hawarren, my monitor is a Gateway XHD 30" LCD.  And I should mention that I'm a little disappointed in the GC in Poser Pro.  More than likely I'm doing something wrong, but so far, I can't solve the problem .  The results of GC using the node setup in Poser 8 versus using the one button GC in Poser Pro give me different results.  Everything seems to be setup properly, but I get a slightly redder tone and reduced specularity in Poser Pro.  I've tried it in PoserPro with the normal node setup and I've tried it with the GC nodes in place changing the 2.2 to 1.0.  Either way, I get the same exact results: a render that is not a duplicate of the render in Poser 8 with the Gamma Correction node setup.  Shouldn't it be?  If math is about precise measurements, then I'm left scratching my head, wondering if someone missed a decimal point when configuring Poser Pro.  Like I say, more than likely I'm missing something very simple, and hopefully I'll find the problem.  But as it stands right now, I'm lost for an explanation of why there should be any difference, however slight, in the renders.
