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. My mouse movements are choppy and it's very unsettling lol.
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.
- 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'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'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).
- Scaling down to 1440 or even 1080 still doesn't give me a 60hz option.
- I tried two different USB-C to HDMI dongles and multiple HDMI 2.0 cables, no change.
- I also tried all 4 ports with those two dongles and HDMI cables.
- 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... no supplemental USB-A or USB-C ports) dongle.
Anybody have any other tips to get this working, or at least new ones that I can try behind company security protocols?
Edit: I'm on MacOS Monterey v12.2.1. I'm including some screenshots of my Display Settings menu.
