New in v1.17.2 Improvements: - Added "calibration points" to the brightness normalization feature, so you can create a custom brightness curve for each display. - You can now replace the default brightness slider with a custom VCP code. (Thanks @marc-frank!) - SDR sliders will now display when HDR is the only supported brightness method, such as on HDR TVs. (Thanks @Kirin-0321!) - Updated localizations. - Updated dependencies. Fixes: - Fixed window focus tracking not working. - Fixed errors displaying on the "DDC/CI Features" tab.
