Display Hot Keys - Instantly apply display settings with hot keys!

It's been a while since I posted here! Display Hot Keys has come a long way. I updated the OP. To see changes, visit the "Releases" page on GitHub: https://github.com/jon-mil-92/DisplayHotKeys/releases

A new release is up!

Thank you for continuing to actively maintain this utility!

I admit I haven't tried it recently, but you might have added it already: A hot key that displays the current mode on all displays simultaneously as a temporary overlay popup (monitor number, resolution, refresh rate, bits per pixel, hdr on/off, etc). Make the resolution and refresh rate the biggest text.

Basically like a temporary OSD status message that appears on all displays simultaneously. Whether as big transparent text (like an onscreen menu), or a small dialog at the corner of the monitor.

Sometimes I lose track of which is which, especially when unplugging/plugging a new monitor automatically changes the refresh rate of all displays, as Windows just simply loves to do. Gaming laptop lid opens/close is another wrinkle. The misfortune of everybody who plays with high-Hz multimonitor.

That's a good idea! I can look into this. I think I'm going to be creating some sort of additional settings menu at some point, and that could be an option in there.

As a Java developer, I am curious to know why this project uses JNI rather than JNA for native API calls ?

Great to see Swing + FlatLAF put to good use in 2026 !

Hey thanks! There are actually many reasons I did not, and could not, use JNA for this project. I'll go ahead and list some of them:

• Some of the APIs that I needed to use are not exposed with JNA, such as the DPI scaling API and the DXGI API.

• I have logic for retaining the user's intended display arrangement when changing display settings (Windows does not do this), and this is better suited in native code.

• I have native threads calling back to the Java code, and this works better with JNI.

• I need this implementation to be very performant because it is latency-sensitive, and JNA adds overhead.

On a side-note, Display Hot Keys 4.2.0 (https://github.com/jon-mil-92/DisplayHo ... tag/v4.2.0) was recently released, which includes some performance enhancements and a bug fix! Also, I believe I have finally gotten rid of the antivirus false-positives flagged by VirusTotal: https://www.virustotal.com/gui/file/7ab ... 3a485b2c1d

Thank you for the elaborate explanation.
