I have recently bought the Plugable UD-3900 docking station and a second Samsung S22E450 monitor to go with the one I already have as i needed 2 monitor for my home workstation set up
The current (older) monitor is connected to the dock via HDMI – this is Display 2. The new Samsung monitor is connected to the dock using DVI – this is Display 3.
The issue is that Display 2 has a resolution of 1920x1080 but Display 3 only has 1680x1050 and is not as sharp. Changing the display settings on my Windows 10 laptop doesn’t solve the problem – it stubbornly remains on the lower resolution.
Am I doing something wrong? I want full 1920x1080 resolution on both of my screens.
For the benefit of anyone else following this thread, the cause of the problem in this specific case was determined to be the monitor itself.
To expand further, Samsung has made many different versions of the S22E450 display.
In this specific case, the older monitor the customer was using was a S22E450F model (note the ‘F’ at the end) and this model has a maximum resolution of 1920x1080.
The new monitor the customer purchased was a S22E450DW model (note the ‘DW’ at the end) and this model has a maximum resolution of 1680x1050.
To put that another way, the docking station was working as expected. The cause of the problem was that the new monitor (which is in fact a different model compared to the original) had a lower maximum resolution.
