Troubleshooting & FAQ: Flex Matrix
No Signal on an Output Verify the output card is fully seated in the chassis slot — remove and re-seat if uncertain. Confirm the source is active and…
Overview
Each output on the FLEX-MF24X36 scales independently. You can set each output’s resolution on its own, whatever the source sends and whatever the other outputs are doing. One chassis can feed 4K displays, 1080p screens and a WUXGA projector together, with no separate scalers. The chassis carries up to 3840×2160 at 60Hz 4:4:4 (8-bit).
Per-Output Scaling
Set output resolution from the front panel or by command.
- Front panel: on the 7-inch touchscreen, open I/O Config. Choose the scaler timing, then one or more output numbers, then press Enter.
- ASCII command (RS-232 or TCP/IP): “s hdmi y scaler z!”, where y is the output (0 = all outputs) and z is the timing index below. For example, “s hdmi 0 scaler 9!” sets every output to 1080p60.
- Type B command: “*255OSOxxxHxx!”. For example, “*255OSO001H01!” sets output 1 to Auto.
Which output resolutions can each output be set to?
Each output takes Auto or one of 15 fixed timings. The scaler command, the Type B commands, the video wall “time” parameter and quad view all use these index numbers.
| Index | Output timing |
|---|---|
| 01 | Auto |
| 02 | 480p60 |
| 03 | 576p50 |
| 04 | 720p50 |
| 05 | 720p59 |
| 06 | 720p60 |
| 07 | 1080p50 |
| 08 | 1080p59 |
| 09 | 1080p60 |
| 10 | 4K30 |
| 11 | 4K50 |
| 12 | 4K59 |
| 13 | 4K60 |
| 14 | 1024×768@60 |
| 15 | 1280×1024@60 |
| 16 | 1920×1200@60 |
Before relying on Auto (01), connect the display and confirm the resolution the output delivers. A video wall takes its output timing from the “time” parameter (2–16) when it is created, and quad view uses the same index.
Confirm 480p60, 576p50 and the 59 Hz timings on the unit, with the display connected, before a design depends on them.
Can an output drive a 1280×800 (WXGA) projector at its native resolution?
Not with a fixed timing, because 1280×800 is not in the list. Test Auto with the projector connected on site. If Auto does not give a usable picture, choose a listed timing that the projector’s own documentation says it accepts. A WUXGA (1920×1200) projector matches timing 16 directly.
Picture Adjustments per Output
- Contrast, brightness, saturation and hue: “s hdmi y con z!”, “s hdmi y bri z!”, “s hdmi y sat z!” and “s hdmi y hue z!”, each 0–255 with a default of 128.
- Output stream off or on: “s hdmi y stream z!” (0 = disable, 1 = enable).
- Normal, freeze or black (Type B): “*255OVOxxxMxx!” with M00 = normal, M01 = freeze, M02 = black.
EDID Management
EDID is the data a display sends a source to describe the resolutions and audio formats it supports. On the FLEX-MF24X36, EDID is set per input. If an output shows no video, set the input’s EDID to match the display’s native resolution.
How do I set the EDID on an input?
- Front panel: in the EDID menu, pick a stored internal EDID or an EDID copied from a connected display, then press Enter to save.
- Web GUI (default IP 192.168.1.72): on the EDID page, choose the EDID for each input from the list and click Load. Refresh reads back the current EDID information.
- Command: “s edid in x from z!” sets input x to EDID z. “r edid in x!” reads it back, and x = 0 returns all inputs. Confirm the command on inputs 17–24 before relying on it.
| EDID index (z) | EDID presented to the source |
|---|---|
| 1 | 1080p, stereo |
| 2 | 1080p, 5.1 |
| 3 | 1080p, 7.1 |
| 10 | 4K30 4:4:4, stereo |
| 11 | 4K30 4:4:4, 5.1 |
| 12 | 4K30 4:4:4, 7.1 |
| 16 | 4K60 4:4:4, stereo |
| 17 | 4K60 4:4:4, 5.1 |
| 18 | 4K60 4:4:4, 7.1 |
| 19 | 4K60 4:4:4, stereo, HDR |
| 24–39 | Copy from HDMI output 1–16 |
Use the indexes in this table. If you set any other value, read the input back with “r edid in x!” and confirm the EDID it presents before relying on it.
Which EDID should an HDR source get?
Use index 19 (4K60 4:4:4, stereo, HDR). It is the only HDR preset in the table: presets 17 and 18 (4K60 4:4:4 with 5.1 or 7.1) are not HDR presets. For HDR with multichannel audio, copy the EDID of an HDR display on HDMI outputs 1–16 whose EDID also lists the multichannel formats you need, then check the result with “r edid in x!”. Presets 24–39 copy the EDID from HDMI outputs 1–16; for an HDR display on any other output, use index 19. Test the result on site.
Setup Checks
- If an output has no video, check that the output card is fully seated and the input card LEDs show an active source. For a CAT output, check that the FLEX-CATRX receiver is powered and connected. Then set the input’s EDID to match the display’s native resolution.
- Video walls and quad views must start on a card’s 1st, 5th or 9th output port.
- The chassis supports up to 30 independent video wall zones, each up to 4×3 (12 displays), with bezel compensation.
Use Case: Mixed Display Environment
A large venue running the FLEX-MF24X36 could set up its zones like this:
- Bar TVs (1080p): outputs set to timing 09, 1080p60.
- Main feature video wall (4K displays): a wall created with time 13 (4K60), starting on a card’s 1st, 5th or 9th port.
- Projector (WUXGA, 1920×1200): output set to timing 16, 1920×1200@60.
- Operator monitors (1080p): timing 09 on each output, or one monitor in quad view at timing 09 to watch four sources on one screen.
All of these run from the same chassis and the same sources. CAT output zones use FLEX-CATRX receivers.
