Final answer:
The rendered pixel size affects the image resolution on an LCD monitor, with more pixels leading to a higher and sharper resolution. Image brightness and image contrast are influenced by other factors, and image size can change with settings and scaling but isn't directly impacted by pixel size.
Step-by-step explanation:
The rendered pixel size of an image on an LCD monitor will have a direct effect on the image resolution. Image resolution refers to the number of pixels used to display an image. More pixels mean more detail and a sharper image. On the other hand, if you decrease the number of pixels for a given area, the resolution is reduced, and the image may appear less sharp or detailed. Image brightness and image contrast can be affected by other factors such as backlight strength and voltage applied to the liquid crystals, respectively. However, the actual size of a pixel doesn’t directly alter these attributes. Similarly, while the image size can change based on screen settings and scaling, it's not a direct result of individual pixel size.
