Can you provide short info what easyworship is to the folks, please? Is it slides with bible verses to blend over, or song verses to project? Or something else? Whats your setup with merely pc's?
To be honest, a short answer to your second question, Reme70. Wireless from another pc to the obs-station with a capture card you can use wireless hdmi transmissions. Look for something as "Hollyland MARS 400 pro" or something. But be aware, these are fast 5ghz links. If you already have alot of w-less 5ghz stuff in the room (for instance w-less control of tablet mixers), it may worsen the sings. And there is a small but noticable lag of .1 or .2 seconds, if that needs your attention.
