There are people who may point out that imagesetting starts at 1200ppi and can go up from there, so maybe this LG display is warranted. The flaw in that logic is that imagesetters are 1 color B&W (Ok, just B) or 4 color CMYK devices (we'll ignore 88-175ppi linescreens for images here) but they are just that: 1 color per pixel. They need the extra resolution to make those "all-on" and "all-off" pixels look like smooth lines at reading distances because our eye-brain system is very attuned to contrast boundaries. Computer & phone displays have 16M colors per point and can create smooth, sharp images at about 300ppi.
