Only thing I haven't tried yet is a direct USB-C (Thunderbolt 3) to HDMI cable, an HDMI 2.1 cable, and a non-hub (USB-C to HDMI only.I also tried all 4 ports with those two dongles and HDMI cables.I tried two different USB-C to HDMI dongles and multiple HDMI 2.0 cables, no change.Scaling down to 1440 or even 1080 still doesn't give me a 60hz option.I've read every answer and reply thread on 2018 MacBook Pro + LG 4k display = no 60hz, and none of the solutions have worked (got my hopes up with the Option+Click 'Scaled' menu in the Display System Preferences, but I still couldn't select 60hz, just 30 or 24).I'd like to not drop almost $50 on a hack-y dongle like the Accell USB-C to HDMI 2.0 Adapter, which might not even work based on the very mixed reviews I've read.I can't even attempt to use SwitchResX or solutions like rebooting into Recovery Mode and disabling certain features because this MBP is a work computer and has safety protocols built-in that block me from trying them.I'm aware of the limitations that Apple has set upon the USB-C ports when it comes to 4k60hz (as well as the differences between the capabilities of the left and right ports), and have done quite a bit of research already. My mouse movements are choppy and it's very unsettling lol. Like so many others, I've plugged my 2018 MBP into my TV's HDMI 2.0 port (no DP or USB-C ports on my TV) using a USB-C hub, and it only will display as 4k30hz.
