Motorola announces the Edge 50 Pro phone with a 6.7-inch screen and Snapdragon 7 Gen 3 processor – Tablets and Phones – News

From what I understand from the first Edge displays, this problem was solved simply by defining some kind of dead zones, so that touches on the sides are ignored and still work no matter how you hold them. At least, that was actually 10 years or so ago.

Imo, the fact that peripheral displays don't have that success has to do with very practical things. It's expensive, and even more expensive to repair (especially since something like this is also more vulnerable, and falling into its corner is worse), but the added value is minimal. It doesn't really make the usable screen larger, you don't want to play video and such on that edge, because then you'll lose an edge in your field of view. You also have to hold it, so if the content is too close to the edge, there's a good chance your hands are partially on top of it. Having a frame isn't really a bad thing.

So, it's especially nice to display case things, so you can read your phone on its side if there's a flip cover around it.
But given the small size of this edge, I don't think that's the case here. However, it's more of a gimmick than really useful.

Therefore, the disadvantages do not outweigh the disadvantages. Now, years later, these monitors may have become cheaper (repair is still a possibility) but the hype surrounding them has already evaporated. The question remains more “Why?” What do you really gain from it? It's purely aesthetic, if you like it, that's fine. But imo, there's not much more to it than that.

All imo of course, if I missed anything positive, please let me know.
