I thought about 4k vs. just a full HD tv when I bought my Samsung last year, kasi ang ganda ng picture quality na ipinakita sa akin, but I asked so many questions sa store rep at kung ano na ang available channels at tv programs sa pinas capable of handling 4k. In the end, I bought full-HD na lang, since hindi pa fully ready ang 4k technology, hindi pa mainstream. I didn't regret my decision.
