Con A maximum refresh rate of 60Hz can be a concern for some
A 60Hz monitor, while sufficient for most people in most cases, can still cause issues with fast-moving objects on screen. It's especially important with things like gaming where the ability to react to events happening on the screen quickly is important.
Con IPS glow
IPS glow is the light on the sides or corners of the screen that can reduce some of the peripheral detail.
