The QUAD VIEWER Series is the latest addition to Marshall's line of IMD-equipped monitors. The QV241-HDSDI 24" Quad Viewer features a full resolution 1920 x 1200 LCD panel, built-in high quality HD Quad Splitter, four independent HD-SDI inputs, one DVI-I input, IMD (In-Monitor Display) capability, Audio Presence indicator, and Time Code. Video and DVI-I both offer full screen mode, while quad-split mode is scaled to fit onscreen in the highest resolution. IMD and Tally are supported via manual mode, along with Image Video, NVISION, MEI (Marshall), and TSL protocols. Other features include Closed-Caption presence display, two front panel user-configurable function buttons, RS-422/485 port with pass-through, and field-upgradeable firmware.

Marshall's IMD monitors are a cost-effective "all-in-one" solution for post production houses, broadcasters, and mobile units. This fully-integrated approach eliminates the need for additional or separate Under Monitor Displays and allows UMD information and tallies to be displayed directly within a Marshall flat panel monitor, while saving precious rack space. These new monitors also offer our RotoMenu™ feature which allows fast, direct, and easy menu navigation. This 6RU unit also ships ready to rack mount and can be wall or ceiling mounted with an optional VESA adapter.


Allows viewing of 4 inputs on the screen at once. Each input source is scaled and positioned in real-time so that all 4 inputs can be seen. Besides the standard Quad layout, there are 3 other layouts (including Full Screen) to choose from:
