Masterlu: I dont think I was correct in assuming that you have the latest Lumagen radiance..do you?
I ask because I just looked into their product line and realized that they havent released a new product for nearly 2 years and if you have an older Vision HDQ then I STRONGLY urge you to STOP and return that unit.
First off, the Vision HDQ has DVI ports that require HDMI to DVI adapters but, more importantly the chipset and algorithms in the VHDQ cannot hold a candle to whats in the Crystallio or for what Lumagen will be releasing shortly.
In Lumagens defense, I think the new Radiance has the potential to be the single best video scaler out but, there are a few concerns..
1. It has been in production since 2005 and even the beta units have not yet been released, so no promises as to if or when the radiances will ship.
2. What looks good on paper doesnt all manifest itself to look good on the screen. All the latest chipsets and algorithms sound fine and dandy but, sometimes the GUI and actual product doesnt deliver the goods as we would hope.
3. BUGS BUGS BUGS! There is not a video scaler in the world that hasnt shipped with bugs, that goes for Faroudja, Crystallio and DVDO who are constantly updating firmeware. Initially, after the first units roll out and real users have the opportunity to put it into real life systems, you get the lions share of the bug reports. Hopefully, they are minor and can be firmware repaired but, other times it is HARDWARE related and a redesign or replacement is required.
My suggestion for you is to wait for the radiance and ask your dealer if you can use the current lumagen in your system until the radiance ships and/or if he will allow a full credit of the VHDQ towards the new Radiance.
If he will not do that, I strongly suggest you look into the Crystallio, if for nothing else, to compare it to the Lumagen. It has the Gennum chipset and has been out for over 6 months with a dozen firmware updates under its belt and currently pretty solid overall, dare I say the best available today.
