Dealing with Eclipse and Very Small Icons on Ultra High Density Displays

More and more these very-very-high-resolution (UHD, Ultra-High-Density) notebook displays show up in my class rooms.These displays have 3100×1800 or even more pixels, making it great for watching high-resolution videos or for playing games (maybe?). But such a high-resolution makes many tools including Eclipse very hard to use, because the toolbar icons get so tiny that they are really hard to hit with a mouse cursor on Windows:

Several students reported the issue. These tiny icons make Eclipse and other tools like Altium really hard to use :-(.

Thanks to the hint from yet another student, I can share a solution for that problem :-): Create a short cut for the application (or create one) and then edit the properties of it. In the ‘Compatibility’ tab there you should find a setting ‘Override high DPI scaling behaviour‘:

Override high DPI scaling behaviour

Override high DPI scaling behaviour

Turn it on with the ‘System (Enhanced)’ option, and now the application icons are not scaled down and can be used normally.

Happy Enlarging 🙂

  1. Thank you Erich for covering this topic!

    I’m just in for buying a new monitor (UHD) and you already save me some unwanted google searching.

    Just a quick note here:
    According to bugzilla be sure to have the latest 4.7.1 release since it has many fixes for HighDPI (highly recommended if you are on Mac or Linux like me).

    PS.: You don’t need more than FHD resolution for competitive gaming (FPS).
