Default USB/Video: How to tell if a screen resolution is supported

I'm looking at buying a new monitor, either 3840x1600 or 5120x1440 (not sure yet). I would need a new USB->video adapter to hook up either one of them to my computer. DisplayLink products are prominent.

How can I tell whether an adapter I see for sale would support those resolutions, if the manufacturer hasn't provided a list (which is the normal case)?

In particular... I see a mention of an adapter that supports 3840x1920. Is there a good chance that that adapter can also do 3840x1600?

If you can determine the DisplayLink chipset within the product you wish to purchase, you can use that information to determine the resolutions supported by referring to this table -> https://support.displaylink.com/know...lution-support

That link says "The table below documents the maximum supported resolution".

So... with the numbers I gave, I am indeed within the maximum supported resolution (3840x1600 is within 3840x1920.) Does that mean there's a good chance that the adapter/the chipset will indeed work for the monitor in question?

I don't want to get something chunky like a 3840x1600 curved screen shipped here unnecessarily...

Thanks.
