Thanks so much!
I seem to have quite a realtime connection now 🙂
However there is one thing bothering me: unsharp text. I am on a Macbook Pro 2018. The hostPC has a 1440p monitor connected.
Via settings (client side) I lowered the resolution to 1920×1200 and “Match the client resolution upon connecting”. Now text is more readable (less vertically stretched) but still quite blurry.
