problem s nastavenim obrazu ces tv-out

podla netu som nastavil xorg.conf ako som vedel a skusal som vela kombinacii roznych nastaveni ale stale nevidim na telke cely obraz ale len jeho "zvecceninu"
proste asi tak akoby som na telku poslal rozlisenie 1280x1024 ale zobrazilo mi iba 1024x768
ked v xorgu v metamodoch nastavim aby mi z primarneho rozlisenia z crt vsetko prekonvertovalo na 640x480 pripadne 800x600 obraz je obrovsky a nevmesti sa do TV.. ket toto iste nastavim ale tak aby mi vsetko prerobilo na 1024x768 obraz sa us takmer vmesti na TV.Ale ked us nastavim 1280x1024 tak us taketo rozlisenie nezobrazi TV a vidim len cierno.. keby ho zobrala tak by to bolo OK.. prosim poradte mi co mam spravit.. obraz c xorgu klonujem,, tv mam staru ovp 70palcov
este posielam tu podstatnu cast z xorgu
PS. konfigurujem to na debiane
