Hi all:

I have a v5100 setting on extended desktop. Out of curiousity, I ran a x11 perf script between the single display mode and the extended desktop mode and noticed that the latency on the extended mode is much bigger (by many orders of 10's). I am beginning to wonder if this is a design related issue, and if any of you have a NVIDIA Gforce or Quadro card set on twinview, can you please run the following script in both (1) Single (2) Twinview mode and post the results?
