I have a Dell computer (tower) that runs Windows 10, I used to be able to connect my Orion TV to the computer via VGA, I think that was before I had upgraded to Windows 10. Now, if I try to connect it, the TV will say "Not Supported". I have an HP vs17e monitor connected to the computer right now via VGA. I would like to be able to use my Orion TV as the monitor, but I can't seem to fix the problem.

edit: I forgot to mention that my Orion TV is connected to a laptop via HDMI

I can't do that because my tower doesn't have an HDMI port. The Model Number to the Dell is 'DCNE'. The link below shows an example of how the back of the tower looks. The Serial Number is '94BV63J'. I believe my Dell is integrated. And my Orion TV Model Number is SLED1945.

Also, I'm not sure if this is worth mentioning, but when I plug the VGA to the back of the TV, it works for a split second, but the TV goes back to saying "Not Supported".
