We stopped by the huge HiSene display at the opening day of the CES show on Tuesday to check out the Chinese company's UltraHD TV sets. Sporting 3,840x2,160 resolution, the sets included the Ultra-LED XT900 family that will be avaiable in 65-, 84-, and 101-inch sizes. The last one promises to be the largest UHD TV on the market, once it reaches store shelves that is.
