We have a new business monitor for review called Acer B248Y bemiqprcuzx. This is video conferencing monitor was recently released by the Taiwanese company and is specifically aimed at commercial customers. The device features a large 23.8-inch IPS panel with Full HD resolution (1920 x 1080 pixels) in 16:9 format. The refresh rate is up to 75Hz, the contrast ratio should be 1000:1, and the response time is 4 ms.
The ZeroFrame design ensures a nearly frameless screen and should ensure excellent image quality with 72% NTSC and color accuracy of Delta E <2. While the supporting leg mechanically ensures ergonomics, the Acer Vision Care 3.0 also supports it electronically. Ambient exposure is detected by a sensor and the monitor’s brightness is adjusted accordingly.
In terms of equipment, the Acer B248Y goes far beyond a standard monitor. In addition to a docking station with USB-C and RJ-45 LAN, the LCD monitor offers a webcam integrated into the upper edge of the housing for convenient conferences. Multiple screens can be connected in series using the daisy chain function. Image blockage is minimal thanks to the ZeroFrame design.
The base plate is mainly made of plastic and has small metalcore. Rubber studs ensure a secure stand. However, the metal plate finish doesn’t look particularly elegant. The protruding plastic cover is also sharp. So lifting equipment for transportation is not particularly pleasant.
The ergonomic functions of the device are certainly worthy of praise. The mechanism can be operated without much effort and offers everything your heart desires: 15cm height adjustment, 60° lateral rotation in both directions, and tilt setting from -5° to +35°. It is also possible to do panning in portrait format.
Only the DisplayPort cable is missing within the scope of delivery to fully equip the signal input. In addition to the mandatory power cable, 1 x HDMI, 1 x USB-C, and a cable for USB Hub Type B are included. A printed user guide is included. With PnP monitors, driver installation is usually not required, but it is good if the display with the correct name is shown in Device Manager.
A webcam is also mounted on the top edge of the case for convenient video conferencing. If you want to use “Windows Hello,” you can avoid the need to enter a password by using facial recognition. The camera can be positioned in different ways by rotating it. To flirt at the office without any hassle, you can also turn it all the way up. Then “Big Brother” only sees the flies on the ceiling.
In terms of connectivity, the Acer B248Y is very well equipped: HDMI, DisplayPort, and USB-C are available as inputs. The second DisplayPort is an output that can be used for daisy chain functions. The USB hub can be supplied via a USB-C or USB Hub Type B cable.
There are two USB 3.0 downstream ports on the back. Two more – more accessible for connecting a USB stick – in the bay on the left side of the back of the frame. A headset can also be added there. Another audio output is located on the back of the other interface – right next to the LAN socket.
The panel frame and panel surface are matte and effectively anti-reflective. Light falling from the edge or a viewer in light-colored clothing produces only a weak reflection on the screen. Gray Balance already does excellent pre-effects work. Our test graphic also immediately reveals that the Acer B248Y is not a simple display with a few additional features.
Grayscale appears very neutral throughout. The lightest levels are completely detectable and the deepest levels are covered up to 5. Even fine gray gradients display extremely well and colors are free from shimmer or banding effects. This is especially surprising because, according to the manufacturer, the device can display its 16.7 million color gradations with just 6bit + Hi-FRC.
The picture on the left shows a completely black image, as you would see it with the naked eye in a completely dark room; This is where noticeable weaknesses appear. On the other hand, the picture on the right with longer exposure times highlights problem areas and is only used for a clear representation.
Illumination is quite good and slightly above normal levels for an IPS panel. It also looks beautiful, especially in the middle. However, even with the central seating position, a slight glare can be seen in the corners – especially the bottom. They are largely neutral in color and are determined primarily by the viewing angle. The actual edge radiation is hardly observable (marginal on the edge in the lower right corner).
Measurements are made after calibration at D65 as a white point. If possible, all dynamic controls are disabled. Due to the necessary adjustments, the results are low when performing a test series with native white points.
The measurement window is not surrounded by a black border. The values can therefore be compared to ANSI contrast and reflect real-world conditions better than measurements for flat white and black images.
We only achieved a maximum brightness of around 179 cd/m² with the native white point. That is at least 28% below the manufacturer’s specification of 250 cd/m². The luminance can be reduced to a minimum of 53 cd/m².
After calibration, both values increase slightly. We measured 185 cd/m² for the maximum and 55 cd/m² for the minimum brightness. The manufacturer’s specification of 250 cd/m² is only achieved when the HDR mode is activated. But that has had nothing to do with HDR for a long time. However, the brightness in standard mode should be sufficient for working in normal office environments.
The manufacturer specifies the IPS panel’s contrast ratio as 1000:1. According to our measurements, it’s a very good 1075:1 after calibration.
The surface coating of the panel has a major impact on the visual assessment of image sharpness, contrast, and sensitivity to external light. We examine the coating with a microscope and show the surface of the panel (foremost film) in extreme magnification.
Microscopic view of the subpixels, with a focus on the screen surface: the Acer B248Y has a matt surface with visible depressions for diffusion.
Factory specification for maximum viewing angle is 178 degrees horizontally and vertically. These are typical values for modern IPS and VA panels. The photo shows the screen of the Acer B248Y at horizontal viewing angles of ± 60 degrees and vertical angles of +45 and -30 degrees.
