What are you outputting to exactly? Many CRT sets had 2-5" of over-scan...Which will be super noticeable with a desktop if the graphics system is set to exactly fill the image portion of the signal with the digital image in it's buffers... I rather have the full-screen of my video player fill the signal space exactly and show the over-scan built into the TV SETs I'm watching, than have the signal fill only the screen of one TV set correctly.

When evaluating signal characteristics of digital video devices I always try to variac a CRT set down for under-scan (with no signal) on all sides + corners, then compare to a 4:3 DVD, LD or VHS source to see how well the image of the digital device fills the video portion of the video signal (and sometimes see if the sync/blanking looks decent).

I don't particularly like that TV have over-scan and try to minimize it on regular use sets, but I except it as part of a TV's design....Crappy signal devices that don't properly fill the picture space of a signal do get on my nerves.
Letter box is a double edge sword for me...I want to see the whole image in the format it's creators intended without distortion ~%90 of the time, but there is ~%10 where I miss filling the screen on older sets and want to crop in to 4:3....One thing I like about our Cisco mini cable boxes is that they let me choose proper cropped 4:3 (which is great for older shows with the little 4:3 box in the center/ as it removes the artificial boarder), or 16:9.
