- Color Profile: Try "Standard RGB" or "Television"
# Some users report 30 Hz restores video signal
Success Rate: 40-50%Method 4: Cable and Adapter Verification
# Cable requirements for 4K displays:
✅ REQUIRED: Ultra High Speed HDMI Cable
- Rated for 48 Gbps bandwidth
- HDMI 2.1 certified
- Length: Shorter is better (under 2 meters ideal)
❌ COMMON MISTAKES:
- Old HDMI 1.4 cables (limited to 1080p@60Hz)
- Long cables (over 3 meters) causing signal degradation
- Cheap USB-C dongles (inadequate bandwidth)
# If using USB-C to HDMI adapter:

- Try different HDMI input ports
- Update receiver firmwareVolume Control Limitations
Critical Limitation:
❌ macOS does NOT support CEC (Consumer Electronics Control)
❌ Cannot control TV/receiver volume via Mac volume keys
❌ System volume slider only affects Mac's audio output level,
NOT the final volume on TV/receiver
# Workarounds:
1. Use TV/receiver remote for volume control
2. Third-party apps (limited functionality):
- SoundSource by Rogue Amoeba
- Audio Hijack
3. HDMI-CEC adapters (expensive, mixed results)
# Terminal volume control (Mac internal only):
osascript -e "set volume output volume 50"
# This only affects Mac's output level, not TVMicrophone Permissions and Recognition
