Good to know the name, I’ve seen it invoked a few times.
In fact, I had this recently at work where I questioned a decision only for them to retort with one similar characteristic which a prior suggestion of mine shared. This was also a modal fallacy as they only used that one characteristic to come to a conclusion about both.
You also see it all of the time in politics unfortunately, a lot of “yeah but you also…” where we should be hearing good justifications.
OP:
Jokes aside, I think what you’re looking for is called a multiviewer. You want a 2x1 multiviewer to get a view like that, though it might be split vertically rather than horizontally.
