Hey David,
I just purchased the 50″ 9UK from visual apex last week.
In my research/prep work in anticipation of its delivery last week, I documented some things (screensaver info too)
“Go to screen saver menu, turn on wobbling in screen saver menu, number 2 setting. (this is a pixel shift)”
Are you doing the 100 hour burnin with the burnin dvd image from avs?
