Generally, the preferred viewing distance is between 20 and 40 inches (50 and 100 cm) from the eye to the front surface of the computer screen. The LG 27'' UltraGear™ QHD Nano IPS 1ms 144Hz G-SYNC Compatible Gaming Monitor, Model # 27GN850-B has a native resolution of 2560 x 1440 and the recommended minimum viewing distance based on the peripheral field of vision of the human eye is 0.43 m / 1.4 ft. The correct distance is at least at the point where you can’t make out individual pixels, so it is heavily influenced also by the resolution of the display (among other factors). If you sit closer than this distance, and you look at the middle of the screen, you won’t be able to see its sides comfortably with your peripheral vision. The minimum distance mentioned above is based on visual acuity of 0.79 m / 2.6 ft. The human eye has its own limits. The visual acuity distance represents the point beyond which the human eye with 20/20 vision isn’t able to resolve some details in the picture, so they blend with the adjacent ones. 20/20 vision is a term used to express normal visual acuity measured at a distance of 20 feet. It indicates the sharpness or clarity of vision at a distance. Note that having 20/20 vision doesn’t necessarily mean you have a perfect sight. There is no the best distance that works well for everyone because it doesn’t depend only on the monitor, but also on our eyes and what you are doing with the PC...^IFV
