The product, explained
About the LG 39GX90SA-W
LG 39GX90SA-W.AEK is listed in the computer monitors category. The recorded specifications include display diagonal: 99.1 cm (39"); display resolution: 3440 x 1440 pixels; panel type: OLED; maximum refresh rate: 240 Hz. This entry covers manufacturer code 39GX90SA-W.AEK. Specifications relate to this exact source record; other editions or packages may differ.
The 99.1 cm (39") display is specified at 3440 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 240 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.

No scored critic reviews have been imported for this product yet. This means review coverage is missing; it does not mean the product received a poor review.
What is the COR Score for LG 39GX90SA-W?

Which exact version does this page cover?
This page identifies LG 39GX90SA-W using manufacturer code 39GX90SA-W.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 39GX90SA-W?
The source specification records display diagonal as 99.1 cm (39"). 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 39GX90SA-W?
The source specification records display resolution as 3440 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 39GX90SA-W?
Use the retailer-offer section on this page for available matched offers. If no offer is shown, we do not currently have a verified price. Confirm model, stock, delivery and the final total at the retailer; coverage does not include every seller.
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.
