Difference between 1ms and 4ms monitor lag (fighting games)

[Sugar Hill Contract]

About to buy either the Asus PG278Q with 1ms of lag or the IPS Asus PG279Q with 4ms of lag, wanted to know if the difference is noticable for fighting games. Thanks in advance. Happy holidays.

Is that grey to grey timing?

Nah input lag.

EDIT: Looking like grey to grey

Asus PG278Q is a TN panel based LED backlit LCD display.

Asus PG279Q is an IPS panel.

IPS would be richer and brighter, plus greater viewing angles. The difference between 1ms and 4ms is a good trade off, which I would personally take. It's very little difference performance wise, but the monitor image quality will be a lot different.

Screen Uniformity - Black Field (lower is better):
Asus PG278Q = 16.20
Asus PG279Q = 17.58
(1.38ms difference)

Screen Uniformity - White Field (lower is better):
Asus PG278Q = 13.49
Asus PG279Q = 10.22
(-3.27ms difference)

Screen Uniformity - Color (lower is better):
Asus PG278Q = 2.47
Asus PG279Q = 3.83
(1.36ms difference)

Pixel Response And Input Lag (full black to white):
Asus PG278Q = 6
Asus PG279Q = 8 (OD Normal)
Asus PG279Q = 7 (OD Extreme)
(1-2ms difference)

Absolute Input Lag (full black to white):
Asus PG278Q = 23
Asus PG279Q = 25 (OD Normal)
Asus PG279Q = 24 (OD Extreme)
(1-2ms difference)

So real-world performance testing shows there's 1-2ms difference between the two (overclocking normal or extreme with 165Hz G-SYNC). The human eye won't really notice that at all.

The difference between TN and IPS is huge, hard to see in images if on a TN, however (TN on left | IPS on right):

I'd recommend focusing on the HZ instead of MS timing of a monitor -- that's more of a gimmicky thing sellers have started to do to make it seem more appealing and technical to the consumer.

Under 10ms is generally GTG timing; you will not get those low timings when you consider the actual GPU to Display timing.

For fighting games no you won't tell the difference and the IPS will look better in those games. Many fighting games are console ports and have a 60fps limit anyway. Many 1ms monitors have high refresh rates rates like the one you are looking at and you will not benefit from that in many fighting games.

So, based solely off of the fighting game specification I would get the IPS@4ms.

No human can see that difference. It's all thinking you can. If there is lag it's something else going on. No human is that fast fighting or shooting. The most lag is PING rate from the client to the server.

And for FPS same answers?

Asus PG278Q = 144Hz refresh rate (144 FPS)
Asus PG279Q = 165Hz refresh rate (165 FPS)
(21 FPS difference)

120Hz was designed for V-SYNC (most of these monitors cap back automatically when V-SYNC enabled - divisible by 30, 60, or 120)
144Hz was designed for 3D and Movies (dividible by 72 and 24)
165Hz was designed for G-SYNC (bit of marketing as more is better, g-sync limit from 30Hz to this max)

Both use G-SYNC. The difference between 144Hz and 165Hz is minor, but still there if your graphics card can max it out. A slight increase in head room.

G-SYNC should use DisplayPort 1.3 cable or better, must be Nvidia graphics card in order to use, and gets enabled on the monitor and under the Nvidia Control Panel. It then requires at least 30 FPS. Will sync the monitor's refresh rate with whatever the maximum output of the graphics card can handle.

NVIDIA G-SYNC is groundbreaking display technology that delivers the smoothest and fastest gaming experience ever. G-SYNC’s revolutionary performance is achieved by synchronizing display refresh...

GTG is only part of overall latency. Look at the monitor as a whole. Very few reviews or overviews actually look at latency, other than GTG. There are a few that actually test overall latency, and this is what you would want to look at if you truly wanted to know about latency.

Also note that there are more factors to the overall latency than just the monitor.

GTG is only Grey-to-Grey portion of the RGB Pallete
And that GTG timing is Pixel rate related; most screens average approx 10-16 ms Signal from GPU to Display

@ 60hz, 1ms or 2ms you get positive white ghosting, 5ms or more you get negative grey ghosting, 3ms or 4ms should be optimal and run without ghosting.

Now there's also a difference between 60hz and 144hz ghosting, if both have 1ms timing the 60hz will have a much larger (more than double the width) ghost than a 144hz monitor.

If you're looking at 144hz 2ms should be optimal.

I don't know if there is anyone who could into to. I was thinking on getting a portable monitor for my steam deck. A 1080p, IPS, 144hz monitor by "Arzopa". I did ask about the respond time and they said it's between 13-16 ms. Would it work fine for fighting games like SF6, T8 and GGS?
Thank you for taking the time.

hmm 144 should have a 7ms response time at least the screen. in driving sims where the steering wheel is shown it makes some. with 60hz the wheel on the screens is behind a half of rotation when moving fast. with 120Hz its moving same as the wheel on the table.
