Is 1080p sharp enough on a 27-inch monitor?

It is usable for office work and video, but text and fine detail look softer than on a 1440p 27-inch screen. If you read a lot of small text, a higher resolution is worth considering.

Can the USB-C port charge a laptop?

Acer does not list USB-C power delivery wattage for this model, so treat it as a video and data connection. Check the port's power spec before relying on it to charge a laptop.

Is 120 Hz good for gaming?

It is a clear step up from 60 Hz for casual games and makes motion smoother. Competitive players will want a 144 Hz or faster panel with a lower response time.

Does it have built-in speakers?

Yes, it has built-in speakers, which is enough for calls and basic audio. Most buyers will still prefer headphones or external speakers for music and games.

Can I mount it on a monitor arm?

Yes, it has a 100x100 mm VESA mount and weighs about 8 lb, so most arms and wall mounts will hold it.

Expect the monitor, stand, and the cabling Acer ships for the region, typically HDMI. Confirm the exact bundle with the seller if you need a USB-C or DisplayPort cable.
