Minidisplayport supporting desired Resolution?

Hello everyone, I have an 21:9 Curved UltraWide Monitor (34")(WQHD) that has the resolution 3440 x 1440 and want to connect this to my Mac Pro (Mid 2012) through an Belkin 4K Mini DisplayPort to HDMI Adapter. I want to know since this is a 4k adapter will it still support the WQHD resolution after I connect it and also carry audio over as well not just a video signal. (Note: My current graphics card is an Radeon HD5770 1 GB so I know that supports up to 2560 x 1600 and I will be upgrading my card to support a higher resolution in the nearby future). If there is another adapter that will support my needs please refer them but for now I am hoping this Belkin 4k Mini DisplayPort will suffice.

Monitor Specs:

Screen Size Class (diagonal) (Inputs/Outputs) : HDMI x 2 (Power): Type: Adapter

it would appear that the adapter does support the resolution in question, but there are other adapters that do-kanex, moshi to name two. not all 4k displayport to HDMI adapters support audio-pass through but this one does. You should be good to go

on a side note: 21:9 34" " curved UltraWide Monitor ? Nice, Very Nice. Dude I am very awestruck. Must have cost you lots of ducats. Now, all you have to do is upgrade the video card. the R9 is possible, as is sapphiretech's 7950. you could even go with a flashed PC card, which ought to work. check out macvidcards.com (don't know about 'em personally, haven't used 'em, don't work there--only bit of info I know right now). Upgrading it is super easy. too. All you might need is a small phillips screwdriver, oh and this little nugget. there's a bar on the logic board which might be moved back before you install the video card. the button to do this is on the fan shroud towards the back of the mac Pro. If you don't push that button and get that bar going back, you're going to have a heck of a hard time getting that video card installled, and of course, don't forget to plug in the power cables. Other than that, you're A-OK

Connect directly with Mini DisplayPort (computer-end) to DisplayPort (Display end).

HDMI works great for 1080p TV sets, and once you try to go higher, the path is littered with aggravation, non-solutions, and land mines.

To both you guys thanks so much! It feels good to be reassured I had a good idea about the cable and yeah the monitor was a tad costly but it really works wonders. I appreciate the help from both of you guys and thanks for the feedback of the graphics card I plan to upgrade pretty soon.

Are you getting 3440 x 1440 resolution? Did you ever upgrade your graphics card? If so, what'd you end up getting that worked?
