You hooked up a DSLR, ATEM switcher, or capture card. It looks fine in the test window, but when you enter the room, the screen goes black or MarketScale reverts to your basic webcam. High-end gear requires a precise setup. If the browser hits a snag (bandwidth limits, a "busy" signal, or a format mismatch) it cuts the feed. Here is the checklist to get your signal back online.

Force the Browser Handshake (Most Common)

If the browser panicked on the first try, a simple refresh won't fix it. You need to force a re-check.

Kill the Background Apps

Cameras can usually only serve one application at a time. If Zoom, Teams, or FaceTime is running in the background, it might be hogging the video feed.

Check Your Output Settings

Browsers like standard formats. If you feed them a weird signal, they will reject it to save bandwidth.

Pro tip: MarketScale standardizes all output to 1080p at 30fps (approx. 8 Mbps). Don't burn bandwidth sending us a 4K feed; we automatically downscale it anyway. Match our settings for the smoothest connection.

Swap the Cable

It sounds too simple, but cheap HDMI or USB cables are the #1 cause of signal drops.
