Hey, so I don't normally post here, I suppose I'll get right down to it. I apologize in advance for the relatively disorganized post.
I've got 3 monitors. 2 ASUS 23" that run 1920x1080, and 1 LG 29" Ultrawide that runs at 2560 x 1080. my GPU is a Sapphire Vapor-X R9-280x (1 DVI-D, 1 DVI-I, 1 HDMI, 1 Display Port).
I'd like to run all 3 monitors with the LG ultrawide in the middle as the primary, and the 2 23" ASUS monitors on the left & right of it. As it stands, my GPU clearly detects all 3 monitors are plugged in, but I can only get it to display to two. Whenever I try to go into resolution settings to tell it to actually extend the desktop to the third display, I get an error saying "Unable to save display settings."
Currently the monitors are hooked up cable-wise as the following
(going from PC -> monitor)
LG // HDMI -> HDMI
ASUS // DVI-D -> HDMI (cheap INSIGNIA brand HDMI to DVI-D Cable)
ASUS // (this one's a bit wonky but is still detected) DVI-I to VGA Adapter plugged into PC (just one of those little blocks, not actually a cable), then VGA cable plugged into that and the monitor.
From what I'm reading, I need an "Active Display Port Adapter", but I'm not sure what SPECIFICALLY I should get to plug into which monitor. Like, do I get an Active Display Port to HDMI adapter, and plug that into the LG as the primary, and then use DVI/HDMI for the other two? or what? Any recommendations on what to use specifically?
As far as the ports go in the back of each monitor. The 2 ASUS monitors both have 2x HDMI & 1 VGA. The LG (model 29um65) has 2x HDMI, 1 DVI-D, and 1 Display Port.
From what I understand, I just need an Active Display Port adapter to plug in one of the monitors. I'm just not sure what exactly that means I need to buy. Do I buy something that is Display port Male that plugs into the computer, and then has an HDMI/DVI/whatever female on the other side or something? Is it a full cable that is male displayport into computer with male dvi/hdmi/whatever to plug directly into the monitors?
I know that's a long post, and a little disorganized, but I GREATLY appreciate anyone who has the patience to help me out real quick. I'm not technologically inept or "computer illiterate", I'm just new to running more than 2 monitors, and I've never F'd around with display port or ultra-wide/high resolution. Built the whole rig myself, have been building rigs for the last 4-5 years now, and I work in entry-level IT. Feel free to throw tech speak at me, if I don't know it, I'll google it.
If it matters, here's full specs of my computer via Speccy.
TL|DR? -> want to run 3 monitors. have r9 280x. have 29" ultrawide + 2x 23" regular. from what i'm reading says I need active display port adapter, I'm just not sure what exactly I need to get. Specs for whole PC are below, or specifics for ports available etc are listed above. Please & TY

I'll suggest the following1). Upgrade your vga connection to hdmi (even if it needs a dvi adapter) as this will remove the analogue wildcard.
2). Use a displayport cable with your LG superwide screen, there's no need for active adapters then. You may not need to do this if the first works.
For comparison, I have a system with an i7-4770K and a R9-290. This has driven triple screens at 1920x 1080 all on hdmi/dvi cabling without the need for any displayport adapters active or otherwise. It's currently driving an ASUS 4k screen flanked by a pair of BenQ 24" 1920 x 1080 screens. The 4k screen is driven through displayport as this is the only interface that supports 4k at 60Hz. The pair of BenQ screens are connected by hdmi.
Yeah so. I tried all HDMI, including using a DP-> HDMI adapter. I've read tons about multi-resolution and my monitor and graphics card both support separate resolutions. Eye-finity has no problem with that. also, all 3 are 1080. I've also seen evidence of this as I watched someone have it hooked up with DP with 3 different monitors that all ran at dif resolutions.
I either need a good Display Port cable, or a good Displayport to HDMI ACTIVE adapter. I just can't seem to find one.
