Eclipse interface icons very small on high resolution screen in Windows 8.1

The various icons and buttons in the Eclipse (Kepler) interface are very, very small on a laptop with a 3200x1800px screen. The red error decoration that appears to indicate errors on files is difficult to see unless my nose a few cm from the screen.

I've played around with adjusting the screen resolution and other settings in the operating system (Windows 8.1), which helps, but results in other applications appearing too large, and even then the Eclipse icons are uncomfortably small. Enlarging the fonts in the Eclipse preferences (window>preferences>Dialog Font) doesn't affect the icon size.

Is there any easy way to force larger icons? Any work arounds (I've used the Magnifier but that's a rather clunky solution)? Should I just buy a magnifying glass and keep it next to my mouse? Maybe someone should make a mouse with a magnifying glass embedded? :)

Thanks.

I struggled with this issue for a little bit too. I noticed a lot of you posted really complicated resolutions but there is a much easier way to do this! Its just a program and you shouldn't have to modify scripts, or install third party tools. The issue is related to High DPI scaling as mentioned above but what I think a lot of you are missing is that you can't directly modify compatibility settings on the launcher itself. The launcher and eclipse are two different programs! You need to browse to the Eclipse.exe and override the High DPI scaling option there. Once set, you can use the launcher as normal. The launcher will hit the executable, launch the eclipse.exe and since you set the compatibility settings on the .exe it will run using those settings. I spent like 10 minutes tracking down where the exe was so if its any help mine was located in: C:\Users\username\AppData\Local\Yatta\Launcher\installations\eclipse-ide-for-java-developers\eclipse.exe

Here is a screen shot of how I set my compatibility settings.

Eclipse.exe compatibility settings

And yes, the icons were super small before adjusting this setting. I tried setting compatibility settings on the launcher itself but it obviously didn't fix the issue. But after setting the override High DPI setting for the eclipse.exe icons are now normal size. Let me know if this works for others!

Had same problem, to resolve it, create a shortcut of the launcher, right click > properties > compatibility > tick on 'Override high DPI scaling behaviour' and select System Enhanced from the dropdown as shown on pic below. Relaunch eclipse after changes.

I found a reference that suggested adding the following to eclipse.ini

-Dswt.enable.autoScale=true
-Dswt.autoScale=200
-Dswt.autoScale.method=nearest

This doubled the size of the icons for me on Windows 10. I am using Eclipse Version: 2020-03 (4.15.0)

For anyone seeing this after upgrading their Windows 10 (post April 2018 update), the DPI Scaling Override setting has moved into a dedicated window:

The below change works seamlessly.

Quoting from CrazyPenguin's reply

"For those, like me, who found that even on the new Eclipse it wasn't scaled, see here: swt-autoscale-tweaks Basically I added -Dswt.autoScale=quarter to my eclipse.ini file."

I had this problem when I changed my default Windows 10 language from Eng to Italian, with Eclipse being installed when default language was Eng. Reverting Windows language to Eng and rebooting solved the problem. I don’t know what’s happened, Windows rename some folders like C:\Users translating it in your default language (i.e. C:\Utenti) and maybe this is causing problems.
