build a gaming pc yesterday that doesn't support vga cables. I have everything plugged in right now and the monitor wont turn on however the gaming pc turns on perfectly. Everythings plugged in great for the monitor except the vga cable. Might that be the issue?
I’m new to PCs and I’m just wondering what these ports do on my new pc. I tried putting my second monitor in the VGA and I just get no signal.

What is VGA?
Reccomendations for a 32" monitor with VGA port?
Can I use a VGA monitor with a gaming console?
Yes, you can use a VGA monitor with a gaming console by using a VGA-to-HDMI or VGA-to-component video adapter. These adapters convert the console's video output into a VGA-compatible signal that the monitor can display. However, keep in mind that VGA monitors may not provide the best gaming experience compared to monitors with higher resolutions and faster refresh rates.
Does a VGA monitor support widescreen resolution?
VGA monitors typically have a 4:3 aspect ratio, which means they are not optimized for widescreen resolutions. However, some VGA monitors may support widescreen resolutions through letterboxing or stretching the image to fit the screen. Keep in mind that this may result in distorted or cropped visuals, depending on the monitor's capabilities and the resolution being used.
Can I use a VGA monitor as a secondary display for my laptop?
Yes, you can use a VGA monitor as a secondary display for your laptop by connecting it with a VGA cable or adapter. This allows you to extend your laptop's desktop onto the VGA monitor for multitasking or presentation purposes.

Computers detect screens by something called Display Data Channel
It's a low rate data signal on four pins in the VGA connector that tells the computer about its presence, allowed modes and frequencies, etc.
You can still use a screen without DDC, but you need some pull-up or pull-down resistors to tell the computer there's a screen at all. You'll also have to force the adapter to produce the signal, and you'll have to set up the monitor parameters manually.
A simple, easy way that may work is to ground the VGA out pins 4, 11 (DDC 0/2), which will put the display mode to > 1024x768 color. I have a HDMI-VGA converter that uses the DDC pins to detect the presence of the monitor, and turn on/off the audio output (it also extracts audio from HDMI) accordingly.
