Official LNXXA650 Calibration/Settings Thread - Page 6

Now I don't watch on Dynamic mode but my wife loves it. It's seems to me most people who calibrate and do reviews tend to dim the screem too much for my liking and make comments about how Dyanamic mode is not meant for household viewing. Like I said I don't prefer Dynamic mode, I use Standard mostly and do have Movie mode set-up to my liking(much brighter) but I can see why some who are coming from a regular TV or older style RPT HD set would enjoy the huge pop of an LCD set on DYnamic.

Thank you for your advice. I am still a little confused as to your settings. I am presuming I should enter them under "Standard Mode"? Is that correct? it seems like under some modes the options are greyed out. Also you listed 3 settings. Does that mean everytime you switch sources you go back and make all the adjustments all over again?

Thank you,
G.

p.s
Just to clarify my situation. I have in HDMI 1 my HD cable box.
in HDMI 2 I have my PS3 which I use for games, DVDs and blu-ray.

Thanks again,
G.

Thanks for your help Podol. I am using your updated settings and they are really nice and brings the whole picture together.

Mosh~~

I hate to keep picking your brain, Podol, but I'm struggling to understand the color space adjustments. I spent about 2 hours with my colorimeter, my laptop, and tv last night and have set my gray scale to D65. Now, I don't really understand how the color space controls work, they don't appear to be abosolute value (like if I set red to 0,0,0 red doesn't just disappear, it's just turned down). What's the best process for tweaking the color space? Start with primaries only? Do I work on green first? Any info would be great.

i know this is quite noob-esque, but i currently have to control chanels with my io remote and volume with my samsung remote, how do i make it so that i can use my samsung remote to interact with the io interface, and how do i make it so that it recognizes that i get my tv through the component cables (if I press the channel buttons on the samsung remote, it automatically switches to coaxial cable input)?
thanks

Finally received my 40A650 and boy oh boy is it a beauty!!!!!

I rolled the dice and purchased from buy.com of all places () but it worked out swell. I have a set with absolutely no issues. No dead pixels, no flashlights, no clouding. Any flaws (most every LCD has them) are not noticeable.

In fact, I'm using the old firmware and haven't even had the "shut-off" issue.

Which leads me to my question, should I upgrade to the newest firmware? Is it beneficial even if I'm not having any issues?

Thanks in advance!

Samsung states do NOT use the "shut off" firmware unless necessary though it includes other features. But you can download updates from the net w/out using the firmware fix.

My apologies if this is NOT the place to begin this thread...
I received my 46-650 today - ordered 4/14 and arrived 4/18 to Sarasota, FL in what was GREAT delivery service from CEVA.
My problem: I have plugged my Sony standard DVD player into the 650 via an S-cable but the 650 does not recognize the component. I set the S-cable name to DVD & searched for new components but alas the 650 is unaware. Perhaps I'm following instructions wrong via the source command but I don't think so and I've tried everything I can think of. I'd very much appreciate any advice you can offer. Has anyone else had this problem?

In 'Color space', you can control each primaries and secondaries' intencities and hues.
Red, for exmaple, you can increase or decrease intencity with 'Red' and adjust hue with 'Green' and 'Blue'.
Green, Green for intencity, Red and Blue for tint.
In Blue, Blue for intencity and Red and Green for tint.
Cyan, Red for intencity, Green and Blue for tint.
Yellow, Blue for intencity, Green and Red for tint.
And Magenta, Green for intencity, Red and Blue for tint.

First you read White and write down the luminance for easy processs.
And then read and adjust each 100% RGBYCM's intencity to reach 21.3%, 71.5%, 7.2%, 92.8%, 78.7%, 28.5% of the White luminance.
For easy calculation, let's say your White reads 100 nits, then Red should be close to 21.3 nits, Green 71.5 nits, and so forth respectively.

Because intencity controls are based on relative ratio, you can use virtually any sensors and meters.
But in tint adjustment, the better sensor you use, the more accurate result will come out.
Just adjust each colors position in CIE diagrams.
Red, green, blue primaries don't change much from original positions, though.
That's why TV's default color accuracy and gamut should be good.
Secondary colors, on the other hand, you can contol in much wider range.
But tint adjustment affects gray scale tracking, and vice versa.
So you may go back and forth between 'Color Space' and 'White Balance' for more accurate results.

What other features does the newest firmware include besides fixing the shutoff?

I had the same problem with my HDMI cable - its not your s-cable its the actual board, I spoke to the Samsung ppl and they said to return it to whoever you bought it from and get them to return it back to Samsung and not sell it as an open box product.

I'm getting a red sort of glow around red text when I use the 40A650 with my PC; that is to say it looks over saturated to where the text "bleeds."

Any ideas as to what's causing this? It only appears to be happening with red text.

I have my PC connected as follows: DVItoHDMI Cable>HDMI Input2>PC Mode>Standard Setting

Thanks guys!

What exactly does the "dynamic contrast" setting do? I am trying to reduce the appearance of some flashlights in the top corners and this setting appears to help somewhat. I tried the "black adjust" setting and it eliminated the flashlights but increased the black crush. It looks like this tv will be a challenge to calibrate if I also have to worry about the flashlights.

