A centrally positioned lift mechanism for a CRT display housing is disclosed using a gas strut located horizontally with the display plinth. The gas strut operates via a lever to move a flexible roller chain within a guide tube curved from horizontal to vertical to convert from horizontal to vertical motion. The vertical motion lifts the display housing, and a lever operates a strut lock to enable any height to be selected. Proposals to use a single vertical gas strut as a lift mechanism for a CRT housing have the drawback that the strut has to be considerably offset from the center line of the display to eliminate screen distortion due to the mass of steel used in the strut construction, this gives the display a distinct "lop-sided" appearance.
