Noob Question on Monitor Desk Mounts

I just joined the 1440p club and have purchased an xstar monitor. As a result, I plan to also purchase a desk mount to hold my new monitor and my old(hp 2509b). Both monitors are 27'' and have rather large bezels. My question is for a desk mount is it necessary to have the same monitors on one mount or is it possible to have different ones? I'm just worried that a mount wont be able to fit both monitors side-by-side due to the large bezels.

Any clarification is appreciated. 

 

Thanks!

 

Just grab some 2x2 wood, screws, bolts and a one way wheel to build a mount. much more cost efficient.
