My old Pioneer plasma that now lives in a closet covered in a blanket had a lot of video inputs. Component and VGA inputs were casualties of my recent upgrade to OLED. Time marches on, unless you still want to play old game consoles or accidentally slip and fall and become frozen in a crevasse. Then, assuming you fall into the former and not the frozen category, you need to decide if composite video is sufficient for your fully-thawed, unconventional, yet not uncouth tastes.
For me, composite would not do, partly because I realized my new TV was capable of it only after I finished the project I will be explaining in excruciating detail. This fact aside, in order to get the best picture out of the old games I always plan to play but rarely do, I learned I would need to embark on a potentially never-ending-always-spending project. → Mr. Gorbachev, tear down this post!
