Arduino IDE on High DPI

[timhannah1988]

I have recently purchased a Microsoft Surface Pro 3 which has a High DPI screen. I installed the IDE and loaded it for the first time and it appears that the gui doesn't support DPI scaling as the menus and text is tiny and unreadable. I am having to use the device with a lower resolution so that I can use the software properly.

Is there any support i am missing or is it simply not supported yet. If the latter please can this be considered on future builds

I'd like to see a fix for this as well. I have the same problem with my Samsung Ativ Book 9+. With all the new high DPI displays, this will become more of an issue.

This seems more like a Java question. Arduino's IDE uses the Java JRE to do all those menus, so the bigger question is whether there's some way to tell the JRE to render them with more pixels?

Where is the UI code in the repro? Im knew to this project, but I'm willing
to dig in and look for a fix.

Here:

https://github.com/arduino/Arduino/tree/ide-1.5.x/app/src/processing/app

Please be aware there are 4 branches. Do NOT use the default "master" branch, because that's the code for version 1.0.x, which is being phased out. If you use that code, you'll have to redo everything to get it accepted.

Work within the "ide-1.5.x" branch, which is the latest version.

I have this problem too. On my Lenovo Yoga 2 Pro (3200x1800pixels) the interface looks very small.

4K screens are getting now more mainstream as well. Especially among tech savvy (arduino) user like us I assume ;-)

If anyone is still following this issue and cares about Arduino gaining graphics and font scaling, please test the build on pull request #2776

Any update on this? I'm using two windows laptops with HiDPI displays (one for work, one for home) and this is very annoying issue.

Maybe we have to switch from Swing to JavaFX which support HiDPI better (http://news.kynosarges.org/2015/06/29/javafx-dpi-scaling-fixed/).

JavaFX and Swing are two totally different beasts. They can integrate with each other, but it's more about rewriting the IDE that switching

I also value this issue. I can work-around the editing area by using 18pt font, but that only works in the actual code window. The Library and Board managers are almost unusable due to the small font being used on my high DPI monitor. Windows magnifier helps, but that is a kludge not a fix.

For reference, I'm on Windows10 64bit, and still see this behavior on IDE v 1.6.6.

+1 I am using the same trick as Sembazuru by boosting my font size, but it's still a miserable experience trying to code from a Surface Book.
