Troubleshooting HDMI-CEC & "One-Touch Play"
The Handshake Problem
HDMI-CEC (Consumer Electronics Control) allows your PS5 to turn on your TV automatically. However, different brands use unique trade names that can cause software conflicts. On the **PS5 Pro**, enhanced power states can sometimes confuse older 4K displays, leading to "no signal" errors or random input switching. This is almost always a "handshake" error caused by protocol mismatch.
| TV Brand | CEC Trade Name | Integration Level |
|---|---|---|
| Sony | BRAVIA Sync | Native (Best) |
| LG | SimpLink | High |
| Samsung | Anynet+ | Moderate |
| Vizio/Hisense | CEC | Basic |
Performance Warning: If your current display doesn't support these features reliably—or if you're experiencing "ghost power-ons"—it may be time to upgrade to a panel with better 2026 gaming firmware. See our Best PS5 OLED TVs guide.
Step-by-Step Fix
- Console Activation: Go to Settings > System > HDMI. Ensure Enable HDMI Device Link is toggled ON.
- Power Off Link: Toggle Enable Power Off Link to ON so your TV sleeps when the PS5 shuts down.
- The "Cold Boot" Reset: If sync fails, unplug both the TV and PS5 from the wall for 60 seconds. This drains the capacitors and clears the "Handshake Cache" in the HDMI controllers.
- Cable Verification: Swap to the original cable included with the PS5. If the issue resolves, your previous cable was likely an older 18Gbps (HDMI 2.0) lead.
⚠️ Tech Tip: HDMI-CEC data travels specifically via Pin 13. In many "fake" or budget cables, this pin is poorly shielded, causing signal noise that breaks the sync. Verify your cable quality with our Verification Guide.
