Each Touch-it multi-image viewer features a high-resolution 7-inch widescreen LCD touch screen on one side and a full-size target screen on the other. Sources (NTSC or PAL autosensing) are displayed as thumbnails on the touch screen display, with the selected signal displayed on the target screen and simultaneously transmitted to a multi-rate BNC connector output. The front panel incorporates a headphone jack, internal speakers, and internal/external audio monitoring switches, allowing operators to route audio to the line out, internal speakers, or both.
HDMon Family of High Definition Monitors
Wohler's family of high definition color video monitor displays, the HDMon series, enables high-quality monitoring of digital HD-SDI, SD-SDI, or DVI signals; analog composite, component, and RGBHV video; and CGI images up to WUXGA resolution. HDMon systems on display will include the 19-inch HDMon 190, the 9-inch widescreen HDMon-90WS, and the dual 9-inch widescreen HDMon-92WS.
Though the HDMon series is designed primarily for 1080-line HD applications, each monitor provides exceptional noise reduction, motion interpolation, and motion-adaptive processing to ensure crisp, clear display of images, regardless of their native resolution. Operating either as a desktop monitor or installed in a 19-inch-wide rack, these LCD displays offer HD resolution, a choice of 4:3 or 16:9 aspect ratios, user-adjustable scaling, and up to 170 degrees of perfect off-axis viewing without the image and color distortions normally associated with LCD displays. A sleek, lightweight design allows HDMon displays to convert from portable to tabletop solutions without the need for additional hardware. Built-in 100Base T Ethernet and RS232 connections allow the monitors to be configured and controlled remotely via a Windows®-based GUI or by third-party control systems.
