You will hate yourself if you use the 3800 and the Da-Lite HP together in a completely dark HT. In another thread right now I'm discussing a very similar issue with the 3800 and a white 110" screen. The 3800 measures 1200 lumens in its dimmest setting. The Da-Lite is HP is a 2.8 gain screen, right? If you are in that narrow cone that it is actually 2.8 gain then the 3800 will pump out.....78fL. 🤯
Dude, that's just insane.
No way no how would I use the Da-Lite HP with the 3800. If you are down with selling it and getting a grey screen then I think you should entertain the 3800. It isn't really a dark room projector for screens of this size. It's black levels are too high because of how bright it is. If you slap that thing in there right now, even with a 1.0 gain screen, you will most likely think the dark scenes are washed out.
Now the 5050 and the Da-Lite HP is an interesting proposition. The 5050 can get pretty bright itself but it has a manual iris that you can really throttle down and control the light. This subsequently increases contrast. With such a high gain screen you could theoretically use the 5050 in Eco and use the manual iris as well, resulting in really good black levels/contrast. Not only does this allow you to keep your existing screen, it will maximize the abilities of the 5050. You could easily use the color filter for HDR as well which a lot of people can't because they need more lumens to light up their screen.
So, just with these factors you are looking at replacing the screen to get the best out of the 3800 for your room. Or, using your existing screen and maximizing the 5050 with it.
Not only this but the 5050 is sharper, doesn't have focus uniformity issues, and has a lot better color gamut coverage. I also have a hard time justifying the 2x cost increase from the 3800 to the 5050 but in your case I really think it is the right choice since you have a dedicated dark theater. Just to be clear though, how do you define dark basement HT? Do you have dark colored walls, ceiling, and floor?
