Dell Alienware AW3423DWF Review: 3440×1440 165Hz FreeSync QD-OLED UltraWide Curved Gaming Monitor

The Dell Alienware AW3423DWF is a 34" 3440x1440 165Hz FreeSync Premium Pro ultrawide curved gaming monitor based on a QD-OLED panel.

Bottom Line

The Dell Alienware AW3423DWF is one of the best gaming monitors available. It undercuts the AW3423DW model by $200 yet offers virtually identical image quality and performance, as well as additional features.


Update: There’s a new critical M3B106 firmware update: “Fix to intermittent screen corruption and image degradation during heavy graphical load.”

There’s no doubt that the Dell Alienware AW3423DW is one of the most popular gaming monitors thanks to its QD-OLED panel that’s paired with the popular 34″ 3440×1440 ultrawide form factor and a reasonable price.

Now, the new AW3423DWF version uses the same panel, but without the dedicated G-SYNC module, which has its advantages and disadvantages. So, let’s see how the two compare!

Image Quality

As it uses the same panel, the AW3423DWF offers the same viewing experience as its predecessor, which implies flawless 178° viewing angles, precise Delta E < 2 factory calibration and a wide color gamut, covering 99.3% DCI-P3 and ~95% Adobe RGB color spaces with a relative ~149% sRGB gamut size.

You’ll also find dedicated sRGB and DCI-P3 color modes in the OSD (On-Screen Display) menu under the ‘Creator’ presets. These modes clamp the gamut to their respective color space and allow for brightness and gamma adjustments.

Next, you get an excellent brightness of 250-nits for a 100% white window, up to ~550-nits for 10% windows and around 1000-nits for 1 – 3% white windows, which results in vivid and punchy highlights.

This means that in comparison to LG’s W-OLED panels, you get a higher sustainable brightness for a 100% window and less aggressive ABL (Automatic Brightness Limiter), allowing for a brighter SDR image during everyday use.

While the AW3423DWF can get brighter than LG’s panels with small highlights, some W-OLED displays can achieve a higher brightness with 10% white windows. Still, due to the overall higher luminance and more saturated colors (which further increase perceived brightness), the Dell Alienware AW3423DWF appears generally brighter.

Naturally, one of the main advantages of OLED technology is the basically infinite contrast ratio as each pixel produces its own light and can be individually switched off for true blacks.

This also means you won’t get any backlight bleeding, IPS/VA glow, blooming, scanlines or other visual artifacts associated with LED-backlit LCDs.

When you combine its wide color gamut, high brightness and infinite contrast ratio, the Dell Alienware AW3423DWF undoubtedly offers an incredible HDR viewing experience.

There are two HDR modes: DisplayHDR 400 TrueBlack and HDR Peak 1000.

While HDR-1000 allows the screen to get brighter, it can trigger ABL in some scenes. HDR-400 is not as bright but offers a more consistent HDR image without ABL. The best option will vary from content to content and your personal preference.

If you have an NVIDIA graphics card, you can improve HDR Peak 1000 accuracy by enabling ‘Console Mode’ and ‘Source Tone Map’, and decreasing the ‘contrast’ to ’64.’

Update: There’s a new firmware update that improves the DisplayHDR 1000 preset and reduces fan noise.

The 21:9 ultrawide aspect ratio further improves the immersion by providing you with an extended field of view in compatible games and video content. However, keep in mind that unsupported content will have black bars at the sides of the screen.

Luckily, most games support 21:9 resolutions (either natively or via mods), apart from a few competitive titles (mainly StarCraft, Diablo 2 Resurrected, Overwatch and Valorant).

Further, the 3440×1440 resolution results in a pixel density of 110 PPI (pixels per inch) on the 34″ viewable screen of the Dell Alienware AW3423DWF monitor. This means that you get plenty of screen space with sharp details and text, and no scaling necessary.

Now, this QD-OLED panel has a peculiar triangular RGB subpixel layout that results in visible green/reddish color fringing on tiny text and thin lines. In games and videos, this isn’t noticeable, but if you plan on using the screen for something like coding and you’re sensitive to this type of visual artifact, it might bother you a bit.

QD OLED Subpixel Layout

Using ClearType, Better ClearType or Mac/FreeType, you can alleviate this issue in some applications a bit.

Another drawback of the panel is the risk of permanent image burn-in. However, Samsung’s QD-OLED panels are supposed to be more resistant to burn-in than LG’s W-OLED panels, and Dell even offers a three-year warranty that covers it.

So, as long as you use the monitor sensibly and use its integrated (and automatic) burn-in prevention features (Pixel Shift, Pixel Refresher and Panel Refresh), you won’t run into any issues.


freesync and gsync

The Dell Alienware AW3423DWF has a maximum refresh rate of 165Hz and it supports a variable refresh rate with a 48-165Hz dynamic range for tear-free gameplay.

It has AMD’s FreeSync Premium Pro certification, but it’s not officially certified by NVIDIA as ‘G-SYNC Compatible.’

Regardless, VRR works the same with all compatible graphics cards without any issues – apart from the VRR near-black gamma shift that affects all OLED panels; it can only be observed in particularly dark scenes, it’s subtle and rare, and won’t bother most gamers.

Next, OLED panels have a virtually instantaneous pixel response time speed, so you won’t see any overshoot or trailing artifacts behind fast-moving objects.

So, how does the performance compare to the AW3423DW, which has a native G-SYNC module?

