Vga Cable Plugged In But Not Working

I have one monitor plugged into the dvi output via a vga converter thing this works fine.

Vga cable plugged in but not working.

So i just received my alienware x51 and dell u2412m monitor. I have windows 7 x64. Check if there is any damage or something inside the port is preventing vga signal from getting through. This does not work at all.

Check to be sure that it is plugged into a power source that works and turned on. If necessary replace them with another identical signal cable e g hdmi or dvi to conduct a cross test. Monitor just says no video sighnal. First check the vga port.

Next if this does not solve your problem disconnect your computer dvd player or another input device from your cable and plug in a new input device. I tried replacing the cable just in case that was the problem but it did not change the issue. I have it hooked up to my computer with a vga cable using a dvi adapter as my video card only has 1 hdmi port being used by my main monitor 3 display ports and 1 dvi port. I have an intel i7 4790k cpu 4 00 ghz.

What do i do. If your monitor and cable are working it is possible that your input device is not. I m trying to connect a second monitor to the hdmi output by way of a hdmi to vga cable. It is an old 10 years monitor but works ok if i plug it into the dvi vga converter.

My computer runs windows 10 pro 64bit. Monitor not displaying through vga cable posted in internal hardware.
