The Chromamaxx 19TCRW 19 Inch Touch Screen is based on the latest 5 Wire Resistive technology. Price performance ratio is ideal for the budget conscious user while quality and specification is certainly not compromised. The display inputs include both Analog and Digital (DVI) with Touch Screen connectivity via either USB or RS-232 which offers greater than typical flexibility. A solid and steady base supports the Touch Screen with an adjustable stand offering full 90 degree angles. Extensive Touch Utilities allow for 4-point calibration. An incredibly powerful Touch solution.
