Three monitors, which one to choose?

[kyube]

I have stable 600-700fps, but just blindly buying monitor of a refresh rate is not good, what about response times, input lag, motion clarity, ghosting, smearing etc? for example xg2431 is “certified” monitor here, but in reality it is very very bad, that motion clarity is good only on low hz not max, and if using strobing, which increases very noticeable input lag and besides all this you cant see anything because that strobing dims monitor completely. there are many monitors and I do not know how to pick one

The formula for total display latency (what you refer to as “input lag”) would look something like this:
Display scan-out (refresh rate) + processing latency + G2G response time
G2G response times are not a singular value, they're a multitude of values in the 0–255 range, meaning this formula above would only apply to 1 transition

What you're referring to as “ghosting, smearing etc.” are just vague terms to describe the behavior of G2G response times.
Usually used for IPS displays (“smearing”), VA displays (“black smear”) and some worse TN's

Motion clarity is also a vague term, which doesn't mean anything when read without an adjective (“great, worse”)

The XG2431 does not add significant processing latency from enabling PureXP, as per RTINGS & TFTCentral.

Your issue lies within the actual brightness, which can be a bit limiting on it.
Zowie are the only other option if one wants a higher brightness LCD backlight strobing experience.

As for your dilemma which display to choose, I've given you a easy solution.
Opt for the highest refresh rate possible within your budget.
Use a site such as geizhals to limit the price point, find the highest refresh rate and purchase that display
360hz IPS displays, in terms of G2G response times, perform more or less identical (within 1–5% difference) in terms of overall visual clarity, whether in motion or static.
Display such as AW2523HF, XG259QN(S) are more or less identical, the difference lies within electronic internals & thermal performance.

Maybe this infographic might give you an understanding to this topic:


This image explains how visual clarity of objects in motion on a display scale when refresh rate (& content frame rate) is increased.
LCD backlight strobing solutions (PureXP, DyAc, ULMB, old CRT's) skip this scaling entirely, allowing you to get the same image as <1ms on much lower FPS & refresh rate.
It's also (very likely) why you read people online with the notion of “60FPS is enough”, because CRT's were impulse-based & were hiding the motion blur from the low refresh rate.

Hope this helps.
