Our review


The Asus PA32UC is the successor to the Asus ProArt PA328Q that we tested in 2015. It still carries a 32-inch (82 cm) IPS panel displaying an Ultra HD definition of 3,840 x 2,160 px, but swaps the system Edge Led for a Full Led backlight system made up of 384 zones and now displays HDR compatibility, whether on PC or console. The manufacturer announces a maximum brightness of 1000 cd / m² in HDR, a contrast of 1000: 1, viewing angles of 178 ° / 178 °, a response time of 5 ms, 85% coverage of the Rec2020 color space, 99.9% of Adobe RGB, 95% of DCI-P3 and 100% of sRGB. Even if it is not intended for gaming, this monitor is still compatible with FreeSync technology between 40 and 60 Hz.

The Asus ProArt PA32UC is sold at the recommended price of € 2,300, but it is unfortunately regularly sold more expensive. Its main competitor is the Dell UltraSharp UP2718Q, a 27-inch Ultra HD model compatible with HDR.



Very well finished, this monitor targets a very high-end segment that does not forgive. The screen edges are quite thin, but the foot is imposing.

[/ link] Adjusting the tilt and height as well as switching to portrait mode.

In terms of adjustment, this monitor allows the adjustment of the height on 13 cm, the tilt from -5 to + 23 °, the rotation on +/- 60 ° and a pivot allowing to switch to portrait mode. It is also VESA 100 x 100 mm compatible for mounting an articulated arm. All adjustments are made smoothly, without any extraneous noise. A guarantee of quality.

The rear is very sleek.

The back of the monitor is classic and sleek as possible. The ribbed plastic is of good quality. The connections are hidden by a plastic cover and a sort of clamp allows the cables to be grouped at the base of the foot. The power supply is integrated, which saves space under the desk.

The connectivity is quite rich. This monitor offers a DisplayPort 1.2 input, four HDMI 2.0b inputs, two Thunderbolt 3 ports, one of which supports laptop load up to 60 W, two USB 3.0 ports and one USB-C port. There is also a headphone output that allows you to recover the sound sent to the monitor via HDMI or DisplayPort. It also has two 3 watt speakers of acceptable quality.

To navigate the OSD menus, Asus always uses its clickable joystick. We can thus go from one menu to another very quickly without having to juggle between buttons. It is the most efficient system to date for quickly adjusting a monitor. The other buttons give direct access to the brightness, source, etc. adjustment. The OSD offers full settings with the choice of preset mode, including two HDR modes and two customizable modes. It is also possible to adjust the blue light filter to four levels and change the settings further.

On our 140 x 60 cm desk, the 32-inch screen finally occupies a reasonable space. The foot depth (23 cm) remains reasonable, especially compared to the models for players (Alienware AW3418DW, for example).

Ultra HD definition on a 32 inch diagonal is perfect for working with images. It must be said that with a resolution of 138 pixels per inch, the rendering is really excellent. On the other hand, it will not follow everyone. Some elements of the interface are too small in native definition and it is necessary to use the integrated scaling in Windows to find a certain comfort of use. For general public use, we always prefer the Quad HD definition on a 32 inch diagonal which allows a more versatile use (game, film, etc.).

By lowering the brightness to 33 to obtain a white at 150 cd / m², the Asus ProArt PA32UC consumes 49 W, or a relative consumption of 174 W / m², much higher than the average of the monitors tested (100 W / m²). At minimum brightness (23 cd / m²), the monitor consumes 24 watts. At the maximum (237 cd / m² in SDR), consumption increases to 60 W.


Colors and contrast

Default: average gray temperature: 7,470 K.

Default: gamma curve at 2.2.

Default: Delta E average at 4.6.

The monitor's factory settings leave something to be desired. The fault with the mode chosen by default (Standard) which is not the best calibrated. The temperature curve is stable, but the average measured at 7,470 K is a little far from the 6,500 K reference. The gamma settles on the reference value (average of 2.2) and, above all, the curve is almost smooth over the entire spectrum. The main problem with this Standard mode comes from color reproduction since the delta E is measured at 4.6, far from the delta E of 3, a threshold below which the human eye no longer perceives the difference between the colors requested and the colors displayed. Some colors like green or cyan even have their Delta E exceed 8.

