Is the HP Chromebook 14 good for schoolwork?

Yes for web-based work: Google Docs, Classroom, email and video calls run fine. It struggles with heavy multitasking or installed Windows software, since Chrome OS uses web and Android apps.

Can it run Windows programs like Microsoft Office?

Not natively. You can use Office on the web or Android app versions, but full desktop Windows apps won't install on Chrome OS.

How much RAM does it have, and can I upgrade it?

It comes with 4 GB of LPDDR4 memory, which is soldered to the board. There is no memory upgrade path, so buy with that limit in mind.

Does it have USB-C or an HDMI port?

No. It has two USB-A ports, a microSD card reader and a headphone jack, so you need an adapter for USB-C devices or an external monitor.

Is the screen good for watching video?

It handles 720p and 1080p streaming, but the 1366x768 resolution and modest panel mean it isn't sharp or bright. It is fine for casual viewing, not photo or video editing.

How does it compare with the Acer Chromebook 314?

They share the same class of Celeron processor and 14-inch 768p screen. The HP has a slightly more compact body; the Acer is often cited for a better keyboard, so try both if typing comfort matters.
