Is higher resolution better quality?

As www.pforprojector.com write. Higher resolutions mean that there more pixels per inch (PPI), resulting in more pixel information and creating a high-quality, crisp image. Images with lower resolutions have fewer pixels, and if those few pixels are too large (usually when an image is stretched), they can become visible like the image below. The maximum resolution of a monitor or printer. In an LCD display, the native resolution is significant because, unlike older CRTs, which could display several resolutions at a high quality level, the native resolution (highest resolution) of a flat panel is generally the sharpest.
