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

It is usable for office work and video, but text looks less crisp than on a 24-inch 1080p or a 27-inch 1440p monitor. If sharp text matters, a higher resolution panel is the better fit.

Is the 100 Hz refresh rate good for gaming?

It is a clear step up from 60 Hz for casual and console gaming. Competitive players will want a faster panel with a lower response time.

Does it have built-in speakers?

No. You need external speakers or headphones connected to your computer.

What ports does it have?

It offers HDMI and VGA. HDMI handles modern laptops and consoles, while VGA suits older PCs.

Can I mount it on a monitor arm?

Yes, it has a standard VESA mounting pattern, so you can replace the stand with an arm or wall mount.

Is it good for photo or video editing?

It is fine for casual use, but the VA panel and 1080p resolution are not ideal for color-critical work. An IPS panel with higher resolution suits editing better.
