NEC Display Solutions Infrared Multi-Touch Overlay Accessory for the V463 Large-Screen Display OL-V463 Features: Transform your existing V463 large-screen display into an interactive touch screen! While adding minimal depth, the OL-V463 adds protective glass and multi-touch functionality to the already high-performance of the V463 commercial-grade display. This overlay solution is HID compliant with a majority of operating systems so loading extra drivers is unnecessary. A unique design that allows for swipe in and out functionality with Windows 8 makes this overlay solution future-proof with the newest compatibility for operating systems. With the addition of this IR-touch overlay, end-users can experience up to 10 simultaneous points of touch - perfect but not limited to the educational, retail and corporate markets.
