PerfectLum can calibrate nearly any display and make even an older, commercial, or laptop display fit for medical imaging.

It is not required, but can be helpful for sensor driver installation.
To activate your license, you need to register it either automatically, if a workstation is connected to the Internet, or manually, if it is not.
Automatic:
Press “License” in the main window title bar and select “Registration/Activation”. In the window that opens, enter your serial number, choose automatic activation type, and enter your email address. Click “Activate” to complete the registration. Please note that automatic activation is possible only if your machine is connected to the Internet.
Manual:
Go to www.qubyx.com/index.php/register and fill out the form. Enter the serial number provided above, the generated workstation ID, and user information.
To get the generated workstation ID the form requires, open the “Registration/Activation” window in the software and select manual activation type. The software will provide a generated workstation ID.
When the filled out form is submitted, you will receive an activation code by email. Enter this code into the corresponding field in the “Registration/Activation” window of the software and click “Activate”.
You just need to download PerfectLum 4 and install it. All preferences and history from your previous versions will be preserved.

Yes, please go to PerfectLum preferences (Ctrl+P on Windows or Function+P on Mac) and uncheck “Update software automatically” in Application tab.
PerfectLum does not have any restrictions as to the highest possible luminance level. This depends on the capabilities of your display (maximum luminance is normally stated in display specifications). If your display is capable of reproducing 500 cd/m2, PerfectLum can calibrate it to this level.
Target luminance level can be defined in Preferences > Calibration Settings > Set White Level.
In PerfectLum you can check the calibration effect visually, using test patterns. After you have successfully calibrated the display, go to Tools > Display Test Pattern in PerfectLum main window. There you can choose one of the test patterns or any other image from your PC. Click “View and Check” to view the test image, and in the top right-hand corner you will see a button to switch off and switch on the calibration. If you want check the effect not on the test image, but just in general, use the PerfectLum LUT Loader tray icon (bottom right-hand corner). Right-click on it and you will see the name of your display(s) with a tick (this means that calibration LUT is applied on a display). Left-click on the display name to unapply the calibration LUT and to apply it again.
To reset your password, you need to close LUT loader and PerfectLum applications first. Then go to C:\programdata\qubyx\perfectlum and delete the full database file called storage.db.
*** Please note: all history data and settings will be lost.
Verify if the graphic card you are using has a LUT (Look Up Table). If you are using a laptop with a 2nd display connected, you may not be able to calibrate the external display, as laptop graphic cards usually have only one LUT. In this case select the external display in single display mode (you can do that in your OS settings or video card settings).
Verify if the sensor is connected correctly to the machine and if the USB port is active. Eventually change the port to test. Reboot the computer, and if you are still getting the error message, contact support(at)qubyx(dot)com for help on sensor installation.

3. select if acceptance test will be mandatory for your regulation by checking/unchecking corresponding box. If the box is unchecked, constancy tests will be already scheduled in the scheduler tab, if you check it – you need to pass acceptance test first;
4. to edit thresholds for your regulation, press “Parameter Editor” button. In the pop up window double click on a value to edit it and press “enter” to save it;
5. press “Save” to save your regulation and close the regulation editor.
