The Samsung LE40A558 40in LCD TV is perhaps the basic LCD TV you can get in the market today. It is suitable for people who want to experience the magic of LCD viewing in the basic way. It has simple connections like three HDMIs, a side-mounted USB port for playing MP3 music and JPEG stills into the TV from USB storage devices, and a dedicated D-Sub PC port.
As far as user flexibility is concerned, this model has its share of fairly reasonable features. The LE40A558 LCD TV model has a black adjustment, an optional, multi-level Dynamic Contrast system, gamma adjustment, white balance fine-tuning, fleshtone adjustments, Edge Enhancement, noise reduction, and Samsung’s Movie Plus system, which interpolates extra frames of image data in a bid to reproduce motion more naturally.
