Can't get 7680x1080 on 3 LG Ultrawide Monitors

[ajburr]

I've been struggling, trying to figure out how the hell to get this to work. I have a GTX 1070, with 3 LG 25UM57 Ultrawide monitors, and my glorious plan was to get the resolution up to 7680x1080. Unfortunately, no matter what I try, I can only get 5760x1080 at max.

I have 1 monitor in HDMI, 1 in DualDVI, and 1 in DisplayPort. And therein I believe lies the problem. Is it the DVI that's limiting the resolution? The Displayport? Do they ALL need to be DP?

I'm seriously confused as not one step of this plan has gone right. Any help would be greatly appreciated.

Since they're ultrawide, I'll assume all 3 are at 2560 x 1080 resolution.
Why would you want to get the 7680? There won't be a noticable difference in pixel density (or any at all, depending on bezel length and such)
If you insist, its a problem with the display ports. I suspect its the HDMI.

 

[ajburr]

Yes all 3 are 2560x1080.

Why ask "why"? Every time I or other people bring this up, someone asks "why"? Here's why: YOU SEE MORE. Immersion, in other words.

I believe you that the HDMI is the problem. That'll be my next thing to try and fix. An HDMI to DP adapter ought to do it.

no, it's still limited by HDMI. You can't use any adapters in this situation.
Don't 1070's have 3 displayport outputs anyways?
Nvidia control panel may let you set a custom resolution though, like you have to type it in.

 

[ajburr]

The monitors only have HDMI ports, and yes the 1070's have 3 DP outputs. Custom resolution would be nice, but that option is greyed out.

From the 1070 page:

2 - 7680x4320 at 60Hz RGB 8-bit with dual DisplayPort connectors or 7680x4320 at 60Hz YUV420 8-bit with one DisplayPort 1.3 connector.

You need to use the same type of connection for all 3. Either 3 DVI-D or 3 DisplayPort. I believe you should have 3 DisplayPort available, so try those.

Edit: May need DP-to-something else adapters on all 3.

 

[James Mason]

I think you actually need DP monitors because the card isn't sending only a 2560x1080 signal (or whatever) to each monitor, it sends a 7680x1080 signal to all 3 monitors, and the monitors only show the section their assigned to show. HDMI is capped out at 4k.

I don't think so. The surround system also allows you to compensate for monitor bezels. The GPU is generating 3 independent video signals mapped to the proper space along the 7680 pixel width.

 

[ajburr]

Well I ordered 2 more DP adapters, so I'll let you guys know tomorrow if it works

 

[ajburr]

Nope doesn't work. Apparently I'm trying something impossible.

 

[GamingEnthusiast420]

I'm still not getting at what you want to accomplish here.
You have 3 x 2560/1080 monitors.
If they are side by side, aren't they basically one huge 7680x1080 monitor?
You're only making up for the bezels, which will ever so slightly increase your pixel density. But it will either result in a blind-spot or a double spot at the edges.

 

[ajburr]

I don't know what you're even talking about. Pixel density and crap. The whole point of having an ultra-wide monitor is to see more. The point of have 3 of them is therefore to see 3 time as much. It's a simple concept. Yes, all together they would be one big 7680x1080 monitor, assuming that the GPU would support it.
It's just a matter of having the right connections apparently. Got it now?

Anyway, I think the DP adapters I tried don't support 2560x1080. I managed to get two monitors (one DVI, one HDMI) to cooperate and I have a DP adapter coming that should support the resolution of the monitor.

Whatever happens, I won't be back, so don't bother posting.

 

[ajburr]

I debated as to whether or not I should bother posting this, but I did successfully link the 3 monitors together, one through DVI, one HDMI, and one DisplayPort. The DVI and DP are connected with adapters. In other words, all my monitors only have HDMI ports, but I connect those two with adapters.

The tricky part was the DP. I tried it with smaller, cheaper adapters and it didn't work. What I missed was reading the details of the adapters. I had to make sure it could handle 2560x1080. It actually handles much higher resolutions.

So it was just a matter of going into nVidia Control Panel and changing the resolution of each screen to 2560x1080, then going to Configure Surround and selecting 7680x1080.

Thus, IT CAN BE DONE. And man, it's beautiful.

Please make a video of it

Would you mind sharing what adapter you ended up using. I believe I am running into the same issue (trying to use two LG 25UM58-P 25" and one displays at 1920x1080 or something) TIA!
