LG UltraGear 45GX950A-B OLED Monitor vs Samsung Odyssey Neo G9 57"

The LG 45GX950A-B is the safer pick for most gamers: OLED contrast, 0.03ms response and a 5K2K panel that drops to 330Hz in WFHD mode. The Samsung Odyssey Neo G9 is far wider and brighter, with 2048-zone Mini LED and 240Hz, but owner reports of dead pixels, half-screen blackouts and flicker are common enough to matter. Buy the LG for image quality and reliability; buy the Samsung only if you want the widest, brightest desktop and can accept QC risk.

  • Choose the LG 45GX950A-B if you want OLED blacks, near-instant response and a sharp 5K2K 21:9 panel that can switch to 330Hz for competitive play.
  • Choose the Samsung Odyssey Neo G9 if you want the widest 32:9 field of view, very high brightness and Picture-by-Picture for a multi-window desktop.

What reviewers say

LG UltraGear 45GX950A-B OLED Monitor

  • 4.5 / 5109 ratings

Owners rate it highly, praising the sharp ultrawide OLED picture and the flexibility of dual-mode refresh. Complaints center on the aggressive curve, the limited port selection and the desk space it demands.

What people mention
  • Picture qualityPraisedOwners call the 5120x2160 OLED panel sharp and vivid, with deep blacks and strong HDR.
  • Dual modePraisedSwitching to 330Hz at WFHD is seen as a real advantage for fast competitive games.
  • CurveMixedSome like the immersive 800R wrap; others find it too aggressive for desktop work.
  • PortsCriticisedBuyers note the single HDMI 2.1 and one USB port are thin for a monitor this size.

Samsung Odyssey Neo G9 57"

  • 4.5 / 5655 ratings

  • BrightnessPraisedReviewers say it is bright enough for daytime use and handles HDR well.

Questions and answers

Which is better for competitive shooters?
The LG. Its 0.03ms response and 330Hz WFHD mode beat the Samsung's 1ms and 240Hz, and OLED has no backlight smearing.
Which has better picture quality for single-player games?
The LG for contrast and dark scenes, since per-pixel OLED avoids blooming. The Samsung wins on raw brightness and screen width.
Which lasts longer?
The Samsung's Mini LED backlight does not carry OLED burn-in risk, but owner reports of dead pixels and blackouts are a real concern. The LG's OLED can dim static elements over years of desktop use.
Is the Samsung worth stepping up to for productivity?
Only if you need 32:9 width and Picture-by-Picture. The LG's 5K2K height and USB-C docking make it the easier single-cable work monitor.
Do I need a high-end GPU for either?
Yes for the Samsung at 240Hz Dual UHD. The LG is more forgiving because WFHD 330Hz mode lowers the rendering load.
Which is better in a bright room?
The Samsung. Its Mini LED backlight reaches far higher brightness and its matte coating handles glare better than the LG's OLED.
