Today at Gamescom, Dell has officially launched its new flagship OLED gaming monitor, the Alienware 55. First demonstrated back at Computex, the display uses a 4K OLED panel featuring a 120 Hz refresh rate, making it among the fastest 4K monitors available. The Alienware 55 supports AMD’s FreeSync variable refresh rate technology, which is what sets the monitor apart from OLED UHDTVs, yet not in its HDR implementation.

The Alienware 55 is based on a 55-inch OLED panel featuring a 3840x2160 resolution, 400 nits peak brightness, a 130,000:1 contrast ration, a 0.5 ms gray to gray response time, as well as a 120 Hz maximum refresh rate. The screen can reproduce 98.5% of the DCI-P3 color gamut, which is comparable to accuracy of professional LCD displays. The monitor also has an anti-reflective coating with 2H hardness for additional clarity when used in bright days.

The key feature set of the Alienware 55 is a combination of its technologies as well as its size. OLED computer displays are rare in general, and this one is the industry’s first OLED monitors for gamers. The product is not without caveats though: despite the use of OLED technoloy, this is not an HDR monitor. In fact, Dell says nothing about Alienware’s 55-incher supporting HDR10 or Dolby Vision transports; so regardless of what the panel can do, it would appear that the monitor itself doesn't support any HDR input formats.

The Alienware 55 comes with three HDMI 2.0 inputs as well as one DisplayPort 1.4 connector, with the latter being the second oddity in today's announcement. With full 4:4:4/RGB color, DisplayPort 1.2 is limited to 60Hz; you need DisplayPort 1.4 for 4K@120Hz with 8bpc color. So for what Dell is doing, there's an error in the specifications or compromise somewhere. Either DisplayPort 1.2 is right and they're doing something akin to 4:2:2 choma subsampling to make 120Hz work, or this is not a true 120Hz monitor at all – and instead it's a 60Hz monitor with black frame insertion, a common tactic for TVs. At this point we're not sure which it is, and we've reached out to Dell for clarification.

Update: Dell has gotten back to us, confirming that their original spec sheet was wrong, and that the monitor comes with DisplayPort 1.4 rather than 1.2. So the display does in fact have enough bandwidth for 4K@120Hz with 8bpc color.

Moving on, the display has a quad-port USB 3.1 Gen 1 hub, a headphone output, and an S/PDIF line out. When it comes to audio, the display has two 14 W speakers that were co-designed with Wave Maxx Audio.

Just like other large displays, the Alienware 55 comes with a remote control to adjust brightness, regulate audio and perform other operations.

Dell will start sales of the Alienware 55 display starting September 30 at $3,999.99.

    Microsoft (Xbox Scarlett) & Sony (PS5) gave them a lay-up informing the press that their consoles target & support 4K@120hz. Like the Xbox One X today, they primarily intend to do that via HDMI 2.1 Reply

    With the LG 2019 OLED TVs now having G-Sync; this monitor is DOA. Reply

    The HDMI 2.1 omission is extremely baffling when the Xbox One X supports HDMI 2.1 & VRR TODAY. Sony & Microsoft even doubled down saying both their consoles will support HDMI 2.1. For home users that means they'll be supporting HDMI 2.1.

    It's just frustrating thinking about how that went over the heads of the decision makers associated with this monitor to omit that & HDR (everyone knows that HDR > resolution).

    Sigh. Beaten me to this comment and better. Reply

    Dell really needs to clarify whether this monitor is a DisplayHDR TrueBlack 400 monitor + has Displayport 1.4.

    Otherwise, I'm afraid this monitor is DOA. Why get this instead of a C9 w/ Dolby Vision *and* HDMI for $2500 less? Even more so when Realtek's Displayport 1.4 to HDMI 2.1 converter comes out.

    When I say C9, I'm referring to LG's 2019 HDMI 2.1 Dolby Vision HDMi 2.1 C9 TV w/ 4K@120hz. That TV will also be future proof with next gen consoles targeting 4K@120hz. It also uses the SAME panel.

    I think the researchers for this product really let this product down if the specs are without typos.

    - Dolby Vision & HDMI 2.1 should have been associated with this product at minimum using the same panel as the C9 essentially from LG display. Even if that raised this monitor at $5000, the existing BFGD are DOA'd by this product just as much as they were when LG C9

    - No Thunderbolt 3 port for modern laptops? WTF!

    I agree with everything you said except the TB part. TB is easily adaptable to other ports and not all laptops carry it. Reply

    TB3 monitors let you use the monitor like a desktop hub with a single cable - connecting a laptop to video, USB peripherals and sometimes even power. Reply

    I think most Ice Lake laptops will in fact have USB4 (meaning TB3). Reply

    Wait... Are you really planning to sit at arm's length from a 55" screen, to use it as your desktop monitor?!? Do you have any idea how freakishly large 55" actually is? Reply
