just wanted to get some time in, testing both
so, vg258qm and itek ggf 288 are similar, but both seem to be too slow for 280(288)hz at 1920/2400pps.
they both look ok at 960pps but for me thats deceiving of ingame use.
vg258qm has weird overdrive behavior, only really affecting the dark transition top row in the ufo test.
the lower ones look smeary even at 1080. didnt do a video because of that.
itek is better there on high overdrive but has weird extra ghosting, when having contrast or RGB values over a specific threshold. lowering them makes them disappear. here is 288hz 1440pps as best as i could:

thats why i would go for the itek over the asus, as weird as it seems
but mine has 2 dead pixels and the stand is atrocious giving NO adjustment+its kinda facing down lol.
so im still not sure wich one to keep. another itek, the omen, or even the vg259qm(im going to take another look at the xg249qm and send videos of the ODs and a picture of the service menu, maybe someone has a clue)
i really wanted those higher refresh TNs to work, because i like the ~300hz range for fluidity and nonstrobed motion blur.
thats why i actually want to see some ufo shots of the acer 390hz on 300hz OD normal and extreme on 1440/1920pps.
