FHD? 1080P? 2K? 4K?

1920X1080 = FHD = 1080P = 1K

1920X1200 = WUXGA = 1200P ≒ 1K

2560X1080 = WFHD = 1080P ≒ 1.5K

2560X1440 = QHD = 1440P = 2K

3440x1440 = WQHD = 1440P ≒ 2K

5120x1440 = DQHD = 1440P ≒ 2K

3840X1600 = Movie 4K = 1600P = 2K

3840X2160 = UHD = 2160p = 4K

4096x2160 = DCI 4K = 2160P = 4K
