Good evening all,

New to these forums as I usually like to work at finding the problem myself but I'm stumped, granted the problem at times can be between the CHAIR and the keyboard. 

Bought the two monitor pack of the model listed in the subject line (https://www.amazon.ca/gp/product/B01GQP7NXO/ref=ppx_yo_dt_b_asin_title_o06_s01?ie=UTF8&psc=1) and also to replace two dated 23inch Dell S2309W from 2010. My Dell MONITORS I believe operated on DVI ports of which my PC has three. To my surprise when I opened the box with both new monitors, two separate cables were present. What I believe are the blue-headed VGA cable and a cable for a display port.

Both monitors have three ports, VGA, DVI and digital
I plugged the one I wanted as primary, digital port to digital port PC (only one) and VGA cable the second monitor.

Monitors turn on but no signal.

I then tried the DVI cable from my old monitors on new monitor and to PC DVI port, no signal.

Finally I tried the VGA port monitor to PC with the same result.

The only thing I can think of is that my video card is quite old but I can still play some very recent games (or could) even as pf LAST week (not sure if that's relevant).

Any input or insight would be truly appreciated. Hope this message finds you well.Sorry all that should read "display" port and not "digital" for CLARIFICATION.
