You need a HDMI-to-VGA adapter. Your laptop is outputting an HDMI signal which has to be converted to VGA.
Some connectors are physically different, but use identical signaling - in these cases a passive adapter is sufficient. Passive means there's no signal transformation necessary. It's just two different connectors wired together. For example, DVI-A is just repackaged VGA (aka D-Sub) and they can be passively adapted both ways. Similarly HDMI uses the same signaling as DVI-D, so you can convert between them without any electronics - just wires.
HDMI and VGA are completely incompatible, so you need an active adapter which will decode the HDMI signal and produce equivalent VGA signal.
You may be tempted to use a passive HDMI→DVI adapter and then a passive DVI→VGA adapter, but this won't work. HDMI would be converted into DVI-D, and the second adapter needs DVI-A input. DVI-D and DVI-A use physically compatible connectors, but the signal won't go through.
Note that while active adapters are directional (HDMI→VGA is completely different than VGA→HDMI), passive adapters are usually not. As long as passive adapter's plugs physically fit, it will work in both directions. So for example a HDMI→DVI adapter would work for DVI→HDMI too.
Answer from gronostaj on Stack Exchangeis a vga cable necessary to connect a monitor to a pc if you already have an hdmi?
Nope not needed.

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?

Many people get this the wrong way round.
Signals go from > to
You might think you're connecting your display to your computer, but you're not. You're connecting the computer to the display.
This means your signal goes from the computer to the display - that's an HDMI to VGA connection.
HDMI is a digital format, VGA is an analog format, so any connector you get must be an active connector.
So I have a new work laptop, and I would like to keep using my old monitor with it as a second screen; but it only has HDMI and USB 2, USB 3, USB C ports...
I did buy a VGA-HDMI converter but it was hardly working at all (the image was atrocious). It could be because I bought a cheap one, but before investing in a 30quids+ one I would like to make sure I am not throwing money away.
Or perhaps there is another option - I honestly do not know. (Get a docking station which connects with an USB?) Any suggestions are very much welcome. Thank you
