For those with no interest in Home Theater PC's, skip this post.
But, if you're messing around with that, and looking for the best visual quality when scaling to higher resolutions, I'd recommend checking out the Elsa Gladiac GeForce 2. Standard GeForce and GeForce 2 cards are very good, but many users have commented that they appear to have a bit of edge enhancement and ringing- whether this is due to differences in the implementation of the scaling algorithm in the drivers, or differences in the EMI filters used at the DAC outputs, and how they interact with cable runs and projector inputs is not clear. I'm doing some testing and tweaking on a new Elsa Gladiac, and so far I really like what I see- in more than one way. More after this weekend, but so far I think this is a board to look at quite carefully if your'e intersted in DVD playback for high res CRT systems, maybe even for DILA and LCD. Tested so far at 1024X768 and 1280X720.
Another problem observed with many GeForce cards and other video boards is the inability to hit a minimum 100 IRE level. Most GeForce cards peak at 700 mV output, which is the VESA standard, but doesnt reach the nominal minimum 100 IRE level of 750 mV. First checks on my Gladiac show it hitting 730 mV (Tek 200 MHz scope) without any adjustments. Scaling the IRE grayscale accurately for the video overlay is one of the main things that has to be tweaked to get these boards to really sing, unlike the Matrox G400's which seem to be virtually dead on out of the box.
With WINDVD 2.2 build 92, overall performance is very good; on the weekend I'll complete calibration and we'll see how good it is.
