[Galaxy Note 3 Q&A, Help & Troubleshooting] BarryH_GEG:
I think when you see the actual (vs. extended via PenTile) PPI count in the N3 you'll find that it has a higher native PPI than the N2's; probably in the 290's.

Here's how it worked out on the SGS4. Keep in mind your N2 has a PPI of 267...

PenTile Displays

The pixels on most current OLED displays have only 2 sub-pixels in each pixel instead of the standard 3 Red, Green, and Blue sub-pixels found in most other displays and display technologies. Half of the PenTile pixels have Green and Red sub-pixels and the other half have Green and Blue sub-pixels, so Red and Blue are always shared by two adjacent pixels. This makes PenTile displays easier to manufacture and at a lower cost. It also improves brightness and reduces aging effects. Because the eye has lower visual acuity for color this works very well for photographic and video images. But for digitally generated fine text and graphics with precise pixel layouts the eye can visually detect the reduced number of Red and Blue sub-pixels unless the number of Red and Blue Sub-Pixels Per Inch is very high. And it is

for the Galaxy S4 – there are 312 Red and Blue Sub-Pixels Per Inch

, which is only a few percent lower than Apple’s Benchmark 326 PPI iPhone Retina Display. Visually the Galaxy S4 PenTile display delivers excellent visual sharpness across the board.​

And how the Diamond Pixels arrangement works...

Diamond Pixels

A high resolution screen shot of the Galaxy S4 (provided by Samsung) shows an interesting design and sub-pixel arrangement, which Samsung calls Diamond Pixels. First of all, the Red, Green, and Blue sub-pixels have very different sizes – Blue is by far the largest because it has the lowest efficiency, and Green is by far the smallest because it has the highest efficiency. The alternating Red and Blue sub-pixel PenTile arrangement discussed above leads to a 45 degree diagonal symmetry in the sub-pixel layout. Then, in order to maximize the sub-pixel packing and achieve the highest possible PPI, that leads to diamond rather than square or stripe shaped Red and Blue sub-pixels. But not for the Green sub-pixels, which are oval shaped because they are squeezed between two much larger and different sized Red and Blue sub-pixels. It’s display art…​

And the need for all those pixels, raw or extended via PenTile, are still questionable...

400+ Pixels Per Inch Displays

Apple started a major revolution in display marketing by introducing their “Retina Display” with 326 Pixels Per Inch (PPI) on the iPhone 4 in 2010. While not equivalent to the resolution of the human retina, people with 20/20 Vision cannot resolve the individual pixels when the display is held at normal viewing distances of 10.5 inches or more. It started a display PPI and Mega Pixel war similar to what happened with Smartphone digital cameras, which is still an ongoing wild goose chase now into the stratosphere… Hopefully the same thing won’t happen with mobile displays because there are tradeoffs involved that affect other important display performance issues. The real question is how high do we need to go before reaching a practical visual PPI limit? I’ll cover this in an upcoming article. However, a new generation of 400+ PPI displays is already here, driven by the desire to produce a Full HD 1920x1080 display on a Smartphone screen. The Galaxy S4 has an incredible 441 Pixels Per Inch. People with 20/20 Vision cannot resolve the individual pixels on a 441 PPI display for viewing distances of 7.8 inches or more, which is exceedingly close for viewing a 5.0 inch display. http://www.displaymate.com/Galaxy_S4_ShootOut_1.htm​

Anyone who thinks the N2 display will be in any way better than the N3's isn't looking at the facts. The N3's display will be bigger, brighter, more power efficient, have a higher PPI (base and extended) and produce improved and more accurate colors. Unless of course you think Samsung would equip the N3 with a display inferior to the N2 and SGS4's. I think people that glom on to PenTile as something bad do so without really understanding how it's being applied starting with the SGS4. In terms of raw pixels the N3 will still have more than the N2 so one could say anything above that, along with the other features of the more modern display, is just a bonus. Unless anyone here wears jeweler’s eyes for glasses or holds their phone less than 7" from their face the pixel geometry of the N3's PenTile display will be invisible.

Here's what GSMArena said about the N3's display from their un-boxing...

Moving on to hardware. Samsung has made it a custom to improve its smartphones while managing to keep the proportions the same or even tighter than before. Despite weighing less (168 g vs 183 g), being thinner and narrower than the Galaxy Note II, the Note 3 makes it look as obsolete as 2011. The screen is now 5.7″ in place of 5.5″ and the resolution has more than doubled from 720p to 1080p resulting in a ppi of around 386. The phone has sharper edges, the all plastic built has been retained but the back panel is now made from soft-touch plastic, that quite successfully emulates leather in both looks and feel. There are even stitching in place, which are also part of the plastic. The new soft-touch back panel feels more refined, better on the touch and appears tougher.

The loss of weight will be immediately felt by Note II users and so will the increase of the screen resolution. The display on the Note 3 is among the best we’ve used, if not the best.
