I just purchased a 13" newest macbook pro TB using it with LG ud88 via usb-c. The left ports work flawlessly outputting 4K 60hz. But the right ones only output at 30hz. I tried using an app to force it to do 60hz under different high dpi resolutions but no luck. Any ideas why this is the case? I thought they updated the macbook pro model this year to get even more bandwidth out of the right usb-c ports.
