I have a much nicer (expensive), larger and wider curved monitor at work, but I wanted something at home without breaking the bank, and Acer has always been a reliable go to for budget monitors. You cannot beat the price. It was well packaged and easy to set up, felt like good quality. I did have to tweak settings to get it to look the way I prefer, and there is plenty of flexibility to do that. Using with Windows 11 laptop.
I am not a gamer, so I cannot comment there, and I don't have experience with 4k, so I cannot say where it falls short. I prefer a wider and shorter ratio, but I knew what I was getting in advance of course.
Its generally better for video and graphics than for text. I will be very content to watch television and movies on this monitor, the colors and balance, resolution and pitch make videos look quite nicer than I expected. My laptop screen renders fonts quite well, so this was a step back but met my expectations for the price point, and again its very customizable, so you can adjust to find your favorite combination of sharp and smooth fonts and contrast, etc.
REVISED: the speakers on this monitor are really funny, I didn't expect anything fancy of course, but they can barely get 60% of the volume of my laptop, which doesn't have particularly impressive sound itself. I literally cannot even hear a typical television show on full volume. Not a big deal at this price point, I expect to have to use external speakers... but something a little laughable.
Overall very pleased. It's a 4 because its supposed to be a 4 (low price), but a 5 for the value.
