I don't have 1000xHD to test.
But here are 800xHD images:
https://www.eevblog.com/forum/testgear/sds800x-hd-review-demonstration-thread/msg5361203/#msg5361203So it does NOT always render traces 2 pixels high. Only when noisy and values are "in between".
It does best with resolution it has.
I'm guessing that 1000xHD does the same.
And again, it is not something you even notice if you don't look for it with magnifying glass.
Really.
Not "defending" anything here, I literally had to go and verify if 2000xHD was rendering this way. I didn't know..
I'm not denying effect is there but really not something you even notice unless somebody points to it.
You literally need to look at it with magnifying glass (real or virtual).
Granted, I wear eyeglasses... So maybe people with perfect vision can spot it with naked eye at normal working distance... But not very likely.
