I3 Touch Display connection is interrupted

Hi all,

We are using a brand new i3 Touch Display. The display is connect via a AT-OME-EX-KIT-LT HDBaseT Extender from Atlona and than connect to our MacBook Pro by USB-C via a Startech DK30C2HAGPD, with Video 1 connect via HDMI to the Atlona Extender.

When we plug-in the USB-C from Startech, the Display gets immediately a signal from our MacBook on HDMI 2. However, the connection is highly unstable and often the screen turns to black showing the HDMI 2 sign.

Could it be that the Startech DK30C2HAGPD is not compatible with MacBooks?

Thanks for your support.
