Hi there,
First difference between the 700D & 700DSL is contrast ratio, 700D spec "Mega DCR (Static 3000:1)" 700DSL "Mega DCR (Static 1000:1)"
Second difference is power consumption 700D spec "44W" 700DSL spec "39W"
Third difference is standby power consumption 700D spec "1W" 700DSL spec "0.5W"
Fourth and final difference is the price 700D price "$379.99" 700DSL "$329.99" both these prices are from newegg.
The Samsung S23A700D is the better monitor between the two
P.S
Getting my Samsung S23A700D tomorrow woohoo
