Get to know this product.

The Atlona AT-HDVS-150-TX-PSK is a 3×1 switcher and HDBaseT transmitter with two HDMI inputs and a VGA input with audio. Video signals up to 1080p, plus embedded audio can be transmitted up to 230 feet (70 meters), and up to 130 feet (40 meters) for 4K/UHD video @ 60 Hz with 4:2:0 chroma subsampling. The HDVS-150-TX-PSK is identical to the AT-HDVS-150-TX, with the addition of local powering capability and an external power supply. This makes it ideal for extending AV directly to a projector with an HDBaseT input. The HDVS-150-TX-PSK can serve as the central component of a compact, automated AV system with the convenience of automatic input selection.

Compact Switcher and Extender

The HDVS-150-TX-PSK combines the benefits of auto-switching and the advantages of HDBaseT signal transmission. It incorporates many popular integration convenience features while delivering excellent value for classrooms, huddle rooms, and meeting spaces. Surface mounting brackets are provided with the HDVS-150-TX-PSK for easy under-table, furniture, or on-wall installation.


The HDVS-150-TX-PSK automatically selects an input source based on detection of the 5 volt hot plug detect (HPD) signal.

Automatic Display Control

When used in conjunction with the AT-HDVS-150-RX receiver, the HDVS-150-TX-PSK can provide control to a display through RS-232, without the need for a separate control system. This simplifies system design and integration while reducing costs. With automatic display control, the HDVS-150-TX-PSK can trigger a display to power on automatically whenever a laptop or other device is connected. At the end of the presentation, when the presenter disconnects the laptop, the HDVS-150-TX-PSK forces the display to power off. Ease of presenter interaction with the system, and the savings incurred by automatic display shutdown provide a significant return on investment. A power button on the front panel can be used for manual on/off control of the display.


  • Simple yet complete AV systems with HDBaseT-equipped projectors and flat-panel displays
  • Installations in which HDVS-150 Series transmitters are to be used with third-party HDBaseT devices

Product Compatibility

The AT-HDVS-150-TX-PSK is ideal for extending AV and control to a display with an HDBaseT input.


Also available from Atlona is the AT-OME-ST31, for applications requiring 4K/UHD compatibility. The OME-ST31 offers three-input switching for HDMI and USB-C sources, mirrored HDBaseT and HDMI outputs for driving two displays, and selectable 4K downscaling to 1080p for the HDMI output.

3×1 HDBaseT switcher

  • Features two HDMI inputs plus a VGA input with audio
  • Allows advanced HDMI display devices to be used with legacy VGA sources
  • * Audio signals will not pass without an accompanying video signal

Local AC powered version of AT-HDVS-150-TX

  • Includes external power supply – ideal for point-to-point installations with an HDBaseT-equipped projector
  • Also can be powered via PoE (IEEE 802.3af Powered Device – PD) – provides an additional powering option from the HDVS-150-RX receiver, or the optional AT-PS-POE power injector

Long distance HDBaseT extension

  • Transmits AV up to 230 feet (70 meters) @ 1080p or 130 feet (40 meters) @ 4K/UHD using CAT6a/7 cable
