Alienware 39 5K OLED Gaming Monitor (AW3926QW) review

Alienware AW3926QW moves the OLED ultrawide up to 5K2K. Dell lists a 38.9-inch OLED panel at 5120 x 2160 and 165Hz, which works out to 143 pixels per inch, against 110 ppi on the 34-inch AW3426DW. A dual resolution mode drops to 2560 x 1080 at 330Hz for fast competitive games. HDR support matches its smaller sibling with VESA DisplayHDR True Black 500, Dolby Vision and 1300 nits peak brightness, and Dell lists 99% DCI-P3. Unlike the AW3426DW, it has a USB-C upstream port with DisplayPort 2.1 Alt Mode and Power Delivery up to 90W, so a laptop can connect and charge over one cable, and the main video input is DisplayPort 2.1. The 1500R curve is tighter than the 34-inch model's 1800R. Dell lists a three-year warranty that covers OLED burn-in. Running 5K2K at high frame rates takes a powerful graphics card. Dell.com listed it at $1,099.99 when we checked. We compared documented features and published prices only.
