We claim, the ornamental design for a monitor, as shown and described.
FIG. 1 is a perspective view of a monitor showing our new design;
FIG. 2 is a front elevation view thereof;
FIG. 3 is a rear elevation view thereof;
FIG. 4 is a left-side elevation view thereof;
FIG. 5 is a right-side elevation view thereof;
FIG. 6 is a top-side plan view thereof;
FIG. 7 is a bottom-side plan view thereof;
FIG. 8 is a rear perspective view thereof; and,
FIG. 9 is a perspective view thereof with a keyboard.
The oblique line shading of the monitor as shown in the Figures represents a relatively transparent, translucent, or light reflective surface. The remaining surface treatment of the monitor shown in the figures forms no part of the claimed design, as a monitor according to the claimed design may have any surface treatment.
The broken lines illustrating portions of the monitor are for environmental purposes only and form no part of the claimed design.
