What published reviews found

Tom's Hardware was strongly positive. It described the picture as a clear step beyond any LCD it had seen, said motion looked close to what you would expect from a 240Hz display despite the 165Hz cap, and found color accuracy good enough that no calibration was needed. It also called HDR performance strong and noted that HDMI 2.0 is a limitation for console players. The deep stand base was its other complaint.

PCWorld reached a similar conclusion, calling it the ultrawide gaming monitor to buy at its price. It did flag two weaknesses. The QD-OLED subpixel arrangement produced fringing and pixelation around small fonts, which matters if you read a lot of text on the screen. Its HDR measurement peaked at 306 nits, which falls short of mini-LED competitors in bright scenes. PCWorld also pointed out that two DisplayPort inputs allow two PCs to run at full refresh rate, though there is no USB-C input.

MonitorNerds reported roughly 4ms of input lag at 165Hz and a factory color error of 1.51 delta E, and listed burn-in as a significant concern that calls for careful use. Tom's Guide treated the AW3423DWF as a small update to the earlier AW3423DW, with the main change being a lower price.

Price and availability

Both Tom's Guide and PCWorld gave a launch price of $1,099 in late 2022. On October 6, 2026, Dell's US product page listed it at $899.99 and showed it as sold out. Retail prices and stock change often, so check current listings and our monitor deals roundup before you buy.

Who it's for

This monitor suits PC gamers who care most about contrast and color and have a GPU able to push 3440x1440 at high frame rates, such as the systems in our high-end gaming PC build guide. The burn-in panel exchange in Dell's warranty lowers the risk for people who worry about OLED longevity.

Consider skipping it if you do a lot of text-heavy work, play in a very bright room, or mainly game on a console, since HDMI 2.0 caps the refresh rate at 100Hz. If you want to avoid OLED entirely, the LG UltraGear 27GR93U is a 4K IPS option, though with much weaker contrast and HDR.

Bottom line

Published reviews agree that the AW3423DWF delivers image quality and motion clarity that LCD ultrawides struggle to match. The trade-offs are small-text fringing, modest HDR peak brightness, a big stand and the usual OLED burn-in question, which Dell's panel exchange coverage partly answers. It is a strong pick for contrast-focused PC gaming if you can find it near or below its launch price.
