Iiyama today announced a new lineup of touch sensitive monitors for desktop computers. The offerings consist of the 15" ProLite T1530SR, the T1730SR, and the T1930SR, all of which connect either through VGA or DVI, and support USB and RS-232 for the touchscreen interface. The new ProLite screens use a 4:3 aspect ratio and come in either a black or white bezel. The 15-inch model supports a typical 1024x768, featuring a 16ms response time, while the 17- and 19-inch versions are rated at 5ms response, with a resolution of 1280x1024. Contrast ratio for the displays is measured at 500:1 for the 15-inch, and 800:1 for the larger models. Iiyama is selling the ProLite touch-based monitors for £330 (~$700US), £350 (~$750US) and £400 (~$850US) respectively. The touch-LCDs are advertised as being compatible with both Macintosh and Windows-based systems.
