SEETEC monitor T51 （3 x 5"""" 2RU） 3*5 inch

SEETEC T51 – Triple 5" 2RU Rack Monitor with 3G-SDI, HDMI and 3-color Tally

The SEETEC T51 is a slim 2RU rack monitor that houses three 5" LCD screens. It displays SD, HD and 3G‑SDI video and offers multiple inputs and outputs to integrate with broadcast and production systems. You can mount it in a standard 2RU rack to monitor three sources side by side.

Thin, durable rack design for continuous use

The T51 uses a full metal case to provide durability and improved heat dissipation. Because rack monitors often run continuously, SEETEC designed the unit for stability, reliability and electromagnetic compatibility so the whole system operates smoothly when paired with adjacent professional equipment.

Display and panel details

Each of the three screens features a 5" TFT LCD panel with LED backlight. The displays have 800×480 resolution and provide clear monitoring of incoming video signals. The viewing angles support flexible placement: horizontal viewing up to 140° and vertical viewing up to 120°.

Inputs, outputs and audio

The T51 supports a range of broadcast connections per LCD for flexible routing and monitoring. Each screen accepts SDI, HDMI and composite video, offers corresponding outputs, and includes audio connections as well.

• Input: 3G‑SDI × 1, HDMI × 1, CVBS × 1, Audio (L/R) × 2
• Output: 3G‑SDI × 1, HDMI × 1, CVBS × 1
• Audio: Stereo headphone output

Front tally lights and DB‑15 control

The monitor includes front tally lights for each screen. The tally system displays three colors — red, green and yellow — and the lights are controlled through DB‑15 ports on the rear panel. This allows integration with tally systems used in live broadcast environments.
