Nvidia GeForce 9300M GS hdmi help - problems

[djskarpia]

hi everybody, i'm currently running snow leopard 10.6.4 in my fujitsu amilo pi 3540 with these hardware:

 

- cpu intel core duo t5800

- chipset intel pm45+ich9m

- wifi: broadcom airport 4311

- graphic card: nvidia geforce 9300M gs

 

my problem is that hdmi out works ... but when i set 1080p as resolution it doesn't appear fixed with the tv screen and there are black stripes on the two sides...

 

how can i fix this? if i choose 720p it is good but i can't see my films in full hd definition.

 

another big problem is the sound: i've installed the voodoo hda kext... but i can't enable hdmi out sounds... i don't know how to do...

 

for graphics i've used during the installation graphicenabler with pci efi 10.6 bootloader and then i've installed over without delenting previous kext the NVENABLER kext... same things...

 

please help me! thank you
