I am using a Gigabyte Ga-m68mt-s2p right now for a motherboard and I was using a Ati Radeon 4600 hd series graphic card. I replaced my graphic card with my new gigabyte ati radeon 7750 (GV-R775OC-2GI) and I am getting a blank screen on a regular computer monitor but when I use my tv ( it is my main monitor) I get an unsupported message. I just need to know if these two products are compatible and if they are if there would be a reason why I am getting no video or anything when trying to use this new card. Any help is deeply appreciated.
