Sadly It won't do 3440 × 1440... Its 5120 × 1440 and the Next 1 lower is 3840 × 1080 and that's the same as 2 1080p monitors side by side

so for Me its just Not worth it.... I also Really Like the Extra Screen Space top to Bottom and with the New Monitor it felt like i was Missing something.
I'm Gonna Dump it and Take it Back!!! I can't get over how Narrow the screen is... I like the Full Size Screen... I couldn't even make it through the Night with it its packed up Ready to Go Back to Micro center... It cost $1,500. and I'm Not seeing Huge Noteworthy Improvement over My Regular 4k tv because when playing in 4k you don't get Much more than 65 to 80FPS anyway so I rather save the Cash and use Vsync and Lock FPS to 60 because it looks almost just as smooth....
I'm gonna wait it out keep what i have for Now but My Next move is buy another 55in curved TV that supports Vsync... they already make Samsung & LG 55in TV's with Vsync and refresh rates are ~6ms.
My final thoughts are I'm Spoiled on Full Screen 4k Gaming... IMO for $1,500 that the WOW factor should have been instantly there!!! My Test Game was ACC because its the Most Demanding ... Ofcourse RRE and AC are going to flow silky Smooth with 100+ FPS in 4k they are Less demanding, No animated Sky, Sun Movement and have static Shadows... but truth is they All play Silky Smooth on My Regular 4k TV just a 60FPS... I Honestly don't see a big Enough difference to justify the upgrade.
Edit: Last week of My 3 week Vacation So I had a Free Day to Tear My Set up Down and See if I Really want to do a Large Monitor or even triples.
