How do I cable connect for extended display?

July 16, 2020 at 06:43:48
Specs: Windows 10
Got two monitors, each with one vga and hdmi ports, and a desktop tower, with one vga and two displayports. How do I cable connect them for extended display, (not mirror)?

These "how to" may help?

You'll also need display port to hdmi adapter for each monitor; and an hdmi cable for each monitor as well.

Hi thank you for your answer.
Haven't yet read the links but will do soon.
At the moment I connected two displayport to hdmi from the tower and as you said two hdmi cables from the monitors. There doesn't seem to be a cable running the other way around, that is, hdmi to displayport, that I can connect from the monitors. And incidentally, I have to setup for extended display BEFORE I turn on the second display otherwise the second screen will be black.
When I do connect the way it is now, one screen is normal but the other screen won't show anything other than the desktop. For example, if I click Start, the menu shows, but when I click for a program to come up, (eg Paint), nothing shows.
Running Windows 10.

There are specific displayport to hdmi cables about.

Amazon have them and likely many other vendors too.

I tend to advise going for better quality than the cheapest... and where possible check reviews of a given cable, as reviews often highlight issues and differences between cables...

Adapters are of course useful if you wish to replace a given cable...?

The links I posted above ought to help you set up the extended desktop arrangement. I used to find it relatively simple to do when I used windows (XP and earlier...) but nowadays I'm running Mac systems. so can't confirm it at my end.

Have you tried to connect 1 VGA + 1 display-port?
Do you have the same problem with extended display setup?

Apps, started from my extended display, open in the "main" display...

If it's showing the desktop, then that seems to be working as an extended display. If you want a program to open in that window, first launch the program, then click the reduce size icon in the upper right corner of the program. Put your mouse in the title bar of the program, hold the left mouse button down and drag it over to the extended display. Click the maximize icon in the upper right hand corner. Now the program will automatically open in that display from now on when you launch it.

Hi THX1138, just saw your answer. The problem is no program will launch, (that is visible to me on the second monitor anyway), for me to able to resize it.

It should launch on the primary monitor, then drag it over to the extended monitor.

My memory is (albeit a little vague on this just now) is that in windoze, if you have set up extended screens system and then opened an application (as per THX suggests) and drag it onto the second screen... when next you open that application It will do so on that second screen.

What one has to remember is that if you close the app and disable the second screen sharing and then re-open the app it remains there on the now gone second screen... I.e. you can re-open the app but it won’t show on the main screen - until you use the correct key combination to get it back to the main screen,

Can’t check all of this out at present as I ain’t running windoze nor a second screen. But I thinks I’’ze right about it.

Tried the suggested method of dragging - afraid it didn't work.

I wondered if I had it cabled connected it right, if there are other ways to connect or the cables have nothing to do with this problem?
