Apologies for not replying sooner my settings are the default user 1 settings.
Gains RGB all set to 100.
I was going to purchase a calibrator however as the days/weeks went by I adjusted and started to enjoy my monitor, which to me is the most important part of the purchase instead of seeking beyond perfection.
Gain: Red 100; Green 99; Blue 98
What contrast result did you receive, and what software are you using for calibration? I was only able to get 923:1 using dispcalgui + argyll.
Verification was done with Basiccolor 5.
edit: I can't read apparently, didn't see the part about lacking a calibrator.
