You can spray paint the back of the screen to make it opaque, (or indeed any colour.) I used a regular black satin acrylic from a car accs. shop. Just be careful to mask it off carefully. BTW even if you use matt paint the outside will look gloss because of the smooth screen. The choice of matt, satin or gloss only effects the look of the inside. Its quite easy really, just be careful to get all the dust and any polish off the screen as it will show up Dion
