Calibrate using online utilities
There are a handful of web-based calibration tools that help you manually adjust your monitor settings, ones that essentially ditch the automation in favor of a bit more customization and control.
- Display Calibration — Display Calibration will let you view several test patterns and samples of what a properly calibrated screen will look like. Although the site isn’t the most aesthetically pleasing and it’s rarely updated, the on-screen calibration tools for brightness, contrast, color depth, and screen resolution can prove useful if you can’t access any built-in calibration tools.
- Photo Friday — Photo Friday is a simple webpage that’s designed to help you calibrate the brightness and contrast of your screen. Just adjust the monitor settings until the transition of tones from black to white are clearly distinguishable on the screen.
- Online Monitor Test — Online Monitor Test is one of the better calibration websites out there. It’s lined with a slew of interactive tests to help you adjust your monitor’s screen colors and to see if your monitor can produce smooth gradients. There are also tools for pinpointing damaged pixels and backlight bleeding, rendering the website one of the more robust web-based calibration tools to date.
- The Lagom LCD Monitor Test Pages — The Lagom LCD Monitor Test Pages are handy, both online and offline. The website not only allows you to adjust various things such contrast and response time, but it also allows you to download the images as a 120KB zip file, so you can check any monitor in-store that your are thinking about purchasing.
