I often remain sceptical about such claims, and wait until I go eyes-on to make my own judgement.

I was gobsmacked by the differences.

But as soon as I fired up the G4, I noticed a subtle but significant visual difference.

This results in a picture with, to my eyes, more obvious depth.

Indeed, the image produced by the G4 OLED is going to be closer to what the director intended.

The LG G4 OLED is a sensational TV, and it makes multiple improvements over its predecessor.

That’s ultimately hard to answer, because budget constraints may not allow for starters.
