I bought an external monitor for my Macbook pro i7 9th 16”.
The monitor is a Gigabyte G27F 28” 144Hz.
when i want to set up the refresh rate i only be able to set 50 or 60hz.
i tried everything but not able to set over 60hz.
im connecting the monitor with an usb c hub adapter to HDMI.
i tried my macbook with a 120hz monitor and work perfectly and tried my monitor(with the same cable) on a widows computer and work perfectly at 144hz.
Hello alexroitman,
We understand that you're looking to set your external display above 60Hz. Per the technical specifications of your model of Mac, 60Hz is the maximum available setting. You can view this and more: MacBook Pro (16-inch, 2019) - Technical Specifications
Regards.
Hi Drew_7,
Thanks you for your response.
I think you are wrong. The refresh rate mentioned in the macbook specifications i think is about the retina integrated macbook display, not external displays.
As i said in my post, i connected an external display with 120hz and work perfectly(same mac, same cables).
Another friend test the same model display(gigabyte G27F) with his macbook and he can set up 144 hz...
alexroitman,
We understand, and appreciate your clarification. Since you've isolated the issue to your Mac specifically, the same model works on another device and another monitor works as expected, we recommend reviewing support options in your region. For further assistance with your Mac, review options here: Get Support
For additional assistance with your monitor we recommend contacting the manufacturer directly.
Cheers.
Macbook PRO cannot set 144hz
