What This Product Does
The CSV‑7400 is a DisplayPort™ Multi‑Stream Transport (MST) hub designed to expand a single DisplayPort™ output into up to four independent DisplayPort™ displays.
It allows extended or mirrored multi‑monitor configurations from one DisplayPort™ source and is intended for professional multi‑screen environments.
Important Display Capability Notice
The CSV‑7400 supports DisplayPort™ 1.4 input and uses MST to distribute video signals.
Supported display configuration:
- Up to 4 independent displays, each up to 4K@30Hz
The hub can also support higher single‑display resolutions (such as 8K@30Hz), depending on host configuration and available bandwidth.
Actual resolution, refresh rate, and color format depend on:
- Host GPU capabilities
- DisplayPort™ bandwidth provided by the source
- Operating system MST support
The MST hub does not convert, scale, or enhance video signals.
DisplayPort™ MST Requirements
- A graphics card that supports DisplayPort™ MST
- An operating system that supports extended MST desktops
Windows systems support MST for extended desktops.
Other operating systems may mirror displays instead of extending them.
Video Format and Protection Support
- Supports RGB and YCbCr color formats
(4:4:4 / 4:2:2 / 4:2:0) - Supports 8‑bit, 10‑bit, and 12‑bit color depth
- Supports HDCP 1.4 and HDCP 2.2 for protected content playback
Power Requirement and Stability
The CSV‑7400 includes a Micro‑USB power input for enhanced stability.
- Recommended power input: 5 V / 2.4 A (12 W)
- External power is recommended when using multiple displays or high resolutions
Using external power ensures stable signal distribution across all outputs.

Common Questions
Does this hub support four independent displays?
Yes. Up to four displays can be operated independently, subject to host GPU and OS support.
Does the hub increase my computer’s display capability?
No. Display performance is determined by the host system.
Is external power required?
External power is strongly recommended for stable quad‑display operation.
Can this be used for video walls or trading setups?
Yes. The CSV‑7400 is suitable for professional multi‑display environments such as trading floors, control rooms, and productivity workstations.
In case you have any problems with obtaining the correct images on your displays, please disconnect the Power cable for 20 seconds and then reconnect. The unit should be resetting itself.
