Samsung Galaxy Note BLACK CRUSH Demo [Compared With Samsung Captivate]
Jul 12th 2012, 21:47


The Samsung Captivate is on the left.
The Samsung Galaxy Note is on the right.

Both are from AT&T and are USA models.

The first part shows a test pattern which shows a gray scale with numbers from 0 - 21. This clearly shows extreme black clipping on the Note as it has little to no gray scale gradations from 21 to 1, and then 0 just suddenly turns black.

The Captivate clearly shows a more accurate rendering of proper gray scale with white gradually changing to black.

The second part shows a You Tube clip which looks as it should on the Captivate, but breaks up into an almost unwatchable mess during dark scenes.

I'm not sure If I had the Captivate set to HQ on the You Tube stream, so if you notice banding, that's probably why. But this is not a video compression demo. It is only meant to show the black crush problem of the Galaxy Note.

I am hopeful that a solution to this problem will be forthcoming from Samsung.

You may download the test pattern shown in the video here:

If your Note can display the test pattern correctly, I would love to see the pictures.

here is the link for the Glee clip::

If anyone out there has a Samsung Galaxy Note that can display the test pattern correctly, would you please take a picture of it (NOT a screen shot, an actual picture) and share it.

Again, I repeat, this is NOT about compression artifacts. It is ONLY about the proper rendering of the gamma / gray scale. Even if you play a video of the highest possible quality (compression wise) on the Note, you will still see black clipping / crush when there is a fade in/out, or a very dark scene.
