How they differ in real use
Built from our ultrawide gaming monitors scoring, each product's published specifications, and verified owner feedback — not hands-on testing.
Both the Alienware AW3425DW and the Samsung Odyssey G5 34" (C34G55T) made our Top 5 Ultrawide Gaming Monitors, at #3 and #5 (best budget). A generation newer than the AW3423DWF below it: the same 34" 3440x1440 QD-OLED format with an 1800R curve, but at 240Hz instead of 165Hz with a 0.03ms response, plus two HDMI 2.1 inputs and both FreeSync Premium Pro and G-Sync Compatible certification. PCGamesN scores it 9/10 and singles out text far sharper than early QD-OLED panels, and RTINGS reports near-instantaneous response times at any refresh rate. It sits below the 45" LG on sheer size and immersion and costs more than the AW3423DWF, and it has no USB-C video input or KVM switch; in a bright room its blacks take on a purple tint. The entry point to 34" ultrawide gaming: a 3440x1440 VA panel at 165Hz on a deep 1000R curve, with roughly 2,500:1 native contrast, for a fraction of the price of every OLED above it. RTINGS credits it with low input lag and excellent native contrast for dark-room play. Against the OLED picks it gives up speed (VA smearing in dark scenes), HDR and color range, and its tilt-only stand and 100Hz cap over HDMI are the clearest corners cut to reach its price.
We score ultrawide gaming monitors on Immersion (30%), Image Quality (25%), Speed (25%), Features (10%) and Value (10%). On that basis the Alienware AW3425DW totals 9.4 out of 10 and the Samsung Odyssey G5 34" (C34G55T) 7.7. The widest gap is Image Quality, where the Alienware AW3425DW scores 10 against 7 for the Samsung Odyssey G5 34" (C34G55T): resolution and colors. Speed also separates them: 9.8 for the Alienware AW3425DW versus 7 for the Samsung Odyssey G5 34" (C34G55T). The Samsung Odyssey G5 34" (C34G55T) claws back ground on Value.
