Frequently Asked Questions - DVI-PROWALL-4X Avenview

How do I set up the DVI-PROWALL-4X video wall processor?

Connect your source device (e.g., digital signage player) to the DVI/HDMI input. Connect up to four displays to the DVI/HDMI outputs. Then connect the 12V 5A power supply and turn on the unit. Install the control software from the included CD or website, and connect via USB or Ethernet for configuration.

What control methods are available?

You can control the processor via IR remote control, front panel buttons, USB virtual COM from a PC, or Ethernet (using IP control software). The software provides full layout and adjustment options.

What resolutions and layouts are supported?

The processor supports input and output resolutions from 640x480 up to 1920x1200@60Hz (WUXGA) and 1080p. Predefined layouts include 1x1, 1x3, 1x4, 2x2, and mosaic. Custom layouts can be configured via the software.

How do I perform EDID learning?

EDID learning is used if video/audio issues occur. Using the control software, you can force the unit to learn the EDID from one of the connected displays or from one of six built-in EDID profiles. This ensures compatibility across all displays.

Can I rotate the display orientation?

Yes, the DVI-PROWALL-4X supports rotation. The IR remote includes buttons for VW3x1 (+90°), VW3x1 (-90°), VW4x1 (+90°), and VW4x1 (-90°). The software also allows mixed portrait and landscape configurations.

What is the warranty period and coverage?

Avenview provides a 3-year warranty from the date of original retail purchase. It covers defects in materials and workmanship. Labor and parts are free during the warranty period. Proof of purchase and product registration are required. Damage from misuse, unauthorized repair, or accidents is not covered.

How do I update the firmware?

Firmware can be updated via USB or Ethernet connection using the control software. Download the latest firmware from Avenview's website and follow the instructions in the manual. Ensure the unit stays powered during the update to avoid corruption.

What cables are recommended for best performance?

For video input and output, use high-quality DVI or HDMI cables. For Ethernet control, use solid CAT6 cables with T568B termination for long distances. Shielded STP cables can reduce interference. The manual provides a performance guide for different cable types.

Can I use this processor with HDMI sources and DVI displays?

Yes, the inputs and outputs support both DVI and HDMI signals. Adapters may be needed for physical connections. Audio is only supported when using an HDMI source device. The processor handles signal conversion seamlessly.

How do I restore factory settings?

In the control software, go to the 'Factory Reset' option under the settings menu. Click the button to reset, wait about 10 seconds, and then restart the unit. This will erase all custom configurations and return to default.

EDID LEARNING

The EDID learning function is only necessary whenever the user/installer encounter problems with video/audio from the DVI/HDMI output port. HDMI sources and displays may have various levels of capability in playing audio and displaying video. The source will output the most common standard audio format and video resolutions to the connected HDMI displays. Example a 720p stereo HDMI signal output is the best choice when having audio or video problems. The user can force the DVI-PROWALL-4X to learn the EDID from the standard or common HDMI display within the set of 4 to ensure all displays are compatible to display the HDMI signals normally.

EDID Learning as below:

Software Control: Please refer to the Operation Approach\ Method B: Software Control

There are six embedded default EDIDs formats in this device, please see below,

I. Full-HD(1080p@60)-24bit 2D & 2ch
2. Full-HD(1080p@60)-24bit 2D & 7.1ch

NOTE

The QUALITY and TRANSMISSION of the video signals depends on the characteristics and quality of the UTP cables. Higher resolutions and longer transmission distances require low skew cables (<25ns/up to 300m) for best performance.

Unshielded CAT6 with metal RJ-45 connectors is recommended.

NOTICE

1. All HDMI over UTP transmission distances are measured using Belden CAT6A (625MHz), 4-Pair, U/UTP-Unshielded, Riser-CMR, Premise Horizontal Cable, 23 AWG Solid Bare Copper Conductors, Polyolefin Insulation, Patented Double-H spline, Ripcord, PVC Jacket using Quantum980 signal HDMI Video Generator Module Video Pattern Testing.
2. The transmission length is largely affected by the type of category cables, also the type of HDMI sources, and the type of HDMI display. The testing result shows solid UTP cables (usually in the form of 300m or 1000ft bulk cable) can transmit a lot longer signals than stranded UTP cables (usually in the form of patch cords). Shielded STP connectors are better suit than unshielded UTP connectors. A solid UTP CAT5e cable shows longer transmission length than stranded STP CAT6 cable. For long extension users, solid cables are your only choice.
3. EIA/TIA-568-B termination (T568B) for category cables is recommended for better performance.
4. To reduce the interference among the unshielded twisted pairs of wires in category cable, you can use shielded STP cables with shielded connector to improve EMI problems, which occurs in long transmission.
5. Because the quality of the category cables has the major effects in how long transmission distance will be made and how good is the received display, the actual transmission length is subject to your category cables. For resolution greater than 1080i or 1280x1024, a solid CAT6 cable is the only viable choice.
