There's also a handy tool in this thread on the forums.

In addition to what @Spotty said, for pretty much any type of digital connection you can see if any resolution and refresh rate will work by figuring out the data rate required and comparing it to that standard. 

Per example- Lg's new 32:9 5120 x 1440 60Hz monitor (49WL95C-W) isn't on the chart. 

 

You can see by that chart that 5120x2880 at 60Hz is 22.18 Gb/s. Since this monitor is exactly half the overall height and half the total pixel count, it requires about (not exact) 11.09Gb/s to make it work. This puts it as a little less than the 4k60 data rate, which lines up as the total pixel count of 4k is 8,294,400 and the LG monitor is 7,372,800. This means whatever weird adapter setup you want to run it off of should work (in theory) if it can output 4k60. 

 

Actually the math is probably easier to just find the same frame rate and factor in the pixel count difference, but whatever either way 

muh specs 

Gaming and HTPC (reparations)- ASUS 1080, MSI X99A SLI Plus, 5820k- 4.5GHz @ 1.25v, asetek based 360mm AIO, RM 1000x, 16GB memory, 750D with front USB 2.0 replaced with 3.0  ports, 2 250GB 850 EVOs in Raid 0 (why not, only has games on it), some hard drives

Screens- Acer preditor XB241H (1080p, 144Hz Gsync), LG 1080p ultrawide, (all mounted) directly wired to TV in other room

Stuff- k70 with reds, steel series rival, g13, full desk covering mouse mat

All parts black

Workstation(desk)- 3770k, 970 reference, 16GB of some crucial memory, a motherboard of some kind I don't remember, Micomsoft SC-512N1-L/DVI, CM Storm Trooper (It's got a handle, can you handle that?), 240mm Asetek based AIO, Crucial M550 256GB (upgrade soon), some hard drives, disc drives, and hot swap bays

Screens- 3  ASUS VN248H-P IPS 1080p screens mounted on a stand, some old tv on the wall above it. 

Stuff- Epicgear defiant (solderless swappable switches), g600, moutned mic and other stuff. 

Laptop docking area- 2 1440p korean monitors mounted, one AHVA matte, one samsung PLS gloss (very annoying, yes). Trashy Razer blackwidow chroma...I mean like the J key doesn't click anymore. I got a model M i use on it to, but its time for a new keyboard. Some edgy Utechsmart mouse similar to g600. Hooked to laptop dock for both of my dell precision laptops. (not only docking area)

Shelf- i7-2600 non-k (has vt-d), 380t, some ASUS sandy itx board, intel quad nic. Currently hosts shared files, setting up as pfsense box in VM. Also acts as spare gaming PC with a 580 or whatever someone brings. Hooked into laptop dock area via usb switch
