There are advantages to each! New monitors have the longest life ahead of them, are free from any wear and tear or cosmetic blemishes, often have better quality display, and have a 1-year manufacturer's warranty. But, they also have a higher price tag.
Used monitors are a great budget-minded alternative. Quietech thoroughly cleans and tests all our used monitors for quality. The downside for refurbished monitors is the lack of a year warranty from the manufacturer, and a potentially shorter lifespan.
As you can see, there are pros and cons to each choice. Reach out if you'd like help with the decision!