In truth, there’s no big difference. The AW3423DW has a bit wider VRR range of 30-175Hz, but you’re not going to notice the 10Hz maximum refresh rate difference, while the AW3423DWF uses LFC below 48FPS (47FPS tripled to 141Hz, for instance) to prevent tearing anyway.

Generally, the main advantage of the G-SYNC module is variable overdrive, which changes the overdrive on the fly according to the frame rate for optimal response time performance. However, since OLED panels have instantaneous pixel response time speed regardless of the refresh rate, variable overdrive is not necessary here.

Finally, both the AW3423DW and the AW3423DWF have imperceptibly low input lag, so you won’t be able to notice any delay between your actions and the result on the screen.


Dell AW3423DWF OSD Menu

Beneath the bottom bezel of the screen, there’s a directional joystick for quick and easy navigation through the OSD menu.

Useful gaming features include Dark Stabilizer (improves visibility in dark scenes), crosshair overlays, various picture presets (including three customizable profiles), on-screen timers and a refresh rate tracker.

Unlike the AW3423DW, the AW3423DWF model supports Picture in Picture and Picture by Picture, and has some advanced image settings, such as hue, saturation, aspect ratio (21:9, 4:3 and auto) and sharpness – but it doesn’t have an ambient light sensor.

Of course, you’ll find the standard picture adjustment tools, such as brightness, contrast, gamma, color temperature, input source (including auto-detection), etc.

It also has ‘Console Mode’, which allows you to adjust RGB, gamma and Source Tone Map (allows HDR content to be tone mapped by the source device).

Another feature that’s not available on the AW3423DW is Alienvision, which places a rectangle in the center of the screen with different image enhancements:

  • Night – improves visibility in dark scenes
  • Clear – increases sharpness
  • Chroma – applies a heatmap
  • Crosshair – places a crosshair

You can adjust the rectangle size and some other parameters of this feature in Dell’s Alienware Command Center desktop application.

Finally, the backlight of the monitor is flicker-free and there’s an integrated low-blue light filter.

Design & Connectivity

Dell AW3423DWF Review

The stand of the monitor is sturdy and versatile with up to 110mm height adjustment, +/- 20° swivel, -5°/21° tilt and 100x100mm VESA mount compatibility, while the screen has a moderate 1800R curvature for added immersion.

While the design of the AW3423DWF is slightly slimmer than that of the AW3423DW, it uses the same anti-reflective screen treatment that prevents reflections without adding any graininess to the image as matte coatings do.

However, under direct lighting, it diffuses the light and makes blacks appear somewhat grayish, so it’s best to view it in a dark room or make sure no light is pointed directly at the screen.

Both monitors feature Dell’s AlienFX RGB lighting.

The RGB elements on the AW3423DW model include the Alienware logo and ring at the rear, the power button and a small LED strip beneath the bottom bezel, whereas the AW3423DWF variant doesn’t have that LED strip and it illuminates the number ’34’ instead of the ring at the back.

Connectivity options include two DisplayPort 1.4 inputs, one HDMI 2.0 port, a headphone jack, an audio line-out and a quad-USB 3.0 hub (1 upstream + 4 downstream).

Since the Dell Alienware AW3423DWF version doesn’t have a G-SYNC module, it has user-updatable firmware via USB and one less cooling fan. It still has one cooling fan for the panel, but it’s quieter than the G-SYNC one.

Note that the AW3423DWF has a true 10-bit panel, but it’s limited to 8-bit at 100Hz (120Hz via custom resolution). However, with HDR content, you get GPU dithering (8-bit + 2-bit FRC), which is indistinguishable from native 10-bit. In contrast, the AW3423DW model is limited to 144Hz at 10-bit.

HDMI 2.0 is limited to 100Hz at 3440×1440, but it supports 120Hz at 2560×1440 for the PS5 and Xbox consoles. VRR is also supported over HDMI via FreeSync for AMD GPUs and compatible Xbox consoles.

It also supports 4K HDR on the consoles, but only at 60Hz – the AW3423DW doesn’t support HDR on the Xbox consoles at all, while both monitors support 1440p 120Hz HDR on the PS5.

Price & Similar Monitors

The Dell Alienware AW3423DWF price amounts to $1,100, which is excellent value for money. It’s $200 cheaper than the AW3423DW model.

There are 6 monitors that use the same QD-OLED panel, offering a similar image quality and performance. However, they still have some differences in features, warranty, connectivity options, price, HDR accuracy, etc. Here’s how they compare:

The pricing and warranty can vary by region. Generally, we recommend going with the Dell AW3423DWF due to its price and warranty that covers burn-in.

Note that ASUS released a 34″ 3440×1440 240Hz ultrawide 800R curved monitor based on LG’s W-OLED panel, the ROG Swift PG34WCDM.

We’re also expecting more 34″ and 39″ W-OLED models, as well as monitors using Samsung’s third-gen 34″ 3440×1440 240Hz QD-OLED panel in 2024. Check out our OLED monitors article for more information.

If you’re looking for something similar, be sure to check out our best ultrawide monitors and best HDR monitors buyer’s guides for more monitors and information.

The LG OLED42C2, the ASUS PG27AQDM, the Samsung Neo G9, the Neo G7, the Innocn 27M2V and 32M2V are all worth considering in this price range.

Here’s a summary of how the AW3423DWF compares to the AW3423DW.
