Will my ASUS ROG STRIX GeForce GTX 1080 Ti be able to run an ultrawide?

Hi, a bit of a noob question here, I'm afraid!

Somewhere at some point I seem to recall reading something indicating that for some reason my Asus ROG Strix 1080ti would not be able to literally run 3440x1440 @ 180hz of the 34" 34GP950G-B due to bandwidth issues alone? And it would be fine on a 2xxx or 3xxx series Nvidia card? But I'm now starting to worry that I've dreamt this entirely, as I can't find anything online at all now!

I'm not too worried about the frame rates because I play really quite old/basic games, but I'd hate to buy an LG 34GP950G-B and then only be able to run it at lower resolution, as opposed to native.

Is there any sense at all in what I'm saying above or? please someone put me out of my misery either way!

What connection will you use, display port?

Displayport 1.4 maxes out at 144hz at 3440x1440 with 10bit colour iirc.

Aaah! That might be it! damn! but what about with 8bit colour?

Update - After googling a bit, it seems like 3440x1440 @ 180hz @ 8bit might JUST about be OK! details below

You can check that for yourself with my

The answer seems to be: yes, DP 1.4 HBR3 can carry 3440/1440/180/8. It can’t do 10bits.

Max refresh rate at native resolution and 10 bit color depth would be 144Hz. Dropping to 8 bits will allow you to go to 180Hz as monitors like the PG35VQ can run up to 200Hz with DP 1.4

I run a 34" ultrawide with a 1080ti, along with an 8086k.

Works absolutely fine.

Thank you for the reply. Could I ask which monitor exactly please, and at which hz?
