Okay, here's an odd-stupid question. On a LCD, brightness, contrast etc can be configured either via the monitor's menu or using some software. Is there any difference in how either of these settings affect the display's lifespan?
Some background: My Dell 2209WA starts "buzzing" unless I manually set the menu-brightness to 99% or 100% (it is a reported problem with this model). After doing so, I re-lowered the brightness with Redshift.
Now, if the monitor's menu shows "99%" and the software declares "0.5" then what is the monitor's actual brightness? Are the hardware settings still somehow superior? Should I be worried about the "99%" with regard to the monitor's lifespan?
(Obviously, this should be the same as setting your headphones' volume knob to maximum and then lowering volume via the sound card driver. But I don't want to screw up an e-IPS monitor, so I still took the courage to ask :)
Thanks for any explanations!
