NovaStar TB2-4G HDMI LED Controller and Multimedia Player
The NovaStar TB2-4G combines an LED sender with content playback for screens up to 650,000 pixels. Use its HDMI input for a live external source, or publish content to the player for asynchronous playback. It is designed for commercial signs, shop displays and advertising screens.
HDMI and Stored-Content Playback
HDMI input selects synchronous mode; the internal video source selects asynchronous mode. The player supports manual and scheduled switching, with an HDMI-priority option. In synchronous mode, content can be scaled to the screen under the documented limits: source width from 64 to 2048 pixels, and screen width from 64 pixels up to the original source width.
Standard and Optional 4G Versions
The manufacturer specification covers two versions. The standard TB2-4G includes a 4G module. The TB2-4G (Optional 4G) is supplied without that module by default. Confirm the supplied version and local network compatibility before ordering; the model family name alone does not establish the package configuration.

Frequently Asked Questions
Does every TB2-4G include a 4G module?
No. The manufacturer distinguishes the standard TB2-4G, supplied with a 4G module, from the TB2-4G (Optional 4G), supplied without it by default. Confirm which version is being supplied.
Can the TB2-4G display a live HDMI source?
Yes. Its HDMI 1.3 input is used for synchronous playback. Internal content is used for asynchronous playback, with manual or scheduled switching and an HDMI-priority option.
Can it drive a full 1920 × 1080 LED screen?
No. Its maximum loading capacity is 650,000 pixels. The separate maximum width of 1920 pixels and maximum height of 1080 pixels do not mean it can drive both dimensions at once.
Can I connect the TB2-4G directly to a PC by USB?
Yes. The specification documents a USB Type-B connection for screen configuration and publishing with NovaLCT and ViPlex Express on Windows. The USB 2.0 host port serves USB-drive content import.
How much storage is available for my content?
The TB2-4G has 8 GB of onboard storage, with 4 GB available to users, and 1 GB of operating memory.
