True, and with the 8560E, it isn't even really lower resolution,
but with the 8566B, it is very much so. Measurement accuracy is
hardly the problem, appearance is the problem, and that is of
course subjective. The cursors will still hug the waveform at
the higher resolution level, and will still be read out to the
ultimate accuracy of the 8566B.
We will see. I am hoping that the flashy display with all of
its colors will make it just seem normal and right.
The big difference between what Xu Wang has seemes to have done,
and what is done in many graphics situations is he is drawing
full intensity lines of single pixel width. When the line is
slightly off vertical, or horizontal, you see a stair step
approximation. If there were a little more graphics power in
use, the traces could be made wider, with variable brightness
across their width. So, even though they are wider, they would
appear to be smoother and narrower.
An example of this that you may have seen on your computer
happens when you scan a document. If you use the line-art
setting, where the pixels are either on, of off, you need a
fairly high resolution to avoid seeing artifacts on the text...
say 300 to 600 dpi. If, however, you use grayscale, you can
get something that appears to be higher resolution while using
only a paltry 75 dpi.

Yes there is a theoretical downgrade from a 1K x 1K

Xu has done a remarkable job at anti-aliasing the trace and I'm well
pleased with the beta version I have in my 8568A.
As for the lower resolution, if I'm reading a value, I'd use a marker
anyway...
