Just received and so far it’s superb! With one little issue…

I’ve got DVI > DVI working great on my primary monitor. Then I connected the HDMI output to DVI on the second monitor using https://www.amazon.co.uk/AmazonBasics….

I get a picture on screen, but am unable to set it up to extend the desktop (Windows 10), it just doesn’t fully recognise the monitor - it mirrors my other DVI output.

First thought was the cable is not bi-directional but I read that this is not a problem for HDMI-DVI cables - they can work either way round.

If I use a HDMI to HDMI cable, it works fine and I can extend - but the monitor is awful quality when using HDMI input - whilst DVI is spot on.

Any thoughts?

Both monitors resolutions are 1920x1080 and in addition the laptop display is 1366x768. I’m aiming for the two external monitors on DVI plus the laptop running natively as it always has. All monitors will be independent and extend the desktop.

Okay, fixed. It’s an easy one too - albeit I missed it at first…

I thought the middle display in the screenshot above said 213 not 2|3

To fix this under multiple displays you can choose to extend on 2 and 3, and then it appears like I needed.

Now working perfectly.

Hi Philip,

Thanks for posting. I am sorry that the originally the monitor configuration was confusing, however you did great job of providing all the detail and working through the problem to reach the resolution, very well done. For the benefit of anyone else following this thread, we have also made two short videos showing the basics of how multi-monitor setups work in Windows and the common issues our customer may run into here:
