OXS Thunder connected via HDMI creates invisbile screen

Hi there,

i have received my OXS Thunder and connected the same using a HDMI Cable. Sound is received but also an additional screen to the left is created.
If i open the Display Option it shows as additional monitor. If i switch on “Show only Monitor 1” sound is lost.
How do i tell my PC that the HDMI source is sound only?

Hi Holger,

I am afraid you picked the wrong Forum.
