LCD monitors attached to Steadicam rigs have limited use for focus pulling itself due to low resolution and poor outdoor visibility, but can provide valuable framing reference for assistants.
Focus pulling on Steadicam depends primarily on anticipation, intuition, and timing rather than screen monitoring, making the monitor a supplementary tool rather than a primary control method.
Small handheld monitors can help focus assistants understand shot composition and anticipate timing changes, particularly useful when blocked from direct sight of actors.
Frame size references learned through experience (e.g., where the frame cuts at chest, belt, or thighs for specific distances) allow focus assistants to maintain accurate pulling even when temporarily blocked from viewing.
The risk of becoming overly dependent on a small monitor screen exists, as operators naturally focus their attention where they look, potentially missing real-time action and timing cues.
Iris control capability for HD work, separate from focus, can be useful for operators who need independent control while mobile.

LCD monitor resolution limitations make actual focus pulling from screen impractical
Monitor usefulness varies significantly between individual focus assistants based on personal working style
Outdoor lighting conditions severely limit small LCD monitor visibility
