Precautions when checking

  • Set your browser's display magnification to 100%, clean the screen, and then look at it from a distance.
  • Displaying black, white, red, green, and blue in order makes it easier to distinguish between points that are not lit and points that are always lit.
  • 1px patterns may not be displayed accurately depending on the browser, OS, or display magnification process.
  • With OLED, avoid displaying the same bright screen for long periods of time, and use automatic switching only for as long as necessary.
  • If you feel unwell due to strong light or color changes, please end the test immediately.
