LaCie 324 display analysis
- My settings for these tests was 120 cd/m2, Gamma 2.2, 6200 white point.
Color gamut
This is probably the biggest selling point. This display has quite a noticeable saturation increase over regular displays. The 324 color gamut approaches that of AdobeRGB with most colors. A notable exception is blues. Blues do not get quite as saturated as the typical LCD display. The gamut volume will vary depending on the software and instrument used for measurements.
Gamut volume
- 1,231,000 ( i1D2 & Blue Eye Pro)
- 1,135,000 - DTP-94 & CEDPro.)
Evenness
Visually this display looks uniform. With a 50% gray background in place, the edges look slightly warmer because of angle of view.
Angle of view
Color is warm toward center of vision, cooler to the outside edges. Perhaps more so on the up & down off axis than the left-to-right axis.
- One customer has reported trouble seeing shadow detail because of angle-of-view problems. According to him, the shadow detail is visible when viewed head-on to the display, but when the viewing angle is changed even slightly the dark areas appear "lighter" and it is hard to determine what is true shadow detail in the image, and what is a characteristic of the angle-of-view change.
Brightness
I did not test the minimum or maximum brightness of this display. It is capable of getting very bright. The internal graphics processing allowed it to get as dim as 120 without significant problems, although the LUT curves show a very sharp decrease in the curves in order to achieve this. I could detect a small amount of banding.
Internal LUTs?
Yes. 10-bit Internal LUT.
This can be accessed by LaCie's own Blue Eye Pro software, and also by ColorEyes Display Pro.
Calibration software - Blue Eye Pro
It does not appear that the Blue Eye Pro software comes with the monitor, however I was able to download the latest version from the LaCie website and use it with the i1D2 and the Optix colorimeters.
- This software is laid out very simply. It's easy to use. There's not a lot of complicated choices to make, and yet it seems to provide all the necessary choices: (Version 2 or version 4; LUT or matrix; custom white points and black points available.
- It makes adjustments to the internal video card, and leaves the computer's graphics card mostly flat.
DDC connection with CEDP
The automatic DDC correction option within ColorEyes Display Pro appears to work. However, it operates differently that the LaCie software. While the Blue Eye Pro software leaves the computer's graphics card mostly flat, the CEDP writes on both LUTS: the monitor's and the computer's - and makes some dramatic changes on both. Still, the resulting profile looks good to the eye.
Rotation
- There is no vertical/horizontal rotation of this display.
- This display raises and lowers about a foot, tilts from upright to laid back, and pivots about 350 degrees from left to right. (The bases rotates around to make it easy to "turn it" for other people to see.)
Highlights / Shadows
I am able to distinguish shadows of 5 L value difference, and it could probably have gone lower, although I did not test it.
Banding / grayscale
I can see a very small amount of banding (luminance) or posterization in the gray background behind the pitchers in the CHROMiX Frontier test image.
OTHER
Back Panel
Here is the arrangement of the back panel, left to right, as looking from the back:
(2) HDMI ports | DVI-D | Audio In digital | D-Sub | Audio In (Analog) | Line Out | USB In
Looking from the front
3 USB outs on the Left edge of display.
Uniformity details
Here is a look at the deltaE values representing the differences between the different sections of the screen.
This is comparable but maybe a little bit worse than the other wide screens I've looked at recently (Eizo CE2411, CE240W, NEC ) Basically, the average is from dE 1 to 3, with the worst being about 4 to 7.
