The product, explained
About the LG 27" UltraGear™ OLED 480Hz QHD Gaming Monitor
LG 27GX790A-B.AEK is listed in the computer monitors category. The recorded specifications include display diagonal: 68.6 cm (27"); display resolution: 2560 x 1440 pixels; panel type: WOLED; maximum refresh rate: 480 Hz. This entry covers manufacturer code 27GX790A-B.AEK. Specifications relate to this exact source record; other editions or packages may differ.
The 68.6 cm (27") display is specified at 2560 x 1440 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
The listed maximum refresh rate is 480 Hz. To use it, the source device, cable, resolution and input must all support the intended mode. Refresh rate is separate from response time and input lag.

Which exact version does this page cover?
This page identifies LG 27" UltraGear™ OLED 480Hz QHD Gaming Monitor using manufacturer code 27GX790A-B.AEK. Check that code, configuration and supplied accessories against the retailer listing. Related-version reviews are labelled separately and do not contribute to this version’s score.
What is the listed display diagonal for LG 27" UltraGear™ OLED 480Hz QHD Gaming Monitor?
The source specification records display diagonal as 68.6 cm (27"). This is a specification, not an independent performance measurement. Check the exact model and the original critic reviews for real-world results.
What is the listed display resolution for LG 27" UltraGear™ OLED 480Hz QHD Gaming Monitor?
The source specification records display resolution as 2560 x 1440 pixels. This is a specification, not an independent performance measurement. Check the exact model and the original critic reviews for real-world results.
Where can I compare prices for LG 27" UltraGear™ OLED 480Hz QHD Gaming Monitor?

Does a higher refresh rate make every app better?
It can make movement feel smoother, but benefits depend on the computer, connection and the activity.
Can I use a USB-C monitor with any laptop?
Not necessarily. Check the laptop port supports the required display mode and charging level.
Is a curved monitor always more immersive?
It depends on size, desk distance and use. Try it for text and multi-window work, not only video.
How should I use the specifications alongside reviews?
Use the recorded features to check compatibility and make a shortlist. Read the original reviews for measured performance, everyday use and the tested configuration.
