Can your display properly show HDR-10? I’d so curious what you see comparing that scene from Into Darkness (Enterprise rising from the ocean) - Dolby Vision vs HDR10 video output on the ATV4K....

Display as in the OLED? I can try that scene both ways (DV vs HDR10) and let you know how it looks. I have that movie in my library so easy to test. I will try and get to it this weekend and report back.

I am thinking about getting a 4440 unit, but have a couple of questions. Does the pro unit support Dolby vision? Can this unit be upgraded to 4446 by adding new inputs later?

No Dolby Vision support and I think Jim posted a few months back that is not on the roadmap.

but yes you can add more modules to make it a 4442 or a 4444 or a 4446

Picked up an Apple TV 4K. Seems to work pretty solid with the Pro! SJ

Some Displays already have their own way to analyze frames and dynamically modify tone mapping (for example LG and even this years Sony projectors have some kind of dynamic enhancement).
I'm quite happy with the current state of IM compared to the original implementation. But I also think, this frame analysis would be a major step to improve the HDR experience, provided that the Radiance has enough processing power and the result wouldn't look like a bad tuned dynamic iris.

Question: how does 4k streaming on the Apple TV through the Lumagen compare to a 4k disc? Also, does it contain the same metadata that allows the Lumagen to determine the nit mastering level (for IM purposes)? I know that Apple recently revamped their encoding, and I'm wondering if they're getting closer to disc quality. I'm looking for a reason to move my Roku Ultra from the theater into the family room.

It is OK, but disc (and in my case Kaleidescape as well) are superior including audio. We mostly used streaming to watch Netflix original content as well as others like HBO, etc. I also create movies and slide shows from my Mac and easy to show these through the Apple TV devices. Now, if they would finally add Amazon to these units which they are suppose to do soon.... Also, haven’t watched any HDR yet.... SJ

For me, 4K HDR appears identical to UHD. Outstanding....

4K Dolby Vision titles (relying on HDR-10 base layer information) seems to have some meta data or encoding issues resulting in occasional highlight blowout - working with Apple on investigating this, and I think Jim and Patrick are starting to look into what’s being delivered and how the Radiance is processing, so it’s a bit early to know what’s going on

But once this is addressed, and Atmos is added, it will be a killer box.

I just want to give Jim Peterson of Lumagen a shout out for the best support I have ever received for any product from any vendor. I was one of the first 40 owners of a Radiance Pro and mine has logged many hours of use. My unit basically stopped working recently and I sent it in for repair. Jim went well above and beyond what I expected to get my Pro working and he treated me extremely well. I am a Lumagen fan for life.

I echo your experience with Jim. I bought an Radiance XD in 2007, am still using it but will be upgrading to a pro next week (tuesday) along with a new JVC RS640. I am the farthest from understanding all this as a person could get and Jim, both 10yrs ago and now has patiently helped me. This level of customer service is unheard of. I will tell you, that if I could not buy from Jim, I will do without and just run my new JVC as is and without a external processor.
