The TV supports 1080, but I found the solution by hot swapping the unit after booting with the computer monitor. This boot up set the output to the monitors resolution. Once attached to the Television I had a clear and steady picture. Using the video set-up in the Retropie menu I set it up to use the monitors default resolution. I then shut down and rebooted, and the system loaded to the retropie config I had just corrected. Going back into the Retropie menu's video set-up, I was now given the option to change the resolution to television, progressive, at 720, which is where I wanted this to run to allow for portability. I saved and rebooted and the system loaded on the next try. Four reboots later the system is still easily displayed.
