Microsoft has improved font rendering in the latest Microsoft Edge Dev and Canary builds. Microsoft has improved the contrast enhancement and gamma correction to match the quality and clarity of other native Windows applications. Font rendering will also now respect user ClearType Tuner settings when applying text contrast enhancement and gamma correction.
To experiment with different values, run the ClearType Text Tuner. Note that Microsoft Edge must be restarted whenever the ClearType settings are changed, and that only the settings for your primary monitor are used.
This tutorial will show you how to enable or disable the Enhance Text Contrast flag for improving font rendering in Microsoft Edge.
