A bit about overdrive.
25f out of the box has overdrive 2.
in test https://www.testufo.com/photo#photo=eif ... 0&height=0
the selected area turns green https://imgur.com/91tlx7t
overdrive 3 only enhances green
reducing contrast from 80 to ~ 70 helps. but colors and brightness are greatly reduced.
The green color on the tower and the remainder of the cursor https://imgur.com/xRasTyY are the same thing and are eliminated by lowering the contrast.
25 does not have these problems with stock settings. The test https://www.testufo.com/ghosting#backgr ... &pursuit=1 is very good. Looks like pg258q with 30 contrast. But with normal colors and brightness.

at 25 it is quite possible to use overdrive 3 and 4. but you can not touch the stock values of rgb.
If you want to reduce the blue color, you will have to use only overdrive 2, otherwise the story with the green color 25f will repeat.

viewing angles. like many, I'm used to viewing angles of tn panels. light bottom, dark top.
But 25 could surprise me, green top, red bottom.
xg258q is not acceptable for the browser and 25 joins it.

This method is inaccurate.

I don’t know what conclusions you made.
I do not pretend to be accurate.
There are no words in my posts: Versus, input lag, etc. ..
I tried to evaluate the work of overdrive, from 1000+ photos I chose the most suitable.
What I saw with my own eyes I saw in the photo.

We appreciate users bringing feedback to Blur Busters!

That said, I believe Q83Ia7ta is referring to the accuracy of the two-monitor photographed latency test -- side-by-side photo based latency tests have their limitations but are useful when there's multiple frames of latency. The more accurate qualification is that it's not entirely inaccurate, just has "accuracy limitations" but those, too, can be understood, calculated, and controlled with a bit of knowledge. (We consider that readers do a lot of work trying out tests).

It's accurate to an error margin of approximately (camera shutter time + refresh cycle time), though there can be additional variables. So a 1/240sec shutter and a 240Hz monitor, will add about a 2/240sec error margin band to your latency result comparision. That can be good enough for some user testing if you don't have other requipment. It just often not able to go millisecond-accurate. To minimize sensor scan interactions (camera sensor scan direction versus monitor scan direction), put two monitors horizontally side by side, and always photograph landscape. Also, GPU mirroring can also add an indeterminate amount of inaccuracy, so to compensate for that unknown, swap cables (at the GPU output) and average the results. One just merely have to understand the limitations & error margins of the two-monitor photographing tests. Though, it's easier to get much closer to millisecond accurate with a 1000fps high speed camera (even if low-resolution one).

A fair and more accurate qualification is "For the latency-testing portion of the tests, the side by side two-monitor photograph is less accurate than other tests such as high-speed camera. However, it can be used when no other equipment is available, and if the error margins are acceptable for your needs".

GPU mirroring is inaccurate method to compare input lag. The work of overdrive can be seen at testufo.com at ghosting test for example.

I repeat once again. I did not write in the title of the topic and in the post "input delay." I even posted this post in the "THE CAFETERIA Offtopic Lounge" section. Why are you so persistently telling me that the input delay test is inaccurate? I did not do this test. I don’t have the right equipment for such a test.

Hey I just ordered the Omen X 25 G-Sync Version.
What settings do you recommend for lowest Input Lag and the least Motion Blur/Ghosting and still having good colors.

Photos were taken from 1/1000 to 1/3200.
If the software does not fool me.

Do you propose to limit yourself exclusively to testufo.com at ghosting test?
I'm not so conservative. and I prefer to customize each color (rgb) separately using a completely different test.
But you are right, the traditions of the forum should be respected.

Aren't you interested in checking this yourself? or you replace monitors so quickly that there is no time to study them)). I recommend returning it, vertical lines (inversion) spoil everything.
