Will it go off when viewing at different angle?
If it will then it is just ips glow

Maybe you can read out more here
I think upper left is slight bleed, lower right excessive bleed. No matter where I view it from, the lower right edge is affected quite badly, and the colors are washed out/hue change by 5% at the extreme right corner due to the brightness, and it's visible even when I view bright webpages or watch videos under daylight.
Upper left maybe 1%, not really visible unless you have dark background or watching real closely at it. Almost not visible during daytime.
The other corners are minimal bleed/ips glow. These areas need black background, plus you must be in night time with the lights turned off to see a real change. It's not going to be a problem if I turn on the lights.
If it's not for the excessive delay from hachi tech, and there's a real firmware issue (starting from July 2016 batch acer fixed a 'line down the middle issue' and mine is the Feb batch), maybe I can think about accepting my fate, lol. In any case, I am going to try and return this model and see if I can get a more recent batch, to at least fix the firmware issue and play the monitor lottery again.
PS: Just FYI, I'm not sure how subjective my eyes are compared to the normal public, I always did feel that I'm more sensitive to light changes. Still, the monitor is $1000 and it better be the best frigging monitor ever.