The neutrality of viewing angles is generally very good with an IPS panel. While we’ve been testing displays at times recently that showed a significant drop in color temperature either horizontally or vertically, that’s not the case with the Acer B248Y. In the horizontal plane, the color temperature can be a little warm, but it’s only very subtle.
Above all, the loss of brightness and contrast is noticeable at extreme viewing angles. However, the Acer B248Y already loses some detail in dark areas from horizontal angles of about 45°. With our grayscale graphic, there are three to four levels. Other IPS panels can do it better. Hue and color saturation remain completely constant in any case.
The Acer B248Y also has an option to set the color space in the OSD. This is unusual for business monitor which is designed for video conferencing. The usefulness of this control is questionable, however, since a change in most cases simply leads to a change of the picture mode (for example “sRGB” or “Rec.709”), while other options (such as “EBU”) allow you to use the selected picture mode “Standard” remains. This is more confusing than it is useful.
In terms of color space coverage, the manufacturer’s information refers only to NTSC and promises a value of 72%. The following graphics show color space coverage in standard mode (“normal” color space) after calibration:
In the first graphic, you can clearly see where the sRGB color space coverage is still missing from the black network tip. On the other hand, the overhangs in the white mesh also show a clear overlap elsewhere.
In color management-enabled applications, coverage is not a major problem as it is corrected in the application. Outside of such software, however, there may be color space limitations. Incorrect or at least too saturated colors are displayed.
A “real” sRGB mode, which actually restricts the native color space, can help. The Acer B248Y also has a “real” sRGB mode. Underfunding is something big here. The overlap for this is practically completely removed.
The following image table below summarizes the results for factory preset and after software calibration:
We examined the response behavior on DisplayPort in native resolution at 60 and 75 Hz. The monitor was reset to factory settings for measurement. The response time, we determine for the black-white change and the best gray-to-gray change. In addition, we give the average value for our 15 measuring points.
The datasheet specified a response time of 4 ms for GtG. An acceleration option (overdrive) is available. There are “Off”, “Normal” and “Extreme” conditions. “Normal” is preset as the standard value.
With Overdrive switched off, we measured black-and-white change and the fastest gray change with 12.4 ms. Our 15 measurement points have an average value of 19.7 ms. Only the CtC value is somewhat pronounced at 22 ms. There are no overshoots to be seen, the tuning is very neutral. The response time for idle overdrive is quite acceptable.
At factory setting “Normal”, the switching time is shortened quite effectively without producing a noticeable overshoot. We measured the black and white change at 13 ms and the fastest gray change at 11.6 ms. Specifically, the mean value of our 15 measurement points is now reduced to 13.8 ms. You also can’t complain about the CtC value of 9.2 ms.
At the highest “Extreme” setting, the Acer B248Y can again improve significantly. We measured the black and white change with 12.2 ms and the fastest gray change with 7.6 ms. The mean value of our 15 measuring points is a fast 10.3 ms. The CtC value is also very good at only 5.2 ms. In return, however, there are sometimes significant overshoots. However, from our point of view, they generally remain within acceptable limits.
Latency is an important value for gamers, we determine it as the sum of half of the signal delay time and the average frame change time. At 75 Hz, the Acer B248Y achieves a very short signal delay of 3.6 ms. Half the average picture conversion time is 5.2 ms. This makes a total of 8.8 ms. The video conferencing monitor is also very suitable for gaming – especially since it also supports Adaptive Sync.
The backlight of the Acer B248Y is on continuously. The comparison in the diagram shows: with both full and low brightness settings, the luminous flux is not interrupted, as would be the case with PWM backlights. Thus, the screen is apt to work for long hours even with low brightness.
For sound reproduction, the Acer B248Y has two stereo speakers. Each of them has an output power of 2 watts. You can really do something with it. Volume control is set to 70% of the former functions, but the sounders remain fairly quiet here. However, it is not recommended to eliminate the maximum anyway, otherwise, the sound quality will suffer.
Sound signals can be received through all image signal inputs and played back through integrated loudspeakers or headphone outputs. However, the speakers are certainly enough to reproduce system sound or more informative video.
The Acer B248Y is a business monitor primarily aimed at commercial customers. Strictly speaking, any display that is not good enough for EBV or gaming can only be declared as a business monitor. After all, Word, Excel, and Co don’t require the highest color accuracy or fast response times. Even the integrated webcam and headset connection for video conferences makes it clear that Acer has given the B8 and cheaper B7 series under the “business monitor” label, which is otherwise often the case.
The Acer B248Y can initially convince with extensive ergonomic functions. They can be adjusted easily and accurately at the same time and are also supported electronically on the B248Y via the automatic brightness sensor. This model is also better suited for putting together multi-monitor systems. The affordable Acer B247Y already had a nearly frameless design. The Acer B248Y goes a step further as it supports daisy-chaining as well.
The overall connectivity of the Acer B248Y is quite good. DisplayPort and USB-C are still available. In conjunction with a USB-C one-cable solution, a complete docking station is supplied, which often allows mobile devices, in particular, to be connected to a wired network for the first time via a LAN port.
Even though the Acer B248Y video conferencing monitor is ultimately the first choice for office work, but its very good response time in gaming makes it a very interesting all-rounder for personal users as well.
The price of Acer B247Y is also quite low: $299.99 on Bhphotovideo.com, which will not be heavy on the budget of all users.
As a rule, the monitor is divided into gaming and professional, offering similar features. You can also see our MSI Creator PS321QR review is set to work with graphics but can adequately prove itself in dynamic shooters.’
