Picture drops in the room after the laptop wakes from sleep.
HDMI handshake (HDCP and EDID) renegotiates on wake. Inline extenders, switchers or an overlong cable break that handshake.
Try this first
- 1Test direct without dongle first
- 2Set an EDID emulator or fixed EDID on the switcher
- 3Long runs via HDBaseT or fiber, no passive 15m HDMI
- 4Keep laptop on lock-screen, not asleep, during a meeting
When to bring us in
Mix of Mac, Windows and USB-C dongles breaks every meeting: install a room PC or BYOM bar so the laptop only feeds content.
