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! :D

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! :o 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've run 3400x1440 at 144hz on an AOC CU34G2X using a 1080Ti without issue. That particular display you are looking at actually has a native refresh rate of 144Hz according to a review I read of it, the 180Hz figure is actually an overclock and to achieve that while using variable refresh rate ....you actually need to drop to 8 bit colour and 4:2:2 chroma subsampling or you can stay with 144Hz and run 10 bit and 4:4:4 ...given that I wouldn't actually bother with anything above 144Hz on it anyway, despite what it says on the box I would think of it as a 144Hz monitor in all honesty, if you do, then your 1080Ti will be fine with it. So you will not need to reduce the resolution, only the refresh rate from that 180hz OC figure if you want to keep the colours looking their best.

Also another way to look at this is it's a monitor to upgrade into :D
