Novideo sRGB

Novideo sRGB is a software utility that allows you to calibrate and correct screen colors to achieve accurate color reproduction according to the sRGB standard. The tool is designed to adjust the gamma, black and white points, and color temperature of monitors that lack built-in hardware calibration. It works by modifying the graphics card's color lookup tables (LUT) at the driver level, applying transformations that ensure compliance with the sRGB color space. This is necessary for graphic design work, photo editing, and other tasks that require color fidelity.

• Gamma correction. Adjusts the monitor's gamma curve to match the standard gamma 2.2 curve defined in the sRGB color space. This solves representation issues where shadows or highlights may appear too bright or too dark.
• White point adjustment. Sets the chromatic coordinates of the white color to achieve the target color temperature of 6500K (D65), which is the standard for the sRGB space. Compensates for any cool or warm color cast the display may have.
• Black point adjustment. Calibrates the luminance level of the actual black displayed by the monitor, improving detail in dark areas of the image and the perceived contrast ratio.
• Quantization mode. Controls the interpolation method used when applying the color correction LUT, allowing a choice between image quality and performance to minimize banding or posterization in gradients.
• ICC profile creation. Automatically generates and loads ICC color profiles containing the performed calibration information, allowing the operating system and compatible applications to manage colors correctly.
• Saturation correction. Adjusts the overall color intensity to compensate for oversaturation or undersaturation common in monitors with a gamut wider than sRGB, ensuring colors do not appear overly vibrant or dull.
• Luminance compensation. Modifies the correction curve to account for the specific luminance response of the monitor panel, resulting in a more accurate and linear gamma curve across the entire brightness range.
• Hue correction. Finely adjusts the hue of the primary (red, green, blue) and secondary colors to correct any deviation in hue that prevents faithful color reproduction.
• Persistence mode. Maintains the applied calibration after system reboots or driver updates by automatically reinstalling the corrected LUT to ensure consistency in color representation.
• Validation measurement. Provides tools to verify calibration results by comparing measured values from a colorimeter against the target values of the sRGB standard, generating delta-E reports.
• Viewing conditions simulation. Applies transformations to simulate how colors would look under different ambient light conditions, helping in work environments where lighting is not ideal.
• Multi-display management. Allows creating, saving, and loading independent calibration configurations for each monitor connected to the system, managing their LUTs separately and simultaneously.

The Novideo sRGB tool was created by the developer known as ledoge. Its development began in 2018 as a solution to correct color representation on monitors that lacked proper hardware calibration. The program is written primarily in the C++ programming language, using low-level Windows APIs to interact directly with the graphics driver and modify color lookup tables. The main motivation was to provide an accurate and stable software calibration alternative without the need for expensive specialized hardware. Throughout its development, advanced color management features have been incorporated, responding to the needs of professionals who require high color accuracy in their workflows.
