I got an Acer W4 windows 8.1 tablet, normally there is nothing wrong with the display (for example right now that Im typing) or when Im playing with it BUT sometimes I see a colorful dot on my screen, I thought its a dead pixel, I checked my tablet with Udpixel and I didnt find any dead pixel
it is usually ok but sometimes bothers me
help!!!
