Hi, I have bought a 4k / 60Hz display a couple weeks ago. I am using it with my Macbook Pro. I can get it running in 4k, but it is stuck to 30Hz which is quite frustrating. My setup : My Mac : Macbook Pro retina 13" w/ touchbar 2018, Mojave 10.14.1 Screen : LG UD59 LG USA | LG 27UD59-B: 4K UHD IPS LED Monitor (27 Diagonal) USB-C to DisplayPort : https://www.amazon.com/gp/product/B075V27G2R/ref=oh_aui_detailpage_o00_s00?ie=UT F8&psc=1 I have also tried a USB-C to HDMI 2.0 cable, same results (same brand as the other cable) Is this normal? Is there anything I could do to get 60Hz? Thanks!
