Maybe you are running on a PC and using sRGB as your color space.  If so, 
a color managed display is less important.  I run on a Mac with a gamma 
1.8 monitor, and I prefer to use Adobe RGB as my color space.  With 
VueScan set to Adobe RGB, images appear very different than how they 
appear in Photoshop: the VueScan version is very flat and desaturated.

I've figured out a workflow that gives me a somewhat more useful display 
in VueScan.  I set color space to Apple RGB and gamma 1.8 for my first 
look at the scan.  I set crop, exposure, white point, black point, 
brightness, and filter options, using Prev Mem and Scan Mem to check 
results in Apple RGB.  Then I change to Adobe RGB and gamma 2.2 (keeping 
other settings the same), and I do a Scan Mem to write the final output 
file.  This two-space two-step takes extra time, and it still does not 
give a really good match with what I see in Photoshop.  But it's the best 
I can do with the current version of VueScan.
