Businesses must ensure their remote workers have access to a remote desktop and are equipped with the right technology to perform their jobs effectively. That definitely includes screen-sharing tools powered by virtual network computing<\/a> (VNC), which enable seamless communication and collaboration. But what exactly is remote VNC screen sharing, and how can it help your business? In this guide, we’ll explain how VNC screen sharing works, what it can do for your teams, and how to set it up.<\/p>

What is screen sharing?<\/h2>

At its simplest, screen sharing is the ability to share what is appearing on the screen of one device with one or more other devices. It can be a useful tool for collaborative working, online learning<\/a>, or video conferencing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

As the chart illustrates, employees spend a notable portion of their workday collaborating, both in person and virtually, reinforcing the importance of tools like VNC screen sharing in enabling real-time, digital teamwork.<\/p>

Remote desktop collaboration in action<\/h3>

For example, if one of your team was working on a sales forecast for the coming year, rather than sending the results of the work to other team members, they could participate in a conference call and share the results on other participants’ screens. This would enable your team to have an active discussion and ask questions about the data.<\/p>

While some screen-sharing applications act differently from remote access technology<\/a> and do not let viewers control the remote keyboard and mouse, RealVNC’s screen-sharing services offer a range of solutions to suit all users. As well as viewing remote screens, RealVNC users can access and remotely control systems. However, in this article, we’ll be focusing on screen sharing for remote viewing only, particularly using the VNC protocol.<\/p>

What is VNC screen sharing?<\/h2>

VNC stands for Virtual Network Computing, a cross-platform remote-control technology for reaching one computer’s desktop from another. It was created in Cambridge in the late 1990s by RealVNC’s founders, working at the Olivetti & Oracle Research Laboratory. It works on a client\/server model: a server component runs on the computer being shared, and a viewer connects to it from another device. The two communicate over RFB (Remote Frame Buffer), the protocol that governs how screen data, keyboard input, and mouse movement pass between them.<\/p>

How virtual network computing works<\/h3>

Because RFB works at the level of the display rather than the operating system, VNC runs on Windows, Mac, Linux, and Raspberry Pi alike. That makes it a practical option for remote access across mixed environments, whether you’re sharing your screen with a colleague or giving support staff control of a machine to troubleshoot it.<\/p>

What are the benefits of remote screen sharing?<\/h2>

Before you purchase VNC software or sign up to a service that enables screen sharing, you want to have a comprehensive idea of the benefits that remote screen sharing will bring to your business. Knowing the advantages of screen sharing means that any decision to move forward with this technology will be an informed one.<\/p>

\"Team<\/p>

1. Better collaboration and productivity<\/h3>

If you have any staff that work remotely, you will want to promote better collaboration and boost productivity.<\/p>

Sending a file to other team members is a static snapshot of the work they’re doing and doesn’t foster a high degree of collaboration. Screen sharing allows your teams to solve problems together in real-time and can help improve productivity rates.<\/p>

For example, let’s say some of your marketing team is working in different locations. The lead on your new campaign wants to share their ideas. Using screen sharing, they can make changes as other members of the team suggest them. This can save you both time and money.<\/p>

2. Online learning<\/h3>

Career development plays a major role in most organizations. Of course, in-person learning poses logistical and financial problems. Screen sharing makes the world a smaller place and lets anybody that can see the remote desktop screen being used by the learning provider participate in a session.<\/p>

Participants can ask questions in real-time while the provider shares information from their device. Screen sharing can help streamline the learning process as well as save your business time and money. There are no travel or accommodation costs associated with the learning, as staff can join from wherever they’re located.<\/p>

3. Better client\/customer service<\/h3>

As with your staff, clients can be located anywhere. Therefore, sharing ideas and information with them can be fraught with problems if \u201ctraditional\u201d methods are used.<\/p>

Remote screen sharing simplifies sharing information with them and allows you to incorporate their own thoughts and ideas.<\/p>

This is another benefit that can save both time and money. Rather than playing \u201cping-pong\u201d with emails to get to a final decision, an agreement can potentially be reached with just one video conference.<\/p>

By sharing your ideas or products using a remote link, you are also empowering your clients to make better decisions.<\/p>

\"Customer<\/p>

4. Customer support<\/h3>

You will know that customers sometimes experience issues. They may not understand certain functions of a software product or struggle with certain aspects of one of your tools or applications (or even with your own website).<\/p>

Screen sharing allows your support staff to see what the customer is struggling with and diagnose any issues quickly.<\/p>

For example, say a customer recently bought a SaaS product from you but is not able to set up certain features. Through screen sharing, one of your staff can see what the problem is and guide them to a successful solution. In comparison, verbal guidance over a phone call can take a much longer time.<\/p>

Challenges of screen sharing<\/h2>

As with any new tool or process, screen sharing can present some challenges, especially in the initial period of implementation. Knowing in advance what those challenges are can prepare you, allowing you to mitigate or deal with them swiftly and easily.<\/p>

1. Frozen screens<\/h3>

This can be a common problem during screen sharing. It’s usually caused by either a slow connection or insufficient bandwidth.<\/p>

You should ensure that all screen-sharing participants have sufficient bandwidth, as well as a stable and strong internet connection. Something else that can cause this problem is other programs or applications using up bandwidth. Participants should close any unnecessary programs to help avoid this.<\/p>

2. Audio issues<\/h3>

Seeing information is all very good, but if you can’t hear what the presenter is saying \u2014 or discuss pertinent points \u2014 then the process is inefficient.<\/p>

Audio issues can happen due to low-quality microphones, poor-quality sound cards, or outdated audio drivers. You should have an audio test prior to any screen-sharing sessions to ensure that all components are up-to-date and working correctly.<\/p>

3. Color<\/h3>

Another problem that may arise due to outdated drivers or related issues is poor color visibility on the shared screen. This could range from distortion to saturation, either of which can detract from the session’s quality.<\/p>

As with audio issues, you should check all drivers are up to date. You can also check that the color profiles on all participants’ computers match up.<\/p>

4. Flickering screen<\/h3>

There’s little worse than a screen that is constantly flickering during a screen-sharing session.<\/p>

While this is another issue that may be caused by a poor connection or insufficient bandwidth, it can be due to some other factors. One major cause can be participants using different versions of the screen-sharing software. Make sure everyone in your team has the latest version of the software installed on their devices.<\/p>

How to set up screen sharing<\/h2>

Before diving into the details, it\u2019s useful to understand the basic setup process. Screen sharing typically involves:<\/p>
