A system for displaying images comprising: a video source; a projector coupled to the video source, the projector configured to emanate a combined beam of coherent and incoherent light onto a screen or a wall; the projector comprising: an incoherent light source; a coherent light source; and a circuit arranged to receive video signals from the video source, wherein the circuit is arranged: to convert the video signals to a format suitable for display by the incoherent light source and coherent light source; to drive the incoherent light source while concurrently driving the coherent light source, so that the incoherent light source operates in concert with the coherent light source to produce a combined beam of light, wherein the combined light beam includes a wavelength from the incoherent and coherent light sources that substantially matches; and characterised in that the incoherent light source and the coherent light source are driven by different portions of the video signals, in that the coherent light source is driven by a chrominance portion of the video signals, and the incoherent light source is driven by either a luminance portion of the video signals, or the luminance and chrominance portions of the video signals. a video source; a projector coupled to the video source, the projector configured to emanate a combined beam of coherent and incoherent light onto a screen or a wall; the projector comprising: an incoherent light source; a coherent light source; and a circuit arranged to receive video signals from the video source, wherein the circuit is arranged: to convert the video signals to a format suitable for display by the incoherent light source and coherent light source; to drive the incoherent light source while concurrently driving the coherent light source, so that the incoherent light source operates in concert with the coherent light source to produce a combined beam of light, wherein the combined light beam includes a wavelength from the incoherent and coherent light sources that substantially matches; and characterised in that the incoherent light source and the coherent light source are driven by different portions of the video signals, in that the coherent light source is driven by a chrominance portion of the video signals, and the incoherent light source is driven by either a luminance portion of the video signals, or the luminance and chrominance portions of the video signals. an incoherent light source; a coherent light source; and a circuit arranged to receive video signals from the video source, wherein the circuit is arranged: to convert the video signals to a format suitable for display by the incoherent light source and coherent light source; to drive the incoherent light source while concurrently driving the coherent light source, so that the incoherent light source operates in concert with the coherent light source to produce a combined beam of light, wherein the combined light beam includes a wavelength from the incoherent and coherent light sources that substantially matches; and characterised in that the incoherent light source and the coherent light source are driven by different portions of the video signals, in that the coherent light source is driven by a chrominance portion of the video signals, and the incoherent light source is driven by either a luminance portion of the video signals, or the luminance and chrominance portions of the video signals. to convert the video signals to a format suitable for display by the incoherent light source and coherent light source; to drive the incoherent light source while concurrently driving the coherent light source, so that the incoherent light source operates in concert with the coherent light source to produce a combined beam of light, wherein the combined light beam includes a wavelength from the incoherent and coherent light sources that substantially matches; and
