The ornamental design for a combined monitordisplay and disc player, as shown and described.
FIG. 1 is a perspective view of a combined monitor display and disc player showing my new design;
FIG. 2 is a front elevational view thereof; and,
FIG. 3 is a left side elevational view thereof.
The even broken lines showing in the drawings illustrate unclaimed portions of the combined monitor display and disc player and form no part of the claimed design. Dot-dash broken lines define the boundaries of, but are not included in, the claimed design.
