NovaStar CMS260 all-in-one LED controller
The NovaStar CMS260 combines video processing and LED sending in one unit. Four Gigabit Ethernet outputs support a total loading capacity of up to 2.6 million pixels. The controller accepts HDMI and 3G-SDI sources, provides two adjustable layers, and supports scaling, cropping and preset recall for LED screen layouts.

NovaStar CMS260 specifications and video connections
| LED output | 4 × Gigabit Ethernet ports |
|---|---|
| Total loading capacity | Up to 2.6 million pixels |
| Screen dimensions | Maximum width: 3,840 pixels; maximum height: 3,840 pixels. These are separate limits; the total pixel capacity still applies. |
| HDMI inputs | 2 × HDMI 1.3; one input includes a loop output |
| SDI connection | 1 × 3G-SDI input with loop output |
| Layers | Two, with adjustable size, position and priority |
| User presets | Up to ten |
| Audio output arrangement | HDMI embedded audio via a compatible multifunction card connected to Ethernet port 1; confirm the card and configuration |
CMS260 HDMI and SDI input compatibility
Match the source format to the input before planning the LED output. The linked CMS260 specification lists these signal limits:
| Input | Supported format and limits |
|---|---|
| HDMI 1.3 | 1920 × 1200 at 60 Hz standard; 3840 × 600 at 60 Hz custom; 600 × 3840 at 60 Hz forced input. Interlaced HDMI is not supported. |
| HDMI color format | 8-bit RGB 4:4:4, YCbCr 4:4:4 or 4:2:2. YCbCr 4:2:0 and 10-bit/12-bit inputs are not supported. |
| 3G-SDI | Up to 1920 × 1080 at 60 Hz, with deinterlacing and loop output. Level B signals are not supported. |
Check the output settings of your laptop, media source, switcher or camera. A matching connector alone does not establish compatibility. For an unusual timing, send the complete resolution, frame rate and color format for review.
What the screen limits mean
The maximum width and height do not describe a 3840 × 3840 LED canvas. Your complete screen must satisfy the total loading limit and the applicable port allocation. Send the actual screen pixel dimensions, cabinet layout and receiving-card models before finalizing a purchase.
The HDMI and SDI paths also have different input-format requirements. Confirm the resolution, frame rate and signal format for each source, particularly when using SDI equipment or a custom HDMI resolution. Input acceptance and output loading should be checked separately.
NovaStar CMS260 features for a configured system
The CMS260 specification lists device, Ethernet-port and input-source backup options; output synchronization; image mosaic with up to four cascaded units; and brightness and color adjustment. These functions depend on the screen design, wiring and configuration. Agree the required operating and backup layout before ordering rather than assuming the headline port count covers every mode.
CMS260 connection overview

CMS260 buying questions
Does the 3,840-pixel width mean it accepts standard 4K video?
No. The output width limit and input signal formats describe different capabilities. A 3840 × 2160 canvas contains 8,294,400 pixels, which exceeds one CMS260 unit’s 2.6-million-pixel loading capacity. Check both the source timing and the complete screen mapping.
Can I take audio directly from any Ethernet output?
No. The specification assigns audio output to Ethernet port 1 and requires a multifunction card to extract it. Include the required audio connection in your configuration request and confirm which accessories are supplied.
What should I send when replacing an existing LED controller?
Send the current controller model, receiving-card models, cabinet pixel dimensions, total screen resolution and a wiring diagram. Include the source formats and any backup arrangement. These details allow the replacement to be checked against the existing system.
Where can I find the CMS260 specification?
Use the specification download below to review the connections and operating limits. Ask EagerLED to confirm that the document matches the hardware revision being supplied before approving your order.
What software is used to control the CMS260?
The manufacturer specification lists LCT software and the front-panel knob and buttons as control options. It also describes LCT with calibration software for pixel-level brightness and chroma calibration. Confirm the software version for your controller and receiving cards.
Prepare a CMS260 configuration check
- Screen pixel width and height, cabinet mapping and receiving-card models.
- HDMI or SDI source formats and the two-layer layout.
- Audio extraction, backup and cascade requirements.
- Supplied hardware revision, required accessories, quantity and destination.
Ask EagerLED for the current CMS260 specification and configuration check. For a smaller loading requirement, review the CMS130 controller; compare the complete inputs and features as well as pixel capacity. You can also browse LED video controllers and LED receiving cards.
