QuickGamma is a Windows utility for adjusting monitor gamma without expensive calibration hardware. It can correct gamma to 2.2 and create an ICC profile with a VCGT tag containing data used to load a graphics card’s lookup table (LUT). QuickProfileLoader is installed automatically with the utility and can load a monitor’s LUT from that profile data. The listed capabilities also include LUT calibration, ICC profile export and multi-monitor calibration. Version 4.1.0.0 requires Windows 10 or higher; its installation file includes 32-bit and 64-bit versions, help files and no runtime libraries. QuickGamma is free for personal use, while commercial use requires written consent from the author. Private users may distribute the complete, unaltered installer, but not individual components. The author offers no express or implied warranties and invites donations. A SHA-512 checksum is published for checking downloaded file integrity. The maker also lists utilities for reading LUT and VCGT data and creating monitor ICC profiles.
