The image on my LCD seems to jitter. How can I fix it?
In an LCD, each pixel corresponds to a specific set of red, green, and blue LCD cells. When an LCD monitor gets an analog signal, it has to decide which cell is supposed to display a specific pixel. If it can't make up its mind, the pixel will jump back and forth between adjacent sets of cells, creating an annoying jitter in the display. LCDs have built-in controls to minimize or eliminate the problem:
Look for an "automatic" adjustment feature that will eliminate the jitter, and adjust image size and position at the same time. The feature may be available as a button on the control panel (often labeled Auto) or as a choice in the on-screen display (OSD).
If the monitor does not have an automatic adjustment feature, or the feature doesn't stop the jitter completely, you'll have to adjust the settings manually. Start by adjusting the coarse timing for the LCD, which should be an available setting in the onscreen display (OSD). Typical names for this feature are Clock and Tuning. Increase or decrease the setting until you have minimized the jitter you see in the image. Next, you may also adjust the fine timing for the LCD. Typical names for this adjustment are Phase and Fine Tuning.
