Closing Wordsīetter ClearType Tuner is a handy program for Windows 10 users who want to modify ClearType settings directly. A restart of the system may be required before the changes take effect on the entire system. The developer notes that this sets the application apart from the built-in tool as the functionality is broken in the latest Windows 10 version 1903 version of the operating system. The font smoothing settings set using the application apply to all connected devices. There is no option to change the text that is used, it is always 'The quick brown fox jumps over the lazy dog'.  Options to reset the settings to the default are provided as well. If you switch the antialiasing mode or contrast you may notice changes in the preview area immediately. Preview the results in normal scale and in a 400% zoomed mode.Ĭhanges that you make take effect immediately.Change the font rendering contrast manually (for RGB and BGR modes).Select Grayscale, RGB or BGR modes (Grayscale antialiasing or subpixel antialiasing using RGB or BGR subpixel layouts).
