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
