Resolution and replacement planning
The supported timing list includes standard and wider computer resolutions, while the active LED area remains subject to the card loading limit. The movable image window and resolution-readback functions help configure the displayed area.
Confirm the exact board revision, power method and required receiving-card setup before installation. The original table does not provide a usable receiving-card cascade count or a supply-voltage rating.
Frequently Asked Questions
What is the pixel capacity of the VCMA7-V20EX?
The listed capacity is 1.3 million pixels per card and 650,000 pixels per network interface. Keep the active LED load within those limits.
Does the card accept DVI video?
Yes. One DVI video input is listed. Confirm the source connection and required resolution before ordering.
Can several sending cards connect to the same PC?
Yes. The description lists USB communication with support for multiple sending cards connected to one computer. Match the configuration software and connection arrangement to the installation.
Are the listed video resolutions also LED loading capacities?
No. The supported video timing list and the 1.3-million-pixel LED load describe different limits. A source resolution in the list does not mean the card can drive that entire pixel area.
Can I use VCMA7-V20EX instead of VCMA7-V20?
Replacement compatibility is not established by this listing. Compare the full model suffix, hardware revision, power connection and display configuration before substitution. The original text mentions three power methods without specifying them, so verify the correct wiring before use.
