So if you take those lines and blow them up to fill the screen, you would think it would diminish the quality of the image instead of using all the horizontal lines of resolution like 16:9 are using? Please fill me in.
Generally speaking, on a Blu-Ray movie disc, you get the same source resolution whether the movie happens to be 16:9, 1:85:1 or in widescreen 2:35:1 format. So a 2:35:1 letterboxes movie or a movie using the whole 16:9 frame, is still giving the same resolution per any particular portion of the movie image.
If you enlarge (via zooming) EITHER your 16:9 image or your 2;35:1 image, you are enlarging the same resolution, and yes the larger you make the image, the more you will notice any defects in the image, or lack of sharpness. But as long as you are projecting each on the same sized screen, the resolution for each film will be the same.
The issue of the available Blu-Ray resolution (and the resolution/detail in the original image source) can come into play in a Constant Image Height type set up, where you are blowing up your 2:35:1 image much larger than your 16:9 images. Doing so *can* bring out softness or other issues in the movie image and since you aren't zooming out on the 16:9 images, they can look sharper or "better" more consistently.
But it's not because the 16:9 image has "more resolution," it's that you are zooming the image much larger for only ONE type of movie (2:35:1), and not the other.
Personally, I've adopted a Variable Size Image system, which just means I bought the biggest screen I could, added 4 way remote controlled masking, and I zoom the image whatever size I want, depending on the aspect ratio, image quality, or just how I want to watch something at the time. Going really wide for 2:35:1 images can make some of them appear more soft, and with lower contrast. However, on the other hand, it can be amazing with lots of good Blu-Ray transfers just how large I can make the image without suffering substantial drops in image detail and sharpness. Some titles seem like they can just keep going larger and larger, and never appear less sharp.
