hi guys first time here,i didnt found normal guide for my monitor
im playing csgo compedtievly got ~300fps in 1280x960 resolution
any advices on lowest input lag?
blur reduction should be on?
ama od gain i use 3c in service menu is it good?
in strobe calibration utility in persistence clearer motion or brighter screen? in crosstalk area earlier strobe phase or later strobe phase?
black equalizer adds input lag?
my settings
picture mode: standart
colorfulness: 15
low blue light: 0
instant mode: on
brightness: 100
contrast: 60
sharpness: 10
gamma: 5
color temperature: normal
ama: high
and in invidia control panel should i use gpu or monitor scaling?

1280x960@240Hz is most probably not a supported resolution in this monitor, so GPU scaling is forced. If your monitor OSD shows 1920@1080, then you know GPU scaling is forced. GPU scaling is preferable anyway because it does not add input lag, while display scaling is known to have input lag in many monitors. However, display scaling is higher quality, while GPU scaling is blurry. You might want to try 1440x1080 instead. It's a 4:3 resolution, just like 1280x960, but it matches the vertical resolution of the monitor and thus is not scaled (unless you use stretched, but even then, it's only scaled horizontally, and not vertically.) To get 1440x1080, you can use the CRU tool, or the nvidia control panel.

The strobe calibration settings are tweaks for motion blur reduction. If you have motion blur reduction disabled, they have no effect.

For lowest input lag, you should keep motion blur reduction off. However, if motion blur reduction actually works at 240Hz, then the input lag penalty should be very small. On the other hand, at 240Hz, you probably don't need motion blur reduction, especially for a game like CSGO.

Black equalizer should have no effect whatsoever on input lag, since it should only be modifying the gamma curve. I don't think it does any actual frame processing. But nobody tested. It's safe to assume however that it doesn't add input lag.

The overdrive gain should not affect input lag at all. It only affects pixel response. I would leave it at its default setting for best motion quality (setting it too high or too low usually results in ghosting.)

"Instant mode" should be enabled.

I don't know what "AMA" does.

The rest of the settings (colors, gamma, etc) have no effect on input lag.
