darktears31On my laptop 4K@60hz works fine from HDMI port (without hub or converter) or from USB-C/thunderbolt3 port with USB-C-to-miniDP converter. But it shows only @30 from USB-C/thunderbolt3 port with USB-C-to-HDMI converter. No support from ASUS.
I have a thunderbolt 3 hub from CalDigit and 4K@60hz works just fine.
darktears31Absolutely sure the converter is 2.0. It's BASEUS ENJOYMENT SERIES TYPE-C TO HD4K+PD HUB CONVERTOR (CAHUB-W0G) tested by the Baseus local dealer on the other hardware (another windows laptop).
Well you need to make sure your USB-C-to-HDMI converter is HDMI 2.0+ compliant otherwise you won't get 4K@60Hz.
