I also just got this monitor and I'm definitely impressed by the 144Hz. However, since this is my first new monitor since 8 years, I am a little baffled by the IPS glow thing. Some people say it doesn't vary, some say it does. Now my model has no dead pixels and only some backlight bleeding, but the IPS glow is quite irritating. When I sit normally in front of the display, I can easily see it. Mostly on darker colors and mostly when the room isn't well-lit, but still: if you know it's there, you definitely spot it and it "washes" the colors out in a yellowish tone (and yes, it does go away when looking from somewhere else, further away, etc.). Now I was under the impression that you should only see the glow when viewing at angles, right?
Anyway, even with the glow I'm thinking about keeping it, but there's two things that make it a rather tough decision for me.
1) The monitor wasn't completely new. The packaging was re-used, the monitor hat some fingerprints on it and also about 35 hours of running time. This irritates me because I bought it as new and now I'm thinking someone already returned this one and I get a bad feeling because of it (because I'm thinking: why did this person return it?).. would this bother you?
2) Since 500 euros is quite a bit of money and I'm in for the long game (my last monitor held up for 8 years), I'm not sure if this is a reasonable investment. I've heard a lot of bad things about Acer and the quality control, and I'm wondering: is this a good long-term investment? With my last monitor I felt like that was a premium screen. With the Acer I'm just not so sure: the build quality seems alright, but when looking at details you see some issues. Funny example: on my monitor there seems to be a 1.5cm long string between the panel and the top bezel (have to see if I can get it out of there).
Anyway, I would be glad to get some input and tips from you guys. Someone in another forum said "people seem to have OCD with monitors" and I think that's definitely true for me. It's just that it's really expensive and I feel like it has to be the right thing for the next 5-8 years.
