So far, organic light-emitting diode (OLED) technology has primarily been limited to curved displays manufactured by LG, like the Editors' Choice EG9600 series. Curved screens haven't exactly wowed us as a compelling feature for premium HDTVs, but until now we haven't been able to see if a flat panel OLED can produce the same results. That changes with the EF9500 series of ultra high-definition (UHD, or 4K) HDTVs. The 65-inch 65EF9500 ($4,999.99) stands as the first flat big-screen OLED we've tested. It looks, feels, and performs like a curve-free version of the 65EG9600. You won't save any money on the flat panel; the two models are priced the same, so it's more a matter of taste. We prefer flat, and for that reason, the LG 65EF9500 earns our Editors' Choice.

Design

Design-wise, the 65EF9500 looks almost identical to the 65EG9600. It shares the same half-inch black border flush against the screen, framed with a chrome band around the edge of the display. It sits on the same brushed silver-colored trapezoidal base with an acrylic stand that makes the display look as if it's floating. It has the same curved white plastic back panel covering two-thirds of the rear of the display. It even features the same tiny control stick/Power button hidden behind the LG logo on the bottom edge of the display. The big difference is that the screen itself is flat, not curved.

Three HDMI 2.0 ports, two USB 2.0 ports, a USB 3.0 port, and a 3.5mm audio output sit on the back of the HDTV facing left. A combination composite/component input that works with included 3.5mm adapters faces downward, along with a coaxial antenna/cable connector, an optical audio output, and an Ethernet port. Three HDMI ports seems paltry for a screen this size and price; four should be the minimum for this class of HDTV.
