I am so happy about this I had to post. After working with Lumagen on this for some time, I got to try their new FW yesterday for 817x1920 @ 72 Hz. My impressions were really good so they went ahead and gave it a general release yesterday evening. The new FW seems to work perfectly at extracting 24 Hz from 60 Hz sources, and for tripling 24 Hz to 72 Hz.

The Radiance processors I feel give the best image I have ever seen on my G90 especially at 72 Hz. But until yesterday, the Radiance had troubles with falling out of film mode when running 72 and the screen would start tearing. Because of this, I have been stuck at 60 Hz since the Radiance was released... Well not anymore!

Also, another Radiance tip for 9" Marquee and 9" Sony CRTs... The Radiance has a full CMS and can fully correct primary and secondary colors. However, I don't generally like the way a digital CMS works with a CRT. That being said, the 9" Sony and Marquee projectors have a supper duper over saturated red primary. What I generally do with a Radiance on these CRT's is to partially correct the red primary. This brings in the red a little bit without applying full correction, and I think it looks absolutely fantastic this way.

To partially correct the red primary go into the CMS menu and then go into the CMS matrix. On the red, reduce the red from 1024 to 1015 and add between 60~75 of blue. This will bring red a bit closer to reference without sacrificing image punch. And those numbers should apply to all 9" Marquee and Sony projectors.

After you do it, all the colors will feel more natural and seem clearer.

$5k and it will only do 817p at 72hz?

I just built a $200 HTPC that is running a 24" CRT monitor right now at 1080p 72hz.

(And yes you can crop your Gamut on a PC too.)

One day Mark I'll have to send you $200+ so I can compare how your HTPC's handle 72Hz compared to my VP50Pro which also does 1080p72

The Pro does a better job of it than my Radiance, but I haven't tried the newest firmware and I only have the XD not the XE.

I'm familiar with a VP-50 and I thought it was a nice piece of kit.

It was nowhere near $5k. I think it cost Moggy about A$2k or thereabouts.

So about A$2.5k for a BD player and VP-50....but you still can't build a media library...SNIF.

This is the CRT projector forum. It's for cheapskates.

The highend forum is the $20k+ forum on AVS. It's for guys like Cineramax.

I dunno.. for me the HTPC would be just another source in my HT. To play my media library ie. all content I can't buy on HDM

At the moment I'm streaming from my computer to a popcorn hour, but if I could build a HTPC, that would eliminate the need for networking issues and file streaming compatibilities etc...

I really dislike that whole stigma of CRT is for cheapskates. Yeh, it certainly can be great bang for buck, but that certainly wasn't the case for me. To me, CRT was about chasing the best possible image, blacks, motion, colours, naturalness blah blah blah, regardless of cost.

I don't mind, call me what you will.

I really, really don't understand the high end market.

I can design speakers (I've done it for money for two Aussie manufacturers). I know high end audio is a crock, I know the bits that go into many high end speakers, and I know what they are roughly worth. There is a middle ground where you get the quality, without the wank factor.

Same goes with projectors. I've seen a G90 and a VP50 and various other kit.

HD does not look any better on a processor compared to a PC (if the PC is setup properly, which is half the fun). The VP has an advantage in smooth playback, that's painful but possible on a PC. But most of you guys use 60hz (Gino you run 72hz don't you?), so the VP advantage is moot.

And don't start me on cars.

I've been using HTPC's for years and have always been a fan of them but for 99% of people I'd always recommend a "black box" solution. The RadianceXD is currently "the" best black box solution.

You can't sell something to masses and expect people to have a degree in computer science to run it.

I've been using PCs / HTPCs all my life that frankly, I'm sick of them. There's no more 'fun' left.
