Upscaling on ATI 4000 series cards?

[siliconaudio]

Hi folks,

I'm toying with the idea of getting something like an ATI Radeon HD 4550 to see if hardware upscaling from an SD satellite broadcast to 720p or 1080p is worth doing.

Anyone doing this on one of the new Radeons?

from what i've seen that's just hype...i didn't notice any difference in quality between 3xxx and 4xxx cards... if it's just edge enhancement and noise reduction they're talking about, both have these as well..

actually if you output in 1080p to the monitor you're already doing hardware upscaling by definition, those other things are just meant as a 'pseudo' scaling, trying to use tricks to simulate the actual higher resolution, which is still impossible, leading to occasionally strange artifacts...
i find using very little edge enhancement to none looks best if you have a good tv..otherwise it gets a bit contrasty/oversharp...
still, just my opinion...others may differ..
i just found out something actually, turning on edge enhancement and noise reduction, yet leaving them at '0' gives you this 'upscaling' you're looking for without too much coloration from the filters..you can test by pausing 720xXXX video and looking for jaggies, you won't see them with those filters on,but will when they're off totally[unchecked]..leading to a smoother, pseudo-hi-res looking video
[looks kinda like anti-aliasing without looking too softened]
turns out you also have to have no anti-aliasing and catalyst AI to low or off...[but anisotropic is good cranked up all the way]

what card do you have now? it still might be an upgrade..

Here are two pictures upscaled by ATI HD 4770: (source DVD, deinterlaced and upscaled to 1680x1050 using Cyberlink MPEG2 decoder with DXVA on and VMR9 fullscreen exclusive renderer).

That's pretty impressive! Looking at those images at full size on my 22" monitor here at work, I can't see any jaggies at all.

ATI HD 2600 Pro. It doesn't officially upscale, but as you say, it looks pretty good with smoothing and line enhancement on. I'm just wondering what the 4000 series cards do differently with their official upscaling support?
