I just installed a new 27" LGE monitor, with the CD's drivers, on my computer and now Amazon Prime Videos won't run. I was previously using a 19" Dell Monitor that had no problems with Amazon Videos. Now I am getting a message on Amazon that says: "Unsupported Operating System Amazon Video titles can't be watched on this device because the operating system isn't supported. For more information, please see Amazon Video system requirements." I understand XP is supposedly not supported, but it WAS before I installed the new monitor. Is the problem with the new drivers? I don't have any problems with Netflix, YouTube, etc. I tried it on both Firefox and Chrome and get the same problem with both browsers. It doesn't make sense to me. The Display settings in Control Panel show: Resolution 1920x1080; LG IPSFULL(analog) on Radeon x85 Series; 32bit highest. My system is :Dell Dimension XPS, Pentium(R) 4 CPU 3.60 GHz; 144 GB HD with 52GB free; 3.00 GB RAM; MS Windows XP Media Center Edition Ver2002 SP3 Can someone help or suggest a solution, besides buying a new system? Thanks
