Whether you want to upgrade your monitor or want to set up your entertainment system, to make sure you get the right DisplayPort cable for your projector screen, here are a few things you must consider before purchasing

Specifications

Every technological device has specifications for the function it performs. When talking about data transmission and networking, these days there are many devices available with different specifications. 

Talking about DisplayPort Cable, the higher the speed and resolution, the better the picture. There are mainly two types of DisplayPort cables: the standard cable (the most commonly used) and the Mini DisplayPort (ideal for smaller devices).  

Connectors 

When choosing a DisplayPort cable, one must check the connector type. There are mainly three types, including, USB Type-C with DP ALT Mode, Standard DisplayPort, and Mini DisplayPort. 

Besides, opt for cables with gold-plated connectors, as they are corrosion-resistant. They also offer stable connections with no risk of signal loss. 

Certification

Understanding certification is very important when choosing a DisplayPort cable. These cables are primarily categorized by their bandwidth certification level. Certified cables support high bit rates and are constructed to provide nothing but the best performance. 

For instance, it can support four displays on a single cable. On the other hand, poor quality, old, or non-certified cables can cause audio/video corruption, data errors, and more issues. 

Quality

When purchasing a display port cable, always avoid the ones with low quality. You wouldn't want unexpected audio or video problems. On the other hand, high-quality DisplayPort cables not only offer smooth performance but also durability. 

Talking about a good quality cable, it comes with better shielding, and thickness and is more robust. As a result, it will be less prone to damage. Therefore, when purchasing, opt for reputed and trustworthy brands only.

Version 

The version of the DisplayPort cable also plays a major role. It comes in different versions, such as 1.1, 1.2, 1.3, and 1.4. Because each version has its own features, it is important to choose the one that fits your requirements. 

It is advisable to choose a cable with the latest version, as older ones may lead to poor and limited performance. Besides, when purchasing, one must make sure to purchase the right version as per their equipment requirements.  

Length 

When choosing a DisplayPort cable, you must keep length in mind. Because they come in various lengths, from feet to meters, choose a cable that will meet your needs. Some of the most common lengths of DisplayPort cable are 1m, 2 m, and 3m. For instance, to minimize signal degradation, you can opt for the shortest cable length, but for longer distances, choose cables with longer cables. 

However, with long cables, make sure they are of high quality to maintain signal integrity. Besides, keep in mind, that if you don't require a long cable and need a short one, then make sure it has enough space to move to avoid mishaps, wear and tear, and damage. To help you understand better, here are some tips when choosing the length:

• For a shorter distance, opt for a high-quality cable with a 32.4 Mbps capacity. This will ensure you the finest performance. 
• For longer distances, use a lower bandwidth cable.
• For a higher-resolution display, purchase a high bandwidth cable. This will prevent issues with image quality. 
• To make sure the cable functions properly, verify that the connectors on the cable match with those on your computer and monitor. 

Resolution and Refresh Rate

Another thing to consider when choosing a DisplayPort cable is its maximum resolution and refresh rate. Because different cables have different features, make sure you choose a cable that will support your requirement for the projector screen. With the right supported cable, you can enjoy high-resolution graphics and smooth video. 

For instance, it can support resolutions up to 8K at 60Hz and 4K at 120Hz. But do you know higher video resolutions and refresh rates require more bandwidth with every DisplayPort standard update? Yes to help you understand better, below is a table:
