In general, you should set the PC to do nothing and calibrate the video display because PC video "solutions" are frequently whimsical rather than offering the precision and control over important image quality factors we see in modern/current video displays. Or the PC controls may be much more obtuse and unpredictable than controls in the video display. Or it might take multiple controls in the PC "solution" to achieve what 1 control can fix in the video display.
If the video display is calibrated as well as it can be calibrated and there are some residual problems, say the 50% step in the grayscale needs some fixing, then use the PC software to see if you can make the 50% step better. But if you have the video display calibrated with a good gamma (for example) or good CMS (another example), you do NOT want the PC doing anything to either of those parameters -- if 50% is good and CMS is good... you don't want the HTPC messing with either of those parameters.
