Perhaps real blacks at last with the on/off/dimming technology that localized LEDs can offer. A decent technological direction to pursue. I've been impressed by Sony's latest LCD XRBs. These newer LCDs are not the gray washed-out compromises of yesterday. Kudos to Samsung. Let's wait and see if this technology works as well in real file.
