Zitat: With the widest range of inputs among the pico projectors in the 100-lumen category, Optoma´s PK320 gives its owner a great deal of versatility at a modest price. Its 16:9 native aspect ratio is terrific for watching movies without interpolation required, and both data and video quality are very good as long as image size is kept under 40 inches. Video looks good even at larger image sizes, but data images suffer from some image fuzziness. There are lower cost pico projectors on the market, but the PK320 is the only one with both a digital input and a 100-lumen capability.
