Acer Acer SB220Q bi 21.5 Inches Full HD (1920

First things first: please treat this review as a "3.5 star", which is what I would rate it if Amazon allowed me to. My main issue with this screen is that it has to be the sorriest excuse of an IPS/AHVA/PLS panel I've ever seen. The viewing angles are actually so bad for left/right that there is only a very small position where I can leave my head so that there is no discolouration on the sides, worse than any TN panel I've ever seen. Also, it looks like there is a lot of excess light directly off center to your head's position, as if there is backlight bleed that shifts as you move your head left and right while staring at the screen. Since this was purchased to be my second monitor, it isn't that big of a problem to ME specifically... but it also means it's impossible to keep my head in the perfect position, due to it being off-center to me. I actually had to tilt the screen somewhat sideways (instead of being flush next to my main monitor) so that the sides would mostly look normal in terms of colour. Now I WILL admit that it is possible this is a defect with my actual screen, possibly some problem with backlight bleed or something, but since this is my only sample size, I must rate it accordingly. If Acer has a problem with my statements, they should step up their quality control game and not let a monitor like this pass inspection for sale. Now, the good! For a breakdown, I've rated this a 4/5 for gaming, 3/5 for picture quality, and 5/5 for brightness, here's my take on each: - The input lag is quite low; there is no system lag while working on it. Being above 60Hz also gives it a solid edge for gamers. Gamers generally care less about viewing angle issues like what I described, so as a gaming screen this should not be too bad. Unfortunately I still cannot ignore the viewing angle problem due to how bad it is, and I will never rate any screen below 120Hz as 5 stars for gaming, so it settles at 4. - Picture quality is actually quite good. The contrast is great and the colours very crisp - if the viewing angles and backlight shenanigans were a non-issue i would probably even rate this 5 stars (largely considering the price), but alas, 3 stars. - For brightness, it's certainly bright enough for my needs, though I've not used it in direct sunlight. The anti-glare works well and it keeps its picture quality and visibility perfectly fine even with a flashlight shone at it. I cannot ask for more, so full marks here. All in all, for $90 I cannot truly complain. It does its job of being a screen for discord, watching videos/anime, and handling my stream alerts/notifications. It's light and easy to set up, the on/standby light is not bright yet still well visible, so not distracting in a dark room. Unfortunately viewing angle issue and discolouration it produces ALONE is enough for me to say consider other options, but the rest of the screen pulls it up a bit. If this is going to be your main monitor, and you are not someone who does little but game on your computer? Stay far away. If you need a cheap, decent screen for gaming or this is going to be a low-importance second monitor? I'd say it's up for consideration, if only because it's 75Hz at this price point.
