8K60 Output Dual-Port LED Wall Video Collaboration Server PTB8800
The PTB8800 is a video collaboration server for large-format LED video walls, command centers and experience venues. It runs Android 15 on a Rockchip RK3588 ARM octa-core platform with 8 GB DDR5 memory and 64 GB eMMC storage expandable to 128 GB. Two 4K HDMI inputs, one 4K USB-C input and UVC/UAC camera input feed two HDMI outputs and one USB-C output. HDMI OUT1 reaches 7680 x 4320 at 60 Hz for point-to-point pixel mapping, and the dual ports can be stitched into a 7680 x 2160 horizontal or 3840 x 4320 vertical canvas.

Models and Options
PTB8800 with 64 GB eMMC storage, expandable to 128 GB.
Output mode: HDMI OUT1 configured for 8K output, or standard multi-output operation across HDMI OUT1, HDMI OUT2 and USB-C OUT.
Stitching orientation: dual-port horizontal (7680 x 2160) or vertical (3840 x 4320).
Control method: Pad-based control for live events, speaker presentations, program insertion and quick scene switching, or fixed control through RS232, dual RS485, SPI, GPIO, TTL and infrared.
Materials and Structure
The chassis is built in aluminium alloy. The front face carries the status area of the server, while the rear concentrates all connection points: 4K HDMI and USB-C inputs, dual HDMI and USB-C outputs, Gigabit Ethernet, Wi-Fi and the RS232, dual RS485, SPI, GPIO and TTL control ports, so commissioning and service access stay on one side of the rack.
Applications
Suitable for LED video wall manufacturers and AV system integrators, control rooms, command centers, sports venues, large exhibitions, live events, digital signage and corporate experience centers, including large-format display installations and horizontal or vertical stitched walls.
Customization
tranScreen develops and manufactures its products in house and offers both standardized and customized hardware and software for partners with special requirements. Output mode, stitching layout, scene layouts and window compositions can be configured to match a project's screen structure and content plan.
