Select the correct HDMI input on your display. Power cycle all devices (source, splitter, displays). |
| Picture flickering or intermittent signal | Poor quality HDMI cables; Cable length too long; Signal interference. | Use high-quality, certified HDMI 2.0b cables. Try shorter HDMI cables if possible. Ensure cables are not near strong electrical interference sources. |
| No audio | Audio format not supported by display; Loose HDMI cable. | Verify your display supports the audio format being sent. Check HDMI cable connections. |
| One display works, others do not | Faulty HDMI cable to specific display; Display compatibility issue. | Swap HDMI cables to isolate the issue. Check if the non-working display supports the resolution/refresh rate. Try connecting only the problematic display to an output. |
| 4K signal not displayed correctly | Display does not support 4K@60Hz 4:4:4; HDMI cable not rated for 4K. | Ensure your display supports the full 4K@60Hz 4:4:4 specification. Use Premium High-Speed HDMI cables. |
