content, maintaining the aspect ratio. You can turn this off, but it will stretch the image to fit the screen format.

Ok i managed to get ride of the side bars it gave me 3 options to pick from 480p 480I and stretch i picked the stretch feature is this the best one to pick? Im still getting alot of blurrines when I watch NBA league pass in SD any one have any suggestions on how I can better then the picture. The HD looks amazing on this tv though.

SD is always going to be a bit blurry because of both the source material being non-HD, and most likely 4:3 ratio. If you want the best picture possible for SD material, you'll want to set the box to output all resolutions, both SD and HD (most of them have this option), and include the bars on either side of the frame to maintain the original aspect ratio. Set the TV to "Just Scan" and try out some of the calibration options listed in this section.

What is your service and reciever box model number? If the only options are 480p and 480i, you might want to consider trading the box in for a new one with your service provider.

If you go to pg.11 you'll see my final settings if you want to try those out.

Thanks for the settings zerog6. They look good but a little dark. I just want to confirm that the settings are using movie mode and not a different mode. Also, did you calibrate your sound settings as well. If so I am curious what your settings were as I am still unable to get acceptable sound messing with the equalizer. Thanks again!

If it's a little dark you just turn up the backlight. I did have sound settings but I don't remember for the life of me what it was, and I don't have the 750 anymore so I can't check it.

Thanks zerog6, will try it out. Out of curiosity, why did you use the movie mode and not the standard or dynamic mode. Can the same picture be obtained from the other modes and the mode is just the starting point or are there characteristics unique to each mode?

Anyone have sound settings they are happy with that they could post?

Movie mode is the only one which allows you to select the Warm color temp. Any other mode you use, especially dynamic makes the picture much too blue, and much too bright and contrasty. Movie is the only one which allows you dial in a true "correct" picture. Remember that even though it's the "correct" picture, you still might not like it and prefer it a different way. It's all about how your preference.

Does anyone have the original "Expert C-Space" service menu settings for the 1012.2 firmware update? I had the original settings written up and I've misplaced them (or I probably threw them out when I cleaned up my computer area without realizing it). If someone can provide them, it would be greatly appreciated.

Thanks...

Thanks will try that out. BTW I read you no longer have the 750, what did you get instead?

Cspace are the same as the Native, with primary colors at 50, secondaries at 50/50.

I tried yours and they look pretty good, but I have a problem with the gamma choices in WBMovie. Basically there are a BUNCH of them, and I don't understand them.

So, in my calibration I turned that off but don't think the final appearance is significantly different. The settings to get there are different, just not the final outcome. I think all these gamma settings mainly just change the Brightness setting anyway. At least it is the brightness setting that has to be adjusted to get back to my target gamma of 2.2.

I just received my replacement LN52A750 from Samsung with a build date of 10/08. I am seeing a lot of motion blur even with the AMP on high. The panel is SQ01. And the picture does not seem to be really sharp.
The first unit was purchased in July, but I do not remember what panel was used. Any feedback would be most appreciated.

I got a Kuro

The gamma settings in WBMovie do the same thing as the user level gamma setting. The thing is since you have a larger range of values in the SM, you can fine tune it a bit better than in the user menu. But they both have the same affect.

What gamma does is basically dim or brighten everything except black. You can think about it as a shadow detail enhancer. If you turn it up to high, the shadow detail will be over exaggerated, if you turn it down too low, you'll lose detail and crush blacks.

Hmmmm....Didn't make the connection. Thanks.

Hey guys!

On my set, I downgraded the TV to the original 1007 firmware it came with (from 1012.2 - to use Zerog6's final settings), I then upgraded back to 1012.2 and then I tweaked the service menu settings using KJGarrison's settings. I'm now ECSTATIC!! I didn't think the picture could look any better than it already was until I did this.

If the above seems kind of convoluted , it is only because the wife and kids left me alone for a whole afternoon and I had the free time to do some playing around with the TV. I was getting annoyed that the service menu settings kept changing everytime I incrementaly upgraded the firmware (to fix the audio and powersave settings problem) and the picture quality somewhat diminishing. To me the picture quality improved considerably when I did the above steps. I figured, why not downgrade to what I originally had when I got the TV and make the jump to the newest revision of the firmware.

If you try it, I'd like to get your thoughts on this and compare notes.

Thanks

So when it comes to Blu Ray movies on the PS3 , theres no way to adjust the HDMI black level? Is it always grayed out?
