[quote=captfbgnet;1126599]SECOND POST: Hoping for an answer...
All worked well until I upgraded to the EVGA 9500GT 512 mb Nvidia card and
latest nvida drivers. No problems with card or software install (other than
a quick message about hibernation not working or something similar). All
power options checked and rechecked and also advanced power settings checked
and rechecked. Have re-installed monitor and updated Nvidia software since
initial install and also tried a second DVI port on the card. No help. Also,
under Device Manager/Action I uninstalled (not deleted) driver then did a
'check for hardware changes' hoping to refresh (find) the driver (?) issue.
No joy. Also, SFC scan found no problems.
The monitor error box comes on at the initial 'sleep stage' saying "no power
connection, check for loose cables, etc." If I immediately cut the power off
to the monitor, then on again it detects the sleep stage and immediately
goes into that state and awakes properly on the movement of the mouse or
keyboard. An annoyance or screen burn issue if I forget to cut power to
monitor when I finish. Finger pointing is the name of the game when I call
EVGA, Nvidia and LG (monitor)
Anyone of you experts have any ideas? Thanks in advance.

Apparently when one updates Nvida software and or card and when using the HDMI connection, the monitor thinks it is attached to HDTV NOT HDMI and thus the problem. The 'script' worked perfectly for me and after nearly a year, I have the fix. Hope others with the same monitor will be helped.
