If potential TV buyers ever found out how great projectors are, panel manufacturers would be in a heap of trouble. Nine times out of 10, projectors are easy to setup, come with a built-in, decent-sounding speaker and produce a picture that's just as sharp as their LED counterparts at twice the size. There's a tenth time, though, where the shoddy speaker, the temperamental picture and the inconvenient setup ? not to mention the hefty price tag ? make those $250 720p, LED HDTVs pretty appealing. Which group does Optoma's latest 1080p, $1,399 (about £870, AU$1,600) gaming projector fall into? I'll give you a hint: It's not the first one.DesignThe GT1080 is a sleek, all-white behemoth, measuring in at 12.4 x 4.0 x 8.8-inches (or 315 x 102 x 224 mm, W x H x D). It's designed for close quarters gaming and should be placed, at least what I gleaned from my testing, about four to five feet from the wall.In the front, a bulbous lens dominates the panel. Horizontal vents located the left of the lens keep the unit itself cool, but generate an awful lot of heat. Spin it all the way around to the right and you'll find a plethora of ports ? everything from an MHL-enabled HDMI port to mini-USB.It's not a comprehensive package of every port you'll ever need (there are no DVI or VGA ports, for example).
