Same summary

The LG UltraGear 27GX704A-B OLED monitor with a 27-inch diagonal and QHD resolution is particularly suitable for users looking for a visual experience with high sharpness and smooth display. With a 240 Hz refresh rate and support for FreeSync and G-Sync, it is particularly interesting for demanding gamers and those who appreciate excellent responsiveness in fast-paced scenes. Due to OLED technology, it offers a superior contrast ratio and vivid colors, but when used for several hours with extremely static content (e.g. all-day office work with the same windows), the question of long-term display durability may arise. In work environments with the need for multiple monitors or more accurate color calibration, it is recommended to consider the layout and ergonomics.

Answers to frequently asked questions

Is an OLED monitor suitable for everyday office work?

OLED monitors are excellent for displaying images and colors, but when used for long periods of time with mostly static content (for example, Excel, document editing), they can cause a so-called "burn-in" effect in the long term, so we recommend them for combined or dynamic use.

What is the advantage of 240 Hz refresh rate on this monitor?

With a high refresh rate of 240 Hz, the monitor is well suited for fast-paced games and e-sports, as it provides an extremely smooth image and less motion blur.

Can the monitor be easily connected to different devices?

The monitor supports modern HDMI, DisplayPort and USB-hub connectors, allowing connection to most computers, laptops or game consoles.

What do I need to consider if I want to use two such monitors at the same time?

It's important to check that your graphics card supports the selected number of displays at QHD resolution and high refresh rate, and our dual monitor setup guide will also be helpful when setting up two monitors .

What viewing distance is a 27-inch monitor optimal for?

For a 27-inch QHD monitor, the recommended eye distance is approximately 60 to 80 cm, as this optimizes text sharpness and reduces eye strain. For more information on choosing the right size, see our monitor size guide .
