How It Compares

Within NEC's M Series family, the M551 shares the IPS/Edge‑LED technology and 16:9 aspect ratio of models like the M431, M491, and M651, differing mainly in screen size and bezel dimensions. Variants such as the M551‑MPi4 add a built‑in MediaPlayer, while the PG‑2 version increases weight and bezel size for added durability and protective glass, but all retain EnergyStar 8.0 and Class G efficiency.
