But on top of all of that, the Amazon product page you linked indicates that this particular adapter is limited to a maximum resolution of 2048x1152 - or 1920x1080, when considering resolutions that are actually in use today - which is well below the S2719DGF's resolution of 2560x1440. Those adapters also require special drivers to be installed, otherwise they don't work at all, so that might have been a problem too. It seems like both of those issues may be factors here - more on that below. The only real times they can be useful are for exceeding the maximum number of displays that your GPU normally supports, since indirect displays don't count towards that (because the GPU isn't directly driving them) and/or when you need to connect displays that your laptop doesn't have built-in outputs to drive.

Second, as to that USB to HDMI adapter you linked, that normally isn't a great way to connect a display, because the 'indirect display' technology that has to be used by USB adapters such as those in order to carry video over a regular USB connector introduces some drawbacks even when it works. A daisy chain only works when the entire chain uses DisplayPort, and the way it's set up is that the first display in the chain needs to have a DisplayPort output, which would be used to feed the DisplayPort input of the next display in the chain, and so on if you use more than two. First, you say you attempted daisy-chaining, but the S2719DGF doesn't offer a DisplayPort output to facilitate daisy-chaining, so I'm not sure what cabling arrangement you tried that you thought constituted a valid daisy chain.
