my friend said there is no difference but hes not the smartest so i was just wondering if there is any difference
1080i vs 1080p on 360 games
This topic is locked from further discussion.
ya one is 30fps (1080i) the other is 60fps (1080p) image quality is identical. Regardless to whoever tells you otherwise. 1080p/i - 1920x1080 ... its just like a resolution on your computer monitor. So think of it this way. You can have a refresh rate of 60MHz or 30MHz. Unless your playing something that is intense intense action (lots and lots of explosions) even a game like halo 3 looks fine in 1080i and if rendered in 1080p its still the EXACT SAME RESOLUTION its just a faster refresh rate of the screen allowing for more fluid looking animation... im so sick of people saying there is an image difference between 1080i and 1080p .... go to your computer monitor. Play a game at 30fps and then at 60fps ... it looks identical. It just doesnt refresh as fast.ColdfireTrilogyyour very wrong, 1080i is actually half of the resolution. it shows a screen resolution is has half as many lines on the screen and one frame it shows all the even lines, and the next it shows all the odd line. this is what sdtvs did and when images are still it looks like a sharper resolution than it is. when ur playing games the difference is noticable due to the interlacing is not able to show u the animation properly when the screen moves and updates fast. this video explains all REALLY WELL http://www.youtube.com/watch?v=Z-JXfyvlPh0 the fact is out of all the hd video modes 1080i is the worst mode, 720p is the 2nd best, and 1080p is the best. 1080i is actually a lower resolution than 720p. the difference between i & p resolutions inst frame rate, its thats one picture is interlaced (1 screen shows odd lines then next shows even) and the other is progessive (full picture on the screen the whole time every frame) watch the video and you will see your wrong this picture explains a bit also to see how the 2 pictures make one on interlaced tv modes
if you look at that picture you will see theres only 540 lines on the screen on 1080i, but with 720p theres 720 lines, this allows for more detail and better quality animation when its displayed on ur screen. if you have a plasma or lcd tv you should always use the progressive resolutions for best possible picture, these are progressive screens, if you use interlaced pictures on them then they will never look as good, crt monitors and sdtvs tend to be interlaced and the glass screen usually has a filter to take away the effect, but interlaced on a progressive screen shows up the interlacing rememeber 1st 1080p, 2nd 720p, 3rd 1080i use the best one ur tv supports. if it has a screen resolution of 1900 x 1080 then use 1080p, if it has anything below that then use 720p just because 1080i has bigger numbers in the name does not mean its a better picture than 720p although the numbers are misleading,, its simply not true, and 1080i is not even close to being the same as 1080p. the p & i is not the refresh rate, its the rending mode of the tv, your tv's refresh rate is independant of redering mode
