variable refresh rate， https://www.monitortests.com/forum/Thread-Custom-Resolution-Utility-CRU Changes in 1.5: Added DisplayPort YCbCr color formats and maximum color depth (use the "Edit..." button at the top) Added HDMI 2.1 features including maximum FRL rate， and GTF (previously "Old standard") Detailed resolutions can now calculate frequencies for all possible pixel clocks (up to 167772.16 MHz for DisplayID 1.3) CEA-861 extension blocks are now called CTA-861 to reflect the standard's new name Added support for DisplayID 2.0 extension blocks Export now saves the original unmodified EDID if no changes were made ， while "HDTV" favors CTA-861. "LCD native" has been split into "Native (PC)" and "Native (HDTV)" for the same reason. "LCD reduced" has been eliminated because it was too arbitrary and only worked for certain resolutions. Try "Exact reduced" for an alternative. "CRT standard" is now "Automatic (CRT)" and includes 4:3/5:4 VESA DMT resolutions. Use "CVT standard" for the old behavior. Added "Exact" and "Exact reduced" to calculate exact integer refresh rates. Added common display standards: CVT， CVT-RB， and display stream compression New and improved timing options for detailed resolutions: "LCD standard" has been split into "Automatic (PC)" and "Automatic (HDTV)" to better accommodate different display standards. The main difference is how they handle resolutions greater than 1920x1080 @ 60 Hz and 21:9 resolutions. "PC" favors CVT-RB，。
