You know not of what you speak - do some research before trolling. All LCDs change their image at a specific rate, usually 60 cycles per second with newer models at 120 cycles. Your idea of picture quality is rather narrow, as LCDs excel only in sharpness and brightness. They are inferior to a quality CRT for color rendition, contrast, viewing angles, response times, and the ability to display differing screen resolutions. Admittedly, my point is somewhat moot, as quality CRTs are as rare as hen's teeth these days (new ones, anyway).
He has a point. Refresh rate on an LCD operates a bit differently than refresh rate on a CRT monitor. Yes, it's how often the image is updated, but the manner in which the image is updated can play a big role, and LCDs update much differently from CRTs. Also, only modern LCDs excel at brightness. LCDs always used to have a reputation for being dim. Thankfully, those days are largely behind us (except in cheap laptops). Further, LCDs are extremely sharp at their native resolution, but when they are displaying a non-optimal resolution LCD image quality often appears blurry compared to other screens.
I would say that watching non-HD video on an LCD HD screen, for example, is a somewhat disappointing experience. This includes, of course, classic video games.
