This program will help you to calibrate your monitor without a hardware calibrator device. High accuracy calibration is achieved by the high sensitivity of the human eye to neutral-color shades. The generated test patterns are based on an scientific article “Measurement of display transfer characteristic (gamma)” by A. Roberts and a new extended method for non-linear curves: sRGB, Rec.709 and BT.1886.
As compared to other programs in this class, Lutcurve has high accuracy and flexibility in configuring virtually any monitor. This allows you to get great results even in low-quality TFT LCD displays based on TN-matrix. Best results are on IPS, PVA or OLED. Multiple display configurations or notebook displays are supported.
Users Who Should Use Calibrated Displays
- Users working with videos and photos.
- Designers and artists who work with drawings.
- Professional photographers and videographers.
- Software developers and web designers.
- Just web surfers who love the image quality.
Disadvantages of Non-calibrated Displays
- Inaccurate reproduction of colors and shades.
- The loss of image detail in dark and light areas.
- Incorrect image brightness and gamma.
- Ugly and unkempt appearance of web pages.
- Eye strain when working at a computer.
The new version of the program has been significantly redesigned. Most of the code has been rewritten from scratch.
As a result, we got:
Improved Calibration Quality
Lutcurve 4 now supports new calibration standards for photographers, videographers, and colorists.
You can more accurately make color correction and color grading of your videos and photos, using the hardware settings of the monitor as much as possible.
The calibration curve is now more accurate by monitoring the area of shadows, lights and smoothness of gradients.
Test images have been improved. The experience of visual calibration using older versions of the program is taken into account.
Modern Calibration Standards
It is now possible to expand the visual calibration technique to use non-linear curves used in the new standards.
- Photo and Internet: Gamma 2.2 and sRGB.
- Video production: Gamma 2.4, BT.1886 and Rec.709.
- Support for OLED and high contrast displays.
Settings are now independent for multiple monitors. And accuracy is enhanced by improving calibration images and revised user instructions.
Here is a simple and quick calibration test for most monitors:
your monitor might need to be calibrated!
Note: this simple online test is correct only if you have display DPI settings 100% and no additional browser zoom.
It is safer to check the calibration in the program.
Calibration of any Display
Atrise Lutcurve lets you correct nonlinearity of displays, especially noticeable on LCD monitors. The count of calibration points is not limited, which means you can calibrate even an aging display.
The quality of the calibration depends on your carefulness and may be very approximate to hardware calibration results and better.
Multiple Display Support
A multi-display PC installation is also supported on all supported OS including Windows XP.
It is possible to match two display colors.
Multiple Calibration Controls
All values are adjusted by numerical values using the Up / Down button controls. The whole process takes about 15 minutes to complete.
Easy Steps to Calibrate
The program walks you through adjustments in a step-by-step manner.
See Before and After
Once the display is calibrated, it takes a bit of time to get over the gee whiz factor that comes from seeing that the images on your display closely match reality.
