An Asus monitor, that has a contrast ratio of 1000:1, and next to it, it says (ASCR 20000:1), what does ASCR mean, and is 20000:1 a good contrast ratio?
It is a method of dynamic contrast ratio and it means absolutely nothing.
Hell even the typical contrast ratio of 1000:1 might not be right and doesn't tell you anything. All the contrast ratio is is a ratio of how much brighter the white point is than the black point.
It does not tell you anything about what the white point or the black point is. You could have a monitor with a really high contrast ratio compared to another monitor and it wouldn't indicate how dark the blacks would be or how white the whites are going to look.
Some manufacturers, especially for dynamic contrast levels will use the difference between the black level at the lowest brightness level with the white level at the highest brightness level which skews everything even more.
You best bet is to try and find a review that measures these things using out of the box settings as well as adjusted ones.
Someone can correct me if I have posted anything incorrect.
------------------------------I'm a git, deal with it.
aspect to ratio is the way the monitor increases the resolution while keeping its ratio, (for a 1920x1200, its ratio would be 16x10), aspect to ratio is like a way of enlarging the image but not stretching it out
Aspect ratio is the difference in horizontal and vertical sizes, nothing more. An image does not increase in size as the resolution increases, quite the opposite as anything on a monitor is of a fixed amount of pixels and will indeed get smaller with an increase in resolution unless the object being displayed itself increase in size which take more pixels.
Maintaing aspect ratio in image scaling is different, that is as you say enlarging something proportionally.

I think what you are trying to say is you want a monitor that has 1:1 image scalling, as S/S is saying. But then again if you are buying a monitor then you would run at native res anyway, wouldnt you ? which kinda makes scaling not that relevant i would have said.
Anyway as 505090 said there really is no substitute for actually looking at monitors in stores to physically see what they look like, Buy some specialist magazines and read reviews of models you like the look of and at first just ignore what the numbers say and read what the reviewers have reported.
I read a magazine about Hi Def Equipment every now and then and its surprising how often the one the reviewer picks from the group test isnt the one with the best tech spec. Its the one that gives the best real world experiance. Mactronix
He explains the different modes of video scaling, heres the one i meant
c) Fill to Aspect Ratio:
In this mode, none native resolution video will be stretched vertically and horizontally to fill the screen while keeping the aspect ratio unchanged.
This is the mode that you want to have if you intend to display non-native resolution video.
Before you purchase any widescreen monitor, make sure it can do video scaling for non-native resoution while keeping the same aspect ratio
Well that is wrong in itself as maintain aspect ratio, fill to panel size and 1:1 mapping are the three common scaling options.
Unless the original image of source of video is in the same aspect ratio you cannot expand something to fill the screen whilst maintainging aspect ratio, with most non native images or video you will be left with some black borders in full screen mode at least.
However, both fill panel and maintain aspect ratio except in some cases will result in image quaility loss, 1:1 is the only one that doesn't but also suffers from reduced window or image size.

Scaling is mostly a mote point with computers as you video card should be set to the monitors native resolution.
