BenQ BL2581T review – very good picture and energy saving

The BenQ BL2581T belongs to the series of business monitors and was designed for use in the office. The 25- inch display dissolves with 1920 x 1200 pixels in 16:10 format, which makes it easier to view documents and work with multiple windows. A narrow frame, ergonomic functions and a brightness sensor are intended to provide additional benefits.

The ports are available with DisplayPort , HDMI, DVI and VGA all common variants. On audio and USB 3.0 ports must not be waived. Integrated speakers round off the package.

Of course, apart from the office functions, we are also examining the BenQ BL2581T’s all-rounder capabilities. With 5 ms, the reaction time is in a good range, if this is actually achieved in practice. We also check the color space coverage in the sRGB area and will also test what functions are available for video playback via PC and external source.

Detailed information on features and specifications can be found in the BenQ BL2581T datasheet.


The box of the BenQ BL2581T is relatively narrow and thus handy. It has two large styrofoam parts inside, which separate the accessories from the screen and guarantee safe transport.

The device is accompanied by a quick guide, a CD with a detailed manual and a power, USB and DisplayPort cable. For the connection variants via HDMI, DVI or VGA, an additional cable must be purchased accordingly.

Optics and mechanics

The structure of the monitor is very easy by hand. The base can be fixed without tools with a screw on the leg. This combination is then snapped into place on the back of the BenQ BL2581T. At the back of the unit there is a quick release, which is released by pressing the button on the back. The leg also has a practical carrying handle in the upper part and was optimally designed for the screen size. It keeps the screen stable in place without being clunky.

The front shows the almost frameless design of the BenQ BL2581T, which makes it look very modern. Otherwise, only the area below the manufacturer’s logo will be noticeable from the front, behind which there is a sensor for adjusting the brightness. The back has also been designed simply and therefore offers no significant details.

The panel edge is about 4 mm in operation. However, together with the small gap and the outer frame, the total width is still less than 1 cm, which preserves the slim character of the screen during operation.

The height can be adjusted continuously. The shot has been adjusted a bit more tightly, but still works well. In the lowest position, the distance from the desk to the lower monitor edge is only 4 cm, in the highest position 18 cm, resulting in a high adjustment latitude.

The inclination can be adjusted very comfortably by 5 degrees forward or 20 degrees backwards. The monitor remains in place despite the smooth adjustment at every desired position.

Rotation into pivot mode is possible as well as 45 degree turns in both directions. Thus, all conceivable adjustment options are available in this example, which he can achieve the best score in this area.

We were unable to detect large gaps or other negative properties. The monitor also looks modern and appealing when compared to the typical office screen. As a design highlight, we would not call the BenQ.


operating noise

During operation and also in standby mode noises or annoying whistling sounds could be detected even with an ear. The monitor behaved completely silently during operation.

However, especially the noise development can be subject to a certain series dispersion, which is why this assessment does not have to apply equally to all devices in a series.

power consumption

Manufacturer Measured
Operation maximum 55 W 21.7 W
140 cd / m² 11.4 W
Operation minimal 5.4 W
Energy saving mode (standby) <0.5W 0.1W
Off (Soft Off) <0.5W 0.1W
Switched off (power switch)

Based on the relatively small area of ​​the display, the maximum power consumption values ​​of the manufacturer are very high. As usual, we only measure the consumption with a connected PC via DisplayPort and were fortunately able to measure much lower values ​​there.

With a consumption of just 11.4 watts at 140 cd / m² (brightness set to 38), the device is one of the most economical models among our entire test candidates. The energy efficiency is very good 2.2 cd / W. The values ​​in standby and in the off state are also very good, so that the best grade can be achieved in this area.


Due to the recess in the leg, the connected cables can be routed neatly to the rear, as the cables are routed from below to the connections.

Audio, DisplayPort, HDMI, DVI, VGA and 4 x USB 3.0 ports of the BenQ BL2581T

The BenQ offers many connection options, but only one copy of each. Available are HDMI, DisplayPort, DVI and even VGA, which is still used in some offices and therefore makes sense. The four USB 3.0 ports can hardly be reached during operation, so they are not suitable for USB sticks. In addition, the device has no other lateral connections.


Below the front monitor frame are six buttons, five of which are available for controlling the OSD. On the frame itself, only very discreet points have been attached to find the individual keys better. In darkened rooms, however, the dots are barely recognizable. The OSD displays the current function via the buttons.

The pressure point of the keys is a bit slow. Not unpleasant, but this means that a very fast navigation through the menus is not possible. In addition, a mechanical noise is triggered each time the printer is pressed, giving the user direct feedback as to whether the device has registered the pressure. In addition, the keys have been made sufficiently large, and the distance between them is sufficient, so we never confused the keys during operation.

Each time you press one of the five buttons, the same little quick-start menu opens. The rightmost key closes the menu, and the adjacent key opens the main menu. The other three buttons can be assigned different setting options. Available are “Picture Mode”, “Low Blue Light”, “Display Mode”, “Brightness”, “Contrast”, “Auto Adjustment”, “Volume”, “Mute” and “Input Signal”. Therefore, there are exemplary possibilities for the individual needs of the respective users.

In the image settings, a lot of parameters can be set, but only in the user mode are fully selectable. In many modes, only the brightness, contrast and sharpness can be adjusted. An individually set film mode is therefore not possible.

With the advanced settings, depending on the connection type, even more areas are grayed out and only the picture and display modes can be selected. There are many predefined image modes available, but they can only be slightly customized.

In the last section you can set the general settings, including the shortcut keys and the display duration of the OSD. The second tab in the OSD is only relevant for a connection via VGA. Below the audio router, only the volume and type of signal can be set, so we have not depicted both sections.

Many options are available in the OSD, but they are greyed out in certain image modes or connection types, thus losing some customization options. In principle, however, the existing options are sufficient, especially taking into account the type of application as a office monitor.
