Both the Alienware AW3423DWF and the Samsung Odyssey G5 34" (C34G55T) made our Top 5 Ultrawide Gaming Monitors, at #4 (best value) and #5 (best budget). QD-OLED ultrawide at the most accessible price. 34" 165Hz with excellent colors, the gateway to premium ultrawide gaming. 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.
