■ Symptom
- No video, audio/video noise, or flashing video occurs when PC and monitor are connected with Mini DisplayPort cable.
■ Checkpoint
- Use Mini DisplayPort cable provided with the product to connect PC and monitor.
- Check whether label saying Real 4k x 2k is attached to Mini DisplayPort cable.
■ How to fix
- Signal frequency is high for Model 31MU97, a high definition (4K) model, therefore audio and video output may not be complete
when a general cable is used to connect PC and monitor.
Please use Real 4k x 2k labeled Mini DisplayPort cable for connection.
