The inclusion of 12G-SDI positions this monitor at the intersection of professional broadcast-grade signal handling and compact field utility, offering real-time, uncompressed UHD video feeding directly from cameras. The display is factory-calibrated to Delta E < 2 and covers the sRGB and Rec.709 colour spaces, continuing ASUS’s focus on colour accuracy across its ProArt products.
Serial Digital Interface (SDI) is a standard for transmitting digital video signals over coaxial cable with very high reliability and low latency. Unlike consumer interfaces such as HDMI, SDI uses robust BNC connectors and supports long cable runs without signal degradation, making it preferable for multi-camera setups, live production trucks, and studio infrastructure. With the 12G-SDI variant, this interface can carry uncompressed 4K video at up to 60 Hz in a single cable run, reducing complexity and preserving image fidelity between camera and monitor or recorder.
Technical specifications
The PA16USV features a 15.6-inch 4K UHD (3840×2160) IPS panel with a pixel density of 282 ppi and typical peak brightness of 400 cd/m2. It supports HDR10, has a static contrast ratio of around 1200:1, and a response time rated at 5 ms. So far the specs according to the sheets.
Viewing angles are wide, at approximately 170° horizontally and vertically. Colour performance is a wideset coverage of 100 per cent sRGB and 100 per cent Rec.709. The panel’s anti-glare surface enhances usability in diverse lighting conditions. Refresh rate is capped at 60 Hz.
Connectivity and additional features
Connectivity on the PA16USV includes a 12G-SDI input for uncompressed 4K60 video feeds, a full-size HDMI 2.0 port, USB-C with DisplayPort Alt Mode, and a USB hub for peripherals. USB-C also provides limited power delivery for compatible host devices. Physical features include both a mini-stand and a kickstand for flexible positioning, VESA-compatible mounting patterns and optional tripod mount points suited to on-set rigging. Additional practical touches include Picture-in-Picture and Picture-by-Picture modes for multi-source monitoring, and QuickFit Plus on-screen overlays to assist framing and alignment.
Our review
The panel may even be redirected out of laptop production lines, but this 16” monitor aims at the needs of video professionals in cramped ‘video village’ situations. We don’t expect many readers to consider UHD resolution on such a small screen over a good 27” one for their daily work on a computer. But it should be good enough to spot focusing issues where size and portability are of primary importance. Asus also claims professional-grade colours, so we had a closer look – and found a serious flaw, but not regarding colours.
True colours?
Like others from the ProArt line, the monitor comes with an individual calibration sheet, measured by a Konica Minolta CA-310. While that is a highly respected measuring device in the industry, it has been discontinued. So, forgive us if we cross-check with a humble Spyder Pro and a X-rite, as recently reviewed here. The spec sheet has obviously been measured for a gamma of 2,2, showing a reasonably close value of 2,18. While this is used a lot for social media, it’s not the correct gamma for video, which is 2,4 according to Rec.709 BT.1886. This alone is a source of endless discussions and even more frustration. Another source of ambiguity is the correct brightness, which is not specified in the spec sheet. It should be 100 nit according to TV standards, but some may prefer 120 nit these days.
The PA16USV is offering several fixed gamma values in its menu, including 2,2, 2,4 and even 2,6 as defined by DCI for cinema. We measured it with the preset of gamma 2,4 and adjusted the brightness to 100 nit according to our probe. With these settings we got 99% of Rec. 709 and sRGB color space, which are the same anyway, and the difference to 100% would not be seen by any pair of human eyes. The uncalibrated value for gamma was a bit too high at 2,46, which should be visible for a trained person. The white point was slightly off with the internal preset for Rec.709, while the preset of 200 was more like 108 nit. You’ll need to increase it to 216 as a starting point if you want to calibrate for 120 nit.
The results after calibration proved that even a screen with factory calibration can be slightly improved, but colours were already excellent out of the box. It may need calibration after being in use for a few months; nevertheless, this is due to normal ageing of electronic components. Our verification by DisplayCal with the i1 DisplayPro device gave us a near-perfect white point at 6.548K, pretty good blacks for a TFT at 0,07 nit and an average Delta E of 0,75 with a maximum around 1,5. Very few patches were above 1 at all, which is still well below perceptible deviation. The contrast ratio of 1.300:1 is really good for TFT technology and even a bit higher than the manual claims.
