SpaceMatch DCM enables the VCGT colour management of any PC connected displays, avoiding the problematic issues associated with ICC Profiles.
Using ICC profiles for PC display calibration is fraught with problems when used within the film and TV industry, as many graphics programs attempt to use any ICC based display calibration as part of their internal image colour management. This can often cause the final exported image to suffer unwanted colour changes.
SpaceMatch DCM is a standalone .exe program. Simply unpack the download file and install the spaceman.exe program in to any folder of your choice; C:\SpaceMatch is a suggestion, and will be used as the location within this user guide.
When started SpaceMatch DCM will offer the chance to register and license. Registration details (and the option to register at a later date) are always available via the 'help\license' menu.
When first started SpaceMatch DCM will read and display any active VCGT (Video Card Gamma Table) data, either previously loaded via SpaceMatch or via an ICC profile loaded through an ICC based calibration system.
If this is the first time SpaceMatch DCM has been loaded and started on a given PC system and an active VCGT is displayed it is imperative that the ICC based colour management system that loaded the ICC profile is located and deactivated or uninstalled. Before progressing further make sure this is accomplished, and that every time the PC is re-booted no new ICC profile is loaded into the VCGT, as shown by starting SpaceMatch DCM.
Note: If the already active LUT from a previous ICC profile might be required again use the 'Save' button to save the VCGT LUT in the default SpaceMatch LUT format.
If multiple displays are in use make sure this is true for all displays by locating the SpaceMatch program window within each display in turn, and use the 'Read' function to read the VCGT data for each display in turn.
When first started a single LUT display window is active within SpaceMatch. New LUT display windows can be opened with the 'New File' button, or via the 'File/New LUT' menu. The new LUT window will also read the active VCGT data.
Assuming the LUT window shows no pre-active VCGT, as it should, the 'Load' button can be used to navigate to the required VCGT LUT and load it into the SpaceMatch LUT window.
Note: LightSpace CMS is used to perform the display profiling, and generate the required calibration LUT, with SpaceMatch DCM then applying the generated LUT to the display.
With the required LUT loaded into the SpaceMatch window, the 'Apply' button will apply the LUT, making it active by loading it into the video card driving the display SpaceMatch is presently located within.
With multiple SpaceMatch windows open, as in the above image, each LUT can be loaded by using the 'Apply' button within each SpaceMatch window.
At any time the LUT data held within the VCGT can be reset via the 'Reset Display Tables' button.
