Marshall Electronics ML-454-V3 Quad 4.5 Inch Rackmount Monitor, HDMI and 3G-SDI

The ML-454-V3 packs four independent 4.41-inch LCD panels into a 2RU rack chassis, each fed by its own looping 3G/HD/SD-SDI and HDMI input so a control room, routing room or fly-pack can monitor four sources from one slot. Loop-through outputs on both video formats let a signal pass on to a recorder or downstream monitor without a separate splitter.

Each panel supports SD, HD and 3G-SDI natively plus 4K over HDMI, with on-screen three-color tallies and embedded audio monitoring per channel. At 400 cd/m2 brightness and a full 19-inch rack width, it's built for always-on monitoring positions.