Manual adjustment: average gray temperature: 7,420 K.

Manual adjustment: gamma curve at 2.2.

Manual adjustment: delta E medium to 1.5.

Fortunately, the sRGB mode provides almost perfect picture adjustment. The temperature and gamma curves are identical - the temperature is still slightly too high (7 420 K), but the colors are finally perfect, with an average Delta E of 1.5. Only blue approaches delta E of 3. Unfortunately, with the sRGB mode, it is impossible to manually improve the brightness or the color temperature without negative impact on the other settings.

Calibrated: average gray temperature: 6,730 K.

Calibrated: gamma curve at 2.2.

Calibrated: average delta E at 1.2.

The use of the X-Rite i1DisplayPromonitor calibration probe delivered with the Asus ProArt PA32UC allows to reduce the temperature of the sRGB mode to 6,730 K, and therefore very close to the 6,500 K reference. It also smooths the gamma curve perfectly. Color rendering is also better, with an average delta E at 1.2. You can download this color profile by following this link.

As usual, IPS technology limits the contrast to around 1,000: 1. Here we measured a contrast ratio of 1,150: 1. This is correct for a monitor intended for photo editing, but in absolute terms, it is less good than monitors equipped with a VA panel, displaying a contrast greater than 4,000: 1 (Textorm TX32, Philips BDM4037UW or still AOC Q3279VWF).

The Asus ProArt PA32UC has two HDR modes that manage Display Tone Mapping differently. HDR1 mode offers a balanced rendering which allows - despite the low contrast of the panel - to preserve details in dark areas. HDR2 mode emphasizes brightness, with a light peak recorded at 1,112 cd / m². With the latter mode, the blacks are less deep, but the luminous objects seem to shine. Overall, the HDR rendering is quite convincing, but the monitor is clearly handicapped by its lack of native contrast and poor management of the local dimming.

The average difference in lighting uniformity is 10% across the entire slab. An absolute good figure for a 32-inch monitor, but average for a monitor with a Full Led backlight supposed to be flawless on this precise point. We did not find any light leaks in the corners or clouding on our test model. If the 384-zone backlighting system makes it possible to increase or decrease the brightness of certain zones, the local dimming is fairly poorly managed and results in a fairly annoying blooming phenomenon. Like Dell, Asus is a far cry from the quality of processing that TV manufacturers offer - which limit blooming by using specific algorithms to compensate for light leaks. Problem, if used on PC, this type of processing would increase the delay in the display.

Colors and contrast


The Asus PA32UC does not use Pulse Width Modulation (PWM) to adjust the brightness. It therefore does not flicker and does not cause headaches for the most sensitive people. It also offers a filter to limit blue light.

This monitor manages FreeSync between 40 and 60 Hz and therefore works optimally when the graphics card sends between 40 and 60 images per second; a fairly low range which is still suitable for Ultra HD definition which is very demanding in terms of graphics power. In the operating range, fluidity is at the rendezvous and the image does not suffer from tearing problems or jerks (micro-stuttering). Even if this monitor is not intended for players, it is still a little more.

We measured the remanence time at 10 ms with the overdrive (called "TraceFree" at Asus) set to 60. This value allows to limit the ghosting. Beyond that, with the values 80 and 100, a fairly annoying reverse ghosting effect appears. Finally, we measured the delay in the display (input lag) at 10.8 ms (60 Hz). There is thus no offset between the source and the display on the monitor.



The ultimate monitor for image professionals, the Asus ProArt PA32UC is almost flawless. The ergonomics are flawless, the complete connectivity and the quality image. Too bad this monitor is not perfectly calibrated at the factory. Fortunately, the supplied X-Rite i1Display Pro calibration probe allows you to perfectly adjust the display and recalibrate it regularly. HDR support with a light peak at 1000 cd / m² is a plus, but the low contrast limits the final rendering.
