Created: 2024-09-23 by UserComp.com Editors

Are you experiencing issues with getting the full refresh rate when connecting your MacBook Pro to the LG UltraFine 340LL5C-B monitor using the UrG green converter? This article aims to provide you with a detailed explanation of the issue and a potential solution to help you get the most out of your devices.

Understanding Refresh Rates

A monitor's refresh rate refers to the number of times it can redraw the entire screen per second, measured in Hertz (Hz). A higher refresh rate can lead to smoother visuals, especially for fast-moving objects or when gaming. To ensure the best quality when connecting an external monitor to a computer, it is essential to match their refresh rate capabilities. This article focuses on solving the problem of not being able to achieve the full refresh rate of 50 Hz on a MacBook Pro when using the LG UltraFine 340LL5C-B monitor via an UrG green converter.

Problem Description

Some users have reported encountering issues when trying to connect a MacBook Pro to an LG UltraFine 340LL5C-B monitor through an UrG green converter, resulting in a lower-than-expected refresh rate of 50 Hz. While the monitor's native refresh rate is 50 Hz, the limitation arises from the connection's configuration, making it difficult to achieve the desired result.

Solution: Using a Thunderbolt 3 to HDMI Adapter

Although the UrG green converter allows the connection between the MacBook Pro and the monitor, it does not provide the necessary signal to enable a full refresh rate of 50 Hz. Instead, you can opt for a Thunderbolt 3 to HDMI adapter or cable. By utilizing the adaptor, you can eliminate the limitation and reach the desired refresh rate.

Step-by-Step Guide

Purchase a reliable Thunderbolt 3 to HDMI adapter or cable that supports 50 Hz refresh rate. (Consider our recommended product: Cable Matters Thunderbolt 3 to HDMI 4K Adapter).
Connect the adapter to your MacBook Pro using one of the Thunderbolt 3 ports.
Connect the LG UltraFine 340LL5C-B monitor to the adapter using an HDMI cable.
Once connected, go to your MacBook Pro's Display Settings.
Check the refresh rate by going to the "Display" tab and selecting "Scaled" and "Default for display" under the "Resolution" dropdown menu.
You should now see the 50 Hz refresh rate as an option. Select it and close the Display Settings window.
