Good question, I´ll look for it.

There is nothing about this in the settings or in the manual.

Thanks for checking! Then either Rigol have chosen different ways to show the measurements + traces on the DHO800 vs 1000 -- which would make some sense given the different screen sizes. Or maybe the DHO800 version is the newer one and will show up on the 1000 with an upcoming formware update. (Or it has already and I was looking at older screenshots and videos.)

I had looked at my "old" screenshots from February, I think that's exactly why.
You simply have enough screen width, with the 800 the boxes were not compressed and instead the window with the measurement results was made transparent.
But it's true, that could be taken over from the small model.
Something for the wish list...
@others : Here (starting at appx 1:15) you can clearly see the compression when activating the sidebar:

The ultra acquire mode still leaves me baffled.
You can conjure up impressive images on the screen with it, but somehow that's about it.
I had sent various glitch signals to the scope, but they were more noticeable in normal mode and with the appropriate triggers than in ultra acquire mode.
On the contrary, the glitch is not visible in this mode.
If no one can provide me with a corresponding picture/test to the contrary, I will check off this mode as a gimmick.

I think the idea is to see events "in context", ie. you can see the event and what came before/after it all on the same screen (in 3D or whatever).

But in most time domain applications, you can also do that paging through conventional memory segments one at a time, and get a much better view of the signal in each segment.
I would agree that UltraAquire is mostly a gimmick, although you can certainly find specific use cases where the visual correlation of the neighbouring events is helpful. Analog TV images might look nice as a 3D landscape, or topographical scans or the like. :)
EDIT: Once I get to actually use my new DHO1000, I will dig out my old homebuilt scanning tunneling micoscope! I was always too lazy to write proper PC software to visualize the acquired scanned profile, but UltraAquire should handle that job nicely. 8)
