Symptom: The adapter is not recognized

Unplug all cables, restart the computer, and then reconnect everything.

Symptom: No signal when connecting to some monitors with DisplayPort input and output.

Some monitors such as Dell P2415Q and P2715Q 4K monitors have two DisplayPort connectors. One of the DisplayPort connectors is for DisplayPort input while the other one is for DisplayPort output. The DisplayPort output is designed for daisy chaining a second monitor. Please make sure to connect this adapter to the DisplayPort input.

Symptom: DisplayPort does not work at full 4K 60Hz resolution

The adapter supports DisplayPort 1.2 resolution up to 4K at 60Hz. You will need a 4K 60Hz rated computer and display to take advantage of DP 1.2 bandwidth.

Certain monitors including the LG 31MU97C, Viewsonic VX2475S, Asus PB287Q, and Philips 288P6LJEB may not support 4K 60Hz via DisplayPort. Resolution may be limited to 4K 30Hz. Contact the monitor manufacturer for this information.

Some smartphones and laptops such as the LG G5 (1080p) and 12" MacBook (4K@30hz) do not support 4K at 60 Hz video out.

Symptom: Audio is not transmitted to monitor through DisplayPort

Some monitors do not have built-in speakers. Therefore, audio must be transmitted separately. If audio is supported, please follow the steps below to select the correct playback device:

Windows:

1) Open the 'Sound' menu by searching or right clicking the sound icon on the taskbar

2) In the Playback Tab, select the display with DisplayPort

3) Click Set Default

MacOS:
