Same summary

The Samsung S27HG402EU monitor with a 27-inch IPS screen and a high refresh rate of 300 Hz is well-matched for demanding gamers and users who value smooth images and responsiveness. Due to its Full HD resolution, it is suitable for gaming and everyday home use, but less so for detailed text work or for users who expect extreme sharpness during long hours of office work. The high speed and FreeSync Premium are an advantage in fast, dynamic scenarios where a smooth image without stutter is key.

User view

It is also suitable for home users who want a spacious work surface and multitasking, although full use of the diagonal size makes more sense for more dynamic tasks than for editing long texts. When choosing, it is recommended to consider the organization of your work desk and the optimal distance to the screen; you can read more about this in our guide to choosing a monitor size .

Answers to frequently asked questions

Who is a 27-inch monitor with Full HD resolution suitable for?

A 27-inch diagonal monitor with Full HD resolution is suitable for users who want a large image for gaming and multimedia, but are not particularly focused on detailed office work or graphic design, where a higher resolution is more important.

Does the high refresh rate of 300 Hz affect everyday work or just gaming?

The biggest advantage of 300 Hz is noticed by gamers in fast-paced action games where rapid movements are crucial, but otherwise the high frequency can provide smoother scrolling even in normal use, but this is not necessarily a deciding factor for everyone.

Is this monitor suitable as a primary display for working from home?

As a primary display for a home office, the monitor is particularly suitable in environments where very high text sharpness is not a priority, such as video conferencing and basic office tasks. For more practical advice, check out our guide to choosing a monitor for working from home .

What do I need to know about placement and distance to this monitor?

For a 27-inch monitor, the optimal placement is achieved when the distance to the eyes is approximately 60-80 cm, as this maintains comfortable visibility and reduces eye strain.

Can this monitor be used as part of a dual display?

The monitor can be used in a dual setup, as it has the appropriate connectors and standard VESA support, allowing you to combine it with another monitor of similar dimensions.
