I just bought a M2 version Macbook Pro today and connect it directly to an external monitor (4K). But the highest refresh rate I can set in setting is only 30hz.
I also tried to connect the monitor to the usb-c port with a HDMI to usb-c converter and stuck at 30hz also.
Does anyone know how to get a better refresh rate? Thank you!

HDMI cables you want for HDMI-only Displays (higher resolutions than 720p TV sets) are marked as Certified with an anti-counterfeiting tag and are labeled:
"Premium High Speed HDMI cable" or that + "with Ethernet" --OR--
"Ultra High Speed HDMI cable" or that + "48G"
Cables with No Certification tags are good for your standard 720p TV set, and not much more.
what screen size MacBook Pro?
what make&model display?
14 inch.
Monitor is Dell P2715Qt
Ok. I will get a cable. But not sure that's the reason as I have been using the same cable connecting macbook to a 4K TV and it seems quite smooth.
External Monitor is stuck at 30hz
