You should check the scaling options for your TV. On my TV there are options like "Full" "Wide" "Full Wide" and "Full Pixel". You would want full pixel, so check your TV settings for something that sounds more or less the same, or says that it doesn't do any scaling of the image.
thanks for replying
can it be also the configuration in the notebook?
the notebook got to Video cards, first is Intel HD integreted onchip, second is nvidia 310M .
it uses nvidia optimous technology to change between them ,..
so could it be in windows, intel or nvidia control panel configuration
