2018 macbook pro, can I play a 120fps video normally (not slow motion) with an external 120Hz monitor?

Jian3917,

To clarify, the 2018 MacBook Pro only support 60 Hz refresh rate with external displays. You can check out the technical specifications below, depending on which model you use. Check the "Video Support" section for details:

MacBook Pro (15-inch, 2018) - Technical Specifications

MacBook Pro (13-inch, 2018, Four Thunderbolt 3 ports) - Technical Specifications

We hope this answers your question. Have a good one.

Hello Jian3917,

Thank you for reaching out about playing video to an external monitor. Any video that you are able to play on the Mac, should be able to be played on the external monitor.

Cheers!

Hey Jian3917,

Does this happen with only this specific video? Or are other videos affected?

We look forward to hearing back.
