Standard definition video output from a monitor is insufficient for focus pulling because the image resolution is already reduced through letterboxing or pillarboxing and further compressed by SD limitations, making it difficult to identify sharp focus on a small display.
Commercial 2.4 GHz wireless systems sold at general retailers tend to experience signal dropout during use, making them unreliable for critical video monitoring tasks.
Wireless HDMI is expected to become a viable alternative for video assist once the technology is miniaturized to a practical size.

Discussion is from 2010, before widespread adoption of modern wireless video standards.
Participants did not fully resolve whether affordable wireless solutions could be made practical for focus pulling work.
No specific technical measurements or quantitative data provided for resolution limitations.
