Does display cable make a big difference?

[ramyhammam5]

I normally use a vga and connect it to my card via a vga to dvi adapter, does using a display port or hdmi make a difference compared to vga or dvi?

Short answer, no practical differences to be concerned about when choosing between DP (Display Port) or HDMI.

DVI does have limitations however, and VGA is pure analog and thus obsolete.

Note: If going 4K and opt to use HDMI, it will need to be HDMI 2.0 supported to the video card.

VGA is an old analog technology. On a 1080p monitor, I can tell the difference if it's connected using VGA or a digital connection. Use DVI, HDMI of DP!

VGA is analog. The quality of the image depends on the quality of the graphic card's D/A converter (or in your case, the VGA-DVI adapter's D/A converter), the quality of the monitor's A/D converter, the quality of the cable, and the amount of RF interference in the immediate vicinity which the cable can pick up. Poor performance in any of these can result in blurry or washed out images, or interference like waviness or lines washing over the image.

DVI-D, HDMI, and DP are all digital. The only difference a poor quality GPU interface, cable, or monitor interface circuitry makes is how long the cable can be before you lose the image. If the interface (on both your GPU and monitor, plus the cable) support the desired resolution and refresh rate, and the cable is short enough, it will work and all will produce the same image (other than differences in monitor settings).
