Dell never sold this monitor with a 5 year warranty. The standard 3 year warranty expired either on February 28, 2020 or 3 years from your purchase date. [IMAGE] Read this.
I bought U2417H at Best Denki in Singapore in 2017.  It recently displayed a green vertical line on screen.  As I have moved to Hong Kong, Dell HK support team reverted that the warranty was under Singapore only and so replacement could not be done in Hong Kong.  The service tag was shown “invalid” when inputting it on Dell site, and so warranty check and transfer could not be proceeded.  Please help me understand why the tag was invalid, and advise how the warranty can be transferred to Hong Kong, and replacement be done. Thanks!
