DVI vs HDMI vs DisplayPort vs VGA Comparison
There are different types of display interfaces and cables available to connect your monitor to your computer or other video device. They are VGA, DVI, HDMI and DisplayPort interfaces and cables. Here I talk about these display interfaces and cables and tell you how they are different from each other.
VGA (Video Graphics Array)
VGA or Video Graphics Array is the oldest way to connect your Monitor to your computer or video device. A VGA cable carries analog signal which does not produce great images or videos on your latest LCD monitors.
VGA connectors are virtually absent on modern day graphics cards which generally come with DVI, HDMI and DisplayPort connectors. The maximum resolution supported by VGA adapter is 1920 x 1080 at 60 Hz (or higher resolution) but the quality of video degrades with increase in resolution, cable length & quality. VGA adapter is also not recommended for gaming because the lag in video signal (due to analog conversion) and somewhat inferior display quality. You should only use VGA cable when you have an old monitor that only supports VGA cable; otherwise go for the other better options mentioned below.
DVI (Digital Visual Interface)
DVI or Digital Visual Interface offers digital signal and has very good display quality as compared to VGA. The maximum resolution supported by single link DVI cable is 1920 x 1200 pixels and by dual link DVI cable is 2560 x 1600 pixels at 144 Hz refresh rate which makes it great for gaming purpose.
There are three types of DVI connectors:
- DVI-I (integrated, combines digital and analog in the same connector, digital may be single or dual link)
- DVI-D (digital only, single link or dual link)
- DVI-A (analog only)
DVI-D connector is very common and is used in most of the cables and systems.
HDMI (High Definition Multimedia Interface)
HDMI or High Definition Multimedia Interface also carries digital signal but it can carry audio signal too. HDMI cables are great for connecting HD TVs or monitors with inbuilt speakers as both video and audio can be carried over a single cable only. The maximum resolution supported by HDMI cable is 3820 x 2160 pixels at 30Hz, and it is good for gaming as well as for watching HD movies and playback.

DisplayPort is the best and advanced way to connect your LCD monitor to your computer or video device. DisplayPort 1.3 can also be used to run multiple monitors with a single cable only. DisplayPort can support maximum resolution of 3840 x 2160 at 60Hz and the cable can carry audio and USB data too. If you are gamer and your monitor and graphics card supports DisplayPort then I would advise you to connect your card to monitor using DisplayPort cable only.

Hello Akshat sir,
I have Tata sky HD setup box and Samsung Tv. I have connected it with HDMI cable.(setup box HDMI port and Tv with HDMI port)
My problem is that from few days the picture output from setup box to my tv is not proper. My tv screen goes blank for 3-4 seconds but I can hear voice from tv i.e. setupbox is working. If I remove HDMI cable from setup box my tata sky box works perfectly i.e without any signal problem. I think HDMI port on my samsung TV is not working because I checked cable with other TV and it worked perfectly. Also when i connected setup box and samsung tv with Av to Av connector there was no such issue i.e. by tv does not go blank for 4-5 second but picture quality had deteriorated considerably.
I thought a HDMI to AV cable will solve my issue without compromising picture quality, Please guide me. link of cable I am planning to buy.
Thank You. Awaiting for your reply.
