Do Multiple Monitors Use More RAM? (Answered)

Since we all want to connect as many monitors as possible to the laptops and computers we have, it is often worth noting that you might be using more RAM. A common question on the internet from users is that the more monitors they connect to their PC, the more RAM they might use to run these monitors in many cases.

Fortunately, this is not the case and from what we have seen, you will not be using more RAM when you are connecting more monitors. RAM would be affected by internal things like how many tabs you have open and how often you are using certain applications on your monitor for performance.

What Affects RAM?

RAM or Random Access Memory is one of the most important elements of your computer and each computer or laptop would have a set limit of RAM, which could be used for the display of certain applications and to run certain programs.

If your computer is running programs, which are not compatible, it might require plenty of memory to run these and this would make the computer slow. It could freeze and send you a low-memory warning at the same time. 

Another big issue when it comes to RAM is the possibility of dealing with malware. If you are dealing with malware, you could also have some issues when it comes to RAM and this would slow down the laptop or computer significantly.

The downside is that malware would be hard to detect and you might need a good antivirus to ensure that you are dealing with the RAM effectively.

Can RAM Affect Your Monitor?

Unfortunately, RAM will affect your monitor in numerous ways and this would often be on the external display. If your computer is lagging or when programs are running slow, it would often causes a freeze. The freeze is detectable on the monitor and you will notice that certain applications will not respond as they should.

If you are running multiple monitors and you have different tabs open on each of these monitors by treating them as separate computers, it might use up more of the RAM than your computer has. Since you are running so many different programs, you might lose count and this is one of the best ways to see your RAM usage skyrocket.


RAM should not be directly affected by your different monitors and it might be frustrating for you to figure out how to deal with high RAM usage. Many people might blame the numerous monitors, but we have not seen any real conclusive evidence of this being possible. Let us know in the comment section if you have figured out how to deal with high RAM on your PC.
