The Alienware AW3423DW offers a refresh rate of 175Hz, with a resolution of 3440×1440 and supports G-Sync.
Taken from TPU … Remember that 34-inch QD-OLED monitor that Alienware announced at CES earlier this year? The company has finally worked out how much it’s going to charge for it, although there is still no fixed availability date. At US$1,299 the AW3423DW is going to be a $100 pricier than the AW3821DW, which sports a 38-inch Nano IPS panel with a resolution of 3840×1600, rather than the 34-inch QD-OLED panel with a resolution of 3440×1440 of the AW3423DW.
Obviously the two display technologies aren’t comparable, but it’s at least an indication of how pricy QD-OLED will be initially, compared to more traditional display technologies. Both displays feature G-Sync Ultimate, so it’s not as if Dell has tried to cut any corners here. The AW3423DW does offer a higher refresh rate of 175 Hz vs 144 Hz for the AW3821DW, which may be an advantage to some, but the official HDR certification is oddly enough only HDR 400 vs HDR 600, despite the fact that Dell claims it can deliver up to 1000 cd/m². That said, the black levels of the AW3423DW should be vastly superior, as should the colour gamut. The display is said to be available sometime early this spring, presumably in the US market first.
