MarshallR@ASUS....thanks for your response and I'd appreciate it if you can look into the question about disabling the NB monitor. The G750 JS is also used for non gaming activities in which both monitors would be required. Is it GSync that may require turning off the NB monitor and if so, would then turning off GSync allow for an extended desktop.
Got the G750JS to replace a G73JH and so far it's been a great upgrade.
Thx.
