    16:9 @ 1080 on a 1080 screen vs 16:9 @ 1080 on a 720 screen should scale similarly.
    "A 1080p display might also be useful for simply viewing 19201080 content and not worrying about scaling. "Every time you rescale content that’s scaled for some other resolution, it’s not going to look as good. So there’s an advantage to living with 19201080 even if your eye can’t appreciate the fine details, because you don’t have the rescaling artifacts," he says."

    1080p on a smartphone screen—can it possibly matter? | Ars Technica

    So if you're trying to view 1080p content on a 720p screen there's scaling. The 1080p content gets scaled to 720p and that can create black bars, pixelated artifacts, etc. So 16:9 1080 scales correctly on a 1080 screen. 16:9 720 scales correctly on a 720 screen. But 16:9 1080 does not scale correctly on a 720 screen.

    I'd like to think that since we saw some branches pop up last week in AOSP that Google will be releasing 4.3.1 "soon" so Motorola decided to wait for that while tweaking their customizations and making other improvements. This would allow them to just sync their source with AOSP, get all of the bug fixes/improvements of 4.3.1 and then quickly release it as an OTA.

    Now this could just be wishful thinking and we might see a 4.3 release in November or December for all I know.....

    If black bars appear when viewing 1080 content on a 16:9 1080 screen, the ratio of black bars should be the same when viewing that same 1080 content on a 16:9 720 screen. The aspect ratios are the same.

    I'm explicitly referring to the black bars you mention. Yes, you may be artifacts or pixelation but I don't see how black bars will be introduced if the aspect ratios are the same. Please show me how that math works.

    Also in regards to the whole 720p vs 1080p debate something I think people are forgetting is how many people actually watch a "true" 1080p video on their phone? A straight bluray movie rip would be about 30-40GB so much larger than the available internal storage allows. So if you are watching a 1080p video it's going to be compressed somewhat already which in of itself will lead to artifacts or pixelation. In short? It doesn't matter that this phone has a 720p display.

    There are always black bars present when viewing 1080p content in 16:9 ratio. But taking 1080p content and putting it on a 720p screen makes them black bars significantly worse because of scaling. Go put a blue ray movie on a 720p screen and set the TV aspect ratio to 16:9 and see what happens. Change the ratio to "wide" on the TV and it scales to fill the screen.

    I'm not talking about ripped blue ray content. In and of itself I totally agree with you. I'm talking anything....such as the new HD stream from Netflix, Hulu, or anything that sends HDX or 1080p content....you have to watch it in a lower resolution and/or a different aspect ratio to view it correctly. You can still view it natively but it won't be right.

    Black bars are not always present when viewing 1080 content in a 16:9 ratio. If the video was shot 1920x1080 it will display without black bars on a 16:9 display.

    Do the math.

    If 1080 content has black bars on a 16:9 1080 display, that same 1080 content will have black bars on a 16:9 720 display. However, the ratio of "black bars to actual content" will be the same on either display. They both have the same 16:9 aspect ratio. 1920x1080 scales with 1280x720.

    If 1080 content fills the entire 16:9 1080 display, that same 1080 content will also fill a 16:9 720 display. You will not get black bars on the 720 display. And if you are, a setting is probably incorrect.

    And to end it - what are the video camera settings on the Moto X?

    The Moto X shoots at 1080, 16:9 (1920x1080). The Moto X display is 1280x720. Play back a video you recorded. Show me the black bars.