But can this handle HDR?
Asus is claiming a maximum of 400 nit, but the Spyder Pro measured only 350 at that point. Even if those ubiquitous three letters are listed with the specs, they are not even claiming that minimal standard of VESA 400. So, we are still far from any serious HDR monitoring, and this doesn’t mean much more than: “Yes, this screen understands HDR and will not be completely off.” The PA16USV is even offering three HDR modes in its menu for PQ Optimized, PQ Clip, and PQ Basic. But being just a TFT monitor without any local dimming, it can’t replace this ProArt PA32UCDM with OLED and 1.000 nit peak. That one is a true low-cost HDR screen with 99% DCI-P3 coverage, true blacks and 10 bit. On the other hand, that large monitor doesn’t even have an SDI input and it has a glossy screen.
Or even DCI?
Our candidate is not glossy and has a 12G SDI input, but neither has DCI 4K. The ProArt 16 USV offers a preset for DCI-P3, with gamma at 2,6 and the slightly different white point of 6.300K, called P3 Theater here. The preset also sets brightness to 48 nit. In this case we measured a gamma of 2,61, pretty good blacks at 0,02 and 0,3 deviation of the white point. It can also be switched to 6.500K and a gamma of 2.2, which is a popular version on the web, often called Display P3 (for further explanations, see here). This preset showed slightly higher blacks at 0,04, gamma too high again at 2,26 and white 0,3 off – nothing you can’t overcome with minor calibration. Unfortunately, in both cases, the colour space is limited to 76% of P3, which resulted in pretty strong deviations for several colour patches well beyond that imperceptible Delta E under 2 for Rec. 709.
Mechanics
Parts of the packaging double as a pretty good shade for location work, a clever approach to limit packaging and what’s going to the bin. Mounting is flexible with 1/4” screw holes at the top and the bottom, provisions for a VESA mount, and a flap at the back to set the monitor on a flat surface at an angle.
The small plastic feet, optionally mounted to the bottom, are a bit flimsy and may not last too long. The frame is of relatively solid plastic and keeps the weight down to 1,3 kg, but you may want to keep it in a sturdy flight case when travelling.
Electronics
Sources can come through the upper USB-C port, which is compatible with DisplayPort 1.2 or DP 1.4, through HDMI or SDI. The input range is switchable between full range, 16-235, or 16-254, so sources with ‘superwhites’ will be digested too. When connected to a camera by SDI we didn’t notice any latency worth mentioning. Both USB-C ports can also deliver power to external devices, 5V/1,5A from the upper one and twice as much on the one below. On the left side, there is a USB-C port just for power input from the included power adapter. The device itself consumes less than 15 W, but it requires 15 to 20 V, so it can be powered by a laptop or charger, but not by most power banks, which typically supply only up to 12 V. A single USB-A port on the left is for service use only. Two keys can be defined by the user for quick access to regularly used settings. The multilingual menu is easy to understand for those familiar with ‘video lingo’, but switching between modes or signals needs quite some patience. There are no scopes at all, no focus peaking, nor audio, but safe areas, centre markers, and rulers.
One serious issue
While the manual says it accepts 24, 30, or 60 Hz, we didn’t notice any tearing when supplying 25 or 50 Hz, and these frame rates were correctly identified under “Information” in the menu. Unfortunately, the monitor does not correctly identify those pesky fractional frame rates made for the colourful NTSC world. When fed with 23,98 fps it simply says it’s 24, 29,97 is seen as 30, and 59,94 as 60. While you’ll see a picture, such misleading information at the top of the menu, or in the submenu with all the information about your signal, can lead to heated discussions between the DoP and the DIT. Or even worse, since many hybrid cameras by Sony (for example, there are others too) do just the same: you choose 24 or 30 fps in their menu, and they deliver the slightly slower rate without telling you. Now, imagine you are shooting multicam for a live event, let’s say an opera or a concert, and not all your cameras are behaving like this. Ouch!
Commentary
The Asus PA16USV is a good monitor for SDR with SDI 12G, precise colours out of the box and good contrast. But it’s in dire need of a firmware update to show correct frame rates for all varieties of incoming signals. Until that happens, use it with caution. And while they are at it, maybe Asus’ developers can make recognition of the incoming signals a bit faster. Other monitors do better in that respect.
