Is 100Hz worth it over a 60Hz monitor?

Yes for motion. The 100Hz panel shows less blur and lag in games and smoother scrolling than a 60Hz screen, though it is not a high-refresh gaming display.

Is Full HD sharp enough at 27 inches?

It is fine for documents, web browsing and video at normal desk distance, but text looks softer than on a 1440p 27-inch screen. Sit a little farther back if sharpness matters.

Does the IPS panel matter?

Yes. IPS keeps colors and contrast consistent when you look from the side, which helps when several people watch or you sit off-center. It also avoids the color shift of cheaper TN panels.

Can I adjust the stand height?

The stand is a simple tilt design with no height or pivot adjustment. If you need ergonomic positioning, plan on a monitor arm or a riser.

Does it work with a Mac or a laptop?

It takes a standard HDMI connection, so most laptops and Macs work with the right cable or adapter. There is no USB-C input, so you cannot charge a laptop through the monitor.
