ViziCAL help

ViziCAL helps you keep medical displays calibrated, checked and documented.

ViziCAL has two parts that work together:

  • The ViziCAL app runs on each Windows computer that has displays to look after. You use it with a photometer to calibrate and check each display. The app also saves calibration reports. A small companion program, ViziCAL Apply, keeps your calibrations applied when the app is closed. A separate program, ViziProfiler, tests your displays before calibration and recommends the best settings to start from.
  • Your web account on the ViziCAL website keeps your organisation's licences, results and reports in one place. You can see every workstation and display, download reports, and buy licences there.

Where to start

If you're new to ViziCAL, follow Getting started. It takes you from creating your web account to your first calibration.

What you need

  • A Windows computer with the displays you want to calibrate.
  • A supported photometer. Some displays have one built in.
  • A ViziCAL licence for each computer.
  • An internet connection, so the app can activate its licence and send results to your web account.
