Tools to Calibrate Your Screen

If you are obsessive about calibrating your screen to achieve maximum accuracy in game graphics or get a perfect native image for video editing or color correction, we are going to present five online tools to calibrate your screen (using the gamma function). Having an inaccurate gamma can produce a dark or washed-out image and you won't see colors precisely. For this reason, gamma correction is very important for luminance.

How to calibrate your screen

All the services offer resources to verify the screen's gamma, along with different guidelines and without having to download or install anything.

Lagom LCD Test

Lagom LCD Test is a tool for gamma correction of LCD screens. From the platform, you can test sharpness, contrast, contrast ratio, white saturation, screen settings, clock and phase, gamma calibration, black level, gradient, inversion, response time, viewing angle, and sub-pixel layout.

Simpel Filter

We continue with Simpel Filter, an online tool to calibrate your screen's gamma to the value: Gamma 2.2. Instead of showing you color strips, the platform shows you a square with four colors (red, green, blue, and gray). All colors have lighter, darker, and different intensity bands that fade to black. On each sector (four sectors) a grid will appear, which will help you see if your screen is calibrated.

PhotoScientia

We continue with PhotoScientia, a tool that will help you calibrate the gamma of your CRT screen. Unlike the other pages, the service allows you to check the CRT monitor for multiple gamma values: Gamma 1.4, Gamma 1.6, Gamma 1.8, Gamma 2.0, Gamma 2.2, and Gamma 2.4. Each of these values will open a pop-up window with three different image modules on a gray background. If you see the colors and the gray background, your screen is calibrated.

ePaperPress

ePaperPress is a very simple platform to calibrate your screen. The service shows you five gray bars, each representing different gamma values. To correct to the value 2.2, you will have to calibrate the gamma from the system, and you will observe how the 2.2 bar merges with the background, the 2.0 bar darkens, and the 2.4 bar lightens.

TFT Vanity Monitor Test

We will finish with TFT Vanity Monitor Test, a very good screen testing tool that has four modes:

• A simplified HTML version for Smart TVs, smartphones, and tablets.
• An HTML window with Flash technology.
• Flash and HTML technology in full screen.
• An executable program in full screen.

The tool shows different shades of gray to test how your screen distinguishes color tones against human vision. Remember that a good screen easily distinguishes gray tones at 2%.

With the five free websites, you can calibrate your screen's gamma easily and effectively.
