Mark,
Diglloyd’s tip is found in the section entitled “D800 / D800E Live View Tip for Better Definition” which is part of his extensive review of the D800 and, unfortunately, is located in his ‘Diglloyd Advanced Photography’ (DAP) section which is in fact only available to subscribers. However, basically he recommends doing what I mention in my comments above, namely to increase the sharpening setting to ‘9’. He also suggests creating a custom Picture Control setting (he used Nikon’s Camera Control software to do the editing) with the sharpening set to maximum (9). Lastly, he offers a .zip file with this custom setting which one can load on to the already existing pre-sets. Basically that’s it, in a nutshell. Lest I provoke Lloyd Chambers’ wrath by divulging information which is only available to paying readers, I do find his blog extremely informative and well worth the subscription price. Hope this helps.
Best wishes,
Larry
