The ($560 unlocked; price as of 7/5/12) is LG's first foray into the quad-core world. Announced some four months ago at the , the 4X HD is powered by an Nvidia Tegra 3 processor, but that's not its only highlight. It also has a 4.7-inch display with a 1280-pixel-by-720-pixel resolution. The Optimus 4X HD is currently available in Europe and will arrive in Asia, South and Central America, and Russia in coming months. So far, LG hasn't announced any North American availability for the 4X HD. LG's Android phones haven't been wildly successful here in the United States, but this model has what it takes to make a splash in this country.
Design and Display
The Optimus 4X HD is superthin at 0.35 inch; however, it isn't going to win any awards in the beauty department with its sterile look, rigid rectangular shape, and textured plastic battery cover. We received a white version for review; it's much more attractive than the black version I saw at the Mobile World Congress.
The 4X HD has what LG is calling a "True HD IPS" display. Blacks look very deep, colors vivid, and whites bright. The screen does suffer from oversaturation, though, as our color-bar and grayscale tests showed. In our color-bar test, colors bled into each other; in the grayscale test, we had trouble differentiating the light-to-dark shades from one another. We've found oversaturation to be a fairly common problem across multiple phones. But saturation isn't always a bad thing. We've already mentioned the good colors. Details usually were also quite sharp in photos, but text rendering wasn't perfect. Sometimes text looked a bit pixelated and fuzzy when viewing certain websites. But for gaming, video-watching, and casual Web browsing, the Optimus's display is excellent.
