Troubleshooting a TCL Gaming Monitor depends on the issue you're experiencing. Here are general troubleshooting steps categorized by common problems:

1. No Power / Won't Turn On

• Check power cable & outlet – Ensure the monitor is securely plugged in and the power outlet is functioning.
• Try a different power outlet – Plug the monitor into a known working outlet.
• Check power button – Press and hold the power button for a few seconds.
• Look for LED indicators – If the power LED is off, the monitor may not be receiving power.
• Try another power adapter (if applicable).

2. No Display / No Signal

• Check cable connections – Ensure HDMI, DisplayPort, or USB-C cables are firmly connected.
• Use a different port – Try another HDMI or DisplayPort input.
• Try a different cable – Faulty cables can cause signal loss.
• Ensure the source is active – Check if your PC, console, or device is powered on.
• Select the correct input – Use the monitor’s OSD (on-screen display) to switch inputs.
• Try another device – Connect another PC or console to see if the issue persists.
• Check for bent or damaged pins – Inspect cable connectors for physical damage.

3. Flickering / Screen Tearing

• Check refresh rate settings – Ensure your PC is outputting at the monitor’s native refresh rate.
  • On Windows: Right-click desktop > Display settings > Advanced display settings
• Enable adaptive sync (VRR, FreeSync, or G-Sync) – If supported, enable in your monitor settings and GPU control panel.
• Try a different cable – Some cables may not support higher refresh rates.
• Update GPU drivers – Go to your graphics card manufacturer’s website and download the latest drivers.

4. Resolution or Aspect Ratio Issues

• Adjust display settings:
  • Windows: Settings > System > Display > Scale and Layout
  • macOS: System Preferences > Displays
• Check game settings – Some games may override system settings.
• Ensure GPU scaling is off/on – Depending on the issue, adjusting GPU scaling in NVIDIA/AMD settings can help.

5. Monitor Keeps Turning Off

• Check power settings – Ensure the monitor is not set to turn off due to inactivity.
• Disable power saving mode – Some monitors have aggressive power-saving features.
• Try another power outlet – Voltage fluctuations can cause the monitor to shut off.

6. USB Ports or Features Not Working

• Ensure USB-C or USB-A cable is connected – Some monitors require a separate cable for USB functionality.
• Check if the ports need activation – Some models require enabling USB features in settings.

7. Built-in Speakers Not Working (If Applicable)

• Check volume settings – Make sure the monitor volume is turned up.
• Ensure the correct audio output is selected:
  • Windows: Right-click speaker icon > Sound settings > Select monitor as output
• Try another audio source – Connect a different device to the monitor.

8. Ghosting or Blurry Image

• Increase refresh rate – Set the monitor to its highest refresh rate.
• Enable overdrive – Some gaming monitors have an overdrive setting to reduce ghosting.
• Try another display mode – Some presets (e.g., "Movie Mode") may cause blurring.

9. OSD (On-Screen Display) Not Working

• Check if the buttons work – If the menu won’t open, the button panel may be faulty.
• Try a power reset – Unplug the monitor for 10 minutes, then plug it back in.

10. Firmware Issues

• Check for firmware updates – Some TCL monitors have firmware updates available on the support website.
• Reset to factory settings – This can resolve software glitches.