I finally finished my calibration and have my settings here:

http://spreadsheets.google.com/pub?k...6qdJzDxoPqrGZw

My color table and white balance a quite different from Podol's. Also, with my color space set to auto, my tv was already pretty close to the H.709 standard, that's why the color space number aren't too different from the default settings. Hope these help.

Edit: I added the actual excel sheet I was using if anyone what to use it as a template for their settings.

Sorry, my apology
I was little bit confused with LG60.
On A650, you can adjust RGB's intencities, but not much control over YCM.
You can control YCM's tints, but not much for RGBs.
LG's ISF mode can cotrol all primary and secondary colors' intencities and hues.

Setting may vary where you start calibration, which parameters you adjust first.
Different starting points lead to different settings, but similar results.
I checked your settings and they were very close when I measured my reviwing sample with Spyder sensor and HCFR software

Actually I have all different settings with actual DVD, Bluray titles or signal generators, and Photo Reaserch PR650, Minolta CS200, Minolta CS100A, Spyer, Eye One Beamer, Trichromat 1 from ColorFacts.
Also different software leads slightly different outcomes. Like HCFR, ColorFacts, and ColorTaster, etc.

Nice, i'll have to try this out and see how it looks on my set. I like how you put everything on a spread sheet too, nice work.

I tried Evil4blue settings. I guess they look good but it makes my LCD look like an old RPT, very dark. For now, I guess I'm just more into the brighter settings making the pic look more like real life instead of a slightly muted tone.

Evil4blue, could you verify following settings on your TV?
Backlight 5, Contrast 95, Brightness 45, Sharpness 17, Color 50, Tint G50/R50, and Color Space Red R29, G0, B0, Green R41, G42, B0, Blue R0, G13, B44, Yellow R50, G50, B0, Cyan R40, G53, B50, Magenta R39, G5, B62.
White Balance; R offset 22, G offset 25, B offset 23, R gain 25, G gain 25, B gain 20.

I'm checking model deviations and firmware differences

So. if you muck around with these settings and you don't like what you end up with, can you just reset to default or baseline again to start over?

Be cool if we could download each of your settings to our tv via usb flashdrive and then just see if we like and set back. Better than having to input these individually

Just being lazy...

Evil4blue, I'm really liking your settings. They seemed to have helped aleviate some of my red "bleeding" when connected to my PC; though it's still not gone. Any thoughts?

Podol, a comparison between firmwares would be excellent! I currently am running 102.3 and have no problems but if the latest firmware "M" enhances performance I may as well upgrade.

Thanks guys and keep up the great work!

Hi people whats up,

i need some help, i would like to go in to the system settings of the TV but my model number is LExx656 1AF so the code i got from the forum does not work for me.

i dint like the settings on game mode but i would like to turn on xvYCC on my own mode and DNIe and other stuff.

is it possible to activate that ?

thx in advance...

I'm using HCFR and an EyeOne Display 2. I'm having a problem whe I scan primaries and secondaries. It gives me some weird values, but when I do free measure, the values appear to be more consistent to what I see on the screen. I'm not sure what's going on, but I can't build a CIE Chart witht he wizard right now.

Anyway, what do you wan't me to check/report back from you settings.

I have a dark room (bedroom) so my settings look good to my eye, but try turning on Dynamic Contrast to low or medium and Energy Savings to Auto. Your picture should brighten quite a bit and not mess with the color balance. Also, I'd recommend downloading some cal charts and adjust your contrast and brightness by eye.

Download one of these:

Try turning your "Color" down from 50 maybe a few notches or in the color space setting, reduce the red-red slightly, may from 52 to 45.

Evil I'm going by the book and have my PC hooked up through the recommended HDMI input 2 using a DVI/HDMI cable and have the TV set to "PC" under source list; therefore, "color" and "color space" are greyed out.

If not set to PC mode, the picture gets grainy. Don't know why.

In any case, your settings are thus far superb!!!!! I'm in love and can deal with the "bleeding."

I'm using them for all sources; TV, PC, and PS3. They are especially incredible on the PS3; gaming and Blu-Ray are immaculate.

For anyone else considering Evil's settings give them a try. If using them for a PC turn the backlight to 6 for a little extra oomphhhh. And finally, if using them for a PS3 and you play games; try turning AMP to High, you'll be blown away if you like the "pop" effect.

Thanks again Evil!

Does this LCD have a blue-only mode for adjusting color with a color pattern???

Yes it does.

Mosh~~

That is awesome, I can't wait to get my 46.

I have modified Evil's Settings to add a little more widespread usability.

Samsung LNxxA650 Calibration Settings

They are to be used with TV, Playstation 3/Blu-Ray, & PC.

Let me know what you think.

I just wanted to thank all of you guys posting your calibrations... it has helped me a ton.

Question - for the CS Table the above has "5" for blue/blue where as evil and znutz both have "50". Was this a mistake on the Podols part?

Also where can I find what firmware I have?

Thx guys
