I'm trying to connect my iMac (Intel) to a 42 inch HP(Hewlett..) TV, and the TV has a PC slot, which the manual says is a VGA input. After reading the iMac manual it says I need a mini-dvi to vga adapter, but the only one I can find is made by Apple. After reading some reviews it seems that the Apple product is actually very cheaply made. Is there an alternative to do this? I just want my iMac picture to appear on the bigger screen. Thanks in advance!
