LG pixelhiba politika
3 napon belül az LG minden pixelhibára (akár egyetlen alpixelre is cseréli az LCD monitorjait!

3 nap után az alábbi garancia érvényes:
Az LG nem enged meg főpixel-hibát, teljes pixelhibánál (ami három alpixelből áll) a monitor cserére jogosult. 1 teljes pixel, (főpixel) hibája egy nagy, 0,2mm nagyságú hibás képpontot hoz létre a képernyőn. Nagyító alatt ilyenkor látszik, hogy mindhárom alképpont működésképtelen.
 

Mivel a főpixel-hibás monitorok rendkívül ritkák és cserére jogosultak, az LG hibás pixelre vonatkozó leírásai alpixelekben megfogalmazottak.

1 pixel 3 alpixelbĹ‘l áll – vörösbĹ‘l, zöldbĹ‘l, kĂ©kbĹ‘l. Az alpixelek ezen kombináciĂłja biztosĂ­ja azt a teljes szĂ­ntartományt, ami a kĂ©pernyĹ‘n mint 1 fĹ‘kĂ©ppont (fĹ‘pixel) kerĂĽl kijelzĂ©sre.
A következőkben megfogalmazott pixel-hiba kritérium szigorúbb, mint a vonatkozó ISO előírások (ISO 13406-2, class 2).

Acer TFT pixelhiba-mentesség biztosítás

Acer Platinum garanciakiterjesztés csomag

Az LCD-monitorok TFT-kijelzőjén esetlegesen előforduló pixelhibák nem minősülnek garanciális hibának, csak egyes, kirívó esetekben.

A korlátozott jĂłtállás nem terjed ki az LCD technolĂłgiával kĂ©szĂĽlt monitorok kisebb hibáira. Az adott LCD kijelzĹ‘n egymilliĂł kĂ©ppontonkĂ©nt nĂ©gy (4) hibás kĂ©ppont, illetve – a kijelzĹ‘panelt kilenc (9) egyenlĹ‘ nĂ©gyszögletes terĂĽletre osztva – a kijelzĹ‘ közĂ©psĹ‘ rĂ©szĂ©n legfeljebb egyetlen hibás kĂ©ppont mĂ©g elfogadhatĂł hibának minĹ‘sĂĽl.

A középen található zöld terület a kijelző középső része, ahol legfeljebb egy hibás képpont lehet.

The Limited Warranty does not extend to minor defects of LCD displays occurring in Products equipped with LCD display technology provided that there shall not be more than four (4) defective pixels per million pixels on a given LCD Display, and provided further that, if the display panel is divided into nine (9) equal rectangular areas, there shall be one defective pixel in the central area of the display.

The green Area in the middle is the central area of the display with no more then one defective pixel.

800 X 600 X 3 = 1,440,000

1,024 X 768 X 3 = 2,359,296

1,280 X 1,024 X 3 = 3,932,160

1,400 X 1,050 X 3 = 4,410,000

Hibás képpontokra vonatkozó irányelvek

A PDÁ-k LCD-kijelzőjének fényes és sötét hibás képpontjaira vonatkozó irányelv szerint az alábbiak még elfogadható hibának minősülnek. Amennyiben az LCD-kijelzőn a lent meghatározottnál kevesebb hibás képpont található, az LCD-kijelzőt nem cseréljük:

– fĂ©nyes kĂ©ppont: 3 vagy annál kevesebb,

– sötĂ©t kĂ©ppont: 3 vagy annál kevesebb,

– teljes kĂ©ppont: 3 vagy annál kevesebb.

Feltéve, hogy az LCD-kijelző középső szektorában nincs hibás képpont.

Az Ăşgynevezett „Newton ring” effektus (szivárványhatás, amit a kĂ©ppontok egyenletlen nagysága okoz) esetenkĂ©nt megengedett – a helyzetĂ©tĹ‘l, a Newton ring mĂ©retĂ©tĹ‘l, illetve attĂłl fĂĽggĹ‘en, hogy mennyire látszik.

(a) A képponthiba:

(i) A képponthiba a képpont területének a hibája, amelynek nagysága a képpont területének több, mint 50%-a.

(ii) A képpont kis, fényes hibája az RGB színek valamelyikének a hibája, melynek nagysága a képpont területének kisebb, mint a fele.

(b) Két sötét képponthiba vagy két fényes képponthiba közötti távolságnak 3 mm-nél nagyobbnak kell lennie.

(c) A fényes és sötét kapcsolt képponthibák a következők:

(i) két pár két képpontból álló kapcsolt, fényes képponthiba még elfogadható,

(ii) két pár két képpontból álló kapcsolt, sötét képponthiba még elfogadható,

(iii) két kapcsolt, fényes, hibás képpont két fényes, hibás képpontnak tekintendő,

(iv) két kapcsolt, sötét, hibás képpont két sötét, hibás képpontnak tekintendő,

(v) három kapcsolt, fényes, hibás képpont nem elfogadható,

(vi) három kapcsolt, sötét, hibás képpont nem elfogadható,

(vii) egy fényes és egy sötét képpont kapcsolata egy fényes és egy sötét, hibás képpontnak tekintendő.

LCD Display Pixel Policy

During the LCD Monitor manufacturing process, it is not uncommon for one or more pixels to become fixed in an unchanging state. The visible result is a fixed pixel that appears as an extremely tiny dark or bright discolored dot. When the pixel remains permanently lit, it is known as a “bright dot.” When the pixel remains black, it is known as a “dark dot.”

In almost every case, these fixed pixels are hard to see and do not detract from display quality or usability. A display with 1 to 5 bright or dark dots is considered normal and within competitive standards.

Dell LCD Replacement Policy

Your LCD display is subject to replacement if it meets the criteria outlined in the following table:

  Bright Dots Dark Dots Total Dots
