Why have such a high Hz rating at 2K or 4K

[test_123]

I noticed the some monitors have over 100Hz rating despite being 2K or 4K resolution. What does it buy you? For example, the Acer Predator XB271HU has 144Hz rating at 2K. However, even the mighty Titan V can only do 106 FPS average on Shadow of War. On Ghost Recon Wild-lands, you're lucky to get 40FPS at 4K. My point is the only way to make use of the high Hz rating is to lower the graphics settings or SLI a pair of Titan V's. Wouldn't it make sense just to stop at say 70-80Hz? Does game play look smoother at 100Hz vs 60Hz? I'm not knocking it; I'm just trying to understand the advantages of a super high Hz rating.

I don't know where you got those info,
But the 1080Ti is able to deliever more than 144Hz in 2k and kinda stable 60FPS on 4k depending on the game... And the Titan V isn't a gaming card to begin with...

I'm not even aware of a 144Hz 4k monitor(that, indeed, doesn't make sense), i guess you're a bit off road there friend...

Ghost Recon isn't exactly the most optimized game as well... And no, it doesn't make sense since the more Hz the monitor has, the smoother it's image is. And have you heard about G-Sync or FreeSync? Fast Sync? Give them a read.

They look much smoother. The difference between a 60Hz and a 144Hz panel is huge.

The first time i moved to 120hz from a 60hz screen the difference was night and day, even with out any kind of adaptive sync everything was smoother, even non 3d stuff on the desktop feels more fluid, this was all at 1080p.
I've since upgraded to a 1440p 144hz monitor, now you start to hit diminishing returns when it comes to what you can see, i'm sure there are some people out there that can "see" the difference between 120hz and 144hz, but for me it was all about moving away from 1080p and using freesync.
If you're a casual gamer then you might not even benefit or even see the difference between 60hz and 144hz.
It's something you really need to experience to appreciate, the same goes for freesync/gsync.

On Shadows, the review graph says 1080Ti gets 54FPS at 4k and 91FPS at 2K.

Do you see any ghosting at these high rates?

4K isn't mainstream yet friend, absolutely no reason to try to compare it with 1080p or 1440p which are the common gaming standards and have been around for a good while.

Ghosting occurs on poor monitors, not really(just) a refresh rate thing

Acer X27 4K at 144Hz. It won't be released until later this year. Maybe it doesn't count yet.

That's on the highest settings, some of us prefer smoother gameplay over the highest graphic settings and depending on the screen size you may not even notice lowering the graphics down to high from ultra to get that higher FPS.

That's just it. At 4K, having a super high refresh rate is kind of wasted because the current generation of video cards can barely squeeze out 60FPS at 4K. That being said, the X27 would definitely be future proofed.

Agreed. I'm looking to replace my monitor and I'm thinking of going 2K. With a high-end GPU, I should be able to get high graphics settings and high frame rates. It's the sweet spot for me.

I'd go over with a 1440p 144Hz IPS panel w/ G-Sync + Your High-End GPU like a 1080 or 1080Ti. That's the best IMHO.

You read my mind. I was considering the ASUS ROG Swift PG279Q. I heard there were QA issues. Hoping they resolved them by now.

I have a related question that no one has addressed yet about Screen Tearing.

Assuming you don't have adaptive sync on a 120/144Hz, 2K/4K monitor is screen tearing still noticeable?
Should one always use V-sync at high refresh rates?

I would think that using a normal 4K 60Hz monitor where even the best GPU has problems keeping the frame rate pegged at 60FPS or better will have a screen tearing problem if V-sync is off.

I recently got a nice 1440p 75Hz Freesync HP OMEN monitor, but I have a Geforce card for now.
For me, 75Hz is WAY better than 60Hz than I thought it would be.
I guess a burger tastes like a steak to a starving person that's used to PBJ.
However I have to keep V-sync on because the screen tearing is worse than my old monitor at 60Hz.

At a higher FPS any screen tearing should be less noticeable, vsync should help with this at it caps the FPS to the monitors refresh rate although if the FPS dips drastically then it will be noticeable. What I usually do is keep my graphic settings to a point where my 1080 ti keeps the FPS fairly close to what I have the refresh rate at. For single player or less competitive games I usually keep it around 100hz with a higher setting and with my FPS such as BF4 I lower the settings to keep the FPS at 144. With Gsync or Freesync (adaptive) the screen tearing should be much less, especially if you experiencing FPS dips.

Wow! I had no idea a bump from 60Hz to 75Hz was noticeable. I always assumed the human eye was capped at 60FPS and anything higher wouldn't be noticed (unless you're Chuck Yeager who had super human eyes).

Waay back when we had crt monitors, the graphics card needed to refresh the monitor display.
If the refresh rate was 60hz, you noticed shimmering of the image.
That did not go away until the refresh rate was 85hz.
I imagine that 85 fps is what one should shoot for.

Graphics card outputs are variable between frames.
Unless the output rate is gated by the monitor via freesync or G.sync, you are prone to screen tearing.
If you use vsync, you will not get tearing, but you will get more input lag.
There is a nvidia option called adaptive sync.
It eliminates tearing and reduces most of the lag of vsync.
