If getting no display - check your refresh rate


Might want to add this to your set-up docs. For some reason my computer was picking “59 Hz” and the display remained dark.

Setting it to 60Hz… and it was alive!


Thanks for bringing this up, we will be sure to make a note of this in our FAQ and see if we can eliminate this possibility entirely in future versions of the firmware.


I found that the HDMI output on my computer (Dell XPS 15 9570) won’t drive a standard Looking Glass, because it’s HDMI v 1.something (1.4?) which won’t handle the refresh rate that the LG wants at full resolution. My workaround is to use a USB-C to HDMI 2 adapter to get a full resolution picture on the LG. It would be great if the LG could be made to accept lower framerate signal!
