  • QuestionCan you really not wall mount this monitor? Is it because of the curve?

    Asked by Anonymous.

    • Answer I was able to mount it to an externa table mount that I previously had for my monitor that I replaced this with. I can't see why you wouldn't be able to use a wall mount. It might must be troublesome to get it mounted because of how big it is.

  • QuestionWhen viewing or streaming a movie, or video content, would you get the full screen 21/9 aspect ratio, or would you still get those black bars on the side? Also, would the image be stretched if you get the full screen watching movies?

    Asked by sufka28.

    • Answer Whether you get black bars on the sides on or the top and bottom of the LG UltraGear™ 45" OLED 240Hz 0.03ms G-Sync®/FreeSync™ Premium Pro Smart Gaming Monitor with DisplayHDR 400 TRUE BLACK - Black, Model # 45GX90SA-B when viewing or streaming a movie, or video content will depend on what aspect ration the movies, or video content are. The monitor has a native WQHD (3440 x 1440) resolution which is an aspect ratio of 21:9. When viewing 16:9 video content on a 3440 x 1440 screen, you will get black bars at the sides, because the content does not match the native resolution or aspect ratio of the monitor. Some movies have a 2.35:1 aspect ratio and those will also have black bars on the top and bottom on a 3440 x 1440 screen...^Ivan.

  • Questiondoes this monitor require an internet connection? i dont need the streaming services, i just want to connect it to my pc and game without all the extra bs. thanks.

    Asked by MichaelE.

    • Answer Hi there, MichaelE. Thank you for sharing your inquiry with us. We understand your inquiry regarding the connectivity and internet requirements for the 45GX900A-B monitor. We are happy to inform you that this UltraGear OLED monitor does not require an internet connection to function. Unlike smart monitors that feature built-in operating systems, this unit is a dedicated high-performance gaming display designed to be connected directly to your PC or console using the included DisplayPort 1.4 or HDMI 2.1 cables. Because this model does not include smart streaming platforms or webOS, you can enjoy the native 3440 x 1440 resolution and ultra-fast 240Hz refresh rate immediately without any requirement for Wi-Fi or ethernet setup. This allows you to focus entirely on your gaming performance and take full advantage of features like NVIDIA G-Sync compatibility, AMD FreeSync Premium Pro, and the 0.03ms response time with a simple plug-and-play experience. https://www.bestbuy.com/product/lg-ultragear-45-oled-qhd-240hz-0-03ms-g-sync-freesync-premium-pro-smart-gaming-monitor-with-displayhdr-400-true-black/JJ8VPZWYXR If you have any further questions about its features, please contact us on [email protected], and our team will be more than happy to assist you. —Renzo

  • QuestionSee images from the product ad. One says DP 2.1 but the specs are DP 1.4. Why the false advertising?

    Asked by JohnnyB.

    • Answer Thank you for pointing out that discrepancy. The fourth thumbnail image of a DisplayPort 2.1 port for the LG 45-inch UltraGear™ OLED WQHD 240Hz 0.03ms G-Sync Compatible 800R Curved Gaming Monitor with webOS, Model # 45GX90SA-B, is an entry error. The DisplayPort version for the DisplayPort on the monitor is DisplayPort version 1.4, as you have noted. We will have Best Buy correct that!...^Ivan.
