VNC Bandwidth Requirements

Save

VNC is a desktop-sharing application that lets you access and control another computer across the Internet. Although VNC allows you to use a system as if you were right in front of it, the speed of your Internet connection and other factors limit the quality of the image as well as response time. Determine if you meet the bandwidth requirements for VNC to decide if the software is right for you.

Connection Speed

  • VNC will automatically adjust itself to work with any Internet connection. The slower the connection, however, the more the quality of the image will decline. Generally slower connections are suitable only for text-documents. Those wishing to view high-quality photos or other system-intensive tasks need a very fast broadband connection.

    According to the makers of VNC, a 33 kilobits-per-second (kbps) connection is adequate for accessing computers with very simple graphics at a reduced frame rate and resolution. Increasing the bandwidth to 128 kbps increases the frame rate, but you should have at least 1 megabit-per-second (mbit) connection for complex graphics at reduced quality or simple images in full color.

    A very fast 100mbit connection provides a seamless user experience. You can access another computer just as if you were sitting in front of it.

Latency

  • Latency refers to the delay in communication between two devices. Even if you have a high-bandwidth connection, you may experience slow performance in VNC if you are far away from the computer you wish to access. This is mainly an issue for users thousands of miles apart. VNC lists no specific latency requirements, but you should use an Internet connection with the lowest latency possible. Avoid cellular data or satellite Internet, which typically have very high latencies.

Network Usage

  • You should also take network usage into account. If you share a connection with multiple users or are downloading files while using VNC, performance will suffer. Make sure you are the only user on the network and that VNC is the only program accessing the Internet for a better user experience.
