Couple of Questions.


1.) Are there drivers for the ATI radeon and PowerStrip that support custom resolutions and timings for DILA projectors??


2.) Have any of you guys tried the 1080i output with a Radeon on your DILA?


Thx,


Cameron

Cameron,


There are detailed answers to proper Radeon drivers, and supporting custom resolutions with Powerstrip in the Home Computer forum. You will get tons of specific info there.


I've tried both 1080i and 1080p with the Radeon and my D-ILA.

The picture quality is very good, but scaled DVDs look best scaled to the native 1360 X 1024 and 1360 X 768 panel resolution.

Really?


I have heard such great things about how the DILA manipulates a 1080i signal I figured that if the PC scaled it up that much that it might bridge the gap a little between DVD and HD like some of the folks on the HTPC forums were saying.


BTW. I have the PowerStrip 3 beta that I received in February or so. Do I need a more current version to work with a Radeon card or will the newer ATI drivers be suficient??


Thanks,


Cameron

Cameron,


The latest recommended version of Pstrip is 164.


As per Ashley, I downloaded the 7140 drivers for my VE which arrived today. I think there's even a newer one now, but Ashley confirmed that the 7140s will do 1360 x 1024, 768 & 580 thru Pstrip.

Cool,


Thanks guys. I think that I might just have to make a purchase here.

I have been considering getting a Radeon for my D-ILA, too. One thing that makes me nervous is all the talk on the HTPC forum about tweaking the gamma on the Radeon. I suppose it's a good thing that you can do that, but, on the other hand, I have a D-ILA that's already calibrated, and I'm wondering if the gamma output by the Radeon would match what my projector expects.

It's a good thing tomorrow's a holiday, cause' I think I'll be spending most of it getting the VE work like I expect it to. http://www.avsforum.com/ubb/frown.gif


Over the last several months I've been saving all Radeon/DILA/custom res threads. Hopefully it'll be a little easier process now than when they first came out.


Dave, it seems that the gamma is now easily adjustable to where I don't think it'll be a problem for your calibrated DILA.

Chris:


But, what do you adjust it to? My D-ILA was calibrated using a Geforce HTPC, so I guess I'd want the Radeon's Gamma set to mirror the output of the Geforce? Are those numbers known?

Cameron,


Yes, the D-ILA's internal scaler does do a great job with 1080i input, but then you have two processes, one is scaling the 720 X 480i to 1920 X 1080i, and then the internal scaler downconverts it to 1360 X 1024/768p.

As opposed to having the HTPC just scale it straight to 1360 X 1024/768p.


Secondly, the 1080i/p image is obviously not pixel matched. This doesn't show up with true HD 1080i, but you can see it with computer input, especially with text. I've done a fair amount of back-to-back resolution switching, and the picture is just clearer with the DVDs scaled to native panel resolution.


I spent a great deal of time trying to get the ATI payer working, but it was never reliable, and WinDVD looks excellent. I also had my G15 calibrated and the picture looks great with rich colors without fiddling with Gamma controls.


I've had the VE card as well for a couple months, but since the drivers didn't support the color overlay it was useless. But it appears that the new drivers support native resolutions, so I'll try them out.


I can only try these tweaks in spurts because I'm actually watching movies most of the time. But I do try and keep up with the posts to see if any of the tweakers have found solutions to existing technical problems.

Dean,


I see your point. So what are some of the other known Radeon issues?


Also, what OS are you running it on?


Thx,


Cameron
