I originally came from two matching 25" 1080 monitors and originally only replaced one with the 34", but the physical size difference as well as PPI difference meant it didn't work for me. I'm now running a 34" 3440 x 1440 and a 27" 2560 x 1440 These work out to be almost exactly the same vertical height which means they are almost identical in PPI so moving things from one window to another doesn't get funky. Of course, this does mean I have two non-matching monitors, and the 27" is IPS where the 34" isn't so there is some difference, but it's not jarring with a little tweaking of the panels. I did consider a second 34" screen, but ultimately decided against it for a couple of reasons. #1 - It's bloody HUGE! Two of them really would have seen me physically turning my head from side to side to cover the 1.6M of screen I would have. While my desk is big enough to accommodate it, I just don't know that it would have been right. #2 - It would have meant having a left and right monitor which means gaming (or working) off to one side. With 2 x 25" units both were pretty much right in front with just under 1.2M total width. It didn't take too much to see both, I feel like two 34" really would mean 'off to one side'... as it is the 27" feels like it's free far off to one side. I actually feel like 2 x 34" monitors would work better one on top of the other, but not something I'm setup to try even with the current units. Now I did get into this for gaming and the extra side to side view. On reflection do I think it's worth it?? Yes and no. It's nice to have, but probably not as ground breaking as I thought it might be. Productivity wise though I feel like it's a win. All of that said, I think had I of just purchased a pair of higher resolution 27" units it would have been almost as much of a step up. Mind you I would still have the same downside of my USBC dock not being up to the task and still would need more graphics power than 1080 gaming requires. I looked at those sort of models where it is really the resolution of two monitors side by side... but one and without the bezel. But pricing it madness unless you're doing something that really benefits from not having that bezel (and have the power to drive it). For most people it's probably cheaper and easier to just buy THREE monitors! While I know there are tools, I'm a heavy user of the 'snap to edge function' of Windows and having physical monitors creates more edges to snap to.
