I can see what you're saying Doug, but to me reducing the contrast of a display in order to reduce peak fL seems a clumsy way to do it. I know that not all displays have suitable controls for this, but reducing the backlight on an LCD TV or closing a manual iris on some projectors seems a much neater way of doing it and in some cases will increase on/off contrast too.
I've never owned a plasma display, but is there no equivalent control to an LCD backlight? I plan to replace my existing LCD TV at some point and would likely get a plasma next time, but apart from using some bias lighting to help guard against eyestrain, I'm a bit reluctant to reduce the fL by the contrast control unless absolutely necessary. DO the various modes like THX, movie, etc just reduce the contrast as well or do they do something else?
