Dear all,

I have a problem overclocking my sony bravia kdl 22ex553 i'm using a HDMI connection, it says "unsupported signal. Check your device output." on the tv itself whenever i change the refresh rate to anything greater than 60 using CRU Does anyone have an idea on how i could fix this problem? I'm hoping to be able to get this running at 75Hz but even 61Hz gives the error , does anyone know a solution to this or have any ideas? this is only my second post on this forum and sorry for bad formatting. If you need any more information i will post it for you.
