I see your logic now on the response time. But I doubt that anyone would notice flicker from a 10ms response monitor with any real world video source. Possibly a carefully crafted video signal could produce a noticeable display artifact.

If it takes up to 10 milliseconds (10/1000 of a second) for the screen to get the cells stabilized to show the image that's 60 lots of 1/100 second that the cells may not be stabilized in every second Even at 30fps, with a 10Ms response time, that's still about 1/3 of each second that the image is not stable Depending on the screen's physical properties, and what's being shown, that may not be an evident problem, it may be an almost subliminal problem, or bad enough that the viewer is aware of the flicker effect. Consider - how little (and infrequently) the displayed image of a windows MSWord, or Excel session change. If the signal is changing more quickly than the pixels can respond, then the pixels pretty much do not reproduce the signal at all. That's with a constantly changing image - if the image is mostly static, then the static bits will probably be OK almost certainly on a LCD screen, and probably on a Plasma display. (Plasma energises the cell to generate the light, LCD tend to alter a mask/filter of the backlight) Re 1920x 1080 on a 19" screen - it depends on the number of cells on the 19" screen, and how near you are to the screen - there are many 19" screens that only have 1280 cells in each row of the display and few 'wide aspect' 19", or even 21" screens are more than 1366 x 768 - the poorer 'HDTV' resolution So - yes - on a 19 " screen you would not see the difference The difference (extra clarity and fine detail) becomes apparent when you view it on a screen with a full 1920 x 1080 complement of cells, and an acceptable response time. As I mentioned in earlier threads - I've got a 19" Hansol display that physically does just over 1600 x 1200 ( number of phosphor dot sets on the screen along, and down), but is limited to 1280 x 1024 because the electronics are the same as those for the 17" screen, and only up to that screens capability In other words - at the highest resolutions the Hansol 17" screen gives a better image than the Hansol 19" screen!
