D-Sub and DVI: standard interfaces for PC use. When used as a monitor interface, a D-Sub port is also known as a VGA port, an analog connection standard that's been around for some time. The connector is a DE-15 connector with 15 pins in three rows, often referred to as a "mini-D-Sub 15-pin" or "D-Sub 15-pin" connector.
Regarding this, what does D Sub mean on a computer?
D-Sub refers to a "digital sub-miniature" cable connection. The VGA D-Sub cable uses a D-shaped connector containing 15 pins.
Also, is HDMI better than D sub? HDMI is audio and video (so you can use your monitors on board speakers if it has them without the need to wire it up from a sound card). DVI is video only. Both are digital signals so they give the best video quality. D-Sub is VGA, an old analogue signal standard, you can't use this on a digital only monitor.
Consequently, is DVI better than D sub?
DVI is capable of transmitting both analog and digital signals its D-sub equivalent (the DE9) only carries analog signals. Though other D-sub connectors like the serial port uses digital signals, the provisions in the VGA standard only allows analog signals.
What are the ports on my monitor?
Different types of monitor ports
- HDMI: Audio and video signal, best for TV to PC connections.
- DVI: Video only, perfect for older systems or for 144Hz at 1080p.
- DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K.
- VGA: Old, legacy video connector.

What does D sub do?
What Is a D-Sub Port? D-Sub ports are used for connecting external devices to a computer. They are an older method of connection, but some modern computers still contain them. These ports are gradually being replaced by more efficient connection technology, such as USB and Thunderbolt.Should I use VGA or HDMI?
HDMI is really best for connecting a PC to an HDTV. Consequently, I'd go with a DVI cable. That'll give you a pure digital signal (VGA is analog) and a much sharper picture at higher resolutions. Your Dell ST2210 has a native resolution of 1,920 x 1,080, which you can and should use.What's better HDMI or VGA?
VGA is an older standard that carries only a video signal. HDMI can carry both digital video and audio signals, all while encrypting data with HDCP. The video quality attained with a VGA cable is noticeably worse when compared to that of HDMI.Can VGA do 1080p?
VGA can indeed support 1080p. The quality of the signal begins to drop off above 1920x1080 (1080p) which will cause a drop in image quality due to the analogue nature of the signal but with a good enough cable and transceiver on either end it can be used for resolutions up to and including 2048x1536.Is VGA and D sub the same?

What does DVI look like?
A DVI connector is characteristically colored white (as opposed to a VGA connector which is colored blue). Some NVIDIA based graphics cards will look similar to Figure 2 which features a DVI-D connector as well as a VGA connector. These cards generally will only support a single display at a time - not dual monitors.Should I use HDMI or DVI for gaming?
HDMI and DisplayPort are different connections that both support 4K resolutions. 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.Can HDMI run 144hz?
Yes, HDMI 1.4 can support up to 144Hz at 1920×1080. However, not all monitors with HDMI 1.4 necessarily do as well. Many monitors with HDMI 1.4 are also limited to 120Hz at 1080p. Moreover, all monitors with G-SYNC are limited to 60Hz over HDMI.Does DVI carry audio?
Whether it's DVI-I, DVI-D or DVI-A, however, no standard DVI cable will transmit audio — not without a little tweaking at least. If you want to transmit audio over DVI, you'll need to use a special DVI-to-HDMI cable.Is DVI better than VGA?
YES, IT IS - The main difference between VGA and DVI is in picture quality and the way the video signals travel. VGA connectors and cables carry analog signals while DVI can carry both analog and digital. DVI is newer and offers better, sharper display compared to VGA.What is the difference between DVI I and DVI D?
As already mentioned, a DVI-D connector sends out a digital signal only, whereas a DVI-I connector can send both a digital signal (for digital displays, such as flat panel LCD monitors) and an analog signal (for older displays, such as a CRT monitor) using a DVI to VGA adapter.Does Gsync work with HDMI?
Do G-SYNC Compatible displays work on both DisplayPort and HDMI with GeForce GPUs? G-sync Compatible displays will only support variable refresh rate over DisplayPort when connected to GeForce Pascal or Turing GPUs.Which is better DVI or DisplayPort?
HDMI: Audio and video signal, best for TV to PC connections. DVI: Video only, perfect for older systems or for 144Hz at 1080p. DisplayPort (DP): The best connector for an audio and video signal, and can transmit 144Hz up to 4K.Does VGA carry audio?
VGA cable (15-pin D-shaped connector) does not carry sound. You'll need separate cable from your computer' audio out / headphones port to TV' audio IN.How do I convert VGA to HDMI?
To do this, it is necessary to pass the VGA signal through a converter, which will take the VGA analog video signal and the stereo audio signals and convert them into digital signals which can then be sent out across a HDMI cable for connection to a monitor with a HDMI connector.What does D Sub mean?
The D-subminiature or D-sub is a common type of electrical connector. They are named for their characteristic D-shaped metal shield. When they were introduced, D-subs were among the smallest connectors used on computer systems.How do you attach two monitors to a laptop?
1) Plug the cable of the first external monitor to the correct video port on your laptop. So I plug the VGA cable of the first external monitor into the VGA port on my laptop. 2) Plug the cable of the second external monitor to the other correct port on your laptop.
