Hi! I just got my new external monitor with full HD resolution, connected to my laptop, also with full HD. But when I try to play HD content on one of the monitors the movie doesn't play smoothly. If I use only one screen there is no problem watching the movie in full HD. My computer is a Lenovo W510 with a Core i7 processor with Nvidia Quadro FX 880M graphics card, and I used VLC to play the content. I usually don't need to watch HD content on one screen while working on the other, but my question is if it is normal for a computer like this to struggle with HD movies when two monitors are active?
