ASUS PQ22UC REVIEW: THE FIRST PORTABLE 4K OLED MONITOR

Having a small size 4K OLED monitor, portable moreover, is a dream that has become a reality thanks to Asus. OLED screens under 55 "inches have been talked about for some years already, the first AMOLED prototypes were seen in 2016 at the CHTF (China Hi-Tech Fair) in Shenzhen, a well-known Chinese fair where the 31 "inches of which, however, nothing more has been heard.

Before that, 31 "inch OLEDs were announced by Samsung in 2007, during the CES in Las Vegas, but even these never saw the light. Asus thought about making the first portable OLED in the world with the PQ22UC .

Size matters

In the OLED field only recently has fallen below 55 "inches, with a first proposal of 48" inches, but reaching such a small size, as in the case of the Asus PQ22UC, almost 22 "inches (21.6"), has the flavor of the record precisely because the screen becomes portable. The PQ22UC is a display that goes beyond HDR10, however, still not widespread on screens other than commercial TVs, where in this case Dolby Vision is also added in addition to HLG , in all with a 10-bit panel and resolution UHD, which for completeness would only lack HDR10 +.

Accessories yes, but for a laptop

The PQ22UC is equipped with an anti-reflective treatment and offers a space-saving level reduced to the minimum terms (510 mm x 313 mm x 8.5 mm - W x H x D), with a very low weight of 1.5 kg, easily transportable thanks to the practical bag included in the package. The accessories include a stand with a metal base on which the screen rests while remaining anchored to a protruding plastic element, as well as a more classic protective case which, as in the case of a tablet, allows the screen to be tilted. No VESA attachment, flexibility and adaptability remain confined to the portable field: if some accessory manufacturer does not think about providing a valid alternative with a different support base and stand, height adjustment remains one of the sore points.

Who is it for?

The pixel density is excellent, of 204 ppi, thus competing with state of the art monitors such as Apple's Retina for which the perception of pixels should be very difficult if not impossible to notice. The exploitation in the photo / video field is also ideal for this, the PQ22UC is a monitor dedicated to professionals. The screen frame stands out but at these levels it would have been unthinkable to offer a further reduction of the same. This allows a firm grip in motion, but also to interact with the OSD. Below is the moment of the test with the 4K version of "Profondo Rosso" by Dario Argento (copyright RTI)

Few connections

It was reasonable to expect an input dedicated to the power supply, instead there are three terminals: two USB-C (with Display Port 1.2 mode) and one Micro HDMI 2.0. One of the two USB-Cs is necessarily used to power the screen, while the other terminal remains available for different uses. Beware, however, that the free USB-C port cannot be used to connect a possible docking station since the aforementioned is not powered. The control button are all locate on the left edge: one for ignition / stand-by and two below for navigation within the menus. The presets as well as the settings are quite immediate and intuitive and there should be no difficulty in choosing the best operating condition.

Stunning video quality

The response time of 0.1 ms would appeal to gamers but, also remembering the retention issue of OLEDs, the fact remains that here we do not go beyond the 60 Hz refresh rate. Furthermore, the PQ22UC is not FreeSync compatible, which would have offered a more efficient refresh rate and averted the risk of tearing. The infinite contrast, blacks as per the OLED tradition, the possibility of viewing native UHD material, even Dolby Vision, are a magnificent reality even with such a small screen. The same can be said for the factory pre-calibration, where the DeltaE at REC.709 exceeds even if slightly the value 2, something more measured in DCI-P3, but these are deviations that theoretically do not require manual intervention (in the images the detection DCI-P3 and under REC.709).

Professional services

This particular 21.6 "inch screen has a very high potential as it is widely portable, for photo retouching or for video processing where color fidelity must be the top priority. DCI-P3 coverage is around 99%, sRGB 100%, with an average brightness of 140 nits and HDR peaks even over 330 nits. Is the show guaranteed to ... see an entire movie in UHD or play video games? The screen is too small to consider for such use. In the professional environment instead the PQ22UC finds its natural place, after all, those wishing to move outdoors with a display capable of performance even higher than that of an OLED TV at the moment would have no other choice.
