i can see the power board for the monitor.it has like contrast and brightness on the monitor itself.
i found the vertical switch but,i cant seem to find an horizontal one.theres only 2 buttons visdible on that remote board,one adjusts the vertical the other color.i am at a loss here,its either something so obvious but,i fail to see the horizontal button.

i took a pic so you can see better (sorry for quality)

theres from left of board to right,on the left corner is color,on the little board is vertical hold,then on the white thing with the metal round it is a sharpness and i think focus or contrast.
there is a switch near the vertical hold board,just behind it,if i switch it i get loads of lines.
there is a green connector with B G R GND VS HS there is a wire thats been solder to HS.i take it vs/hs is vertical and horizontal sync?i cannot see anything else,with my luck it is probably something so simple vas well.
