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)?Under display properties, does it give you option to span the displays as Display 1 and Display 2?

Also what video card or integrated GPU does your system have?

Display Port to HDMI adapters would be needed if connecting to the monitors with HDMI.

Something like these adapters: https://www.amazon.com/DisplayPort-Converter-Connector-Projector-HDTV-Black/dp/B0824G74BP/ref=asc_df_B0824G74BP/?tag=hyprod-20&linkCode=df0&hvadid=432926973346&hvpos=&hvnetw=g&hvrand=15793319671950647869&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9002910&hvtargid=pla-906014556903&psc=1&tag=&ref=&adgrpid=101482724780&hvpone=&hvptwo=&hvadid=432926973346&hvpos=&hvnetw=g&hvrand=15793319671950647869&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9002910&hvtargid=pla-906014556903Hi thank you for your answer.
At the  moment I connected two displayport to hdmi from the tower.  Weirdly, 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 that way, 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.
Don't know what video card or what integrated GPU I have or how to know.
Running Windows 10.
What Make/Model Computer? ( This can be used to determine the GPU Video Card info.)Sorry for delay in answering. I'm not sure how to know exactly, I know its DELL and on the front it says Optiplex 7010 if that helps.Intel HD GRAPHICS 2500 Dynamic Video Memory Technology

If this is the tower (MT) you could add a video card to it to solve this and if its a (SFF) Small Form Factor you could find a Low Profile Video Card that can SUPPORT the extended display better than the integrated would.

As long as not heavy gaming you could get by with a newer NVidia GT type video card. If you plan on video games GTX is the way to got for NVidia. However most GTX cards require a power supply upgrade and the SFF version of this computer will be a problem in finding a heavier WATTAGE power supply to drive a GTX type card.You can add a video card to accomplish this. If you have a small SFF (SFF), you can look for a Video Game Card that can support a better message, instead of a mixed case.
