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 Samsung Odyssey OLED G9 G93SC and the Alienware AW3425DW made our Top 5 Ultrawide Gaming Monitors, at #1 (best overall) and #3. The most immersive screen here: a 49" 32:9 QD-OLED at 5120x1440 and 240Hz with 0.03ms response, equal to two 27" 1440p monitors side by side and wider than the LG 45GR95QE's 45" 3440x1440 canvas. It is the same panel as the G95SC it replaces in this ranking, minus the smart TV apps and remote, which costs it a little on features but nothing on picture or speed. The trade-offs are a desk footprint of about 1.2 m, OLED burn-in risk and patchy 32:9 support in some games. 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.
We score ultrawide gaming monitors on Immersion (30%), Image Quality (25%), Speed (25%), Features (10%) and Value (10%). On that basis the Samsung Odyssey OLED G9 G93SC totals 9.5 out of 10 and the Alienware AW3425DW 9.4.
