Watching this thread i'm just wondering how many people actually know the meaning of the "p" in 1080p, 720p or the "i" in 1080i, etc.

For example most would say that any 720p tv has the same quiality as any 1080i tv. (and yes they make 720p tv's, they are called "enhanced definiton") For example; 720 lines of resolution in a progressive (p) refresh rate (line 1,2,3,4,etc in order all the way to 720) has the same quality as 1,080 lines of interlaced ( line 1,3,2,5,4,7, etc all the way to 1,080) refresh rate. The 1,080 lines of interlacing take about the same time to refresh as the 720 lines of progressive scan do. Concluding, the the picture will be about the same. The problem is when you step up to 1,080 lines of progressive scanning lines. Movies will not have a problem getting to this stage of refresh rate sometime soon, but in the gaming world, you wont see 1080p for a while. No system can support the refresh rate of 1,080p. It would cause way too much lag and bogg any system down.
