Difference between Displayport, HDMI, and DVI

There are various terminals (standards) on the cable for connecting the personal computer and the LCD monitor.

Currently, HDMI is the most used, followed by terminals such as DisplayPort and DVI-D.

Image quality does not change with any cable

In fact, the quality of the image quality does not change depending on the type of this terminal.

The image quality is the same regardless of whether you connect with HDMI, DisplayPort, or DVI-D, and there is no problem with dual display with different terminals.

I haven’t seen it recently, but there is also a D-sub terminal (VGA terminal).

Since only this D-sub terminal is analog, the image may look slightly blurred or blurred compared to the current mainstream HDMI and DisplayPort.

The image quality is the same, but the resolution and refresh rate are different

All have the same image quality, but there are differences in the resolution and refresh rate that can be projected.

If you try this way, you can use HDMI, DVI-D, or DisplayPort for ordinary monitors.

(* DVI-D is a spec when using dual link, but since dual link is the mainstream these days, you don’t have to worry too much.)

With a single link, the refresh rate will drop and the resolution will drop.

“I was reusing the old monitor cable and it was a single link! ], So be sure to check it when you reuse it.

In addition, HDMI 2.0 and DisplayPort support 60Hz at 4K, and HDMI 2.1 supports 144Hz at 4K. There are no particular disadvantages to renewing the cable, so a new terminal is better if you use it.

DisplayPort is the mainstream of gaming PCs

HDMI and DVI-D are popular for the general public, such as video games, ordinary monitors, and notebook PCs. However, for PC games, DisplayPort is the mainstream.

When the latest graphics board look at the PC, which is mounted, DisplayPort three whereas such, HDMI and DVI-D is one and has become, you can see that DisplayPort is important.

Some graphics boards have two HDMIs, but there aren’t many types, and the standard one is three DisplayPort types.

DisplayPort is required for multi-display environment

To increase the number of monitors to two or three screens, you need a clock generator, which is only installed on a normal graphic board.

In other words, it can only be done on two screens.

However, except for DisplayPort, DisplayPort does not need a clock generator. Therefore, if you use DisplayPort to make a multi-display, you can support more than two screens.

It seems that there are some graphics cards that can be used for multiple displays without using DisplayPort, but even if you don’t bother to find such a special graphics card, you can choose a graphics card equipped with DisplayPort.

The monitor and cable must support 144Hz

Even if you use a cable that supports 144Hz, if the monitor does not support 144Hz, it will only be 60Hz.

On the contrary, even if you are using a gaming monitor, if you connect it with a terminal that does not support 144Hz, it will be 60Hz.

Depending on the type of gaming monitor, even HDMI 2.0 doesn’t work at 144Hz and you have to use DisplayPort.
