G
analogue and digital RGB simultaneously, connect
only one of either RGB or HDMI IN (or HDMI/DVI
IN) to display the PC output on the TV.
If the graphic card on the PC does output
G
analogue and digital RGB simultaneously, switch
the TV to either RGB or HDMI; (the other mode is
set to Plug and Play automatically by the TV.)

interference on the screen. We recommend using
under 5m of cable. This provides the best picture
quality.
