I was playing Destiny online yesterday night with a couple of friends and the matches annoying. Aside from connections, there was something really strange going on: one of those two friends of mine was playing with my "same" connection, meaning we have the same ISP subscription (so same network download & upload speed), same router and we live in the same building (so we're equally far from the nearest ISP's network node). We even have the same router's ports opened, but every time we were having hard times in game, he was receiving game images one second or so before me.
The only thing that differs is the TV: I have a 40" Samsung Full-HD and he has a 50" Hisense LTDN50K680XWSEU3D. So I remembered about frame rate, Hz and response time and googled everything. I found that TVs with higher Hz are better cause they show smoother images BUT the human eye only detects changes about every 1/25th second (so it's near 80Hz).
After this long premise, my question is simple: what's the best Hz amount for a perfect gaming experience? My friend's Hisense TV has 400Hz and a response time of 6.5ms. I think that something like 100Hz and 20ms of response time would be perfect for console gaming but I'm not sure.
