A couple of days ago I received my new USB-A to HDMI 1.0 Dual Monitor 4K 60 HZ.
I've tried it with my monitor (a 4K LG 27UD88-W) but I haven't been able to get 60 HZ yet (only 30Hz with 3840 x 2160 pixels) despite of having installed the last USB driver version: DisplayLink USB Graphics Software for macOS v.5.0. The specs of my MacBook Pro are the following: Model: MacBook Pro Retina 13" late 2013 OS version: macOS Mojave 10.14 RAM: 16 GB Intel Iris 1536 MB graphics USB 3.0 I'm using the adapter with a HDMI 2.0 cable. I'd be very grateful if someone could please help me and give me some piece of advice about what I'm doing wrong or how can I fix this. Thanks in advance. |

Putting any other factors aside for the moment, the model monitor you mention having has an option setting within the on-screen display called, "HDMI ULTRA
HD Deep Color" This setting must be 'On' in order for 4K@60Hz to work via HDMI input. LG calls this out in page 23 of the manual for the display here -> https://www.lg.com/us/support-product/lg-27UD88-W |

First of all, thank you so much for the support and for such a quick answer. I really appreciate it.
The thing is ... following your advice I could make the screen work for 4k and 60 Hz (apparently). And I say "apparently" because on Mac OS there's a horrible lag, so It seems that the screen keeps working at 30 Hz. This is not happing on Windows 10: everything works like a charm on Windows 10. So ... I don't know ... maybe is a driver issue. Any idea or suggestion? |
