|Display - Pros & Cons|
1. Have you ever heard about a five inches screen that made headlines? With S4, you get one.
2. Its a 1920x1080 pixel, full HD, PenTile RGBG and 441.46 pixels per inch (441ppi) image density, 5-inch Super AMOLED backlit screen.
3. It's the same Super AMOLED technology used in other Galaxy smartphones, but this time it's been extended upto Full HD resolution, which is 1920 x 1080pixels.
4. The S4 features a high-definition Super AMOLED screen with a resolution of 441 pixels per inch (ppi). Apple's iPhone 5 Retina display has a resolution of 326 ppi, thus sharper than the iPhone's 326ppi and only very slightly below the HTC One's 468ppi (though at 4.7-inch that's a smaller screen on the One).
5. The most distinguishable difference between it and the S3 is, it promptly makes the Samsung Galaxy S3 look dated and dull.
6. Although not the first phone to have a 1080p display, it is Samsung's first Full HD phone.
7. High contrast ratios on offer.
8. A new type of screen. Samsung has hooked in a mode to make the colours look more natural. This method does lower the brightness a bit. The hitch is that's already lower than the HTC One, but that extra brightness isn't required due to the contrast ratio it offers. 
9. It's bright, but wont burn your eyes. With most modern smart phone displays, you have to take care of your eye sight. S4 is not an eye burner or an oven but a smart phone that is selling like Hot Cakes.
10. Poor performance under direct sunlight, but not so timid under indoor light sources.
11. The screen is capable of sensing touches with gloves on. Not available on majority of phones.
12. The Blues look brighter.
13. Jet Blacks!
14. More pixels mean sharper images.
15. Different colour profiles in the settings menu.
16. Color accuracy is improved compared to early Super AMOLEDs.
17. No yellow or greenish discoloration in white areas.
18. A wider screen which means a wider keyboard and more space to type on.
19. A 1080p display and a pixel density of 441 per inch, more than required to get rid of any traits of pixelation.
20. A bigger and grand gaming experience on a smart phone.
21. A mini theater for movies.
22. HD TVs have the same resolution (whopping 5-inch display with Full HD resolution, the same amount of pixels you'd have seen on a TV).
23. The screen is super-sensitive which allows it to track your finger, even when it's hovering above, but not touching it.
24. The thin screen bezel makes it look as if the screen is coming out of the edge of the phone.
25. The air gap that fils the gap between the screen and the touch digitiser is drastically tiny. It makes it feel almost as if you're touching the colourful interface rather than the glass on top of it.
26. It's crisp and sharp. Text is crisp, colors are vibrant and blacks are deep.
27. Not even a single trace of pixelisation when having a closure look on application icons or text (no pixelated edges in the margins of the icons and text). From web pages to video, looks great. Large passages in Web pages are pleasurable to read.
28. 441 pixels per inch, text she sent is crystal clear but not the hell she means.
29. The Gorilla Glass 3 resides millimeters below the edge of the screen. This makes the screen less vulnerable than the GS3 (glass sits slightly above the edge in it). This will make your screen safer when dropped.
30. The Gorilla Glass 3 is based on a new glass composition. The third gen screen coating delivers increased impact and scratch resistance. The Galaxy S4 is actually harder to scratch than its predecessor.
31. Sony Z has same size screen. However, Sony Z's home, menu, and back buttons are part of the screen. It means the screen size is less than 5" while the S4 is realistically a jumbo 5".
32. An impressive contrast and perfect viewing angles make everything on the screen eye candy, regardless of your viewing angle.
33. An advanced capacitive touchscreen powered by Synaptics, also known as ClearPad. The all brand new "Synaptics ClearPad" detects finger from just 2cm away.
34. The ultra sensitivity makes it possible to use AirView without an S Pen, touch the screen while wearing gloves. And the good news is you can manage that extra sensitivity if you've activated the "extra sensitivity mode" in the settings.
35. S Pen doesnt work on S4s. It lacks a Wacom digitizer. But C-Pens and other capacitive styluses would do the trick.
36. The 441-pixels-per-inch resolution compensates for the weaknesses of the PenTile Matrix to a certain extent.
37. Can change the brightness from the very notification bar.
38. You can let the Auto Brightness mode to optimize the brightness for you.
39. The Auto Brightness mode even lets the user to customise the auto level. Salubrious for the battery life.
40. You are well guided through your two centimeters away finger hoverings, a light flickers under your finger.
41. High-definition images are a please to see.
42. Colours are rich and bold.
43. The resolution of the S4 display is comparable to that of the iPhone 5's Retina display.
44. A bigger screen is also better for viewing charts, portfolio list, and company snapshots.
45. Dont have to worry about the tints of the previous version.
46. Samsung making over-saturated screens is a thing of the past.
47. The color saturation is way beyond the reach of any LCD on the market. It makes even the gloomiest image appear majestically vibrant. Besides, if you are not a guy of the oversaturated look of AMOLEDs, Samsung provides you an option to slow down the saturation to more down to earth levels. There's a dedicated Adobe RGB setting that gets this done. So you can relish both of the worlds.
48. The structure of the PenTile matrix has been changed too. Now green sub-pixels are twice as many as blue and red sub-pixels, and the arrangement is changed as well. Thankfully, the 441 ppi pixel density makes sure you won't be able to spot much the hated cross-hatch pattern.
49. Its whopping 1,920x1,080-pixel resolution. That's Full HD and an impressive boost from the 720p display of the Galaxy S3.
50. The touchscreen controller, a Synaptics S5000B is the chip which is responsible for the S4's super-sensitive touchscreen, which even works with gloves, is hiding behind the screen.
51. The level of color toned down from the GS3. Images match the natural color reproduction of the HTC One.
52. Screen's overall brightness and color quality is as good as on any AMOLED display, including the Galaxy Note 2.
53. It's not as high resolution as the HTC One, because it's larger with the same amount of pixels, but when viewed closely, viewer struggles to find any flaw with it.
54. Where lies the strengths of OLED? When a pixel is displaying a black image, it's completely off, thus consumes less power and looks darker. On contrary, LCD screens have a backlight to light the colours in front which means that the blacks will never be as black as found on an OLED.
55. Truly, the colours look too strong on the device thanks to the OLED technology used.
