The Lilliput Q31-8K is part of the Lilliput flagship range of monitors designed to handle and process an 8K video input signal. It takes 4x 12G-SDI input feeds via the BNC connectors at the back of the unit, and in compliance with the ST 2082-12 video protocol, combines them to create an 8K 60Hz video signal which it displays on the 3840 x 2160 pixel panel.
With other features such as Rec.709 and DCI-P3 colour space, 3D LUT support, remote control through LAN connection, Multiview and Quad-Split, and an optionally purchased 12G SFP+ connection - the Q31-8K packs massive value monitoring into an easy-to-operate system.
