PatternSpace vs QuickGamma

PatternSpace is a macOS app for generating test patterns used in display calibration. It creates SDR and HDR patches, pattern grids, clipping checks, gamma tools, and color swatches. Its library contains more than 100 GPU-rendered patterns in Color, Checks, Geometry, Swatch, Gamma, and Clipping categories. Rendering uses a Metal EDR pipeline with up to 16-bit-per-channel output and patches locked to display refresh timing. It works with connected internal or external displays and requires macOS 15.6 or later on Apple Silicon or Intel Macs. The free plan includes 100+ patterns and 14 SDR reference presets; PatternSpace Pro costs $39.99, paid once and adds calibration integrations, unlimited Remote rendering, advanced HDR, and LUT and ICC export. DeckLink SDI Output is a separate $39.99, paid once and requires compatible Blackmagic hardware and Desktop Video 16.4.x. PatternSpace supplies patches but does not measure or automatically correct a display; display accuracy requires measurement hardware.

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.
