Another "native" vs. "calibrated" question

[Jeremy Payne]

In the several days that I have had my "new" Samsung XL20 I have learned a lot along the quest to get it calibrated and profiled.

Prior to this, I had never done anything other than profile relatively low-end displays in their factory default state with standard hardware/software combos ... happily, I might add.

Out of the box, the XL20 was so far off 6500K that my profiles from the native state just looked miserable.

So I decided I needed to calibrate first ... then profile ... and it measured out at about 10,000K in the native state.

Using the RGB sliders alone, I couldn't get a good profile - they all had a green cast.

Using a combination of a WARM 3 setting and some tweaks to the RGB sliders, I got a profile from there that seems to look ok.

My question is this:

Is a native color temp of 10,000K normal, or is there something wrong with this unit?

Sure doesn’t seem right. But I'd stop mucking around with the OSD controls, try to find a factory reset and try again.

I did find and hit the factory reset ... and then measured the monitor in its native state with the Spyder3Pro and I get a reading of 10,000K.  And did again ... and got the same.

Even though I can get to close to 6500K from there with a combination of WARM Setting + RGB sliders, I think I'm gonna call Samsung ... seems like 10,000K is just too far off to be right.

I don't know about 10K, but I can tell you that no display I've ever owned had a native whitepoint anywhere near 6500K (including CRT or LCD); they've always run higher than that before calibration.

The Samsung XL20 has a high bit internal lut so you want to get their software or Coloreyes (on the mac) so you can take advantage of the additional precision provided.

I tried their software and got errors - but I think that's 'cause I was (an idiot) trying (ie failing) to write digital data to the monitor LUT over the analog input.  I need a docking station for my W500 so I can use the real DVI.  In the interim, I'm stuck with what I'm doing now.

Here's where I've ended up ... the monitor in native state is quite bright and cold - temp measures around 9500K.  I used the Spyder3Pro to physically calibrate the monitor via OSD control to very close to 6500K and 120 luminance by a combination of a Warm 3 and a few tweaks to the RGB sliders.  I then profiled it with the Colorvision software.

I think it is a good profile ... but I'd prefer to be doing it via the monitor LUT since it has that capability.

I think once I get the dock, I'll get the ColorEyesPro software and do it "right".

I've learned A LOT in the last two weeks ... thanks, all!

[The dock may not be the answer. Many docks do  ot pass ddc commands correctly or completely

I've confirmed that my laptop video card is compliant, but you are right that doesn't guarantee anything if the dock doesn't do the trick ... more research ...

[jackbingham]

And for that matter just because the card says it is compliant.........DDC on the pc= Wild West

If my memory is worth anything, our XL20 had a native whitepoint (i.e. whitepoint after factory reset) in the 6800-6900K range. The two XL24's we now use are closer to 6700K. 10000K is indeed far off.

I'm definitely calling Samsung ... I'm at about 9500K after reset and after manual calibration and Spyder3Pro profiling, my Thinkpad display is giving me more accurate print matching than the XL20 ... that's not good ...

They claim 9500K after reset is not so weird - I called ... not sure I'm buyin' it, but I've recalibrated AGAIN and now have a profile that I'm very happy with and which now matches prints quite well.
