The design of the monitor is made in the recognizable style of Apple all-in-one PCs.

The monitor panels are made of matte silver plastic. The aluminum alloy stand has the same matte silver finish after anodizing. The outer surface of the screen is black, semi-matte and hard, giving the impression of a monolithic surface. However, the screen is actually limited by a narrow frame at the bottom and thin bezels on the top and sides. When displaying an image on the screen, you will notice that there are small margins between the outer edges of the screen and the display area itself: about 6 mm to the border at the top and sides, and about 1.5 mm to the frame at the bottom.

The central part of the front panel is decorated with the manufacturer's logo, painted in modest gray paint.

On the back panel, in a shallow recess of the case, there is a convenient 5-way joystick that allows you to move in four directions and press inward to select options. This control can be activated either from the right or from the bottom. The second access option is useful if the monitors are installed very close to each other.

The power connector and interface connectors are located in the same niche at the back and are oriented towards the rear.

You will have to connect the cables to the monitor through the cutout in the stand. In the case of large cable lugs, this is not very convenient.

There are ventilation grilles located on the top and bottom edges, as well as on the rear side of the housing outlet. Behind the grilles on the bottom edge are two built-in speakers. There is also a Kensington lock slot on the bottom edge.

The base of the stand has a large area, ensuring the stability of the monitor. On the upper surface of the base you can place the edge of the keyboard or various small items. Rubber pads on the underside of the base prevent scratches on the desk surface and prevent the monitor from sliding on smooth surfaces.

The hinge on the stand allows you to tilt the screen unit slightly forward from the vertical position and tilt it further back.

The screen unit is installed at the optimal height, providing a comfortable workspace for working behind a monitor located at a standard office desk height in a vertical position.

Please note that our monitor came in pre-sale packaging and we do not have a photo of the original packaging.


The monitor is equipped with two full-size digital inputs — DisplayPort and HDMI — complemented by a USB-C input. The input selection is made in the main settings menu or in the quick access menu. There is a switchable function of automatic signal search at the inputs.

Digital audio signals from DisplayPort, HDMI and USB-C inputs are sent through digital-to-analog conversion to the built-in speakers and 3.5mm mini-jack. This allows you to connect an external speaker system or headphones. There is enough headphone power to provide moderate volume in 32 ohm headphones with a sensitivity of 92 dB. The sound quality is fairly clear, with minimal background noise, although the bass may be lacking.

The built-in speakers sound according to their size and the constraints of the acoustic environment. They are able to transmit system signals at a high enough level for comfortable use, although there is no reproduction of low frequencies due to cabinet resonances. The stereo effect is weak, and at high volumes the sound is distorted.

The USB-C port supports power transfer with a stated power of up to 65 W. Testing the monitor via USB-C with a Huawei MateBook X Pro (MACH-W19) laptop showed good results: the laptop charges successfully (the monitor consumes up to 65 W), and the image is displayed on the monitor (maximum resolution 3840x2160 pixels at 60 Hz).

The monitor comes with a good quality HDMI cable, although it may not be very long.

External power supply. This has both its advantages (easy replacement in case of failure) and disadvantages (it can get in the way).

Menu, control, localization, additional functions and included software

No power indicator was detected on the monitor. There is something resembling an indicator at the bottom end, but it does not light up in any of the operating modes. To turn on the monitor, use the joystick, and to turn it off, hold the joystick down for a certain time.

When the monitor is on and there is no menu on the screen, when you move the joystick up, down, right or left, a slider or short menu appears on the screen with four settings: countdown timer, crosshair selection, input selection and image mode.

When you press the joystick, the settings menu appears on the screen. The menu is a bit small (for scale: the white field is the entire display area):

Navigating through the menu is very convenient, since everything is done only with the joystick, you don’t need to move your finger on the buttons, and the number of necessary actions is reasonably reduced, and the lists are looped. When adjusting the image, the menu remains on the screen — this somewhat interferes with the assessment of the changes being made.

If necessary, you can set the transparency level of the menu background, select a timeout for automatically exiting the menu, and move the menu horizontally and vertically. There is a Russian version of the on-screen menu.

The quality of translation into Russian is acceptable. The user manual is not very informative; it can be found as a PDF file on the Digma website.


There are few settings that change the brightness and color balance.

There is a set of preset fixed values for a number of settings in the form of several factory profiles. In the Standard profile you can change all settings.

Several geometric transformation modes will help you choose the best option in the case of a source with a resolution and aspect ratio that is not native to the monitor.

