Troubleshooting

Second HDMI Not Working

Confirm InstantView is installed and running (check menu bar on Mac, system tray on Windows). If just installed, restart your computer. Try disconnecting and reconnecting the adapter.

Intermittent Display Flickering

Update InstantView to the latest version. Try a different HDMI cable. Reduce resolution to 1080p to test if the issue is bandwidth-related.
