Here is the situation (seen similar threads, but not really hitting exact issue):
I have two computers, both identical, with identical Dell P2314H monitors at 1920 x 1080 resolution. If I use Logmein while the host computer is physically attached to that monitor, all displays perfectly and matching. However, if the host monitor is disconnected (unplugged), then the next time I connect the same two computers through logmein, the resolution is maxed out at 1600 X 1200. However, if at that time, I then use Remote Desktop instead of logmein, then I can get the 1920 X 1080. So this does seem exclusively a Logmein limitation, not a graphics card one.
What I'm trying to accomplish, is to have the host computer not have a monitor attached to it and get the 1920 X 1080 resolution. Yet, I don't seem to be able to accomplish this with Logmein Pro, but I can with Remote Desktop.
By the way, if there is not a work around... I basically have to cease using Logmein and have our users VPN and remote desktop. Or maybe see if somebody else has a service that doesn't have this resolution limitation.
