I have my 92840 on a 15" stand and it is definitely a compromise. Since I just blew through my 2012 AV budget with a Darblet and a Lumagen Radience XS with 125 point autocal the 10 to 12" stand will have to wait till spring. I am going to custom build something that is much more functional than anything else. I will probably not have a bottom shelf and put my components directly on the floor. This should allow me to have my center under the display as I do now. You give up a good bit of color saturation and brightness when you get off axis. There is definitely a sweet spot at the screen's center.
