Thanks for the reply. The model number of my Samsung tv is UN55EH6000. I will look into the remote timer option because, as you stated, the digital QAM modulators are just too expensive. Also, since HD is a must for this project, I won't be able to use the cheaper solutions.
Worst case scenario I will return the Samsung, take the hit on the restocking fee, and get a pro signage monitor. I found a 55" LG for around $1300 which is around the same price as the Samsung- It just doesn't look as nice.
I appreciate you taking the time to answer my question!
