    Great.
    Review is for the AOC Q27G3XMN 27" Mini LED. They have a bunch of monitors mixed here in the reviews.Coming from an IPS monitor it is amazing to see actual black colors in games again.The depth and colors are spot on in HDR mode. It took some fiddling between Windows setting and the super awkward 4 button OSD(on screen display) adjustment right next to the power button. Have to turn on HDR in Windows, HDR on the monitor and then adjust the windows HDR slider.It is not perfect with the dimming zones as there is plenty of bloom bleed in some settings like World of Warcraft. Things like if the something super bright goes behind the chat window the colors of the chat Window light up some. But the brightness is amazing. Going blind when I get flashbanged I'm CS2 and loving it. You can almost get a sense of how bright it is from the photo of BF2142 I uploaded. My old monitor was 250 nits I think and this does around 1100 nits according to some reviews.The motion is buttery smooth at 180hz and I have not noticed any ghosting which is supposed to plague low quality VA panels.Love it=]The side by side in the video I uploaded is next to a 15 year old Dell monitor but the video does not do it justice. I am a terrible CS2 player but I cannot stop playing because it looks so pretty.(Update) After a month I decided to try the DP cable that came with it instead of my old DirektKabal 1.4DP cable and I got vertices lines so if you use the DP cable that came with it and you get vertices lines try to replace the cable.
