new 20PF5320 on most 16:9 broadcasts i get a small black horiontal border at the bottom of the screen i tried all of the settings and i can't get rid of it (the manual mentions a 'fullscreen' aspect ratio setting but i cant find it while cycling trough all the available ones) is it a faulty lcd (or service setting?) or something else? the other 32" loewe crt tv doesnt have this problem!
