JVC DT-U31PRO 31" 4K Studio Monitor
The DT-U31PRO is a 31.1-inch multi-interface studio monitor with a native DCI 4K panel at 4096 x 2160, built for grading and critical image evaluation. It covers 100 percent of DCI-P3 and 84 percent of ITU-R BT.2020 and supports HDR signals, giving colorists and shading operators a wide-gamut reference at full 4K resolution.
Connectivity spans a 12G/6G/3G/HD/SD-SDI input, three 3G/HD/SD-SDI inputs, and a 4K 60p HDMI 2.0 input, plus quad-link 3G-SDI in both square-division and 2-sample-interleave. A built-in 3D LUT engine with front-panel USB color-sensor support handles auto-calibration, and a four-screen multiview shows one 4K source alongside three 3G sources, or four 3G sources, with audio and UMD. IP remote control and a future SFP slot round out the interface set.
