I have a Toshiba Windows Vista HP laptop connected via it's VGA port to my Samsung LE32R41B LCD TV but it is not working. When plugged into the TV using a 1m VGA cable that came with a separate monitor it works fine. Windows lets me choose a 1368x768 resolution and the Nvidia drivers detect the TV as made by Samsung. However when using a cheap 3m VGA cable and a more expensive 5m Belkin Pro Series cable Windows doesn't detect a TV is plugged into the laptop. As it happens 3m wasn't long enough I need about 4.5m. Looking in the Nvidia drivers it doesn't detect the Samsung TV any more. If I choose "Analogue Source" and set it to 1024x768 (1368x768 is not an option) plus 60Hz refresh rate the TV then detects the signal but only because it happens the TV also supports this. This is more me forcing it to work than being picked up properly. I've also discovered if I plug my separate monitor into my laptop using the same 3m cable it's also not detected. I'd have thought this should work, the monitor supports 1440x900. If I use the regular 1m cable that came with the monitor it's fine. Any ideas why longer lengths than 1m do not work and Windows doesn't recognise the TV any more? Thanks in advance.
