4K at 120 Hz with Deep Blacks



Today, Dell officially unveiled its new OLED gaming flagship Alienware 55 monitor at Gamescom. First introduced at the Computex, the display uses a 4K OLED panel with a refresh rate of 120 Hz, making it one of the fastest 4K monitors on the market. The Alienware 55 supports AMD FreeSync variable frame rate technology, which differentiates the monitor from OLED UHDTVs, but not in the HDR implementation.

The Alienware 55 is based on a 55-inch OLED panel with a resolution of 3840 x 2160 (400) nits peak brightness, a contrast ratio of 130,000: 1, a gray-to-gray response time of 0.5 and a maximum refresh rate of 120 Hz. The screen can reproduce 98.5% of the DCI-P3 color space, which is comparable to the accuracy of professional LCD displays. The monitor also has a 2H hardness antireflective coating for added clarity when used on bright days.

The main feature of the Alienware 55 is a combination of its technologies and its size. OLED computer screens are generally rare and this is the industry's first OLED monitor for gamers. However, the product is not without its limitations: despite the use of OLED technology, it is not an HDR monitor. In fact, Dell says nothing about Alienware's 55-incher that supports HDR10 or Dolby Vision transports. Regardless of the panel's function, the monitor itself does not seem to support HDR input formats.

The Alienware 55 has three HDMI 2.0 inputs and a DisplayPort 1.4 connector , the latter being the second weirdness in today's announcement. At full 4: 4: 4 / RGB color, DisplayPort 1.2 is limited to 60 Hz. You need DisplayPort 1.4 for 4K @ 120Hz with 8bpc color. So for what Dell does, there is a flaw somewhere in the specifications or compromises. Either DisplayPort 1.2 is right and they do something like 4: 2: 2 choma subsampling to get 120 Hz running, or this is not a real 120 Hz monitor at all – and instead a 60 Hz monitor with black frame insertion , a common tactic for TVs. We are not sure what these are at the moment, and we contacted Dell to clarify this.

Update : Dell has contacted us and confirmed that this is the original datasheet was wrong, and that the monitor comes with DisplayPort 1.4 instead of 1.2. The display actually has enough bandwidth for 4K @ 120Hz with 8bpc color.

In the future, the display will feature a four-port USB 3.1 Gen 1 hub, a headphone output, and an S / PDIF output. When it comes to audio, the display has two 14 W speakers, which were developed together with Wave Maxx Audio.

Like other large displays, the Alienware 55 has a remote control that allows you to adjust the brightness, control the sound, and perform other functions.

Dell will begin selling the Alienware 55 display as of September 30 for $ 3,999.99.
