we just bought a 39lb5820 last saturday @ 26k abenson fairview terraces. before buying, i knew this was new model and with wifi network connection, so i had the salesperson demo'd it to us since ok na yung feature/price na yun saken. what i didn't know, and what the salesman said was na 120hz na yun. i was doubtful na 120hz kaya sabi ko na prove it, kahit na sense ko na very knowledgeable sya technically sa features ng mga tvs. right beside the demo 39lb5820 was another lg a bit bigger, parang xxlb62xx model, so he played the demo disc na fast moving on both tv same time, yung water rafting sa canyon scene. definitely the lb5820 was much much smoother than the other one. yung isa daw is 60hz kasi, very evident dun sa canyon walls close up and moving nag la-lag/stutter, while sa lb5820 smooth. i said to wifey na yung lb5820 na kunin namin kasi 120hz and tried to explain pero of course di na maintindihan, thats when we showed her again the demo scene and pointing the the difference sa lag, and she did notice them.
