I don't necessarily agree with the opinions expressed here. The thing is, most of the reason you cannot achieve good black level on your CRT, IMO, is that you run it too hard. You run it too hard because you have too much ambient light level often. The only way you can get rid of the ambient light level is to get your room darker. So its a cycle, either up or down.
In my opnion, you should get your room as dark as possible, and run your CRT no higher than it absolutely should be. This will give you better blacks and longer life on your CRT and better resolution because you are getting a smaller spot size.
Most theaters don't make their walls black probably more due to aesthetic reasons than anything else. I believe that it is absolutely true that it would provide a better image if they did.
Others may disagree, but that's how I feel about it. My Dwin, which is not the most high end CRT in the world and not the best at holding black, does quite well on black level against a background that is (though not black itself) very dark during viewing. Since I control the light level pretty well (at night when I'm doing critical viewing) I can run the projector low enough to get good black level when properly calibrated. And I've found that it increases practical resolution as well. I used to think that 650 lines was about all the Dwin could do on a 16:9 screen, but that was partly due to contrast being higher than it needed to be. Now I'm getting 720 and might be able to squeeze a bit more, because I've got the contrast down, something I could only do by getting the room darker, not lighter.

If it don't have a control port, don't buy it!
