Plus Samsung's new one (basically 3 monitors or 2 ultrawides. It's a 49" display): 

There have been a lot over the past few years, now its mostly ultrawides and samsungs extra ultrawide monitors

I dno, I'd much rather have that one (Acer makes one as well) than the Samsung. The Samsung has pretty low resolution for its size. I wouldn't get a 27" 1080p monitor, I definitely wouldn't get one that's a whole lot wider. Pixelation galore.
Yeah, but a horrible resolution. It's too big for something 1080p.

If you want a cheap ultrawide solution, grab a pair of Dell monitors. They have ridiculously thin bezels.
There are also some niche monitors by some other companies (Porsche Design I think has a colab one) but they're generally more expensive.
IIRC it's similar to having 2 27" monitors stitched together. Definitely not the same as 2 ultrawides.
You for got the glorious 37.5"
The 49" is 32:9.

They're actually quite literally seamLESS. Less seams != no seams 

Dang it! Coolslammer beat me to it, but here's my version. lol!
