Bests & Worsts Reviews from Amazon

I bought this monitor in Oct 2010 and it worked fine for 1 year. It is supposed to have a 3 year warranty. Then the display from the VGA input on my ViewSonic 2450 WM - LED monitor changed and suddenly was not allowing me to view the highest resolutions that it used to be able to handle. I tried it on 3 different computers, and had the same problem, so it was not an issue with the video cards (2 were a laptop, 1 was a desktop). I have a 2nd monitor of same type - and it worked fine on these 3 computers. I contacted customer service, and after deciding it wasn't my video card that was a problem (took 45 minutes of discussion), they had me send it in on my dime. 6 weeks later, I got it returned to me - and alas, it was not fixed. I contacted customer service again and the agent I spoke with for 50 minutes adamantly declared it was my video card even though I have the same monitor that works and the damaged one does not. He said I needed to contact the manufacturers of my video card and download updates. When I questioned what had been done to the monitor that I sent in, he could not provide any description of any warranty work that Viewsonic performed - just that the monitor arrived and then was shipped back out. He also would not allow me to send the monitor back in so that it could be replaced - arguing still that it was a video card issue even though the a 2nd copy of the same monitor works fine on these 3 computers. I finally gave up - not worth another hour long phone call with another agent, and sending it back into the service center when they don't even have policies to monitor what service work was performed. ViewSonic - you make nice shiny monitors, but your customer service sucks - quit trying to pass the buck on your customers and realize when you have need to replace a broken product.
