Although this software is a variant from the usual fare. I question the usefulness beyond just a slightly better color compensation program. Also the developer calls this a calibration, but to calibrate you need a reference instrument. In this case it would be a photometer for luminance and a colorometer for color temp and RGB value. You also would need a reference set like set reflectances and a color calibartion sheet to compensate for the illuminace of the room. If you want more control over your display do photo editing or something similar this would be a fine addition, with the right reference equipment this could serve as a means to calibrate but without that I really don't see a need to bloat your hard drive.

Also Installed fine on Vista Prem

Since most people's monitors are horribly out-of-adjustment, this is worth downloading for the manual alone. As I have a Media Center PC, I had already done a basic calibration of my monitors, so they didn't need much tweaking. Can this do what hardware calibration systems do? No, of course not. This is for basic adjustment. From the user manual:

Lutcurve is designed to provide optimal monitor display for these values:
Gamma:2.2, White Point:6500K, Luminance Level:80 cd/m2, Color Space:sRGB or native monitor color space.
The software is based on an article "Measurement of display transfer characteristic (gamma)" by A. Roberts. The calibration method is optimized for physiological sensibility of human eye to gray tones.

Note for color professionals: The software calibration method cannot give you color precision, because it does not take into account monitor RGB color coordinates. It is impossible to create correct ICC profiles without a measurement device.

PC display and color management are horribly complex. There are all sorts of issues with different devices and different applications. Here's a very small example of some of the settings: Vista color management settings (subset), refer to Windows Help and Support. NVIDIA color settings (subset), note also the options in the left panel.

Lutcurve doesn't address the full complexities of PC display and color management. It cannot be used with other gamma loaders, such as Adobe (standard restriction for this type of application). If you install it, you don't have to use it.

I wasn't able to trace the installation, because my installation tracing application crashes when comparing its snapshots. I doubt it clobbered files used by that application, as it was already open, and any DLL's, etc., that it uses would already have been loaded. Also, it didn't do anything bad to the registered DLL's. That utility has never crashed before, but the traces probably just exposed a bug; I'll use a file-sharing service and send them to the developer for analysis (after rebooting, in the unlikely event that that fixes things).

I am a software developer. First of all, thank you, a GAOTD community, for comments. I found some questions and misunderstanding here, so here is my comments and answers.

1. Lutcurve is safe to replace Adobe Gamma, because Lutcurve can be used with any icc profile. Operation system will use a profile created with Adode Gamma, and also a precise curve will be downloaded to your video card hardware. You can also safe use it with a Window 7 calibration feature.

2. The recommended here freeware programs, Adobe Gamma, Windows 7, Radeon and NVidia drivers have no feature to editing a monitor nonlinearity, so you will get much better image quality. Please read the software manual for possible advantages. Also, the program uses special methods to improve a quality of the visual calibration as a program specific.

3. If you want to get precise results, it is strongly recommended to use the program with a icc profile from a monitor manufacturer. Just look at the monitor CD to install it. Or search it in a manufacturer web site. The result will be very similar to a hardware-based results. Also some our users have reported better results than low-cost hardware calibrators, because your eye has better sensibility. A non-linearity is more perceptible in compare with a color error.

4. Users may report here no visual changes. But most general users have no experience in calibration and correct color corrections. So they may see no noticeable changes. These details very important for
image editing, printing and correction.

Also I know there is some old video cards those have no possible to download a LUT curve to the card. Also most of Microsoft drivers have no such feature. These users will see no any changes at all.

5. It is very important to place the software images on the center of the screen and on the central horizontal line for TN and S-PVA/MVA based LCD screens and laptops. So if your monitor menu covers the screen center, just move it. See the monitor manual for details. Also most monitors have advanced menu that already placed on a corner.

6. Almost all LCD monitors today need to be calibrated. Even NEC pro-series displays with a factory-calibrated curves have small nonlinearity that may be fixed with the program. Gamer or office monitors always have a 5-10% nonlinearity. Your monitor size and cost is not a factor to be sure about the monitor quality.

7. All the software bugs must be fixed. So if you have a crash or similar case, just contact to the support service. But in general, the program is stable.

8. The term "calibration" is correct. Color-space correction is "characterization". Hardware devices made two these actions. The program - only calibration.

I never used any such tool, but I really liked the way it worked.

Installed fine on XP and Easy to register.
A user friendly interface: Tabs at bottom from Welcome screen to different kind of tests.
User friendly instructions and controls to see the different aspects of your monitor.

Your monitor shows the immediate effect via color swatches (with options to type color value or use the navigation controls)

Can work with more than one monitor connected to your system. (I only had 1).

It displays online calibration result pixel by pixel. I liked the way it shows the gradient effects.

Overall it is a very informative and excellent piece of tool.

If color accuracy and the ability to match prints to your monitor are important to you, or you simply want the best colors you can get, I think having a decent hardware calibration utility is justified. Now if you’re seriously into digital photography then stuff like this is essential.

Right after the install, I did a basic run thru and was impressed by those results, especially the blacks. Then I reopened the program and begin the fine-tuning. The changes are done in real time, so there’s no waiting for it to process whatever adjustments you make (that’s a nice feature). After going thru the entire process my screen was significantly improved, it’s vibrant. So based on that experience I would recommend checking out this program to anyone wanting accurate monitor calibration.
