Windows 10: Display Setting issue after connecting DP

So I am sorry to ask this but its got me beaten so far.


I have an Win 10 Lenovo laptop - very modern and capable.


I bought some screens for it and as they were cheap they are not HDMI so I got some VGA-HDMI cables and they work fine and I run with 1920x1080 resolution.


All good so far


I wanted to run 2 screens rather than one and so found a Dell Display Port in my big box of IT kit and so using the HDMI cable I had plugged into my laptop, I left the VGA end plugged to the monitor, plugged the HDMI end into the DisplayPort and then plugged the display output cable into a USB port...sure enough I got a display but only a very poor 640x480 resolution. In display settings there is no option to change this....grey'ed out


So rather than mess about too much I disconnected it and plugged the hdmi back into my laptop.


From this point on I get nothing on my monitor. Display settings cannot detect it. I plugged another screen in and its fine.


Its like the monitor has been told you are to run at 640x480 and as my laptop minimum is 800x600 it no longer recognises the monitor.


I tried swapping cables

I updated drivers

I tried a factory reset on the monitor

reboot the laptop

plugged it into another (identical) monitor and its OK

plugged a different laptop in and it is the same - no display


only when I use the displayport now do I get an image and just a poor one


The monitor is a hanns-g HE225


Any ideas?


As Im writing this I am seeing that the issue surely is with the Monitor

Sudden Triple Monitor Issue - The display settings could not be saved

Okay couple of suggestions here...
First off I'm gonna start with the basics and tell you to go to amd website and reinstall the drivers. (Remove them first)

Second I would say look and see if the monitor is faulty. Plug it into one of the other ports and obviously see if it works.

Third, I would probably go ahead and replace the card considering you have had It for 3 years. I would suggest an EVGA GTX 750 TI for about 150$
