I think you're right & I'm wrong, Sorry,
Here's what I'm thinking I see now,
We have 4 monitors in a row, The order we see them in goes from right to left, The first two are G-sync compatible, both have stickers stating the one on the right is a 27" 4k model and the other is a 27" QHD model. The next two monitors are both unvalidated. It looks like the third monitor from the right to left is a 32" not an ultrawide as I thought & the fourth monitor is a regular ultrawide as you said.
At 1:01 we see the Gsync compatible monitors alongside the first non-validated monitor & the non validated looks a lot wider which is why I presumed it was an Ultrawide, but now that I'm looking closer I can see that the panel itself is also taller so it's not just a width difference it's a height difference as well so it must use a 32" panel.
Now I'm wondering what resolution the 32" monitor is? There's no sticker on it and Nvidia's complaint is that the picture looks blurred, Could that be in part because it uses a 32" panel that doesn't look as sharp as the picture on the two 27" models which where stickered as 4k and QHD.
Stop the video at 1 minute & 1 second & tell me what you think.
I think Nvidia are trying to obscurate the truth regarding how adaptive sync compares to G-sync by making it all about monitor quality which we've all known is an issue from the start, an issue that's down to the monitor makers not how well the tech works.
