Liquid-crystal display for on-set monitoring — acceptable color accuracy for live camera feed. Standard for focus pulling and external recording.
On set, you need a reliable screen that shows you the camera output in real-time — without delay, without color chaos. The LCD monitor does exactly that: a flat liquid crystal display that connects to your camera via HDMI or SDI and immediately shows you what the sensor is capturing. This is essential for focus pullers — you see the depth of field, the contours, whether the actor's eyes are sharp. Without a monitor, you're working blind.
The process is simple: plug in the HDMI cable, connect the monitor, done. Most modern cameras have HDMI output; older ones use SDI. The LCD monitor needs to boot up quickly — if the first shot is already loading and the monitor is still starting up, you'll lose precious time. Contrast and brightness are your first adjustment points. In direct sunlight, you'll struggle: many LCD displays reflect terribly. Here, a professional small-format monitor pays off — better viewing angles, fewer reflections. Inexpensive consumer monitors are fine to start with, but the color reproduction is mediocre and the brightness is nowhere near sufficient.
A critical point: latency. Cheap LCD monitors often have a 50–100 ms delay — that sounds like nothing, but it's noticeable during pans or fast camera movements. Professional field monitors keep latency below 30 ms. Color calibration also matters — if you're working on an uncalibrated monitor, the exposure on set will look different than it will later in the edit. Many gaffers and DPs therefore rely on 4K HDR monitors that can also correctly display Log footage.
Practical tip: Use a monitor arm or rig it onto your Steadicam's rig pole — otherwise, you'll be holding the thing for 14 hours and your arms will fall off. Protect the monitor from dust and water; on location, this piece of equipment is exposed to brutal conditions. And always: double-check that the cable is securely connected. Nothing is worse than a monitor that loses its connection mid-shot.
