Does a refresh rate apply to flat panels as it does to CRT's? Are they the same for panels & CRT's, do they differ in any way?

Emory and Cheeky Kid - RE: LCD refresh rate. Refresh rate doesn't apply to LCD at all. For CRT, an electron beam is scanned from the top to the bottom to "refresh" the image. The # of the "refresh" in a second is the refresh rate of the CRT monitor. In LCD, the image is composed of the liquid crystal and each crystal is controlled by a thin-film-transistors (for TFT models only). So there is really no top-down scanning going on, thus no refresh rate isue. I think the 60Hz is only refer to the video card. A side-note: While refresh rate doesn't apply to LCD, there is a response time associate with the LCD. Passive Matrix (eg. DSTN...) has a slower response time than Active Matrix (eg. TFT) and tends to produce a ghost image for fast moving motion. So for desktop solution, I wouldn't recommend a passive matrix LCD. aC
