Marshall V-R842DP-AFHD Dual 8.4in Rackmount HD SD Broadcast Monitor 4RU

Marshall V-R842DP-AFHD Dual 8.4in Rackmount HD SD Broadcast Monitor 4RU

The Marshall V-R842DP-AFHD is a dual-screen rackmount LCD monitor designed for broadcast and professional video production environments. It houses two 8.4-inch 2.4-megapixel TFT screens in a 4RU chassis that fits a standard 19-inch EIA equipment rack. Each screen accepts and displays all SMPTE/ITU HD and SD video standards with fully digital signal processing. Note: this unit requires an external power supply that is not included.

Applications

The V-R842DP-AFHD is used in broadcast control rooms, production trucks, edit suites, and on-set video village setups where two independent video feeds need to be monitored side-by-side in a compact rack footprint. The dual-screen design allows a director or video engineer to compare two sources simultaneously — for example, monitoring a live SDI feed on one screen and a VGA confidence feed on the other — without requiring two separate rack positions. Marshall Electronics built this unit to meet broadcast-grade signal requirements, accepting the full range of SD and HD formats under SMPTE and ITU standards, making it compatible with both legacy SD broadcast infrastructure and HD production workflows. The 4RU chassis keeps rack space usage low in tight mobile or truck-based production environments. Units like this remain in active use at smaller broadcast facilities, post-production houses, and in A/V integration applications where reliable multi-format monitoring in a single rack unit is needed.
