Looking for monitor arm for my lg 34 inch monitor

[oo2k15]

So the stand that my monitor comes with is flimsy. There's no height adjustment or whatsoever. I'm looking for a monitor arm that can support my lg 34 inch monitor. The monitor weight with the stand is 15lbs and it comes with power adapter. I have couple monitor stand in mind like Ergotech Freedom arm, Ergotron lx desk mount and Amazon basics single monitor arm. I was thinking of buying monitor stand instead but I don't want to add clutter to my desk. Also I have my desk all the way up against the wall, so i'm not sure if I have enough room for full functionality of swivel, but I can accomadate that by moving closer to me so is not really a problem I guess. So can anyone suggest me a good monitor arm for my lg 34 inch monitor? Will be much appreciated.
