If you still use VGA you may want to consider upgrading.

This means VGA signals transmit information via electrical wave size.

HDMI digital signals transmit data in bits of data (on or off) in varying frequencies.

VGA vs HDMI

Lifewire

Overall Findings

Adapters can convert to HDMI.

Max refresh rate of 60 Hz

Max resolution of 1600x1200

Supported by modern devices.

Transmits video and audio.

Max refresh rate of 240 Hz.

UXGA could support 15" monitors at 1600x1200 pixels.

High Definition Multimedia Interface (HDMI)was developed in 2002 and soon became the new standard for computing.

HDMI supports HD video at 1920x1200 pixels and 8 audio channels.

Few devices support VGA anymore.

You’ll find most computers and TVs have an HDMI port and no VGA port.

Compatibility: Modern Monitors Use HDMI

Available on older monitors.

Supported on older graphics cards.

Converters degrade the signal.

Available on newer monitors.

Adapters can convert to VGA.

Supported by most graphics cards.

However you likely will need a VGA to HDMI converter to connect to any modern monitors.

Audio: HDMI Supports High Definition Audio Signals

VGA only transmits video.

Requires second audio output.

Newer graphics cards do not support VGA

Supports 32 audio channels.

Supports Dolby, DTS, and DST high-resolution audio.

Doesn’t require second audio cable.

HDMI supports most high definition audio signals likeDolby Digital, DTS, and DST.

If it doesn’t, you’ll need to connect your box’s audio to separate speakers.

Data Transfer Speed: HDMI Is Far Superior

Maximum refresh rate of 85 Hz.

Maximum refresh rate of 240 Hz.

Almost no signal interference.

AnHDMI cablehas 19 or 29 pins and transmits video and audio.

HDMI 2.0 is capable of achieving 240 Hz at 1080p resolution.

VGA on the other hand has 15 pins and uses an RGB analog video signal.

This analog signal is only capable of a refresh rate from 60 Hz to potentially 85 Hz.

you’re able to’t do this with VGA.

You’d need to stop the video stream or turn off the computer before plugging in the VGA cable.

VGA signals are also subject to significant signal interference from outside sources like microwaves or cellphones.

HDMI cables are far less susceptible to this, and with thick shielding almost completely impervious to interference.
