, the TV will not expand/stretch the 235 white in the input to 255 white (what it displays). This means your input signal does not map properly to what the panel displays.
maybe it's the 16-235 rgb that's confusing me, not sure. but when I display video I get the same peak brightness as when I display games.
I've calibrated my display for both video and gaming, and I get basically the same image as long as both the source and display are set to the same range.
as Zoyd commented above, what you're showing isn't really evidence that 235 is more dim than 255. I would also add that it's just showing you've calibrated for white to be higher than 235. I didn't want 50ftl, so my test patterns do look like that, in order to get 'white' no brighter than 32ftl, there's obviously a lot of wtw info that could be displayed by the display.
but, when I play games, and have 0-255 sent to the display, and switch it to 'normal' I STILL have 32ftl for whites.
if I wanted to get peak brightness from the display for video, I would adjust the contrast so that the bars don't flash above 235. most ppl don't set it that high, but that's a choice, not a limitation
