Does the graphics card have any effect on image processing?
The server graphics card is used for image resizing and in font smoothing (antialiasing). When a low specification card is used it can restrict the maximum image size that can be processed. Images that are too big for the graphics card to resize will appear cropped when reduced, or a smaller copy of the image will be shown at the top left of a plain background when the image is enlarged. Font smoothing is rarely a problem as this is usually supported by even the lowest specification graphics devices.
