While the original VGA (VGA standard) had a maximum resolution of 640×480, nowadays the VGA cable is capable of 1080P and higher resolutions.
No, you don't need a VGA cable, but you do need a video cable, be it HDMI, DVI, VGA or Display Port. Some monitors aren't smart enough to detect video source, so you may have to select "HDMI" with one of the buttons on the monitor. You may have multiple video cards and/or video ports.
You have several options: You could buy a VGA + Audio to HDMI converter this connection. This device will connect to your PC using VGA and Audio and to your TV using HDMI. The Analog VGA and Audio signals from your PC are converted in the device and muxed into an HDMI signal that is sent to your TV.
VGA is a signalling specification, never designed to carry power to anything.
Tried a few different video cards and switched between the 17" and the 23" wide screen using both cables. The heavier VGA cable is better than the thin one, especially on the larger screen. It's not DVI quality but it's an improvement when using old cards with a larger LCD that's trying to stretch the image out.

The first one is that VGA is an analog interface. HDMI is a digital one. The second difference is that VGA is a video interface and HDMI includes both audio and video. Typically, devices with the VGA interface have lower video resolution compared to modern HDMI devices.
It is not as common to use projectors anymore, and most laptops no longer include VGA as a connection option. However, it is possible to transmit a picture from your computer to a projector with an adapter.
Any modern desktop or laptop PC has the graphics capability to run dual displays. All that's required is a second monitor. While it is common for VGA and DVI cables to come included with the display, you may have to purchase your HDMI or DisplayPort cable separately.
VGA and SVGA cables both use the same pin configuration. In traditional desktop computer setups, a cable connects a computer to a monitor. A video graphic array (VGA) cable carries analog signals and supports video resolutions up to and including 640 x 480.
From the computer's “Control Panel,” click “Hardware and Sound” and then “Connect to an External Display.” Select the VGA monitor from the “Display” drop-down menu and click “OK” to switch to the VGA monitor.
Maybe it's just me, but in my 15 years in IT, I've never seen a VGA cable go bad (aside from physical damage, such as bent pins or pinched wires). During troubleshooting for video problems, I'll easily swap out monitors, adapters, and/or graphics cards long before I'd narrow it down to the physical cabling itself.
VGA having no signal means that your monitor is powered on but not connected to a video card, so you should make sure the connection is working properly.
A VGA output on your computer to an HDMI input connection on a monitor will require an active adapter or converter to convert the signal from analog to digital. A passive adapter that just changes the plug end will never work. Scaling is when the converter takes your VGA resolution and makes it fit your HDMI TV.
VGA makes some sense because many newer computers still include VGA connections and there are millions of older computers that do. It ensures backwards compatibility with older computers which use legacy graphics cards. That being said, most newer mainstream monitors now exclusively use DVI-D, DP or HDMI.

An HDMI cable supports HD videos and sends both audio and video in the same port. It's easier to obtain and is lighter, faster, and more reliable compared to the VGA. It delivers a crisp image resolution of 1,920 by 1,200 pixels and uses eight audio channels at the same time.

VGA - 150 feet (regular); 650 feet (with extender)VGA is an analog signal and will get weaker over longer distances. For high-quality video, the maximum recommended distance is 25 feet.
HDMI is the best choice if you are just connecting a gaming console, blu-ray player or streaming device to your TV. DVI is a good choice if you're looking to get the most out your high frame rate on a 1080p monitor.
