NOTE
 
► Avoid keeping a fixed image on the set’s screen 
for  prolonged periods of time. The fixed image 
may become permanently imprinted on the 
screen; use a screen saver when possible.
 
► There may be interference relating to resolution, 
vertical pattern, contrast or brightness in PC 
mode. Change the PC mode to another resolution 
or change the refresh rate to another rate or 
adjust the brightness and contrast on the menu 
until the picture is clear. If the refresh rate of the 
PC graphic card can not be changed, change the 
PC graphic card or consult the manufacturer of 
the PC graphic card.
 
► The synchronization input waveform for Horizontal 
and Vertical frequencies are separate.
 
► We recommend using  1920x1080, 60 Hz for the 
PC mode, this should provide the best picture 
quality

.
 
► Connect the signal cable from the monitor output 
port of the PC to the RGB (PC) port of the TV or 
the signal cable from the HDMI output port of the 
PC to the HDMI IN (or HDMI/DVI IN) port on the 
TV.  
► Connect the audio cable from the PC to the Audio 
input on the TV. (Audio cables are not included with 
the TV).
 
► If using a sound card, adjust PC sound as required.
 
► If the graphic card on the PC does not output ana-
logue 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 analogue 
and digital RGB simultaneously, set the TV to either 
RGB or HDMI; (the other mode is set to Plug and 
Play automatically by the TV.)
 
► DOS mode may not work depending on the video 
card if you use an HDMI to DVI cable.
 
► If you use too long an RGB-PC cable, there may be 
interference on the screen.  We recommend using 
under 5m of cable. 
This provides the best picture 
quality.
