Resolutions

[jsmoke]

I assume LCD's are still based on a pixel system like CRT's?

If so what is the difference, in terms of data sent, between resolutions, for example, 360p vs 720p. Is it a case of more pixel information is sent the higher the res, and if so, for lower res are certain pixel's info just ignorned by the monitor?

Probably could have exained this better.

It's CRTs which actually lacked any fixed pixels.
That was also behind why their picture could never be as sharp as that of LCDs which use fixed pixels.

Because of fixed pixels LCDs always need image interpolated/scaled to their native resolution, which again makes non-native resolution easily lot softer looking than native resolution.
Unlike CRTs which had similar sharpness also at lower resolutions.
Though if used image resolution has half size in pixels then it can be scaled simply by doubling single pixel in input image to 2x2 pixels on display without image becoming softer.


Here's good tables for what kind data rates various resolutions and refresh rates require:

Ok but lets say a monitors max resolution is 1600x1400, so you have 1600 pixels wide max and 1400 pixels height max. Now lets say you watch a YT video at 720p, that's 1280x720 which is obvioulsy less than the max res the monitor can display, so my questions is do certain pixels just get sent no information if the resolution is set to lower than the max the monitor can display, i.e they are left blank, but because say every second pixel is coloured you don't fully notice it, it just creates a blur effect in the overal picture due to missed pixels?

So for say a full res of 1600x1400 you would have every pixel given information(RGBA) such as
---------
---------

and for lower res' you would have
- - - - - -
- - - - - -
- - - - - -

sort of thing?
