Just received my Looking Glass two days ago, but all I get are jagged edges everywhere and no clear images at all. I even bought a new 60fps USB-C to HDMI cable today, but keep getting the same jagged-edged images all the time.
I have a MacBook Pro 15’’ (Late 2018 model), with a 2,2 GHz Intel Core i7 processor and a Radeon Pro 555X 4 GB videocard with Intel UHD Graphics 630 1536 MB, running macOS Mojave version 10.14.6.
I already tried it in Mirrored and in Extended mode. Same results.
Any idea what else I can do to get the crisp looking images I tend to see on the YouTube videos and such?
Here are two photos to show the current status:
