Don't waste your time or money

Either one, or the other, then I have to dick around with unplugging and plugging at just the right time to get both monitors to to work with the lid down

LG is sending me a refurbished one and is sending it 'advance' so I don't lose all the time of mailing the old one back to them before they mail me the new one

My all time favorite 27" monitor by far.
