Samsung makes some really high quality displays. Their quantum dot displays achieve 95% of the image quality of OLED. LED LCDs get the job done. I just held out until the 4K displays matured.
The other day I bought a Sony 4k Player and it is sweet. Much nicer than the one it replaces, which is now in the bedroom. Did I REALLY need it? No! But I love it, just the same.
