Hey mredge11,

OK, I'm glad to hear you've tried some of the more basic steps like power cycling. Have you tried any of the following:

- Disconnecting all other video sources and attempting to replicate the behavior with over the air (OTA) TV

- Checking for a firmware update and trying the settings again: http://support-us.samsung.com/cyber/popup/iframe/pop_troubleshooting_fr.jsp?idx=168699&modelname=UN55ES6500F&modelcode=UN55ES6500FXZA

- Resetting the TV to factory deafults: http://www.samsung.com/us/support/supportOwnersHowToGuidePopup.do?howto_guide_seq=6790&prd_ia_cd=N0000058&map_seq=44746

Let me know if none of those work.

Regards,
