I got amazing results with that combo.
Average DeltaE 0,23 max DeltaE 0,43 visible difference down to RGB value 3, smooth gradients with almost no banding, and white point at 100cd/m2.
Mind you the good performance was due to this particular calibration software, with Monaco Optix XR I couldn't get white point lower than 120CD/m2.
Well the Dell 2007FP has the same panel and I didn't have good luck calibrating it at all. Maybe the manufacturer really does matter. The 2007FP they had at work was pretty underwhelming.
It was pretty clear that the calibration software wasn't the issue as about 30 tones had to be clipped when calibrating for the native white point. I couldn't get the gradient to look white at the end no matter what settings I did. How is your LP2065 at default gamma? Anywhere near acceptable for photo work? How are the first 16 shades of gray (see link in my sig) at default gamma? It was one completely black screen for me. There was a mode in the OSD called "mac mode" (1.8 gamma I assume) vs "pc mode" (2.2 gamma). Mac mode seemed brighter (as expected) but the gradient performance was still pretty poor IMO. Thing is, photos didn't look all that bad. Midtones weren't bad but dark detail and bright detail was abysmal.
Well, the Dell has the same panel with the HP LP 2035, (LG.Philips LM201U04)
The HP LP 2065 has an LG.Philips LM201U05 panel, just like NEC 2090UXi.
For photo editing it's very important to be able to calibrate at 110cd/m2 and lower or your prints will come out darker than you see them.
I know that the Dell doesn't go below 175cd/m2 so it's totaly unacceptable for photo editing.
That's the reason I went straight with the ColorEyes display software.
With Monaco Optix XR Pro I couldn't get white point below 130cd/m2 unless I touch the RGB controls, and lowering the RGB values to 50% I couldn't still go below 120cd/m2.
I calibrated with ColorEyes Display using L* gamma, 16bit LUT based ICC V4 profile in DDC mode.
That means that the software took care of all the adjustments to calibrate and profile the monitor.
Brightness, contrast, and RGB values were adjusted internaly through DDC and no adjustments were made to the graphics card.
Unfortunately CED is a demo and I cannot try other calibrations anymore.
I will buy the software in a couple of months and I will be able to try other methods then.
I tried the tests at LCDRESOURCE and I'm very proud of my monitor's performance.
The Dark Grayscale Test is absolutely flawless showing the entire pyramid of dark shades, at the image tests I had no problem with any of the images and the Gradient Linearity Test showed 4 smooth gradients and 4 "staired" (if that's the word) gradients but I guess that this is what I was suppose to see.
The gray gradient was nuteral throughout the range.
The only thing that puzzles me though is a strange line of "dancing" cyan/blue sub-pixels that shows up at a specific gray shade.
It's neither hot or dead pixels though as they follow the shade everywhere.
I cannot guarantie that this performance is possible with other calibration methods/software.
Also the colorimeter used was the X-Rite DTP94 from my Monaco XR that is also the most recommended instrument for this particular software.
