Or, you can wait until March and check out the F8000.

If your looking for even bigger then 65", Samsung confirmed that they are releasing a few models in a 70"

Here's their 2013 lineup

Turboman, many thanks for your comments, they were very informative. I'm going to try calibrating at 75% luminance as you suggested to see if that makes a difference. I expect it will since my htpc is set to output 0-255 rgb

turboman, do you think you can get peak white high enuf with backlight at 1 or 2? there is a balance between checking black and still being able to get peak white high enough when you top out contrast, right?

That with the 0-255rgb looks Ok from the luminance levels you have at 0% and 100%. Just check those luminance levels when you set black level to low. The setting that gives max contrast is the right one.
I think your calibration with 75% will be much the same, since your 100% does not seem to be clipped, as greyscale is perfect. However it is still good practice to do gamut calibration at 75% luminance.
I would be concerned if you use patterns sent from htpc , as the PC video card might introduce unwanted changes. I would recommend AVSHD patterns from a blue-ray player.

You have the x-rite colormunki display or the display pro?
I'm thinking of getting the one... looks fun

I got mine locally at a camera shop, but here is an amazon link to the colormunki display http://www.amazon.com/Xrite-CMUNDIS-ColorMunki-Display1/dp/B0055MBQOM

If you search jestered's posts you will find one where he summarizes the pro/con of the popular meters that dont cost an arm and leg.

I agree with you that HTPC can do funny things to the colors (just go read HTPC forum here and see all the problems people have). I'm going to re-do the calibration by playing the mp4 files on the TV streamed from my computer using DLNA. That should result in a calibration perfect for the TV, and I will just have to deal with any problems HTPC is introducing later. Thanks again, you and jester have saved me an incredible amount of time getting started with all this.

I will update my original post once I have a calibration that looks as good as Jestered's.

cheers

Here's my results file you can load into HFCR calibrated results.zip 6k .zip file

Gamma


Overall pretty good but I think the Gamma levels could use some work. Any suggestions Jestered?

I have a different take on this. Luminance is affected mainly by backlight setting and contrast. And minimum black depends mainly on backlight and brightness.
Target is to have maximum contrast ratio. This can be achieved by increasing contrast and reducing backlight, for a given peak white output. Contrast can be increased as long as no clipping occurs. Clipping is most likely to show if one color drops in level at 100% on the greyscale. Samsung has set the settings of the Movie mode quite conservative in order to prevent clipping. Standard Mode is not so conservative and you have to watch out for clipping.
But for Movie mode, I think you can set contrast high. I think 10ks value of 93 is good, and I have mine at 100 (post 8007), and still no clipping. With contrast maximized without clipping, set your backlight to get the target you want.

Brightness setting: select a picture with 0%black for measuring, but the whole screen should not be black to prevent dimming. APL picture is good for that. Set a higher brightness and measure. Lower brightness and measure. Continue step by step until black level does not reduce further. The highest brightness level where you reach that lowest black is the best. If you reduce brightness further, you crush blacks without reducing minimumblack level.

Also, no point calibration color and tint. All corrections can be done in the CMS custom color settings. Do the custom color settings at 100% saturation and 75% luminance (safer in case you have some clipping at 100% luminance)

I have a Samsung UN65ES8000FXZA with back light issues... The corners have white spots (only when is black)
I called Samsung and they sent a tech out and they swapped the LED and that LED had dead pixels..
So they are going to tell best buy to exchange it for a brand new samsung tv..

My question is do you think the new one could have dead pixels or should i keep mine?

Also when are the new Samsung tv's coming out? should I wait for that so I can "upgrade"?

Thanks

If it's only only one dead pixel i would live with it, unless you sit 1ft from the screen, then yes return it.

my 2 cents

When the techs came out, they unscrewed it and same thing.

Granted, I've probably exchanged more sets for dead pixels than one can count..... but I only say this because I let a dead pixel slide on a previous set years ago and once I noticed it.... regardless of how small it may be..... human nature will have your eyes gravitate toward the dead pixel. Never again will I make that mistake again. As for likelyhood of another dead pixel.... let's just say out of 7 ES8000s I had, four of them had dead pixels.

As for the white spots, I agree with Derek.... the clouding should lessen fairly quickly. If it hasn't within a week or appears to get worse, then it may be an issue.

I wasn't able to get 75 and 100 to both be correct at the same time so I calibrated for 100 and left it at that.

I'm wondering if maybe this means I set my contrast too high and the TV doesnt have enough range. Anyway thats enough for tonight, if anyone has a 55" es8000 and wants to take a look at my meter calibrated settings, click the link in my sig.

Anyone ever hear of such a thing?

-to alter it, you can try other setting of gamma at picture settings (set gamma at +1), but then, your calibration will be probably off
-If you have calibrated grayscale and CMS (it seems to be OK), than you can flatten gamma curve by 10pt settings (you CAN NOT ALTER GAMMA with RGB GAINS)
-If you need to lower gamma (in your case 80% and up), tou need to RAISE green level at point 8 by click or two (no more at first iteration), then by measuring grayscale at 80% you have to set red and blue to be equal.
- Do it in small steps, then remeasure 70% and 90% grayscale as well.

Note : white consists from 71% of geen, 21% of red, 8% of blue, so if you need to lower gamma, you have to set higher luminance and common way for it is to first set level of geen.

Some guru calibrators advice for 2pt and 10pt systems is : Set RGB offset at 30% and RGB gain at 100%, then calibrate 10pt.
