3 questions on resolution/dpi - plz answer any you can!

I built a media center PC. I was running it at 1920x1080. I could not read anything from my couch, so I bumped up the DPI to 150% (which I must assume is 144 dpi). Everything looks fine now. I need to know how the driver handles this though. Am I rendering everything in 1280x720 but Windows scales it updwards? Or am I really running true 1920x1080 but seeing larger buttons?? The reason I am asking is I am using this to play Blu Ray and I want full 1080p out of it, not 720p. So is Blu Ray affected by this DPI setting or not?

Next, I had significant overscan on the TV. I used NVidia's control panel to shrink the image down to fit, but now it says I'm running 1840x1020 (or something like that). Is it not possible for me to shrink my image so that it fits on the screen without changing resolutions? (Again I paid for and want 1920x1080 and nothing less).

Lastly, 1080p is supposed to be 1920x1080 right?! So when I purchase a blu ray disc that says 1080p, what resolution is it? (Seems simple but bear with me). Blu Ray movies come in 2.35x1 ratio, not 16x9. So it can't be 1920x1080 unless the video included the back bars as well. So is the video 2538x1080? Or am I watching a 1920x817 movie?

Thanks for any help on any one of these!
