Okay, got it. DisplayPort 1.2 and HDMi 2.0 both support 3440x1440 at 100 Hz, so you have some options.
Something like this looks like it would work pretty well. It looks like only the mini Displayport version is DP 1.2 though.
Otherwise you could go for an HDMi 2.0 switch like this and then pair it with some adapters like this.
Yep, is more expensive up front but allows higher end monitors when you upgrade. Something like this looks sensible https://www.amazon.com/gp/aw/d/B00ZR18VPS/ref=mp_s_a_1_1?ie=UTF8&qid=1506559387&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=displayport+kvm+60hz&dpPl=1&dpID=31IWMo%2BrJIL&ref=plSrch

Purchased Dec 2017. Thought I had it a bit longer than that but I guess not!
According to rule 4. we're not supposed to give product recommendations. However, because I see a few pitfalls, I recommend this one. It has 4K @ 60 Hz support. You'll need to get two of these, one for each screen.
There are also KVMs that can switch two monitors at the same time like this one, but as you can see they're in a different price class ($500+).
Edit: also, use quality short DP cables. DP cables can't be long, and the switch is not a repeater, so the total cable length counts.
This was probably the best one I tried. It worked for 1440p@144Hz and also does USB switching. Little expensive, but everything cheaper seemed to only support old DP standards.

Honestly, I didn't even check. Didn't think anyone still had 1.1 one stuff on the market. That is surprising...
No those would not work then. Good catch.
After looking around more it seems most are 1.1... That seems strange.
I did find this one that will do DP1.2 but you will have to get mini-DP/DP cables for it: http://www.amazon.com/StarTech-com-2-Port-DisplayPort-Switch-SV231MDPU2/dp/B00ZR18VPS
