No, your screen doesn't need adjusting. This photo you see here depicts LG's new 38-inch "stretched" LCD monitor.
It's one of two elongated models, the other being 29 inches, for situations where extra-wide displays are needed, such as commercial signage. That must be why its resolution--1,366 x 480--is relatively low, as it's probably not ideal for close-up reading.
The company says these monitors, which are destined for the U.K. market, work equally well either vertically or horizontally. Just keep your distance.
