This issue is about white balance, not the color gamut. It is not that x0.3127, y0.329 are intrinsically incorrect for Sony OLEDs, rather it is that the 1931 standard observer equations used to...

To provide some perspective, the result of your 729-color calibration is an average dE of 0.6, with over 90% of the colors below a dE of 1.0. This is just about as good as it gets. You are focusing...

We can provide the disc as a digital download on request so long as you have the ability to burn Blu-rays from an iso image. Yes, ChromaPure works well with this meter. I don't know how anyone other...

ChromaPure uses the four-color correction method developed by NIST. This uses xyz, which is not the same as XYZ. xyz is the standard xy coordinates and z is 1-(x+y).

Lower the display's main Color control. You'll then have to use the Radiance controls to raise luminance elsewhere as appropriate.

I am a little puzzled by the discussion of degrees of success with respect to meter profiling. The 4-color NIST technique is a purely mathematical calculation which, if implemented correctly, will...

This screen shows the native xy values of both meters, and it is from this that the correction matrix (which is not shown) is created.

The biggest variable I have found is warm-up time of the display. Always wait at least a half an hour before taking measurements and then do that consistently.

Well, NOTHING is exact. Perfection does not exist. I don't know what you mean by "tolerance levels" in this context.

First, the problem with the 1201 and plasmas, as you certainly know, is repeatability. As you also know, this problem is mostly confined to red. It doesn't exist at all with blue, and is present to...

One of these days I am going to put a definitive end to this topic. I have profiled hundreds of D3s using a JETI 1201 on several different display devices. I have all of that data archived. When I...
