One of the things that may hold you back from using an old monitor for gaming, photography, graphics editing, or some other visual purpose is that it’s not displaying the kind of vibrant color you want or will find in a new monitor.
There are different reasons that may be the case, ranging from your software settings to the hardware you are using. The good news is that most old monitors whose colors look washed out or inaccurate can be corrected to look a whole lot more colorful and vibrant.
