I have a Aspire 6935G with a Nvidia 9600m Gt TurboCach graphics card.? It has 3GB DDR3, 320GB HDD, Duo processor T6400, It is full HD and has a blue ray player and plays blue ray disc with no problem, but when i try to play BR with an HDMI cable to my HD TV i get the following message, "Incompatible graphics driver.Please make sure your graphics drivers meet minimum criteria requirement. Ordinary DVD'S play via the laptop to the tv, i have checked drivers and as far as i can tell they are the latest drivers, any help, ideas, please. Many thanks Mike
