LOL. The most important spec in regards to picture quality is Dynamic Contrast Ratio. I take that back. If you have a huge screen (like 50"+), then it's the resolution. The most useless spec is the 240Hz. Once you get to 120Hz, I feel the extra is BS, especially for POS brands.
not exactly true
The motion interpolation systems can vary in quality by brand...just like their picture quality
Unless you are looking at a Samsung or Sony then what you are looking at is not true 240hz
Vizio, LG and Toshiba( and possibly others) use a simulated 240hz by putting a scanning backlight in a 120hz panel
