Got a 4k qs2721 monitor in 2020The monitor has failed and been replaced 5 times in the last three years for a few different issues. Dell sends out a refurbished unit as a replacement not a new monitor.Customer service/tech support outsourced to India (?). They speak english fine. There is a bit of static and sometimes loud background noises.This last claim was bad. They try to tell me the warranty expired in April 2023 when it goes until December 2023. Even after providing them with the info from the original monitor and the previous replacement they struggle to uncover the warranty coverage. Strange.It took 1.5 hours to resolve. I lost my cool. Waste of time. Product is Made in China.. garbage.Dell knows exactly what they are doing. Warranty claims are set up to be inefficient and nearly fraudulent. I didn't even know monitors could fail so often. I thought Dell was a quality name and the product would last well beyond 3 years. What a joke.
