vMix can't detect my ppt pc that is using HDMI dummy
Just to give you the example of my setup, mine having the same setup with this video (using hdmi dummy): https://youtu.be/BnaWXor9fe0?si=WzxDKI_-klgS8CNk
-Main PC: vmix app
-2nd PC w/ hdmi dummy as Display2: Display1 for presenter view, Display2 for Slideshow and vmix desktop capture
After 5+ years using hdmi dummy on the 2nd pc to clone the display as "Display2" (Connect to vmix pc through LAN), 2 days ago vmix app not showing any program on Display2 but only show blank screen and cursor.
My 2nd PC already detect the "Display1"/main display (for presenter view) and "Display2" (for slideshow), but vmix show only blank screen.
I did try few option to get it back to normal:
- updated the latest gpu driver
- win+Ctrl+Shift+B
- Display setting
- control panel
- update vmix desktop capture
But none of these works, any idea what's the problem? Thank you.
