Anaheim, California (August 3, 2026) - Extron announces the DTP3 T 321 4K/60 USB-C DTP3 Transmitter. The new DTP3 T 321 simplifies long-distance USB-C extension, sending video, audio, data, power, and bidirectional RS-232 signals up to 330 feet (100 meters) over a single shielded CAT 6A cable. The transmitter features a USB-C input, local HDMI output, and two USB device ports. It supports video resolutions up to 4K/60 with 4:4:4 color sampling, EDID Minder®, and HDCP 2.3.
