Just FYI, I managed a USB DOS boot and flashed the video card with NVIDIA Source BIOS Version: 62.94.4B.00.18 from http://www.gigabyte.com.tw/Support/v...ProductID=2879
. That resulted in a scrambled video display. I managed to re-flash the previous BIOS (62.94.2c.00.00) by blindly typing in the necessary DOS commands (phew!) and everything is back to working, but the LG is still not detected unless "warmed up".
