Hi All
First post here, i guess that qualifies me as the complete noob :D
I have the following stuff:
Samsung HL67A750
Sony Mini surround system HT-SS2300
Sat. connected to a Full HD Scaler Box
PC with video card 8800GT and a mobo with the Bernstein audio module on board. (mobo is dfi lanparty ut x48 T3RS )

Sat. connected to the scaler and scaler to the Sony ampli, works great.
I have 2 problems:
1) When connecting PC to the TV's PC port (DSUB) , the image looks as if it lacks enough refresh rate ( bright colors flicker like crazy ). Tried connecting to the Scaler pc port, exactly same output ( makes sense since scaler has also DSUB connecion ). How do i connect the pc to the tv to get the best quality possible? What resolution should i set? Should i connect directly the pc to the tv's hdmi-dvi port using a dvi to hdmi cable?
2) Assuming connecting dvi to hdmi cable to connect pc to tv fixes the problem, how do i connect the sound from pc to the Sony Amp. then?

Thanks for your help
