Hi AD Adicts! Let me get straight to the point. I have a 50 inch LG plasma tv model 50PC3D. Its 720p. I usually watch digital cable on it. I have the signal coming from my digital cable box or operating box, whatever u want to call it, using a digital cable, or the RF cable is what its called I beleive. Now, recently it just clicked to me that maybe I could have a better quality picture on my tv if I purchased an HDMI cable that would connect from my cable box to my tv instead of the digital cable.. Can anyone tell me if thats possible? The back of the box looks exactly like this.
