First sorry for my english.

I have Mac Mini 2018 i5 32 GB RAM + 32 4k Eizo monitor (new now). I have very slow UI in osx wehn i set scaled resolution and I notice small lag at native res...

I am thinking to buy egpu.

What I would like to know, if eGPU if it speeds up OSX UI not only some appplications ? 

And which is the best silent GPU compatible with OSX ?


Thank you very much

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

@ondrej-p, Which cable are you using to connect the Mac mini to this 4K monitor? HDMI is typically not ideal in macOS. Often time it results in low refresh rate (30Hz) which makes the UI seem sluggish. Try USB-C to DisplayPort cable if possible. You can also try SwitchResX to set the right desired resolution and refresh rate. If all those options fail then look into eGPU.
