1080i and 720p are effectively the same.
:facepalm: really? again?
1080 i and 720p are not only 2 different resolutions, they are ALSO two different ways of the image being sent to your screen. They are COMPLETELY different.
When someone tells you, 720p is 1080i, they are talking about the image being upscaled. But that is NOT exclusive to all 1080i resolutions. As I just explained the ONLY way for GTA 4 to upscale, is to upscale to 1080 P
1080 P GTA 4 up-scales from 720p to 1080
P. But that does NOT mean all 1080p resolutions are "effectively" just 720p. Just as 1080i is not "effectively" 720p.
Is this making sense to you yet?
A specific game upscaling a lower resoltuion to a higher res on on your TV, does
not makes those 2 resolutions universally the same.
If I display something in 1080i on my flatscreen, that SUPPORTS 1080i. it is in fact DISPLAYING in the proper 1920 by 1080 resolution and sending the image to my screen INTERLACED. not some upscaled 720 resolution. Its only upscaled when what I'm viewing does not support 1080i. But Skyrim claims to support 1080i... Unscaled or not, it claims to support it.
Just as Final Fantasy 13 on PS3 was "1080p", and would run as such, but the native resolution of the game was actually 720p, with the game upscaled. Whether it's an "i" or a "p" following the resolution is not what decides if its upscaled or not. Mkay?
Does this makes sense yet, or do I need to explain the same thing in a different way?
