4K monitors do not need to be bigger than 32 inches in size
My son has a 26 inch 4K monitor which he used with his PC for software development, playing games and watching Youtube clips. He gets the full 4K effect because he sits two foot away from it None of my family really ever watch our 720p 22 inch TV and so we will never buy a 47 inch 4K monster.
