What is this setting for? (plasma tv)

Out of curiosity, can someone tell me what the adjustable "Phase" setting is for on my plasma tv?
Manual doesn't mention it.

The only reference I can find is Dot Phase Adjustment (for a Sony) which only applies to computer input.

Maybe it IS only for computer input. The setting only appeared when I connected the TV to V+ box with HDMI.

It's used with the computer I/P

Clock/phasing for Analog inputs
LCD panels use discrete pixels and ideally should be connected to the image source via a digital interface such as DVI. In an analog video signal from a computer's "VGA connector" the luminance data for one pixel runs into the next in a time continuum. To properly recover the data back into the correct discrete pixels requires accurate synchronisation of a "sampling-clock" in the monitor to the "pixel clock" in the graphics card. Although possible, this can be technically tricky to get right (the VGA output was never designed for this!). Symptoms of incorrect clock/phase settings include blurry or shimmering text, and shimmering on fine crosshatch patterns.The "automatic" adjustment of many LCD monitors is not always successful, and manual tweaking may be needed. It is probably wise to allow the monitor (and PC) to warm up for 5- or 10minutes before running this test.

Didn't understand most of that but many thanks for the info. It's obviously nothing I need to bother about.
