Hi Guys,
I just bought acer monitor Ed242qr Abidpx earlier on July 2018 and notice to have white dead pixel on top center of the screen.
I already check the warranty (Expired on 7 March 2021)
I already try acer guide to use pixelhealer software but seem not working.
Is there any way to fix this because currently this is my main monitor and i don't have other monitor to use if i sent back to claim warranty or can i claim it and change 1 to 1?

    Hi, Every manufacturer follow Dead Pixel Policy for monitor. Acer also does...

    What is the Acer policy on defective or stuck pixel on my LCD display?

    LCD Display Pixel Introduction

    LCD displays are made up of a set number of pixels and each pixel is made from 3 sub-pixels - one Red, one Blue and one Green. Each sub-pixel has its own transistor, which makes manufacturing the glass substrate very complex.

    Due to the nature of the manufacturing process, occasional defects can occur. Pixel defects or failures cannot be fixed or repaired and can happen at any stage in the LCD's life. There are two types of pixel defects:

    • Bright Sub-Pixel: A sub-pixel is displayed as a small white dot on a black pattern.
    • Dark Sub-Pixel: A sub-pixel is displayed as a small black dot on a white pattern.

    Dead Pixel Warranty Policy

    The table below shows the allowable number of dead sub-pixels for the native resolution of the LCD panel. Your display can be replaced during the duration of the limited warranty period if the number of dead pixels is greater than the allowable number.

    General policy:

    Native ResolutionBright Sub-PixelDark Sub-PixelTotal Sub-Pixel
    SXGA1280*1024≤ 2≤ 5≤ 5
    HD1366*768≤ 2≤ 5≤ 5

    WQHD+3840*1600≤ 2≤ 5≤ 5

    Premium Model Policy:

    Note:
    1. A sub-pixel, less than or equal to 0.5 of a sub-pixel, is excluded from the warranty.
    2. Warranty duration and product specification may vary from different regions. Please contact local distributors/dealers for further information.
