μηπως επειδη η non official οθονη σου ειναι "λαθος" ρυθμισμενη ?
Απο το link που εβαλα παραπανω και ολα τα review που εχουμε δει, η νεα οθονη ειναι πολυ πιο "σωστη" και ζωντανη.
εχει πολυ μεγαλυτερη φωτεινοτητα , πολυ ακριβης χρωματικη αποδοση .
για οποιον βαριεται να διαβαζει ολα τα τεστ...
Conclusions: An Impressive iPhone 5 Display
Smartphone displays are continuing their rapid evolution in performance. Apple has again taken the lead in methodical refinements and factory calibration that are necessary to produce accurate very high picture quality. Based on our extensive lab measurements the iPhone 5 has a true state-of-the-art accurate display—it's not perfect and there is plenty of room for improvements (and competitors) but it is the best smartphone display we have seen to date based on extensive lab measurements and viewing tests. In particular it is a significant improvement over the display in the iPhone 4 with much lower screen reflections, much higher image contrast and screen readability in high ambient lighting (the highest we have ever measured), and a significantly improved and accurate color gamut and factory calibration that delivers very accurate colors and very good picture quality. While it's not quite as accurate as the new iPad, it is still probably more accurate than any consumer display you own (including your HDTV), unless you have a new iPad.
The display on the Samsung Galaxy S III uses OLED technology. It's a new technology that has not yet been refined to the same degree as LCDs, particularly the IPS LCDs on the iPhones, so it doesn't objectively test or perform as well as the iPhone 5. But OLEDs have been evolving and improving very rapidly as shown in our OLED Display Technology Shoot-Out so it has a very promising future. Here are the biggest issues we found in our extensive lab measurements and viewing tests of the Galaxy S III: the brightness is about half of the iPhone 5 due to power constraints resulting from the lower OLED power efficiency and concerns regarding premature OLED aging. As a result the image contrast and screen readability in high ambient lighting is much poorer than the iPhone 5. The color gamut is not only much larger than the standard color gamut, which leads to distorted and exaggerated colors, but the gamut is quite lopsided, with green being a lot more saturated than either red or blue, which adds a green color caste to many images. And for some reason Samsung has not bothered to calibrate the color gamut on any of its OLED displays, so they are wildly inaccurate and produce inaccurate and over saturated colors.
Suggestions for Apple: Keep up the good work in improving picture quality through accurate display calibration! To produce a better display please don't make the White Point Color Temperature so blue—it's the only significant calibration flaw and it gives some images a bit of a cold bluish caste. The Intensity Scale on the iPhone 5 should be changed to match the excellent calibration of the new iPad. Finally, consumers have varying tastes in color saturation and image contrast—why not give displays the equivalent of an audio equalizer to let everyone adjust the display to their own personal visual preferences?
Suggestions for Samsung: Keep up the good work in improving OLED displays! To produce a better OLED Smartphone, use a smaller size display (that uses less power), add a bigger battery to increase the screen brightness and running time on battery, and most all—please calibrate the display so that its color gamut matches the standard color gamut and the display delivers accurate rather than distorted, exaggerated, and gaudy colors!
Suggestions for all manufacturers: There is still plenty of room for improvement. See the new iPad shoot-out conclusion for a discussion of the many improvements that are needed for the next generation of Smartphone and Tablet displays.
