View Full Version : 2560x1600: Is there a need for AA?

11-13-06, 11:25 AM
For those of you with monitors (Dell 3007)that can handle 2560x1600 resolution, is there a need for antialiasing at that resolution? Even though the 8800 series can handle AA at that resolution can you actually see a difference or is the power of the 8800 better put to using HDR and AF at maximum settings?

Of course there is a need. 2560x1600 although is a high resolution, you are stretching it across a 30" display.

of course, doesn't matter what size of the screen or resolution AA and AF is always needed

Well I guess you wouldn't need AA on a 2'' screen @ 2560x1600. :D But yeah, I agree with Jakup on this one, big screens need higher resolutions to come close to the image quality of smaller ones, which makes the 30'' on par with 20'' @ 1680x1050. And because you need AA on those, you'll also need it on the 30incher. :)

So at higher resolutions the jaggies are smaller but with bigger screens the jaggies are bigger? So they somewhat cancel eachother out.

The problem is how noticeable the stepping break in the line is. You will always have a stepping of lines, so AA will always give you better quality. It's more a question of what your eyes will tolerate and how important it is to the game you are playing. So, if you have poor vision then maybe it won't be as noticable ;-) I suppose the no-aa resolution would be one that there are enough pixels to exceed the resolution in the current field of vision. For me, I have 20/12 vision, so I'm stuck with AA for the forseeable future.

definitly needed !!!

AS the dot inch stay nearly same. (0.25 or 0.29mm) the need of AA STAY SAME.
on a 22" CRT , in 2000x1536, i think it's not needed. but LCD dual / tripple view and 30" HAVE SAME DPI.

Yeah, AA will also help hide some of the seams.

Resolution really has nothing to do with the perceived effects AA.
The more important factors are: Pixel Pitch and Viewing Distance

(i.e. a 47in 1080p monitor is 1920x1080, but it will look extremely blocky if you sit in close)
