- My phone won't connect after scanning the QR code? Make sure both your PC and phone are on the exact same local network (e.g., PC on Ethernet and Phone on the same router's Wi-Fi). If Windows Firewall pops up on first launch, make sure to click Allow Access.
- Why are some sensors missing on my phone?
SysCast only displays sensors that are actively checked (
✔️) inside MSI Afterburner's Monitoring settings. Open Afterburner, enable the sensor, and it will appear automatically.
