Suppose i'd like to pick a 4k samsung tv that can match 60fps, any suggestions?
Because if i read correctly their 100hz tvs are native 50 hz
50Hz is merely a PAL TV signal compatibility mode and 100Hz it's frame-interpolation. I'm not aware of any TVs released in the last decade that don't support 60Hz input/output natively. Even my first 768p super low cost LCD TV did so in 2007.
