for the connection of a monitor on the Galaxy-S8 docking stationDeX provided a full HD monitor. In pixels and screen format means the 1920 x 1080 and 16:9
so far, so clear. But what about other monitors? The resolution is scaled or surrounded the area represented by a black border? Can you use an HDMI-to DVI adapter for connecting a full HD monitor with DVI connector? These and other questions to the testing of the DeX station reached ZDNet.de. The following article will answer some of the questions.
HDMI-to DVI adapter / HDMI-DisplayPort adapter
the control of a monitor via a HDMI-to DVI adapter with Samsung DeX is no problem. In this case, but no sound is transmitted. May be speaker present in the monitor cannot be used so for audio output. Even if the monitor has an analog audio input. Because, if the Galaxy S8 is in the docking station, the headphone output of the Smartphone is useless. Therefore, an analog audio transmission is not possible.
In the test, the image transfer to the Samsung C27F591 monitor via a HDMI-DisplayPort adapter did not work. The monitor was taking only via HDMI in conjunction with DeX in operation.
27-inch monitor with 2560 x 1440 pixel
a 16:9-monitor with a resolution of 2560 x 1440 pixels (WQHD) can be operated with the Galaxy S8 and the DeX station into operation satisfactorily. In this case, the resolution of the test model BenQ GW2765HT is however only full-HD. The monitor scales the image but on the whole size. There is no black borders so. However, the appearance is not as sharp as with a native control.
23-inch monitor with 2048 x 1152 pixel
the Samsung 2343BW features an unusual resolution 2048 x 1152 pixels. Although this 16:9 format corresponds to and he can be also full-HD, if only scale, Samsung DeX represents only 1280 x 720 pixel on the monitor. Also, the image is centered, surrounded by black edges in the center of the monitor.
in the settings of the monitor the display option”Broadband”can select. Thus, the appearance is not better. While the lateral edges disappear, but overall the picture is rather fuzzy.
TV with 1920 x 1080 pixel
which provides connection of Samsung DeX on a 46-inch led TV no problem dar. However, the display is pixelated due to the size of the display.
conclusion: monitor compliance by Samsung DeX
best full HD monitors with a size of up to 24-inch are suitable for the use of Samsung DeX. This controls the Galaxy S8 via the docking station at their native resolution and the size of the monitor guaranteed still a sharp display. For this purpose, also DVI models can be used. A trouble-free start-up was possible with a HDMI-to DVI adapter.
with a 27-inch monitor like the Samsung C27F591 is the appearance in comparison to a 24-hour or 24-inch clear coarse.
the same applies to the connection of 27 combined with a resolution of 2560 x 1440 pixels. Although Samsung DeX makes optimum use of the surface of the display. But the appearance is not optimal due to the scaled resolution.
monitors in 16:10 or 16:12-format stood for this test not be available. In the face of experience, their use in conjunction with Samsung DeX is not recommended. Probably you will have to accept black borders or but a fuzzy appearance with these models. For more information about Samsung DeX
