interlaced display 
A cathode-ray tube (CRT) display in which the electron guns skip every other line on their first pass, then fill in those lines on a second pass. This allows for a lower refresh rate at higher resolutions (such as 1,024x768) without producing flicker, but the scheme doesn't work well when displaying animated graphics. Most monitors aren't interlaced, but lower-quality display adapters pushed into high resolutions and high color sometimes do interlace. Opt for a noninterlaced monitor.
