This adapter does not work, it only boosts 30Hz at 3440x1440 at most, if at all. Tested on two different computers, both capable of 4k without problems (HP 840 G3 and dedicated computer with 1080 graphics card). When speaking to support they said they only tested 4k, 2560x1080 and 1920x1080. What a joke when an adapter company that claims to be able to do 4K at 60Hz doesn't test more than a few resolutions on their adapters.