Using a professional Nvidia Quadro K600 graphics card and NEC Display Solutions 10 bit Color Depth Demo, we conducted testing that showed that the monitor supports 10 bits per color mode when using DisplayPort, but actually displays the image on the screen in 8 bits per color mode. This test is performed to determine the ability to display 10-bit color images in programs that use OpenGL, such as Adobe Photoshop and Adobe Premier Pro, when using professional graphics cards such as Nvidia Quadro, AMD FirePro or AMD Radeon Pro.

The monitor also supports AMD FreeSync technology (in VRR and Adaptive-Sync modes) via DisplayPort and HDMI inputs. This ensures images move smoothly without tearing. With Nvidia graphics cards, the monitor supports G-Sync Compatible mode via the DisplayPort port, which also ensures smooth, tear-free images. The USB-C input has not been tested for FreeSync and G-Sync Compatible compatibility.

Connecting to a computer via DisplayPort allows you to work with a resolution of up to 5120x2880 pixels at 60 Hz frame rate with a signal of 8 bits per color. When the frequency is reduced to 30 Hz, resolutions of up to 5120x2880 pixels with a 10-bit per color signal are supported. Via HDMI, resolutions of up to 5120x2880 pixels at 30 Hz frame rate with an 8-bit per color signal are supported. HDR is supported in these modes.

To check whether the device meets the VESA certification criteria, we used the official DisplayHDR test tool. The test results confirmed that the monitor displays 10-bit images, providing high brightness and color quality close to DisplayHDR 400 criteria.

LCD matrix testing

Microphotographs of the matrix

The image of the pixel structure is blurry due to the matte surface, but the structure characteristic of IPS can be recognized (black dots are dust on the camera matrix):

Focusing on the screen surface revealed randomly located surface microdefects responsible for the matte properties:

The grain of these defects is several times smaller than the size of subpixels (the scale of these two photographs is the same), therefore focusing on microdefects and the “jumping” of focus across subpixels when changing the viewing angle are weakly expressed, because of this there is no “crystalline” effect, but a change in brightness and there are colors within the pixels.

Color rendering quality assessment

To assess the pattern of brightness growth on the gray scale, we measured the brightness of 256 shades of gray (from 0, 0, 0 to 255, 255, 255). The graph below shows the increase (not absolute value!) in brightness between adjacent halftones:

The increase in brightness is very uniform. Moreover, each subsequent shade is significantly brighter than the previous one, even in the darkest area:

The approximation of the resulting gamma curve gave a value of 2.25, which is quite a bit higher than the standard value of 2.2, while the real gamma curve deviates little from the approximating power function:

To assess the quality of color rendering, an i1Pro 2 spectrophotometer and the Argyll CMS software package (1.5.0) were used.

The original color gamut is noticeably wider than sRGB and approaches the Adobe RGB gamut:

Below is the spectrum for the white field (white line), superimposed on the spectra of the red, green and blue fields (lines of the corresponding colors) in the case of the original color gamut:

It can be assumed that backlight LEDs use a blue emitter and green and red phosphors, while the red phosphor (and maybe green) uses so-called quantum dots. Good component separation allows for a wider color gamut.

There is a profile with a color gamut close to sRGB:

In this case, the coverage is reduced due to cross-mixing of components:

Unfortunately, after selecting this profile, we discovered that color balance settings were not available. However, in mature operating systems such as Windows and professional imaging software, it is often possible to achieve the desired color correction using a color management system (CMS). For example, you can use the color profile created in our tests using DisplayCAL software for this purpose, as long as the profile does not require correction.

Selecting a custom profile (Standard mode) to adjust color balance ensures maximum brightness and contrast while maintaining acceptable image quality. The color temperature in this mode is significantly higher than the standard 6500 K, but the deviation from the blackbody spectrum (ΔE parameter) remains below 10 units, which is acceptable for the average user. Despite this, both parameters remain stable across different parts of the gray scale, improving the visual perception of color balance.

The sRGB profile also provides near-standard 6500K color temperature and ΔE below 10 units, making it suitable for viewing regular images without the use of a color management system. The graphs below show the color temperature at different parts of the gray scale and ΔE for the Standard and sRGB profiles.

Measuring black and white uniformity, brightness and power consumption

Brightness measurements were taken at 25 screen points located in increments of 1/6 of the screen width and height (screen borders not included, monitor settings set to values ​​that provide maximum brightness and contrast). Contrast was calculated as the ratio of the brightness of the fields at the measured points.

