Realist9 :
Wouldn't it be smarter to pick up a 4k of similar size/specs like the Predator XB32 for $60 more?
Given you have the rig to run 4K?
My concern is relative adoption of 3440x1440 vs 4k. I *feel* like 3440 is not as widely supported as 4k, and with 4k, there's no fisheye (right?).
for ref: Currently running 3x32" surround on a 1080 (for ref concerning frame rate). 3440x1440 = 4.9M pix, 5760x1080 = 6.2M pix, and 4k = 8.3M pix.
I've tried 4K, and this is far superior. There is no 4K with similar specs. Two of the three most important things this monitor provides are missing on 4K; 100Hz, and 21:9. Before this monitor, I had a 144Hz monitor, and dropping to 100Hz was a sacrifice I was willing to make, but I'll never go back to 60Hz, even with G-Sync/FreeSync. And 21:9 is the real difference maker. The extra horizontal screen real estate is amazingly useful, and it's what provides greater immersion than ever before; probably immersion that can only be beaten with VR (not even with triples because I hated the bezels).
I don't see any adoption issues. Firstly, this format is becoming more and more popular all the time. Secondly, whether it's adopted by the masses or not, I'v had zero support issues to date. The most I've had to do is edit a config file (World of Tanks), but all other games have been completely straight forwards.
There's zero fish eye in any games. I'm not quite sure what you're getting at.... I mean, your in-game FOV isn't distorted by having a wider monitor; you just see more left and right, in a completely natural manner; there's no stretching to fill it.
I've tried triples and 4K, and I firmly believe that the three most important factors in a gaming monitor, which I'll never go without again are:
21:9
G-Sync/FreeSync
100+Hz
Resolution would only be 4th on my list, and I'd even take a 2560x1080 21:9 before I went to 4K, just so I could have the 3 must haves above.
