Well i was hopeing that the new driver release would resolve this issue . it is still a problem and nothing new to report.
quick summary
system is set up with 2 monitors
1 a dell e22w8fwp 22" lcd monitor
1 vizio vw32l 32" lcd television
both configured for 1680 x 1050
and configured for mirror mode
using the new nvidia 257.21 drivers
would like to see this fixed.
