  • Our take on the LG UltraGear 45GX90SA-B 45" Curved OLED Gaming Monitor

    The LG UltraGear 45GX90SA-B is a 44.5-inch curved OLED gaming monitor with a 21:9 WQHD (3440 × 1440) panel and an 800R curve that wraps the view around you. It pairs a 240Hz refresh rate with a 0.03ms GtG response time and covers 98.5% of DCI-P3, with VESA DisplayHDR True Black 400 and a 1.5M:1 contrast ratio for deep blacks. G-Sync compatibility, FreeSync Premium and VESA Adaptive Sync cover both GPU camps, and webOS 24 adds streaming apps, AirPlay and screen sharing without a PC. It suits sim racers, immersive single-player gamers and anyone who wants one screen for both work and play; against flat 34-inch ultrawides it is far more immersive, but its 3440 × 1440 resolution is less sharp than a 5K2K panel at this size and OLED carries burn-in risk for static desktop work.

    Questions and answers

    Is 3440 × 1440 sharp enough on a 45-inch screen?
    Pixel density is about 83 PPI, similar to a 27-inch 1080p monitor. Text and fine UI look softer than on a 34-inch 1440p ultrawide; games and video look fine, but heavy spreadsheet or coding work shows the gap.
    Does it work with both Nvidia and AMD graphics cards?
    Yes. It is G-Sync compatible and supports AMD FreeSync Premium and VESA Adaptive Sync over DisplayPort and HDMI 2.1, so variable refresh works on either GPU brand.
    Can I use it without a PC?
    Yes. webOS 24 runs streaming apps, a web browser and screen sharing over Wi-Fi, and AirPlay works from Apple devices. Voice recognition needs the Magic Remote, which is sold separately.
    What connections does it have?
    Two HDMI 2.1 ports, one DisplayPort 1.4, a USB-C upstream port with 65W power delivery, two USB 2.0 downstream ports, Ethernet and a headphone jack.
    Should I worry about OLED burn-in?
    Static elements like taskbars and HUDs can leave marks over long sessions. LG includes screen-shift and brightness-limiting features, but a mix of content and hiding static bars reduces the risk.
    How does it compare with a 49-inch super ultrawide?
    The 45-inch 21:9 is easier to drive and has a taller screen than a 32:9 49-inch, but less horizontal sweep. The OLED panel gives it better contrast and response than most LCD super ultrawides.
    Where is the LG UltraGear 45GX90SA-B 45" Curved OLED Gaming Monitor cheapest?
    At Amazon, for $1,149.99, as of our latest check.
