system - Mathematica 11 with High DPI 4k screen

My laptop has a 17 inch 4k screen, running Windows 10 and Ubuntu 1604. Both systems are set to 2x scaling. But Mathematica 11 (released 2016-08-08) is still blurry like version 10. Is there a simple fix to this problem?

Answer

The best thing to do, IME, is to set the default notebook zoom level to something higher. This way, the text is rendered crisply and at a reasonable size.

You can do that as follows:

1. Go to Preferences -> Advanced -> Open Option Inspector


2. Set Show option values to Global Preferences


3. Go to Notebook Options


4. Go to Display Options



5. Change magnification to whatever works for you.

Now, "100%" (default mag) will be rendered at whatever magnification you chose here.
