VERTEX TROUBLESHOOTING / BEGINNER

PROBLEM →
CHECK → FIX.

Choose the symptom that matches what you see. Follow the checks in order and stop as soon as you find the stage that changes the result.

Golden rule: do not change five settings at once. Start with Source → Vertex → one display, prove SDR, prove HDR10, read RX/TX, then add advanced EDID, LLDV, AVR and the second display.

PROBLEM 01

NO HDR

Known HDR content plays, but the display stays in SDR.

  1. Confirm the source is actually outputting HDR10 with known HDR10 material.
  2. Read Vertex RX. If RX is SDR, investigate source output and the EDID presented to the source.
  3. If RX shows HDR but the display does not, inspect Vertex TX, the output cable and the display/AVR HDMI Enhanced/UHD input mode.
  4. Return to one source → Vertex → one display until HDR10 works.
PROBLEM 02

NO DOLBY VISION / LLDV

The source does not offer Dolby Vision, or an LLDV workflow never starts.

  1. First prove normal HDR10.
  2. Confirm the exact source supports Dolby Vision/player-led DV.
  3. Select the intended DV/LLDV-capable Vertex EDID, then force a fresh HDMI handshake so the source reads it.
  4. Check the source menu again and verify the actual Vertex RX signal.
  5. Remember: an LLDV EDID does not turn an HDR projector into a native Dolby Vision display.
PROBLEM 03

WRONG / PURPLE / GREEN COLORS

Picture exists, but color is obviously wrong.

  1. Return source color output to Auto where possible.
  2. Compare Vertex RX color format with what the downstream device can accept.
  3. Check RGB/YCbCr and Full/Limited range settings; do not force mismatched range settings at both ends.
  4. Remove custom EDID/scaling temporarily and retest the simplest path.
  5. If the issue only starts with a DV/LLDV workflow, return to proven HDR10 and add DV again as the only change.
PROBLEM 04

WASHED-OUT BLACKS / CRUSHED BLACKS

Image is grey and flat, or dark detail disappears.

  1. Suspect a video-range mismatch before changing calibration.
  2. Use Auto range as the baseline on source/display where available.
  3. If one device is forced Limited (video range), make sure the other side is not forced Full, and vice versa.
  4. Verify with normal SDR/HDR material before changing gamma or HDR tone controls.
PROBLEM 05

NO AUDIO

Video works but audio is silent.

  1. Check what audio capability the active Vertex EDID advertises to the source.
  2. If using an AVR, test Source → AVR directly and then Source → Vertex → AVR.
  3. Use a basic PCM/stereo test to prove the path, then re-enable bitstream/multichannel formats.
  4. Check Vertex audio routing/de-embedding only after the HDMI audio path itself works.
PROBLEM 06

ONLY STEREO

The source only offers 2-channel audio.

  1. The source may be reading a stereo-only EDID.
  2. Inspect Automix/Custom EDID audio flags and the downstream AVR capability.
  3. Do not advertise 7.1 unless the actual audio path can handle it.
  4. Force a fresh handshake after changing EDID so the source refreshes its audio choices.
PROBLEM 07

HDCP / COPY-PROTECTION BLACK SCREEN

Menus may work, but protected video becomes black.

  1. First rule out resolution/bandwidth/cable problems using simple non-protected menus and a conservative format.
  2. Check Vertex RX/TX and whether the problem begins only when protected playback starts.
  3. Test source → display and source → AVR/display directly to identify the failing stage.
  4. Only then check the Vertex HDCP setting (HDCP slide: 2.2 Mode / middle Auto-GUI / 1.4; GUI CONFIG → HDCP VERSION). A green side logo means the HDCP handshake is done; do not force HDCP as the first fix.
PROBLEM 08

4K60 DOES NOT WORK

4K24/30 works but 4K50/60 is unstable or black.

  1. This strongly points to the higher-bandwidth path.
  2. Enable the display/AVR Enhanced/UHD HDMI mode for the used input.
  3. Use 600MHz / 18Gbps certified cables, ideally 2–4 m (6–12 ft).
  4. Reduce chroma/bit depth temporarily to prove bandwidth is the issue.
  5. Remember original Vertex tops out at the HDMI 2.0-class 18Gbps / 600MHz signal range.
PROBLEM 09

SECOND DISPLAY HAS NO PICTURE

One output works; adding the second sink breaks one or both.

  1. Test each display alone first and note its supported resolution/HDR/audio capability.
  2. Reconnect both only after each individual path is known-good.
  3. Use Automix when the source must see a capability set suitable for both displays.
  4. If one display is 4K and the other 1080p, introduce Vertex scaling deliberately.
  5. Add the AVR only after the two-display behavior is understood.
PROBLEM 10

AVR CAUSES BLACK SCREEN

Source → Vertex → display works; inserting the AVR breaks video.

  1. Set the AVR HDMI input to its full 4K Enhanced/UHD signal mode where applicable.
  2. Test Vertex → AVR → display with a conservative 4K/SDR format first.
  3. Then prove HDR10 before Dolby Vision/LLDV.
  4. Check both HDMI cables around the AVR.
  5. If RX at Vertex is correct, focus on AVR capability, AVR input format and downstream handshake.
