Official Sony KDL-XXZ4100 Calibration Thread - Page 3

If you modify the White Balance settings color will change a little, but you can always reduce color if it's oversaturated to you

thanks,yeah i found them to be really good. Try them for blu ray also,they seem to look really good. Only changes I would make is putting backlight down to min (unless you like a brighter picture for movies put it at 2 max) and power save on LOW. Thats just me because i love a dark picture for movies so ill either have power save low with BL at 1 or 0 with the settings I posted above.

hey did you try my settings? I also combined wide color with color set to 55 and it seems to really nail the colors making them look great. Also the black corrector on low adds some more pop because of the deeper blacks. Only question I have is if i only have brightness at 45 should i still keep black corrector on low or leave it off? And can someone explain what advanced CE does with a detailed explanation? will turning it on with black corrector definitely give black crush with brightness set to 45? does it add more pop to colors or lessen pop? Thanks in advance guys...

I'll try to calibrate again tonight. I am in a learning process

My gray scale is better now



White Balance Settings

R-GAIN : 0
G-GAIN : -5
B-GAIN : -14
R-BIAS : 2
G-BIAS : 0
B-BIAS : -4

Everything is the same as before , except

Color : 57

Looks like you're having fun w/your new toys (tv and calibration equipment). Technology is bliss, sometimes...

That it is

Thanks to everyone for posting their settings I been trying them all hehe.

Indeed

I am trying to help fellow owners at the same time

Absolutely. I don't know if you're married, but if you are, you can legally report this time as "charitable giving" to your spouse, not "Wasting your time messing w/the TV and that Cross-Eyed thing-a-majig."

My default gray scale wasn't very acurate. Too much blue, too little red.

Here are my settings of late. I'm still pre-update. Still waiting on my update. With the hue, temperature and white balance changes, I think the colors still look right to me while the skin tones have no red push. I.e., I watched the Giants-Browns game last night and part of tonight's Red Sox game and I think I know what those color shades are supposed to look like (i.e. the Giants' and Red Sox's red, etc.) - and I think they looked right.

But then again now I'm watching something called Earth: The Biography (Oceans) on Nat'l Geo HD and Vivid really makes a difference for this show. For some shows Vivid is just too much but for this show it looks really good. For a lot of the programming I've been watching (news programs, sports, sitcoms) I've gotten away with the settings from my previous post and they've made the skin tones look good, but for other programming I might want to blow it up a bit. So depending on what's on...

I've noticed on my 46Z that changing the white balance for a specific input changes it for all the picture modes - custom, standard,etc on that input. I wanted to compare white balance settings by having a different white balance in custom as compared to standard, with all other settings being equal between the two, but no dice. Changing white balance in one alters the other, too.

And, oddly enough, each color temperature has its own white balance settings. So if you change the white balance for "cool", you have not changed it for "warm1", etc on that input.

There are some LCD that doesn't even have a White Balance setting.

Read the Toshiba threads

Does anyone else's Z4100 have this characteristic? While watching hd cable, for instance ESPN, I calibrated my tv using vipers ps3 settings and modifying them slightly, and I got practically perfect blacks during the channel. However, and this is accentuated during off-angle viewing, the black bars which appear on the side just don't have a deep black like the actual black of the program. Is this a comcast feed type of thing? For instance, my ticker with the highlights and everything is pinpoint black, but the black bars are lighter and have a grayish tinge. CNN HD and Animal Planet HD have a similar effect. Can anyone explain why?

can someone explain what advanced CE does with a detailed explanation? will turning it on with black corrector on low definitely give black crush with brightness set to 45? does it add more pop to colors or lessen pop? Sometimes I see it make a difference and others I cant really see it doing anything,so im just a bit confused.

From my observations, ACE enhances the contrast by varying the brightness of the backlight, based on the over all brightness contained in the scene. As the scene gets darker, the backlight gets dimmer, making the blacks in a dark scene look even darker.

If you turn ACE off, the backlight stays constant as the scene gets darker, until a certain point and then the backlight drops suddenly to a low level. This is the auto dimming that people complain about, especially during credits and other dark scenes.

If you turn ACE on, the backlight starts dimming slowly as the scene gets darker, in a more smooth and continuous fashion, making the effect less noticeable. If the sudden drop in brightness bothers you when it is set to off, then the low setting is recommended to make the drop less sudden.

