madVR 3D LUT Calibration Quick Start Guide
CalMAN Display Calibration Software interfaces directly with the Test Pattern Generator that is provided with the madVR video renderer. The generator automatically produces the required test patterns (patches) as CalMAN measures the display that is driven from madVR.
CalMAN controls the Test Pattern Generator as it creates an optimized calibration LUT file for the madVR. The calibration LUT file is then automatically loaded into madVR to apply calibration correction to the display. madVR alters its output signal, according to the LUT data, to correct the display performance to very accurately comply with the selected video standard (e.g. Rec709, sRGB, etc.).
Required madVR Software Version:
Version 0.87.19 or newer
Required CalMAN Software Version:
Version 5.4.0 or newer
Required CalMAN Workflow:
Color Cube (3D LUT) workflow
Software Setup
Open madVR Test Pattern Generator
1.In the madVR folder on the HTPC, locate and run the file, “madTPG.exe.”
2.Position the madVR Test Pattern Generator window in the center of the display to be calibrated.
Enable LAN Access
If CalMAN will be running on a separate computer from the HTPC that is driving the display to be calibrated:
On the HTCP that is driving the display to be calibrated -
1.Right-click on the madVR tray icon.
2.Select “Enable LAN Access.”
3.If a Windows firewall alert appears, select the desired options and click “Allow access.”
Note: It will be more convenient to run CalMAN either on a separate computer from the HTPC that is driving the display to be calibrated or on a second monitor on the HTPC.
Open CalMAN Color Cube workflow
1. Open CalMAN.

2.Load the Color Cube workflow - in the CalMAN main menu, select “Open Workflow Template,” then select “Color Cube (3D LUT).”
3.If CalMAN is running on the display to be calibrated, make the Test Pattern Generator window as small as possible, while still providing a full target for your color meter.
Display Calibration
Follow this procedure to:
a.Create a display calibration 3D LUT file for a video display that is driven from madVR.
b.Load the 3D LUT file(s) into madVR.
c.Validate the calibrated display performance.
Create Display Calibration 3D LUT
Proceed through each step of the Color Cube workflow in the normal fashion, using the following notes for madVR specifics.
1. Initial Setup section
In the ‘Initial Setup’ section of the Color Cube workflow, step through the following pages:
a.Session Setup - Meter Connect
1.Connect your color meter to the CalMAN computer.
2.On the Session Setup page, click the Find Meter button.
3.If your meter is listed on the Find Meters dialog, select it, then click Search. If your meter is not listed on the dialog, just click
Search.
4.Position the meter on the target display.
b.Session Setup - Source Connect
1.On the CalMAN Session Setup page, click the Find Source button.
2.On the Source dialog (see below), under Manufacturer, select “madVR.”
3.Under Model, select “madVR – madVR Test Pattern Generator.”
4.Enter the IP address of the target computer running madVR (if CalMAN is running on the same computer as madVR, enter the default local IP of 127.0.0.1).
5.Click Connect.

c.Session Setup - LUT Device Setup
On the CalMAN Session Setup page, click the Find 3D LUT Device button. Because you want to generate a standalone LUT file, you will use the Cube Generator device.
1.On the Find Display dialog (see below), under Manufacturer, select “SpectraCal.”
2.Under Model, select “SpectraCal – Cube Generator (madVR).”
3.Click Connect.
d.Session Options page
On the CalMAN Session Options page, you need to select the Input Signal Levels to match the display you are calibrating and the selected output levels in madVR (see below).
