horizontal-hold control
television
Quick Summary
The horizontal-hold control on a television adjusts the horizontal deflection generator to synchronize with the horizontal synchronizing impulses. This ensures the scanning spot at the receiver precisely matches the transmitter's horizontal retracing. Essentially, it helps maintain a stable, side-to-side picture alignment. Other common controls include channel selection, fine-tuning, contrast, brightness, and vertical-hold, each contributing to the viewer's ability to adjust picture quality.1
