UHD - 4K Ui Settings

I was wondering what most people use as far as display scaling on UHD for Unreal? I was using a global UI scaling of 140% but the Unreal UI just looked too blurry and it wasnt working.

I have recently turned off display scaling for Unreal and it looks SOOOOO much better, although some of the text is small I think its worth it.

Just wondering what other 4K setups are using and if im missing anything to get the most out of Unreal dev in UHD.
