Please help me decide
Usage will be mainly for MMO games + watching movies.
Thanks in advance.
Yes, many games now natively support 21:9. Here's the listing FYI:

Any bros seen & compared the 2 monitors before?
My recent monitor journey has been 2711 -> 3014 -> 3415w -> QX2710 -> Philips 40' 4K.
My recommendation is that instead of going 21:9, go instead to 4K assuming your GPU can support it at a decent setting. When using 3415W, there are 2 issues with widescreen 3440 by 1440;
Gaming
1. Native support. I'm still baffled that such a popular game like Fifa doesnt have support for widescreen. Not even widescreen.org have a solution... then Fifa16 is coming, so there may be hope there. The good news is most if not all recent games all support widescreen so there is no need to worry at all.
2. Native resolution support but lousy scaling.. some games scale very badly.. one i can think of is Warcraft an old game.. it has the resolution support but everything is stretched so bad i switched to 2560/1440 when playing. There is another game but suddenly forgot the title as i dun play much.
Movies wise on the other hand is excellent. i tried Hobbit and it was a great experience with the multiple huge landscape scenes. If your source has the right resolution all is fine.
Productivity wise
both 21:9 and 4k are equally good.. use application to allow splitting of your desktop into multiple section to fully make use of the desk space.
Get a 40 inch 4k tv, nuff said
most 40 inch tv are no 4:4:4 chroma with higher than 24ms input lag rendering most games not enjoyable.
dont anyhow recommend.

I will go for VA panel from Samsung instead. No ips glow, and also a much more premium finishing. Pretty solid if you were to ask me.
VA black contrast is nice.

This.. i have to agree that VA panel is really good with the Blacks.... can see the difference compared with IPS/PLS panel.
Btw this ultrawide 21.9 screen is bad for rts game like dota2 /LOL because too wide until ur char look so fat , the rest like fps /racing are good .
