Troubleshooting
No Signal on a Specific Output
- Verify the output card is fully seated in the chassis slot. Remove and reseat if necessary.
- Confirm the correct input is routed to that output via the web GUI or RS-232.
- Check the HDMI or CATx cable. Test with a short known-good cable to isolate.
- Verify EDID is assigned to the input. An unresolved EDID prevents the source from outputting video.
- For CATx outputs: confirm the FLEX-CATRX receiver is connected and PoC is enabled on the FLEX-CAT12OUT port.
Card Not Detected by Chassis
- Power down the chassis before installing or removing cards.
- Reseat the card firmly — confirm the card edge connector is fully engaged.
- Check the web GUI device map. If the card does not appear after reboot, try a different slot.
- Verify the card is a supported FLEX series card. Third-party cards are not compatible.
HDCP Handshake Failure / Purple Screen
- Confirm the display supports HDCP 2.2 for 4K protected content.
- Disable HDCP on the output if the display is a non-HDCP monitor used for non-protected content.
- Check the HDCP compliance mode in the web GUI — set to match the source/display requirements.
4K60 Signal Dropping to Lower Resolution
- The source is reading the display’s EDID and downscaling. Override the EDID on the input card to present a 4K60 EDID to the source.
- For CATx outputs: verify CAT6a cable is used for 4K60 at distances over 40m. CAT5e may cause signal degradation.
- Verify the HDMI cable supports 18Gbps (HDMI 2.0 rated).
Video Wall Layout Not Displaying Correctly
- Confirm each decoder/output is assigned to the correct grid position in the video wall configuration.
- Verify bezel compensation values match the physical display bezel measurements.
- Power cycle all displays after changing video wall configuration.
CATx Receiver Not Powering Up (PoC)
- Confirm PoC (Power over CATx) is enabled on the FLEX-CAT12OUT port in the web GUI.
- Verify the cable run is within 100m and uses CAT6a.
- Check that the receiver is a FLEX-CATRX — third-party HDBaseT receivers are not PoC-compatible with this system.
FAQ
Can I mix HDMI and CATx output cards in the same chassis?
Yes. The FLEX chassis supports any combination of FLEX-HDMI8IN input cards, FLEX-HDMI12OUT and FLEX-CAT12OUT output cards in any slots, up to the chassis I/O capacity.
Can I expand the chassis capacity after purchase?
Yes. The FLEX-MF8X10 chassis starts at 8×10 and scales to 24×60 by adding input and output cards. No new chassis is required as you grow — just add cards to available slots.
Does the FLEX Matrix require an external controller for video wall?
No. Video wall processing is built into the FLEX chassis. The web GUI provides full video wall configuration without requiring an external processor or controller.
Is the FLEX Matrix TAA compliant?
Yes. See TAA Compliance: Flex Matrix Series for details.
What is the maximum cable run for CATx outputs?
100m using CAT6a with the FLEX-CATRX receiver. CAT5e is supported up to approximately 70m at 1080p; 4K60 requires CAT6a.
Can multiple video walls run simultaneously on one chassis?
Yes. Multiple independent video wall zones can be configured on a single chassis, limited by total output card count.
What control interfaces are supported?
Web GUI (browser-based), RS-232, TCP/IP, and UDP. Crestron, AMX, Savant, and Control4 integration via RS-232 or IP.
