Do you have enough slack in the wires to move them that far?
If they are long enough; I can think of a few ways.
The first, is to cut out a piece of sheet rock, drill holes in the studs and move the wires over. Put the rock back, spackle and paint.
The second, Greenlee makes a flexible drill bit, about 4 ft long.
Cut out a hole for your low voltage trim ring. Use that opening to insert the bit and drill the two studs.
The drill bit doubles as a snake.
The third, Wiremold makes Cable raceways for your wire.

The fourth, get a bigger LCD, that will cover the two studs; and leave the wires where they are.
