Backward Compatibility is a function that allows users to use the older system with a new system of the same technology.
For example, with this function, you can use the newest charger of a mobile phone to charge the oldest mobile of the same brand or system.
Similarly, there are many versions of the DisplayPort interface; therefore, its users are often confused about whether their new system works with the old.
So, Are DisplayPorts Backward Compatible?
YES! All the DisplayPorts are Backward Compatible with their older versions. So, if you have a system that supports older DisplayPort and a cable or monitor of the newest DisplayPort, you can run it smoothly, or vice versa. Although, the performance you’ll get is of the oldest version of the system.
All the DisplayPort versions are designed to be compatible with one another. So your system will work fine if you have a DisplayPort 1.2 computer, a DisplayPort 1.4 cable, and a DisplayPort 2.0 Monitor.
But, there are a few things that you need to know that are discussed below.
Are All DisplayPort Cables Backwards Compatible?
Yes, all the DisplayPort cables are Backwards Compatible. So don’t worry if you have DisplayPort 2.0, 1.2, 1.4, or other versions. You can buy any latest version to run with your older port. As I already told each DisplayPort cable is made to support each other to have a great experience. Also, remember that most DisplayPorts are backward compatible up to 1.2.
Also, I want to add it is better to use a VESA Certified DP cable that supports every feature and gives users excellent satisfaction. You can check our other posts to learn about the DP Cables.
Are DisplayPort Cables Forward Compatible?
YES! all the DisplayPort Cables are also Forward Compatible. Your signal connection will go up with the oldest connection. So if you have an upgraded port, you can still use your older DisplayPort with almost identical functionality.
So thanks to modern-day technology and DisplayPort for making this user-friendly system.
Can You Use DisplayPort 1.4 with a 1.2 Monitor?
Yes! You can use your new DisplayPort 1.4 with your older 1.2 Monitor. There is no problem or performance loss in using this.
DP 1.4 is perfectly made to use with 1.2 ports, so you are in the safe zone to make a purchase and use it with your older system.
But, if you’re using a 1.1 or 1.0 port, you must ensure that that version supports the DisplayPort you’re buying.
But, to eliminate all these hesitation and compatibility confusion, one can use VESA Certified DisplayPort Cables because it supports almost everything.
These VESA DP Cables are certified to give buyers an excellent experience. So you don’t have to worry about anything.
So as a summary, I can suggest most of the DP cables after 1.4 are backward compatible. However, some 1.2 DP Cables also support the 1.0 and 1.1 versions, but you should check before buying them.
