tie kontrasty v PSREF su uplne mimo reality hlavne pre HDcka a 14tky.
L412 ma uplne to iste uvedene co L420
14.0" (355mm) HD (1366x768) color, anti-glare, LED backlight,
220 nits, 16:9 aspect ratio, 500:1 contrast ratio
a realita vyzera takto

L420 sa s HD+ nerobi aj keby sa robil tak ta to nevytrhne lebo tie 14,0" HD+ displeje su +/- to iste bez ohladu na to ci su v Lenove T420, HPckach 6460b/8460p/8460w alebo v Delloch E5420/E6420.

afaik jediny 14" displej porovnatelny s hires 15tkami bol 14,5" Radiance Infinity Display v HP Envy 14. bohuzial pre teba ma 2 chyby: je leskly rovnako ako displeje na Macbookoch a uz sa nepredava :)

ten FullHD displej na T520 a W520 je po ukonceni W70x serie asi to najlepsie TN-ko co sa dava do Thinkpadov pokial sa ti ho podari dobre skalibrovat (6bit vs widegamut). podla for je to tento konkretny displej, ktory sa daval uz do W510tky http://www.notebook-lcd.ru/pdf/B156HW01_V_4.pdf

inak k tomu 95% gamutu je este vhodne doplnit toto:
I was investigating about that gamut and quality thing and finally I can tell you where is the "but".

It is all about that "gamut" word. Professional grade monitors mean by gamut "gamut coverage", but mainstream and low-end manufacturers mean by gamut "gamut volume". If you seriously work with photography, or pre-press, you probably working in sRGB, A-RGB or NTSC. If lenovo tell you that they have 95 % NTSC, it is not mean they cover 95 % of NTSC 3D gamut model, but that the volume of 3D model on their screen is 95% of volume of gamut NTSC 3D model. Yes, that mean, that this has no relation what so ever with the gamut coverage, so theoretically you can have 100% volume gamut, and the screen cannot reproduce a single one color of that gamut. The reason why manufacturers are doing this is simple - marketing - the numbers are bigger. This also solve the miracle when on anandtech you can see 120% gamut monitors etc. Then people here are disappointed that the colors are oversaturated, ugly, non-real etc. They are there, but they are wrong.
