Ultrawide OLED is the most immersive gaming experience a monitor can provide. The LG UltraGear 45GR95QE-B is a 45-inch 21:9 OLED at 800R curvature. The Samsung Odyssey OLED G9 stretches to 49 inches in 32:9 — effectively two monitors in one. Both have 240Hz refresh rates and OLED panels. They're not really the same product.
LG UltraGear OLED 45" 45GR95QE-B
The LG 45GR95QE-B is the better all-purpose choice — its 21:9 aspect ratio is widely compatible with games and apps, and the 800R curve delivers exceptional immersion without going full ultrawide. The Samsung G9's 32:9 is incredible for sim racing and trading, but many games don't support 32:9 and the experience becomes letterboxed.

Aspect Ratio and Compatibility
The 45GR95QE-B's 3440×1440 at 21:9 is supported by the vast majority of games — over 90% of modern titles support 21:9 ultrawide natively. The Samsung Odyssey G9's 5120×1440 at 32:9 is supported by fewer titles — many games will letterbox or pillarbox at 32:9.
For simulation games, racing sims, and flight sims, the 32:9 G9 is extraordinary. For general gaming across a broad library, 21:9 is more practical.
Curvature
The LG 45GR95QE-B's 800R curve is tighter than Samsung's 1800R G9. At 45 inches, 800R wraps significantly around your field of view, which most users find immersive for gaming. 1800R on the 49-inch G9 is a gentler curve that's more comfortable for productivity use.
Whether you prefer tight or gentle curvature is personal. Productivity users often prefer 1800R or less; dedicated gaming setups often go 800R.
OLED Panel Performance
Both monitors use WOLED (LG Display panels). RTINGS measured both at similar peak brightness — around 450–500 nits in HDR content across the full panel. Both achieve true OLED blacks.
The LG's 800R physical geometry and smaller 45" vs 49" size means the pixel density is slightly higher, which translates to slightly sharper text. For productivity work mixed with gaming, this matters.
Desk Requirements
The Samsung G9's 49" width requires a very large desk — at minimum 55" wide to accommodate the curve comfortably. The LG 45GR95QE-B is more manageable at 45", though still requires a sizable surface.
Viewing distance matters with curved ultrawides. Both monitors are best viewed from 80–100 cm. Any closer and the 800R curve of the LG can feel overwhelming; the G9's 1800R is more forgiving at close range.

FAQ
Can the Samsung Odyssey G9 run at 5120×1440 at 240Hz?
Yes, over DisplayPort 1.4 with DSC compression. HDMI 2.1 limits it to 5120×1440 at 120Hz. For 240Hz gaming, you need a DisplayPort connection.
Is 21:9 vs 32:9 a big deal for streaming video?
Most movies and TV are 16:9 or 2.35:1. On 21:9 you'll see thin letterboxing for some content. On 32:9 you'll see more letterboxing for most content. Neither is ideal for video; both are aimed at gaming.
