I recently purchased Epson Moverio BT-40 Smartglasses for which I’m using the Club-3D CAC-1332 adapter for any HDMI source, since these glasses have a USB Type-C connector. Works very well except for an intermittent flashing White line at the top of the image projected in the glasses. Hopefully I can get some advice on how to troubleshoot this. Here is a link to a short video of the issue:

Hi F13DFX,

Is this only when you watch an other screen with it or everywhere?

When I connect the glasses directly to the USB-C port on my Dell XPS15 laptop, the picture is perfect without the annoying line. Apparently I did aome research & found out that there are 5 identical rebranded adapter & they all use the Lontium LT6711 chip. I don’t have another USB-C display that I can test this Club-3D adapter with, so my glasses could be the culprit as well.

Test with a DisplayPort display using a USB-C to DisplayPort cable?

Same here, The glass is ok without the adapter, but a white line flashing on the top of the picture when connect through this adapter to any hdmi source, like Nintendo switch, ps4, MacBook Pro, windows pc…

Fixed on windows by using 59hz instead of 60
