Built into a hard case, the Lilliput BM280-4KS Carry-On 4K Broadcast Monitor (V-Mount) is a 28" native UHD 4K monitor with a V-mount battery plate, useful for both studio and field situations. The full capacity of the 3840 x 2160 UHD resolution 8-bit panel can be driven at up to 30 fps by any of the three HDMI 1.4 inputs, via one HDMI 2.0 input with up to DCI 4K sources, or via SDI input with up to 1080p60 sources.

In addition to the four HDMI inputs available on the back panel, HD and SD sources include one 3G-SDI, one DVI, and one VGA port, and there is one loop-through SDI output. Video signals input via any of these ports will be properly scaled to fit the entire screen. Analogue audio from the RCA inputs or embedded digital audio from video inputs can be heard using the monitor's built-in speakers or the 3.5mm headphone output. There is a tally input, and a DB-9 tally adapter is included to utilise tally information on the monitor. The monitor also supports adjustable HDR colour spaces and you can choose built-in presets or load custom 3D LUTs via its USB port.

For power, this monitor accepts a wide range of voltages ranging from 12 to 24 VDC. In the studio, the included power supply plugs the BM280-4KS into the wall, and the 75/100mm VESA mount can be utilised for mounting on a stand. The included tally connector passes tally information through to the monitor when connected to a switcher. While in the field, the monitor will accept battery power via the built-in V-mount plate. It can stand up vertically using the rubber feet built into the monitor's hard case, and a sunshade is included for increased visibility outdoors.


HDR and 3D LUTs

When HDR is activated, the display reproduces a greater dynamic range of luminosity, allowing for colours and lighter and darker details to be displayed more clearly. You can use preset Logs or load your own custom LUTs via the USB port.

Assignable Buttons

Using the four assignable buttons on the front panel, you can quickly turn any four essential monitoring tools on and off without venturing into the monitor's menu system.

Carry-On Enclosure

The included hard case/enclosure improves the robustness of the monitor's metal chassis, useful when venturing outside controlled environments. A rear opening gives easy access to all the monitor's ports and accessory mounts.

Supports Wireless HDMI (WHDI) Technology

With a separately available WHDI receiver, the BM280-4KS can accept wireless HDMI signals up to 1080p60 from up to 164' away for a hassle-free cordless connection. With the WHDI system in place, one transmitter can broadcast to multiple receivers, so no splitter is required for multi-monitor viewing.
