My first question would be, you asked for 110 but if you look in current system profile is that the value you actually hit?
The suggestion about lower luminances had nothing to do with damaging video cards. The issue is whether you can drop the luminance of an lcd below a certain level and still get good stable results. We're not talking damage here, we're talking stability and accuracy. That will depend on your particular monitor and what it will produce.
But first lets confirm that you are actually hitting your target.
Seems if the OP used a calibration device to actually read the brightness of the display, and modified the brightness so that shows a value of 110 (using a good software tool), it's pretty confirmed the target luminance is being achieved.
I'm not sure where you can confirm this looking in a system profile .. the computer doesn't know how much light the monitor is delivering, only what % of the maximum light is being delivered.
As to the question which is better, to increase the light hitting the print, or decrease the brightness of the display, it seems if you dim your display too far, it may get challenging to use. Not because of stability ... just not enough light coming out for your eyes. I don't think turning down the backlight has any adverse impact on stability ... it may make it better.
If your viewing station has adjustable brightness, then certainly setting up a luminance target, and adjusting the brightness of the viewing station to match the monitor should work well. The goal here isn't just to have a particular "luminance" .. it's to try and get a similar "white" from the screen as compared to an unprinted piece of paper in your viewing station.
If you can't adjust the brightness of the viewing station (which is more common I believe), then luminance values are pretty irrelevant .. your only choice is to adjust the brightness of the monitor to match the viewing conditions.
