4K (3840x2160) resolution screens don't work with synergy

4 posts in this topic

Hi I have two computers first with 3 Screens: - Philips 190B 1280x1024 - Philips BDM4065 3840x2160 - Philips 180P2 1280x1024 second with 2 Screens: - 1600x900 internal - ACER AL1922 1280x1024 It does not matter what I try, e.g. if I try 2 computers with only one Screen each. If I attach the 4K (3840x2160) Screen, synergy does not work correctly, I cannot change computer. If I try another Resolution 2560x1920 it does not work either. If I reduce to 2560x1600, than it works again. So it looks like the synergy does not work with very high resolutions. Can this be fixed? I dont like to work on a screen that is scaled. Thx for your reply.

It still has the same issue (Version 1.7.6). I think it has something to do with the height or total amount of pixel in one screen. e.g. 2560x1600 works fine 2560x1920 does not work

I have a different issue on the 4k (HiDPI) screen of my XPS15 laptop (Synergy pro 1.7.6 and 1.8 beta). I use 175% scaling (a Windows feature to make things readable). The configuration screen looks very 'squashed'. It seems like the window dimensions in pixels are the same as on lower-resolution screens, but the window content is scaled and does not fit.

I have the same issue, however I have found a temporary fix: If you have external monitors connected to the computer running the synergy server, make sure that computers 'main display' is not the 4K display with scaling. Hope this helps you guys, Tom
