anybody could help me on my setup? before this i was playing my PS3 on my LCD TV..

then now i bought Acer Monitor X203H for PS3 in my room..i also used the HDMI to DVI converter..

the problem is:
1. it says it doesnt support the input..i cant view the PS3 menu..but i can play games when it loads..
2. when i hook up my speakers to the Audio Out of the LCD Monitor it doesnt have any sound at all..even if i dont hook up my speakers, it also doesnt have sounds..the LCD has built in speakers btw..

any help would be much appreciated..
