WHAT IS VERTEX
ACTUALLY SEEING?
Do not troubleshoot from the player menu alone. Vertex sits in the HDMI path and can show you what signal is really arriving and what is being sent onward. Read the line from left to right.
4K59.94 422 BT2020 12b HDR 594MHz 2.2
(line from the manual, p.19: resolution + refresh, chroma, colorimetry, bit depth, HDR flag, TMDS clock, HDCP version. With TV-led Dolby Vision the line shows RGB and 8b — that is normal, manual p.113.)
Resolution + refresh rate. “4K” is the picture resolution; 59.940 is roughly 60 frames/Hz timing. A movie may instead show about 23.976/24.
HDMI/TMDS signal clock class. Around 594 MHz is near the top of the original Vertex 18Gbps HDMI 2.0-class transport. It does not mean 593 Hz display refresh.
Color encoding. RGB and YCbCr are different ways of carrying picture/color information. YCbCr may additionally be 4:4:4, 4:2:2 or 4:2:0.
Bit depth. This is color precision per component. HDR commonly uses 10-bit-class output; Dolby Vision/LLDV paths can use formats such as 12-bit 4:2:2 depending on source and workflow.
Dynamic-range / metadata state. Use this together with the display's own HDR mode. A DV-capability EDID does not by itself prove the display is native Dolby Vision.
Copy protection handshake. A black screen can be HDCP-related, but do not assume HDCP is the cause before checking resolution, EDID and cables.
RX and TX — the easiest way to find the fault
If RX is wrong, look upstream: source settings, source cable, source EDID interpretation.
If RX is correct but TX/display is wrong, look downstream: Vertex routing/scaling, output cable, AVR/display capability or HDMI input mode.
Common readings in plain English
| WHAT YOU SEE | WHAT IT USUALLY MEANS | WHAT TO CHECK NEXT |
|---|---|---|
| 1080p when you expected 4K | The source has selected a lower mode or the EDID/path does not advertise the expected 4K capability. | Check active EDID, source resolution and HDMI input enhancement mode. |
| 4K24 works, 4K60 fails | The higher-bandwidth path is failing or not being advertised. | Check display/AVR Enhanced mode, Vertex EDID, cable quality and chroma/bit depth. |
| RX correct, display black | The source-to-Vertex side is working; investigate the output side. | Test Vertex → display directly, one output, simpler format, then AVR/second display. |
| HDR content but no HDR state | HDR is not being output, advertised or recognized somewhere in the chain. | Prove known HDR10 content, inspect EDID/HDR capability and display HDMI mode. |
| Only stereo audio available | The EDID presented to the source may advertise 2-channel audio. | Check Automix/custom audio flags and the actual AVR/audio path. |
| DV option disappears | The source no longer sees the required DV capability in EDID. | Check the selected Vertex EDID, then force a fresh handshake/restart the source. |
