However, we do offer the Dual Controller feature on this monitor, which allows you to control two devices connected to the monitor using a single keyboard and mouse, which might be useful for managing multiple systems.

Q: QuestionIs this a glossy or matte screen?(1 answer)
A: AnswerHi there, Caboose. Thank you for reaching out with your question. The LG 27GX790A-B gaming monitor features a surface treatment that is Anti-Glare, with a low-reflection front polarizer, which helps minimize reflections. This means that the screen is designed to reduce glare, offering a more matte-like finish, even though the display itself is OLED. https://www.lg.com/us/monitors/lg-27gx790a-b-gaming-monitor#pdp_specs If you have any further questions or need additional assistance, please feel free to send us a private message on Social Media @LGUSSupport, and our team will be more than happy to assist you further.

LG please fix 24" mode.
Great monitor for competitive fps games. My only complaint is that the 24" mode does not support the correct pixel mapping like the asus or sony does. For those other monitors, they switch the resolution to 1332p, but for the LG, it remains 1440p so the overall image is quite blurry and unusable for me. Hopefully this can be fixed with a firmware update, but LG typically isn't very good with those.
