What people are saying

Rated 1 out of 5 by from I bought this monitor along with a second one to use in a laptop dock situation after support informed .e that the monitors are supported to work thru a dock hooked to a laptop. In fact they do not work in such a situation. So far, LG support can't or won't stand behind their initial support for this configuration. So, I am not satisfied at all with my purchase. Support said they would escalate this up to some executive level for resolution. So far nothing back except advertising to buy more LG products.

What are my options for adjusting the screen brightness with a Macbook? Will I be able to use my computer's hot keys, the OS system settings, LG's own popup window, and/or actual buttons on the monitor itself?
