TU4K Pro Android LED Playback and Control
The NovaStar TU4K Pro combines an Android media player, LED sending functions and video processing in one unit. It supports up to 13 million pixels with image scaling, or 8.8 million pixels in pixel-to-pixel mode. HDMI sources, locally stored content and wireless screen mirroring can be used for conference rooms, corporate showrooms and auditoriums.
For system planning, distinguish the LED screen load from media decoding resolution: support for an 8K video file does not mean that the processor can drive a full 8K screen pixel for pixel.

Playback, Inputs and Screen Control
Two HDMI 2.0 inputs accept signals up to 4096 × 2160 at 60 Hz, while the HDMI 1.3 input accepts up to 1920 × 1080 at 60 Hz. The Android 13 platform includes 8 GB RAM and 128 GB storage. ViPlex Handy supports program editing and publishing, and wireless mirroring supports Windows, macOS, iOS and Android devices.
The 20 Gigabit Ethernet outputs connect to the LED display. OPT 1 carries the data for Ethernet ports 1–10, and OPT 2 carries ports 11–20. These optical outputs are primary outputs and cannot form an Ethernet loop backup; optical modules are purchased separately.

Specification Version and Installation Notes
The original downloadable specification below is V1.0.1, dated February 20, 2025. The playback figures in this table follow NovaStar V1.2.0, dated October 31, 2025. The older document lists three 4K or seven 1080p videos, while V1.2.0 lists two 4K or five 1080p videos. Check the firmware and applicable documentation before designing a multi-video layout.
The verified specification lists HDMI video inputs; it does not establish the earlier page claims of a 12G-SDI input or Google service certification. Confirm any requirement for those features against the exact hardware before ordering. Whiteboard activation and compatible wireless screen-mirroring dongles are separate purchases.


Frequently Asked Questions
How many pixels can the TU4K Pro control?
It supports up to 13 million pixels with scaling, or 8.8 million pixels in pixel-to-pixel mode. Maximum width and height are 16,384 and 8,192 pixels respectively, subject to the total pixel load.
Can the TU4K Pro play 8K video?
Yes, within the decoding limits in V1.2.0: one 7680 × 4320 video using H.265/HEVC at up to 24 Hz and 14 Mbps, or VP9 at up to 30 Hz and 51 Mbps. This is a file-decoding capability, not a full 8K pixel-to-pixel LED loading rating.
Can I mirror a laptop or phone to the LED screen?
Wireless mirroring supports Windows, macOS, iOS and Android, up to 3840 × 2160 at 30 Hz. The default split-screen arrangement supports nine mirrored screens. Compatible wireless dongles are optional accessories.
Can the two optical ports provide loop backup?
No. The specification identifies both as primary optical outputs and states that they cannot be used for Ethernet loop backup. OPT 1 maps to Ethernet ports 1–10 and OPT 2 maps to ports 11–20.
Are optical modules and whiteboard activation included?
The specification lists optical modules and whiteboard activation as separate purchases. Confirm the supplied accessories and required software activation when selecting the system.
