NovaLCT functions for calibration and servicing
Pixel-level brightness and chroma calibration helps align the appearance of the display. NovaLCT can set a startup image and images for Ethernet-disconnected or no-video conditions, and detect card temperature, voltage, cable communication status and video-source status.
Configuration information and firmware-version readback are documented for NovaLCT V5.0.0 or later. The card also supports NovaStar’s general 5-pin LCD module for temperature, voltage, single operating time and total operating time.
Connection diagrams
The V1.0.0 manual describes a synchronous system displaying a connected computer’s images and text. It includes both sending-card and no-sending-card arrangements. These diagrams show the documented connection modes; they do not make the MRV328 a standalone media player.

Frequently Asked Questions
Is the NovaStar MRV328 still available?
No. This listing identifies the MRV328 as discontinued and no longer available. The specifications and diagrams are retained for existing systems.
How many HUB75 connectors and pixels does one MRV328 support?
The V1.0.0 product description states eight standard HUB75 connectors and a maximum load of 256 × 256 pixels per card.
Can the MRV328 work without a sending card?
The linked V1.0.0 manual includes a no-sending-card connection diagram using a computer. This remains a synchronous computer-connected arrangement, not independent media playback. Check the required software and configuration for the existing system.
Can I read back the configuration and firmware version?
Yes. The manual specifies configuration-information and firmware-version readback in NovaLCT V5.0.0 or later. Save the existing configuration information before servicing the installation.
What should I compare when sourcing an MRV328 replacement?
Check the exact card revision, eight-port HUB75 layout, module driver IC, scan settings, pinout, power requirements and saved configuration. A matching connector count or pixel capacity alone does not confirm compatibility.
