Hi Kaushal,

Thank you for posting! I am sorry things are not working as expected while using your UD-3900 docking station and I would be happy to help.

Thank you as well for the detail you have provided that is much appreciated.

Based on your description, our next step is to get some additional information.

  1. Can you please let me know the specific model numbers of each of the two Samsung displays you are using?

  2. If two different models are in use, can you let me know which specific model is currently affected by the problem?

  3. Can you let me know what type of video cable is being used to connect the affected display to the dock? For example VGA, DVI or HDMI.

  4. Can you please provide a photo (for example taken with a mobile phone) that clearly shows the problem behavior and include that in your next reply? This will allow me to ‘see’ the ‘stretched’ behavior you are describing. ** Important note, a screenshot of the behavior taken from within Windows will not work. It must be a photo taken with an external device like a mobile phone. **

Thank you for giving us the chance to help!

Hi Kaushal,

Thank you for getting back to us with the additional information, and I appreciate the excellent detail you provided and the annotations shown in your photo.

Based on that information, I believe you may just need to use the ‘Auto-adjustment’ option within the Samsung display on the left-hand side of your desk to resolve the problem.

To expand further, when a display is connected using a VGA video cable there are some cases where the display has to be adjusted so that the image fits properly within the display.

Most displays have an ‘Auto-adjustment’ feature built-in to the display that can (as the name implies) automatically adjust the image.

The manual for your display → http://downloadcenter.samsung.com/content/UM/201906/20190618104444943/BN46-00552H-Eng_for_India.pdf shows how to access this option on page 10:

If you use the auto-adjustment option within the affected display as shown in the manual, does that help resolve the problem?

If you are unfamiliar with this process or need to make further manual adjustments, I made a short video that demonstrates this process in action here → https://youtu.be/KYyZgocwvms

The display shown in my video is a Dell U2412M display, but the concepts demonstrated are the same.

Thank you,

Bob
