Iiyama’s ProLite XB2779QQS: a 27-inch 5K IPS Monitor for $900

Stefan Mileschin · 28th March 2018, 11:34

Iiyama has started selling its new 5K IPS monitor. The ProLite XB2779QQS boasts with a 5120x2880 resolution and is available at a price point of around $900. The catch? It has a rather thin feature set and it can only display 5K resolution over a DisplayPort 1.4 interface.

The Iiyama ProLite XB2779QQS monitor relies on a 27-inch 6-bit + A-FRC IPS panel featuring a 5120×2880 resolution, a 440 nits typical brightness, a 1200:1 contrast ratio, a 4 ms response time, a 60 Hz refresh rate, and 178°/178° viewing angles. The LCD is equipped with a LED backlighting featuring a flicker-free technology, which is common on many displays these days. In addition, the screen is covered with glass from edge to edge, that can produce a glare.

The ProLite XB2779QQS is among the first 5K monitors to use a 6-bit + A-FRC IPS panel - its predecessors aimed at professionals were based either on 8-bit + A-FRC, or even 10-bit panels. A 6-bit + A-FRC panel is considerably cheaper than the aforementioned types of display modules, but at a cost of color accuracy. Iiyama says that its 6-bit + A-FRC IPS panel can display 16.7 million colors (vs. 1.07 billion on professional LCDs), but it never mentions color spaces that the monitor supports internally and how well it covers them. It is completely reasonable to expect the XB2779QQS-S1 to support some form of sRGB, but it is unlikely that the display can handle a high percentage of DCI-P3.

The new ProLite XB2779QQS display requires a DisplayPort 1.4 connection to support a 5K resolution at 60 Hz. By contrast, existing 5K monitors use two DisplayPort 1.2 streams (either via two DP cables, or one TB3 wire in case of the LG UltraFine 5K). In addition to DisplayPort 1.4 inputs, the ProLite XB2779QQS also has HDMI 2.0 connectors, but the monitor can only support a 3840×2160 resolution at 60 Hz over HDMI.

Like many prosumer displays, the ProLite XB2779QQS supports height, swivel, and tilt adjustments. In addition, the monitor features two 2.5 W speakers and a headphone connector for added comfort.
