That is normal. 1.85 is not 16:9, it's actually wider than 16:9.


16:9 is 1.78

tried that and it didn't work. Funny thing was I had a problem similar to this one with my 3251d. Begging to suspect the dvd player.

Let me try some more dvds. The title menus are fine thought, but im guessin thats 4:3.


Correction: Normal 16:9 dvds only have a tiny bar on the bottom that is hard to notice at first, but it is still there.

A calibration disc like DVE has a pattern that will tell you if your screen is shifted vertically or horizontally. If the image was shifted up a little bit that could explain what you're seeing. Not saying that's the problem, just one possibility.

You sure about that? An anamorphic 1.85 DVD still has black bars on the top and bottom on my TV. (BTW, I mis-read the original post where the black bar is only on the bottom).


I have a 16:9 TV with zero overscan. On 1.85 anamorphic movies, I need to set the TV to stretch and I have small black bars on the top/bottom.

Are you sure the movies with black bars are anamorphic and not letterboxed? 1:85 anamorphic movies will completely fill your 16x9 display. Look here - http://www.thedigitalbits.com/articl...ic185demo.html

Good Link.


I'm pretty sure that the 1.85 movies do not completely fill the screen. I'll have to double check it tonight with some 1.85 stuff. Most of my DVDs are anamorphic. I own very few non-anamophic stuff.


I think the issue may be that my TV does zero-overscan, so the 1.85 stuff that is slightly wider than 16x9 would have small letterbox bars.

I have a Philips DVP5960. Its set at 16:9, progressive, and 720P.

By definition, 1.85:1 images are wider (or shorter, if you prefer) than 1.78:1 images so they WILL show TINY black bars on the top and bottom of a 16:9 screen. This assumes the image has been acurately scaled (maintaining OAR) to exactly fit the width of the display with no extra zoom/stretch/overscan and a vertically centered image.


The size of these bars depends on the width of your display. For a 40" wide display, the 1.85 image will be 40/1.85 = 21.6" high. For a 40" wide display, the 16:9 (1.78:1) height will be 40/1.78 = 22.5". This leaves a difference of

I just did a test with a 1.85 anamorphic DVD (The Girl Next Door, if you must know). Anyways, when using my progressive scan DVD player, and my TV set to stretch, there were indeed no black bars on the top/bottom.


However, when playing the same DVD on my Macbook hooked up through HDMI, with the TV set at 1080p dot-by-dot, there were very small black bars.


My conclusion is that 1.85 anamorphic DVDs will display letterbox bars (albiet, very small), when the scaling is done properly and the TV has zero overscan. The Macbook fits these criteria.


My DVD Player must have some undefeatable overscan built in to it. I know it's not my TV as for SD material the stretch mode is zero-overscan. I wonder if all DVD players add a little overscan in???

PROBLEM SOLVED



The phillips dvd player was causing the problem. Bought a Samsung dvd player and it looks great. Now I just have to convince the people at best buy that the phillips is messed up. That should be good.
