Two identical 144hz monitors, different results

[TheOtherUs]

I have two IIYAMA GB2788HS 144hz Monitors for both my pc's which have the same specs, but one performs well and the other feels a lot worse.
Any ideas on what could cause this?
I thought it might have to do with Nvidia settings but i've made both setups identical. Help is very appreciated !

Are the screens roughly the same age and with the same usage?? LCD screen deteriorate over time, losing brightness amongst other things; if one is older, or had more use, you might be able to see the differences with the screens next to each other.

Well actually the new one is the one that performs worse...

First, I have to say the prerequisite that these are somewhat sketchy monitors and a crapshoot.

Second, what do you mean by one feels off? That's very for a reader to quantify in terms of a monitor. Like one is running 144hz and one is 20hz?

Different batches can come out with slightly different results, especially if they have substituted components along the way (happens more than you would like to know); however, are you sure it isnt just how the new screen has been calibrated?

Calibration on most cheaper screens IS a crapshoot, you could buy 3 with sequential serial numbers and find one set far too dark, one set far too bright, and the third wildly off on all settings.

Define "feels a lot worse".

I had 2 very nice HP IPS panels, bought as a set, almost sequential serial numbers.
No amount of messing with them, including a hardware colorimeter...would make them "equal".
They were always just a little bit different.

Yes, it seems that when playing games in fullscreen it feels like the monitor is playing games at under 100hz with noticable microstuttering
