So I just got 2 LG 29" Ultra wide res at 2560x1080 and of course my mac mini 2012 running El Capitan GM still not support it! Really Apple? I run bootcamp with windows 10 pro and it works just fine.

Anybody know the solution to this? Thank in advance.

Check your monitor/cabling/GPU - maybe try hooking it up via displayport.

Some versions of HDMI don't officially support 2560x1080.

I'm running 2560x1080 on my Hackintosh (Haswell + GTX760) just fine - interestingly in Windows it works via HDMI, but with OS X requires Displayport. Maybe driver related, maybe Windows driver does something non-standard/dodgy with the HDMI out on that card to make it do 2560x1080. Displayport no hassle at all.

I run 2560x1080 on my retina MBP 13 just fine (HDMI)

TB -> DVI on my 15" doesn't work any higher than 1920x1080

All running Yosemite - with an ASUS MX299
 
Try SwitchResX

I did and it still the same.

Yes I did all that as well and still no go. However, of course when I boot into windows 10 over bootcamp hdmi and display port work fine. I am guessing Apple needs to get their drivers together so everything works out of the box.

Ps: I am using both HDMI and Mini Display port since I have both ultra wide monitor side by side.

Are you using a Mini-Display Port to Display Port cable? Or a MDP to HDMI? To get that res it has to be MDP to DP.

It will not work over HDMI. Why Apple set this limitation is kind of crazy.

Yeah I am using mini display port to hdmi, and hdmi to hdmi.
 
I bought one and returned it.

It wasn't intuitive enough for me and I didn't want to mess with all the display settings to get it to work.