ParameterAverageDeviation from the average
min., %max., %
Black field brightness0.27 cd/m²−1133
White field brightness480 cd/m²−5.06.2

If you step back from the edges, the uniformity of white is very good, but the uniformity of black, and as a result, the contrast, is worse. The contrast for this type of matrix, by modern standards, is significantly higher than typical. It is visually clear that the black field is mainly slightly overexposed closer to the edges. The photo below demonstrates this:

However, the nature and level of black light can vary significantly for each device.

When the DCR (Dynamic Contrast Ratio) mode with dynamic brightness control is activated, the contrast formally increases, but does not reach infinity, since even on a black field throughout the entire screen, the backlight is not completely turned off. Below is a graph showing how brightness changes (on the vertical axis) when moving from a black field (after five seconds of output) to white with dynamic brightness adjustment on and off.

It can be seen that in dynamic mode the backlight brightness increases very slowly. There is little practical benefit from this function.

Brightness of the white field in the center of the screen and power consumption from the network (other settings are set to values ​​that provide maximum image brightness, refresh rate 60 Hz ):

Setting value BrightnessBrightness, cd/m²Electricity consumption, W

When the monitor is in standby mode, its power consumption is about 0.3 W, and in the conditionally off state it is about 0.2 W.

Changing the screen brightness is directly related to the brightness of the backlight, while maintaining high image quality (contrast and the number of distinguishable shades are preserved). A wide range of brightness adjustments allows you to comfortably use the monitor for gaming, working and watching movies in both well-lit and dark rooms. At any brightness level, there is no significant backlight modulation, which eliminates noticeable screen flickering. It is important to note that there is also no pulse width modulation (PWM). To demonstrate the absence of PWM, graphs are provided showing the dependence of brightness (on the vertical axis) on time (on the horizontal axis) at various brightness settings.

Determining response time and output latency

Measuring response time and output latency clearly demonstrates that the Overclock setting does not affect response time. The assumed matrix overclocking control does not affect the response time. The response time associated with the transition between black and white and back is 16 ms (7 ms on + 9 ms off). In the case of transitions between different shades of gray, the average time is 28 ms. The matrix has an average response speed without using any overclocking.

When measuring the total output latency from switching the video buffer page to displaying the image on the screen, the output latency at 60 Hz was found to be 13 ms. This low latency is almost unnoticeable when using a computer.

Measuring viewing angles

To find out how screen brightness changes when deviated from perpendicular to the screen, we took a series of measurements of black, white and grayscale brightness at the center of the screen over a wide range of angles, deviating the sensor axis from approximately perpendicular to the screen in vertical, horizontal and diagonal (angle for 16:9 format) directions.

Reducing brightness by 50% of maximum value:


Measurements indicate an unusual characteristic of brightness reduction across viewing angles for the IPS matrix type. Viewing angles are not wide, which is not typical for an IPS matrix. When deviated at an angle to the diagonal of the screen, the brightness of the black field begins to increase sharply already at 20°-30° deviation from the perpendicular. If you are close to the screen, the black field in the corners will be noticeably lighter than in the center (taking on a slightly reddish tint). Contrast over a range of angles of ±82° when tilted diagonally approaches 10:1, but does not fall below.

To more accurately quantify changes in color rendering, colorimetric measurements were carried out. These included white, gray (127, 127, 127), red, green, blue, and light red, light green, and light blue areas across the entire screen at angles from 0° (perpendicular sensor position) to 80° s in 5° increments. The obtained intensity values were recalculated into ΔE relative to the measurement of each field at a perpendicular position of the sensor relative to the screen. The results obtained are presented below:

The reference point for assessing viewing angles can be taken to be a deviation of 45°, which can be significant when the image on the screen is viewed by two people at the same time. To maintain the correct transmission of the color range, the criterion can be a ΔE value not exceeding 3. Good stability of color characteristics is one of the main advantages of an IPS matrix.


The Digma Pro Art M IPS 5K monitor is a screen with a minimalist and distinctive design, equipped with a simple stand design without height adjustment. One of its key features is its high 5K resolution. This monitor is generally suitable for a wide range of tasks, including standard office work and CAD/CAM use. In addition, its use is possible in areas where high color accuracy is required, both across the entire screen area and when viewed from different angles. For example, for processing graphic images and editing video content. From time to time, between tasks, it can also be used for gaming, especially if the 60Hz refresh rate is sufficient.
