Yes, I will.

k2viper, can you post a screenshot about your options sreen for Latencymon?
...and also, do you guys have the paging file disabled? (I do...)

No I didn't, here you can find the lowest digit with LG 240 hz with 1 ms MBR activated and VT 1304
Stats are the same both for samsung 144 hz and LG but the Samsung sits like....almoust always from 5 to 10 ms.
Both seems to run between 3 and 30 ms most of the time the LG around 20, but the samsung around 5/10 ms.
For this reason I don't know if it's true the current value or the average values in STATS, as result the monitor seems pretty fast.
(average STATS are the same for the two monitors, but not the "current measure" as I explained before. )

I have black tuner: 75
luminance 100
contrast: 63
sharpness: 50
response time: faster
MBR activated.

The only bad thing is the lowest part of the screen where crosstalk is not great, center better, but not perfect something like the other Asus or acer panel I guess . I'm really curious also to see the Benq XL2546 or the Dell freesync 240 hz @a solid lad tested.

p.s.
Dunno why VT1304 made my contrast higher and blacks deeper, I like this thing.

Never touched the LatencyMon options, its defaults I believe.
Pagefile is enabled @ mine, but size is locked 8 gb afair.

If It can help, in the Human benchmark I have 170/180 average ms with LG monitor when I'm focused, a result very similar to my samsung.
But, is hard to catch a true input lag value without the right instruments,
Did you find other interesting things in my previous reply?

Nice readings, what gpu and driver ver.?
I'm not sure too, if we should consider average from STATS page correct or not.

Human reaction benchmark have much human-related variance )
I scored 150ms even with old VG278H and LG is definitely faster so I believe after some training I should score around 140-150.

It seems similar to the LG monitor, but maybe a "street view" test could help more.
One thing I don't understand is that VT1304 doesn't seems to improve the MBR, maybe just a bit the Blacks.
I followed your tutorial with ToastyX, after restarting the PC the digital brightnees was resetted in the Nvida panel so I guess it worked.
Do you find a real better MBR with the VT 1304?

I use gtx 1080 ti, driver version 391,09 I guess.
Yeah that is important to understand a relationship between input lag and DPC.
(at this point considering similar the quality of MBR from LG and Benq , maybe the one that has better values, could be better)

p.s.
150 ms is really good with the asus monitor, what is your score in the Human benchmark with the LG instead?
I'm a little tired, but I'm experiencing about 170/180 ms with this monitor, similar to the samsung. (not the lowest, but the average)

You two are really fast... I could only manage around 190 if I tried really hard, lol.
Are u using the same test as me? (https://faculty.washington.edu/chudler/ ... green.html)

btw, I've realised as well, that drivers play a huge part in dpc latency... I was about to install the latest drivers after uninstalling the previous ones with DDU (thought I'd give fresh gpu drivers a try) AND BOOM 4-6 microseconds of latency in dpc latency checker...
so guess I'll have to reinstall drivers until I find one with low dpc overhead...
