UGA-4KHDMI @ 1080p 60hz

[b.conway85]

I am trying to get 1080p @ 60hz to work on my UGA-4KHDMI on my M1 Macbook Air (MacOS 12.3).

I am only able to display 1080p @ 30hz, even though the macOS monitor setting is showing 60hz. I can visually tell that it’s 30hz and this was confirmed in my monitor settings menu.

I have followed all of the instructions from plugable support site below:
https://kb.plugable.com/questions/1185378

I have the latest DisplayLink Manager v1.6.1 installed.

I intentionally went with a more powerful DisplayLink chipset (DL-5500) to ensure I would have no issues getting a smooth 60hz. Any suggestions on how I can resolve this or other potential troubleshooting methods? I’m fairly savvy with computers and doing my own troubleshooting, but my google and forum searches have turned up nothing.

Thanks in advance!

Hello Bryan,

Thanks for contacting Plugable support! I’m sorry to hear about this display issue through your Plugable adapter, but I’d be happy to help!

This UGA-4KHDMI graphics adapter supports the following resolutions:

3440x1440 @ 50Hz
2560x1440 @ 60Hz
2560x1080 @ 60Hz
1920x1080 @ 60Hz
1600x900 @ 60Hz
1280x1024 @ 60Hz
1280x800 @ 60Hz
1280x720 @ 60Hz
1152x864 @ 60Hz
1024x768 @ 60Hz
800x600 @ 60Hz
640x480 @ 60Hz

3840x2160 @ 30Hz

This adapter should have no issues driving a monitor @ 1920x1080 @ 60Hz.

I’ve linked an article that helps change the resolution on macOS.

If these steps don’t help, I’d like to request some logs from your system to investigate further. Could you please keep the Plugable adapter connected to your system (with the non-working displays still attached), then navigate to our PlugDebug tool (https://plugable.com/support/plugdebug) and follow the instructions there?

Please set the subject as “Ticket #373034”.

Thanks for giving us a chance to help!

Thanks Omar! I was able to resolve the issue.

You inspired me to do some more digging in the Display settings on macOS. I noticed there were two resolutions for 1080p. When I select the one labeled “1920 x 1080 (low resolution)”, the 60hz option actually outputs 60hz.

So much smoother, like night and day from 30hz.
