It’s more complicated than that. At this point, a Dell/Alienware branded monitor with an LG panel is preferable over an LG branded monitor with an LG panel. Even if Dell doesn’t make any panels, the parts they do contribute and their quality standards can make their monitors better quality than other brands that do make their own panels. I think it’s the same with Apple. They don’t make panels either but their monitors are generally regarded as high quality, if overpriced.
