The Latest: Deciphering the alphabet soup of new TV features

TV manufacturers are showcasing new models at the CES gadget show in Las Vegas this week -- all with acronyms to set their sets apart. One feature called HDR10 takes what's known as high-dynamic range and adjusts settings for each frame, instead of having levels set for the entire video at once. HDR10 is also a way to get around royalty payments for a competing technology called Dolby Vision. Meanwhile, quantum-dot technology promises more accurate colors. Samsung calls its version QLED (pronounced q-led), which shouldn't be confused with OLED (o-led), a display that offers darker blacks and better contrast.
