Connect the audio cable from the PC to the
Audio input on the TV.(Audio cables are not
included with the TV).
If you use too long an RGB-PC cable, there may
be interference on the screen. We recommend
using under 5m of the cable. This provides the
best picture quality.
We recommend using 1920x1080, 60Hz (Only
19LU5***, 19/22/26/32/37/42LH2***:
1360x768, 60Hz) for the PC mode, these
should provide the best picture quality.
HDMI mode supports PCM audio format only.
If the Audio setting is set to
Dolby/DTS/Bitstream in some DVDP/STB, make
sure to change the setting to PCM.
