Windows – way to set (or disable) DPI scaling for individual monitors (Windows 8.1)

Chrome has been lacking support for DirectWrite to render fonts on Windows. The issue you are describing is what happens not only on high DPI settings but also on normal (100%) settings.

There is a long and old thread on the Chromium issues website: https://code.google.com/p/chromium/issues/detail?id=25541

The developers said they already enable it on Chrome Canary builds but there is no timetable on when the regular version of Chrome will support it.

You can enable DirectWrite launching the latest Chrome Canary build with the following parameters:

# To enable DirectWrite:
--enable-direct-write --no-sandbox

# To enable DirectWrite and sub-pixel font scaling:
--enable-direct-write --no-sandbox --enable-experimental-web-platform-features 

The above parameters were listed by one of the developers in the same thread. The post link is https://code.google.com/p/chromium/issues/detail?id=25541#c61

Be warned the by disabling the sandbox feature you are compromising one of Chrome's security features.

Opera, which uses Webkit, has the same problem as Chrome.

FF and other apps that are DPI-aware are only system-aware. They need to be per-monitor aware to show up correctly on extended monitors. Otherwise they get scaled by windows (poorly, with the resulting blurriness). Currently very few windows apps are per-monitor DPI aware - IE11, Task Manager, Adobe Reader 11. Windows Explorer in Your screenshots is only system aware. I have the same problem with a 3200x1800 (15") laptop screen and an extended FHD monitor. These settings are enforced by windows if the "Let me choose one scaling level for all my displays" is not selected. Resources: http://technet.microsoft.com/en-us/library/dn528847.aspx
