TB20 Plus for LED Signage Playback and Control
The NovaStar TB20 Plus combines media playback and LED sending in one player for full-color signs. Use HDMI input for a live source, or publish programs for asynchronous playback from internal storage or a USB drive. A computer, phone or tablet can publish content and control the display, with remote publishing and monitoring available through compatible cloud platforms.

Screen Size and HDMI Playback
The ultra-long-screen solution supports a width up to 8192 pixels, but does not increase the 650,000-pixel total load. Maximum width and height are separate limits. The player’s 4K video decoding capability is also separate from its LED output capacity.
HDMI provides the synchronous video source. Full-screen scaling supports downscaling only: the source width and height must each be at least the corresponding screen dimension, with source dimensions from 64 to 2048 pixels and a maximum of 2048 × 1024 at 60 Hz. Interlaced HDMI input is not supported. Custom HDMI resolutions require changing the preset EDID and a source that supports the custom resolution.
USB, Wireless Publishing and Multi-Screen Timing
USB Type A supports playback, firmware upgrades and storage expansion up to 128 GB. The supported file systems are Ext4 and FAT32; FAT32 has a 4 GB maximum file size. exFAT and FAT16 are not supported.
Wi-Fi AP and Sta can run together, allowing the player to join a Wi-Fi network while retaining its local hotspot. The default hotspot details are on the unit’s label. Network priority is wired Ethernet, Wi-Fi, then 4G. A 4G module is purchased separately.
Multi-screen synchronized playback supports NTP timing, GPS with the specified 4G module, or RF with the specified RF module. Enabling this playback synchronization halves the device’s decoding capability, so allow for that when preparing multi-screen media.

Frequently Asked Questions
Does TB20 Plus support live HDMI and offline playback?
Yes. HDMI input is used in synchronous mode, while asynchronous mode uses the internal media source. USB playback is also supported, and the SWITCH button changes between synchronous and asynchronous modes.
Can TB20 Plus drive an 8192 × 2048 screen?
No. These are separate maximum dimension limits for the ultra-long-screen solution. The total display load must remain within 650,000 pixels.
Can the Wi-Fi hotspot stay on while TB20 Plus joins a router?
Yes. Wi-Fi AP and Wi-Fi Sta can be enabled at the same time. The specification lists 2.4 GHz Wi-Fi.
Is 4G included with TB20 Plus?
No. The TB20 Plus ships without a 4G module. Purchase a compatible module separately when cellular connectivity is required.
Which USB formats and capacity are supported?
The USB 2.0 Type A port supports Ext4 and FAT32, with storage expansion up to 128 GB. FAT32 has a maximum file size of 4 GB; exFAT and FAT16 are not supported.
