I have a MS Surface running Windows 10 and two additional Samsung screens. Running it as a dual screen leaves the second screen blank.

This is the exact same set-up I have had working previously, so I know it can work. I have had the Surface replaced under warranty and now the second Samsung monitor remains blank.

It gets detected fine. It's just blank. If I unplug the other screen then the blank one lights up, but only with what was previously on the other screen. Plug the other one back in, and the display goes blank again.

Both screens are listed under Monitors in Device Manager as Generic PnP Monitor. Driver is Intel (R) Iris (R) Plus Graphics 640

Help would be much appreciated!

Check your display settings with all 3 plugged in. It may just needs to be identified or detected from with in windows. So click on detect first and then click identify.

Question: Are you wanting you use all 3 screens as a single screen? If so make sure it's set up to "Extend" displays.

I don't get any options to do anything with the second screen.

What i'm after is to have the same on screens 1 (the Surface) and 3. I don't really care if the Surface display is blank, i never look at it. Screen 2 is just an independent screen. Or it should be....

So, it looks like the problem is the second display "isn't active". How do i make it active?
