Multiple Monitors from 1 Displayport

I picked up 2 2560x1440 144hz monitors recently but I can't get both of them to run at native resolution and 144hz off of 1 displayport output.  Is there a specific type of splitter or cable that you need to use?  Is there even enough bandwidth to do this?  Thanks in advance.

What gpu do you have? (you need displayport 1.2 or 1.3 or 1.4)

Main speaker setup is now;

 

Mini DSP SHD Studio -> 2x Mola Mola Tambaqui DAC's (fed by AES/EBU, one feeds the left sub and main, the other feeds the right side) -> 2x Neumann KH420 + 2x Neumann KH870

 

(Having a totally seperate DAC for each channel is game changing for sound quality)

I have a gtx 1080 but I am going to get a 2080 ti soon so if it won't work on this will it work on that?

The gtx 1080 is certified for DP 1.2 but ready for 1.3 and 1.4, you should check the cables you are using support 1.2 and up. you need one cable going to each monitor, so two DP cables.

I checked and my cables don’t support above 1.2 so I’ll order some on amazon and let you know if the problem continues.  Thanks for your help.

Also before you do that check in nvidia control panel that your displays are set to 144hz, under "change resolution"

Even in custom? (click customize then create custom resolution)

Okay, it lets me display 21:9 on my 16:9 display so should work with getting the correct res displayed on your monitors lol

So when I set my custom to 2560x1440 and/or 144hz it tells me the custom resolution has been set to that but then when i look at my custom resolutions it says 1920x1080 at 60hz.  The custom resolution works for my other monitors so I have no idea what's going on.

Sounds dumb but are your monitors on the right settings?

You will also be limited by the capabilities of the DP hub. There are no hubs that support more than HBR2 (DP 1.2) bandwidth that I'm aware of.

Oh damn i just noticed the OP is using a hub.. you need a display port cable going to each monitor not into a hub.. you should have the cables so go straight from the GPU to the monitors.. get the hub out of there

Oh I didn't see that reply.  I only have 3 displayports on my gpu and I was gonna run 4 monitors off of it.  Is there anyway to do that?  Also do any rtx 2080ti cards come with support for 4 2560x1440 monitors?

you have a 1080 right? The 1080 can run 4 monitors at 2560x1550 at 144hz aslong as the hdmi cable is 1.3

Omg I'm stupid I tried to use HDMI but I didn't realize I was using an older cable.  I'll order one and get back to you.
