Greetings, Flipped my Acer V193 19" [which is crap btw] to portrait and switched the mode via Nvidia software just to try it out. Things seem to be slow. That's the only way to describe it. Specifically, when I played around with Quotetracker pull downs in trading section things seemed to take an extra second to "redraw" . Don't know if that's the word for it. Just seemed slow. Stopped as soon as I went back to landscape. Does being in portrait mode use more resources or something? Thanks, V.
