sorry i dont understand your explain at all but rgb and luma arent the same, 1084s hace some switch on the back, try it with the correct position.

yeah i know , i use luma for c64 and rgb for amiga's , when i wish to use amiga's i click back on rgb button and have amiga's if i wish to have c64 i turn off that button and have luma signal , but there is no sound on luma and rgb , when i play on c64 with luma have good picture no sound, when i click use rgb with amiga's i have sh.t picture (like on video i send up) and no sound like on luma

Dont know... maybe the cable, speakers... try with headphones connected to monitor (maybe speakers dont work) or use another sound source (mp3 player).

is this two cable are same , i have this one





i think that cable is broken so i will buy another i think monitor is OK because i have normal picture with c64 (luma)

  is this cable same like mine on first picture




I ask is cable same because the pin on smaller part of cable are not same on mine (first picture) and on this on second picture so maybe i have bad picture on rgb is because of that pin's or my cable is really broken and don't work , or rgb port on monitor 1084s don't work
