Thinking of getting a 4k monitor down the line. But when it down scales to 1080p (for certain games or videos etc) how does it look? I'm kind of hoping that because it's 4x the resolution that it can just turn a square of 4 pixels into 1? Basically does it look as good as 1080p looks on a 1080p monitor? And side note. When will 4k monitors with a higher refresh rate arrive?
