I just bought a 4900 and the picture IS HORRIBLE. Gave me a headache watching an NFL Game on ESPN. I bought this for the PVR Function, the MAGBOX had no such issues when connected to the same services and channels. My Internet Service is 400 MBPS UP and Down before someone goes there first and its verifiable via wifi on my phone and tablet. Also not using a VPN
The jittering during action scenes is intolerable. All help is appreciated.
