I've been using the hdmi outfut on my laptop for 8 months now and no problem. I recently went on holiday for two and come back to find then when i connect my laptop via hdmi the picture has loads of green or white specs around teh screen and and green lines all of which are flashing. some the picture is just a load of multi colour lines. I've tried two different screens and 3 different cables but the result is the same. model is: vpcej2c5e
