Monitor color calibration

  • Photo Friday — Photo Friday is a simple web page that is 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 is clearly distinguishable on the screen.
  • Online Monitor Test — Online Monitor Test is one of the better calibration websites out there. It is 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 as 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 you are thinking about purchasing.
