hey guys

I just plugged the tv for my arcade in via s-video and i booted her up and I noticed Several Problems right off the bat.
firstly: the screen flickers. i tried to change the refresh rate on it through windows but it will only do 60Hertz. is there an way to reduce the flicker of the screen?
2nd: the picture is off center and bent. i notice this happens when you move a crt pc monitor around but you can just change the picture using the buttons at the front of the screen. what can i do??
3rd: the tv lets off a high pitched noise. i realise that when it is against the wall (it has an open back) and has glass in front of it it will be substantially quieter but i dont think it with silence it enough.
thanks
