TVs at CES 2015 go beyond 4K

4K is already old hat. The rapidly falling prices of 4K TVs are causing manufacturers push even more elaborate features to make a buck. That's why quantum dots, HDR and curved, bendable and ultra-slim TVs were so prominent this year.

LAS VEGAS -- The marketing departments at major TV makers love their buzzwords, and none more than Samsung.

The world's biggest TV maker and dominant force in 4K UHD sales bet big on a confusing array of new terms at CES 2015, beginning with S(don't-call-me-Super)UHD. Other TV makers joined in too, addingHDR, pixel splitting and numerous other enhancements to their best TVs.

The reason is simple: 4K TVs are dropping to mainstream prices fast, so something else is needed to sell profitable, high-end TVs. Both Samsung and LG, the #2 TV maker, introduced more lines of 4K TVs than 1080p TVs at the show, and Sony's ratio of 4K to 1080p series was 4:1. The show's big booths were packed with 4K sets with very few 1080p models on hand.
