NovaStar MRV208 LED Receiving Card | 8 HUB75E Outputs
$ 13.40
The NovaStar MRV208 is an LED receiving card with 8 HUB75E connectors and up to 16 groups of parallel RGB data. A single card supports up to 256 × 256 pixels at 60 Hz.
The MRV416 and MRV412 references retained below concern separate models that this listing identifies as discontinued.
NovaStar MRV208 LED Receiving Card
The MRV208 receives display data for LED modules through 8 HUB75E connectors, supporting up to 16 groups of parallel RGB data. Its rated resolution is 256 × 256 pixels at 60 Hz. Pixel-level brightness and chroma calibration, cabinet mapping and communication monitoring support setup and maintenance of an LED video wall.
This page is for the MRV208. The MRV416 and MRV412 images and download links are retained as model references; the original listing identifies those two models as discontinued and unavailable.

Setup, Calibration and Troubleshooting
Use mapping to display receiving-card numbers and Ethernet-port information on the cabinets. Temperature and voltage can be monitored without extra peripherals. Bit-error detection and firmware readback require NovaLCT V5.2.0 or later according to the specification.
Calibration works with the NovaStar calibration system. Dark or bright lines at module and cabinet boundaries can be adjusted separately. For 3D output, the sending card must also support 3D; the receiving card alone does not establish a complete 3D system.
Before replacing a card, check its exact model and revision, module pinout, driver IC, scan configuration, mounting arrangement and saved cabinet configuration. Similar HUB connectors do not establish automatic interchangeability.
MRV208, MRV412 and MRV416: Model Reference
The separate manufacturer specifications give the following capacities. The older page values of 256 × 226 for MRV412 and 512 × 256 for MRV416 conflict with their retained V1.0.2 PDFs; the documented limits and software conditions are shown here.
| Model | HUB75E / RGB groups | Documented loading capacity |
|---|---|---|
| MRV208 | 8 / 16 | 256 × 256 at 60 Hz |
| MRV412 | 12 / 24 | Up to 512 × 512; NovaLCT V5.3.1 or later |
| MRV416 | 16 / 32 | PWM IC: 512 × 384; common IC: 384 × 384; NovaLCT V5.3.0 or later |

Frequently Asked Questions
What resolution does one MRV208 support?
The MRV208 V1.0.2 specification lists a maximum of 256 × 256 pixels at 60 Hz. This rating is for MRV208, not the separately named MRV208-1 or MRV208-N.
How many HUB75E connectors does the MRV208 have?
It has 8 HUB75E connectors and supports up to 16 groups of parallel RGB data. Check the module pinout and cabinet configuration before connecting modules.
Can the MRV208 replace an MRV412 or MRV416 directly?
Do not assume a direct replacement. Their connector counts, RGB data groups and loading capacities differ. Check the exact receiving-card revision, module wiring, driver IC, scan configuration and cabinet settings.
Does MRV208 support brightness and color calibration?
Yes. It supports pixel-level brightness and chroma calibration with the NovaStar calibration system, plus adjustment of dark or bright lines between modules or cabinets.
Are the existing PDF downloads for MRV208?
No. The two retained downloads are MRV416 and MRV412 specifications. Their model names and limits are shown separately so they are not mistaken for MRV208 documentation.
