Hi i jsut bought a 21 inch monitor for my cab., since i didnt like the way the frontend looked on a tv. but now i cant play some games because once it starts up is goes to a scratchy screen and says invalid freq. i read in another post that there is a way to fix that but it didnt go into to detail on how to do that. Any ideas? I would go back to the tv but its almost impossible to read the game list in mamewah. Im using a geforce fx 5500 agp 8x video card. any ideas?
