Monitors are different, some are light, and some are pretty heavy. Before buying a triple monitor stand, make sure each arm is strong enough to hold your screens. Most manufacturers specify this, so don’t forget to check this information before making a final decision. You don’t want to end up with a nice-looking monitor desk mount that might break in a matter of seconds under the weight of your multiple screen setup. However, if you’re not sure you can measure and weigh your screen accurately, you can find the specs of almost every monitor ever made using the vast database of Ergotron’s Mount Finder.
