I did what you guys are explaining with the "y" splitting the signal to the 2 monitor. My video card was damaged due to different resolution of the tv's at the venue I am playing now. At least, that is what the techs told me when I went to the computer shop that repairs all my computers. Since it is a laptop it was very expensive. They have to replace the whole motherboard. $465 to replace it
. After that, I won't risk my laptops again with that type of connection. The owners then got me a video matrix with 4 inputs and 8 outputs. I connect my laptop to that equip and it takes care of all different LCD's around the place. Since the owners did not get all the LCD's at the same time they have several brands and sizes around. In that particular bar, they have 4 LCD's around and the one that I own to display lyrics to the singers, so they are five and sometimes they use the smoking area ones so sometimes it goes up to 7 LCD's. I don't know if what the guys at the computer shop told me is correct but want it to share with you all. Maybe there is a limit on how many displays and/or resolutions a video card can handle
