Yeah, I'm going to post this and unfollow the thread because these can turn fast.
Lumagen and MadVR are the two that keep coming up because they're the two major players, if not the only players. They are, in my opinion, an essential tool for projector owners.
I own a Lumagen, and am also biased as such. Neither are inexpensive, but looking at the product lifetime and amortizing the cost, I think the Lumagen is the much better value.
- MadVR
- offers a couple features listed above that the Lumagen does not and likely won't do
- is essentially a PC running software
- Lumagen
- offers a product life cycle that is unheard of in this hobby, the Lumagen Radiance Pro was released over 10 years ago and continues to receive feature updates for free via firmware updates
- the new Lumagen model is due around end of year, which is being designed as a new platform of the future for the product
- is a custom built appliance built on FPGAs instead of off the shelf PC hardware
I bought my Lumagen to add dynamic tone mapping to my previous projector that didn't offer it. What I realized is that it offers a ton more functionality for my theater than DTM. As a user with a 2.40:1 screen, the auto aspect ratio detection and control is essential now that I've experienced it. No more imperfect lens memory adjustments, waiting for the lens to settle in. It's now instant. And so much more, but those are the huge features.
Both systems provide more granular calibration capabilities than those built in to projectors and other displays. The MadVR goes deeper on this, Lumagen claims to stop where the human eye can perceive the increase in precision.
Anyway, if you have a projector, especially if you have a scope screen, you should dive much deeper in to the features of each and select the one that matches your needs.
