<SPAN class=normal>When tecChannel
recently reviewed the Parhelia, they compared it against cards from a bevy of manufacturers in terms of analog VGA signal quality. Most importantly, tecChannel used instruments to capture the waveforms produced by each card. I'll post links below to their result pages. You'll have to click through to get their full-sized waveform pics.
On the whole, it appears Radeon and GeForce4 cards are reasonably similar in their signal outputs. They are not identical, but close. As with anything, there are exceptions where one particular card is significantly worse or better than the others. There is also the matter of price. On average, a Ti 4600 performs better than the lower-priced cards. That's one of those little hobgoblins we all hate.
The Matrox cards have superior output, at least in part. The G550 puts out a solid signal (especially considering its low price), but it's rivaled by some of the better ATI and NVIDIA implementations. The Parhelia, on the other hand, is very impressive. Its waveform looks almost pristine.
To help illustrate the differences between the various cards, I recommend using the Parhelia signal image as the reference. The closer a card is to matching the shape, height, and width of the Parhelia signal, the bettter the image quality of the card. Also, notice that the RGB signals of the cards are defined as colored lines. Ideally, these lines should stay tight together; keep an eye out for colors that sag or spike. Here are the results for the various cards:
