Built for travel and location work, the Lilliput 12.5" 4K Broadcast Director Monitor with SDI, HDR & 3D LUTS in Hard Case is a portable self-contained monitor solution with a wealth of features suited to broadcast productions. Enclosed in a protective case, the monitor's 3840 x 2160 LCD panel is built into the lid, with the V-mount battery plate and inputs/outputs located in the base, and with all connections protected from dust, water, and damage during transport and storage. The case lid has two pistons that protect the built-in panel by preventing the lid from being jerked open or accidentally slammed shut. The monitor has 3G-SDI input and output supporting 1080p60, two HDMI 2.0 inputs that support 4K60, and two HDMI 1.4b inputs that support 4K30. The monitor also supports VGA and DVI inputs. Video signals inputted via any of these ports will be properly scaled to fit the entire screen. The USB port is used to load LUTs into the monitor, while analog audio from the RCA inputs or embedded digital audio from video inputs can be heard using the monitor's built-in speakers or via the 3.5mm headphone output. There is a tally input, and a DB-9 tally adapter is included to utilize tally information on the monitor. The monitor also supports adjustable HDR color spaces, and you can choose built-in presets or load custom 3D LUTs via its USB port. For power, this monitor accepts a V-mount battery (not included), and it has a built-in coaxial power input that accepts 10 to 24 VDC.

HDR and 3D LUTs

Selection Buttons

Below the battery slot are dedicated input select buttons with menu and navigation buttons.

Accessory Mounting

An accessory mounting bar is mounted on the right side of the case exterior, allowing you to attach accessories such as a wireless video receiver to the case.


The monitor features a V-mount for use of batteries, and it also has both a 10 to 24V power input and a 12V power output connector.
