hi! i just made an account to post in this thread and it was very helpful to me and i thought i would helpa bit too.
i just bought an acer predator XB241H bmipr, AKA acer predator XB1. i want to share my experiences
i got it for around 355$ from the microsoft store new, shipped to my house.
out of the box, everything is fine, no dead pixels, no significantly
noticeable regions of different brightness, no bleed that i can notice. now this is not the absolute best image quality monitor, it is not an ips so i dont expect perfect
picture, but i want it to be damn good and most importantly smooth.
so out of the box, no dead pixels, no lower right hand bleed or anything. btw i run it at 144hz, no overclock.
the gsync set up was very easy with my GTX 1o7o, and it worked flawlessly after the first try.
the 144hz is a big step up from my 6ohz TN monitor which i used to have. the first thing i noticed is that, while it doesnt really look different, when i moved the mouse around it really, really feels different. after a while i got used to it but returning to any 6o hz monitor makes me feel like bleh!
so now for the DOWNSIDES. the way the menu stuff works and buttons work on the monitor is TERRIBLE! but this is not a big deal. i eventually got used to it.
the real issue is the colors are VERY VERY UGLY! I have other TN monitors and this XB1 out of the box has colors SO MUCH UGLIER that i was seriously considering returning it.
but looking in here and googling i found a solution that worked for me. i changed the ICC profile and it looks much much better to a degree that i am happy with it. the color is NOT as nice as an ips monitor, but after this adjustment it is AS GOOD as my other TN monitor which i was very happy with already.
here is where i got the ICC profile http://www.tftcentral.co.uk/articles/icc_profiles.htm#the_database
just find the ICC profile from the list, under XB241H
then enable that ICC profile using these instructions
you are supposed to do this while the monitor is at factory settings, which is what i did i am pretty sure. you can fiddle with the hardware settings AFTER you change the ICC profile.
so by doing this i got a monitor i am very very happy with. the color made me want to puke before, but now it is as ok as my old awesome TN monitor. again, it is not as good color fidelity as an ips but it is much much cheaper with very high response time.
one last HUGE negative is the power on led light is super bright and you cant turn it off from the menu. i just put a little sticker over it.
so after all this i ended up with a 355 $ ish gsync monitor which i am very happy with. i am glad that my panel has no issues that i can notice, definitely no dead pixels or any bothersome bleeding. when i play videogames i dont notice anything bad at all.
i hope this helped, i really benefitted from this thread and thought maybe i could helpsomeone in my situation.
please feel free to rewrite this information more legibly and intelligently than i did!
