In Windows you can adjust the ClearType settings (with the ClearType Text Tuner) but to my knowledge there is no way to manually tweak them (as in moving some bars or something), you are only given these screens asking which font looks the best (reminds me of the eye doctor).


I would rather manually adjust whatever it is these boxes are tweaking but I don't know if there is a way.

I recently switched to Windows 10 and the default settings just didn't seem to look right to me and no matter how I tweak them I can't seem to get them correct. Curves seem to look more jagged and things seem to "bleed" over into the next pixel more than they should.

  • this might be the fault of graphic drivers and/or some windows-10 dialog scaling.win-10 is a bit of a stylistic mess and some of the dialogs are bitmaps scaled up, which do not get touched by Cleartype. Some MS software uses greyscale smoothing instead of subpixel, and then browsers can be set to use different type rendering. For the GPU driver side: I know that AMD/ATI used to enable overscan scaling for monitors when attached via HDMI, which causes minor quality issues especially with the windows UI type

  • I am using an NVidia GTX 780 through an HDMI for what it is worth. Thanks for the insight, hadn't considered it might have anything to do with the drivers (it wasn't a problem on Windows 7 but Windows 10 has a different driver as far as I can tell) Dec 7 '16 at 17:14
  • @CaptainMan Have you ever resolved this / reached more insight in what ClearType does exactly? I have the same problem, and that "choose the best" dialog doesn't really help for the fonts I use most.

  • @MrLister ClearType is Microsoft's proprietary tool that handles anti-aliasing by adding colors to make it look nicer. That's a very rough explanation. Either the problem has vanished or (more likely) I have stopped noticing what I thought was blurry. Sorry I don't have a more satisfying answer :( Jul 2 '19 at 14:14
  • @CaptainMan I'm aware of what is is, but I still don't know for sure what those 5 screens of choices all do. As you said, one regulates subpixel rendering, but that leaves others where I just have to guess.
