I'm running into some display issues in Workstation 9.0.2, but only with a Windows 8 x64 guest (other guests including XP, Windows 7 and Ubuntu all seem to work fine).
I am running 3x 24" wide screen monitors each at 1920x1200. Previously I had been running multiple instances of Workstation but that resulted in an annoying issue that would crash work station every so often so now I am running a single workstation instance in Windowed mode with a Window that results in a VM client area of roughly 4930x1080. This seems to work for me leaving some space on the host for a few applications I need visible.
The problem I noticed today, however, is that Windows 8 (in Workstation at least) seems to have a maximum display resolution(?) that causes it to go completely black and be unusable. I have played around with resizing workstation windows and it seems that Windows 8 "dies" somewhere around a width of 4090 pixels wide (with the specified height). Once I go beyond that width the screen goes black, and sometimes it won't even let me reduce the workstation window width after that; it seems to get stuck and then requires some hoop jumping to get it to go back such as attempting to resizing the window several times or even hard resetting the VM and using a new workstation instance to connect to it. A lot of the time the window will stop resizing as it pops back to the larger size, making it difficult to get the display back. (This issue happens irrespective of whether the desktop is visible or the metro UI is visible).
Through a bit more testing I found that the max size seems to be a function of both the height and width (i.e., if I reduce the height I can go wider) so it seems there is some maximum area that can be displayed that is easily eclipsed on a 3 monitor display.
Something seems amiss here... Has anyone else encountered this? Is it a known issue with Windows 8 guests?
I'm yet to find a comfortable way of working with workstation with multiple monitors that doesn't have some kind of issue associated with it. 
Up until this Windows 8 issue I thought I was close!
I'm attaching a picture to illustrate.
