Having spent some time with a Lumis and a C3X1080 on the same screen, I would have to say the difference is significant. Those who have done the same agree.
1.The brightness difference is major.
2.The CR difference is huge.
3.The black level difference is night and day.
4.The ANSI CR is certainly noticeable.
5.The connectivity is massively better (if you need it).
6.The install flexibility is superior.
Mine was sharper, but that may simply be luck of the draw.
The C3X1080 produces a fine image indeed. The Lumis I used was simply the best image I have ever seen.
Hope this helps.
I don't own a Lumis, but I spent some time with one recently.
2. Disagree. I was disapointed to find the CR wasn't much improved over the C3X1080. In fact, isn't the native CR pretty similar? Everyone is touting the high CR when you measure a checkerboard screen, but that's with DB engaged. When it's not engaged - and remember, it's 'dynamic' the CR looks to be the same as my C3X1080. High contrast isn't just desired when black is on screen. I used a lot of professional test videos that required high contrast to give the picture any sense of depth but did not necessarily involve a lot of black (e.g. close ups of fruit or wine glasses etc) and to my eyes, I was simply seeing native contrast. I've seen these same images many times on both my projector and a higher contrast projector and know the difference.
Now, if resolving the image requires a lot of black (for edges, bumpy textures etc) and there's enough black on screen for DB to be engaged, the Lumis looks smashing. So what I'm trying to point out here is that the Lumis doesn't seem to perform like a projector with high native CR.
3. From what I saw it was definitely improved and I want one myself for that reason.
4. Agreed - at least with DB engaged.
6. You got me on this one, but I'll take your word for it.
Hey, I'm not trying to say the Lumis isn't a good projector - I think it's the best you can probably get for a *huge* image; my earlier post was directed at a screen size of 92"; in my humble opinion you can do better at this size.