As far as I can tell, ACE only affects the backlight. It doesn't mess with picture processing in any way, like "black correcter" or "live color" or "adjusting contrast" etc.

Good explanation. I am going to test it

Very interesting,thanks for the explanation. So I understand during dark scenes NO MATTER WHAT the backlight is going to drop right? So i might as well leave it on. I thought by turning it on with black corrector on low it would add up to create black crush since both are working together,but if its going to happen anyway I might as well turn it on so it lowers the backlight in a smoother fashion. Now,does ACE do anything during bright scenes? I find the Z4100 to be overly bright so if during bright scenes the ACE will make the backlight brighter then I might have to think twice before turning it on. And does the low,medium,and high setting mean your telling it how dark/light you want the backlight to dim down/up?

jzig,also when you say with ACE turned off the backlight will dim down anyway,will it still go down as often as ACE or will it only happen during scenes with EXTREME darkness? If thats the case that means with ACE off it would only go down rarely, so i may want to keep it that way.

When ACE is turned off, it still dims the backlight very suddenly on extremely dark scenes. This almost never happens during over-the-air broadcasts so I leave it off on the "tv" input.

My dvr puts out a dimmer picture in general and I have to turn up the brightness to get it to look normal. With ACE off on that input the backlight is constantly flipping between normal and dim. It's very distracting. So I set ACE to low on that input. Then the backlight makes smoother transistions from normal to dim on a continuum depending on scene brightness. Its barely noticeable. I would prefer it if the backlight would just stay on the level that I set it to, but that isn't an option. In this case ACE low seems to be the next best thing.

ACE seems to make it's brightness decisions based on the inherent brightness of the source material. Not the screen brightness after you've adjusted it. Turning the brightness control up and down does not affect which scenes are made dimmer by ACE.

I don't see ACE having any effect on medium to bright scenes.

My advice would be to start with ACE off. If you have sources where you see the backlight flipping between normal and dim during the show, then set that source to ACE low to minimize that effect.

Or you may actually prefer a reduced backlight during darker scenes to enhance the darks (which is, after all, what ACE was designed for), then set it to low or what ever you prefer. Just knowing that it only affects dimming of the backlight during dark scenes has helped me decide how I like to use it. I wish I knew exactly how some of the other settings worked so I could make an informed decision about them! (like black corrector, for instance)

I don't watch tv in a completely dark room. We have a 75W focused spot shining on a picture on the wall along side the tv. Its a large room so the room is relatively dark. I like a backlight of 1 with powersaver off and light sensor off.

You've probably already tried this, but to get a less bright picture in a completely dark room, you could set the backlight at min and powersaver to max, that will give you the dimmest picture. Turning the light sensor on may make it darker yet in a dark room, but I didn't see much difference. If it is still not dark enough or there is too much change from light to dark scenes then try turning down the picture control to take the edge off of the highlights.

Hmm yeah but I wouldnt want to change my contrast settings because it workes our perfectly with the rest of the settings so ifi turn it down the picture would be less accurate unless i completely recalibrate everything. Ive found backlight at min with powersave on LOW to be pretty nice and dark (which is how i like it for movies) but high seems to make it too dark and disables the backlight setting,and ive never tried the light sensor before so im unsure about that. As for black corrector,i think its pretty simple what it does. It just takes all blacks part of the picture and makes them darker without touching any other color. The reason I was afraid of using ACE on low with black corrector on low is because I thought by combining the two of them it would make the blacks so dark that it would give black crush. If ACE off only dims the picture in extreme darkness I guess 90% of the time it probably wouldnt even dim the picture? One thing I can say is that on the PS3's XMB with the backround black ACE off constantly dims down and then brightens again and again. With ACE on low i didnt see it dimming down even once but it just keeps the backlight consistently dimmer the whole time. I want the damn backlight to stay as it is when ace is off but theres no way to do that. By turning it on LOW its as if I just turned my backlight down from 4 to 3 and it just stays like that,and if i turn it off it constantly dims down and then gets brighter again. arggg...

Is it me or does it seem like the autodimming goes away when I turn ON the light sensor.

I went with the CNET settings, looks good to me for the most part, but I feel reducing the sharpness to minimum really softens the picture and have set it at 6. Anyone else feel the picture is too soft when sharpness is set to minimum?

I do
