[Galaxy Note 10.1 (2014 Edition) General] BarryH_GEG:
Turn your N10.1-14 off and hold it an angle under a very bright light. You'll see an elaborate matrix/grid that is what allows the active digitizer to recognize the presence of the pen. Any photo you take is going to pick up the reflection of the grid and will have a moiré affect that isn't representative of what's actually being displayed.

In this example, the pic looks like crap but viewed in person the detail of the install button is no different between my N10.1-14 and N3 (2nd pic).

I'll say this, the addition of a white sub-pixel is very unusual. It's possible that when certain colors are displayed together at certain saturation and/or brightness levels they are affecting each other and could create what you are seeing.

Here's how RGBW works from Wiki...

PenTile RGBW technology, used in LCD, adds an extra subpixel to the traditional red, green and blue subpixels that is a clear area without color filtering material and with the only purpose of letting backlight come through, hence W for white. This makes it possible to produce a brighter image compared to an RGB-matrix while using the same amount of power, or produce an equally bright image while using less power.

The PenTile RGBW layout uses each red, green, blue and white subpixel to present high-resolution luminance information to the human eyes' red-sensing and green-sensing cone cells, while using the combined effect of all the color subpixels to present lower-resolution chroma (color) information to all three cone cell types. Combined, this optimizes the match of display technology to the biological mechanisms of human vision.[13] The layout uses one third fewer subpixels for the same resolution as the RGB stripe (RGB-RGB) layout, in spite of having four color primaries instead of the conventional three, using subpixel rendering combined with metamer rendering. Metamer rendering optimizes the energy distribution between the white subpixel and the combined red, green, and blue subpixels: W <> RGB, to improve image sharpness.

The display driver chip has an RGB to RGBW color vector space converter and gamut mapping algorithm, followed by metamer and subpixel rendering algorithms. In order to maintain saturated color quality, to avoid simultaneous contrast error between saturated colors and peak white brightness, while simultaneously reducing backlight power requirements, the display backlight brightness is under control of the PenTile driver engine. When the image is mostly desaturated colors, those near white or grey, the backlight brightness is significantly reduced, often to less than 50% peak, while the LCD levels are increased to compensate. When the image has very bright saturated colors, the backlight brightness is maintained at higher levels. The PenTile RGBW also has an optional high brightness mode that doubles the brightness of the desaturated color image areas, such as black&white text, for improved outdoor view-ability.​

The active matrix grid is also much more pronounced on the N10.1-14 than it was on the N10.1-12; probably to support the much higher display resolution. For those with better than 20/20 vision maybe that's affecting what you're seeing. It's all controlled by Samsung's video and PenTile drivers so perhaps with tuning and updates whatever's bothering you will improve. Incidentally, Samsung bought Clairvoyante, the developer of PenTile, so in essence Samsung owns PenTile.

But it's still odd that so few people see what you're describing and that it wasn't caught by AnandTech, GSMArena, and NoteBookCheck DE which all do exhaustive objective testing. Brian Klug from AnandTech, with an under grad in optical engineering, mentioned he noticed something different about the display but if there was display distortion like you're describing I'm sure he would have elaborated. I sure can't see what you're describing using my N3 with a higher PPI count as a baseline. The panels used in the N10.1-14 aren't necessarily all made in the same factory. There could also be allowable differences in tolerances in manufacturing between them. So maybe some do perform differently which is why some of you are seeing things others don't.

[MENTION=426561]scrosler[/MENTION] is brilliant but based on the detail from Wiki of how RGBW is tuned unless he decompiles Samsung's PenTile drivers and re-tunes them down to the sub-pixel level it's likely what you have in front of you is what you're going to have to live with. If you're still in your return period and the display is your number one priority you should probably look at the iPad Air or if you want to stay with Android the Nexus 10 and Asus TF701 which have displays with same resolution as the N10.1-14.

If you read the way RGBW works above it makes sense that yellow and white used in combination because of the lack of contrast would be difficult to render. I did what you said but truthfully my take away was not to use yellow on a white background in my note taking. The yellow literally appeared to throb against the white background especially in S Note which ups the display to 100% brightness. Interestingly, I've frequently used yellow to highlight things and when another color's involved it renders normally.

I think some of you folks are being perfectionists which is certainly your right for the money you've spent. Based on what you're reporting I'd say the likelihood of anything changing is pretty slim. So your choices are either live with it or get your money back and buy something you find more suitable to your needs.

Either my eyes are different than yours or my expectations are lower but none of this discussion has changed the way I feel about the N10.1-14's display. I think it's gorgeous and the primary reason someone should consider a N10.1-14.

P.S. - The Tab|Pro 10.1 will have a different display than the N10.1-14 because without S Pen it won't be inductive nor need an active digitizer. Maybe those unhappy with the N10.1-14's display should look at that. You're going to give up S Pen anyway if you decide to return the N10.1-14 and get something else.
