1080p Tv
1080p HDTV
You may know that 1080i refers to 1080 lines of vertical resolution interlaced. This means that instead of 30 frames a second, the TV displays 60 fields per second, where each field contains alternate lines of the picture. Because the fields are refreshed so quickly, your brain interprets the signal as 30 full frames per second.
720p means 720 vertical lines of progressive scan video where every frame of the signal is displayed in its entirety, giving a higher-quality, film-like appearance to the picture.
Most HDTVs or HDTV-ready TVs support either 720p or both 1080i and 720p, very few support 1080p HDTV. Part of the reason for this is that very few broadcasters want to broadcast 1080p signals. The reason for that is that 1080p requires significantly higher bandwidth than either 1080i or 720p. And for broadcasters, bandwidth is a precious commodity. Using up more bandwidth for one signal means that there is less room for other channels. So in many cases, opting for a 1080p signal would mean dropping or degrading other channels.
Is 1080p HDTV important? Well, yes and no. Not all video footage benefits greatly from progressive scan. Sports broadcasts and action movies look better at 720p than 1080i because there is lots of fast movement and the interlacing in 1080i is sometimes noticeable, reducing the quality of the picture. Movies and TV shows where there is not a great deal of fast action look better at 1080i than 720p because the higher resolution has a greater impact on quality than the progressive scan, which has little effect where there is only a small difference in the image between frames.
So, while 1080p HDTV is the best of both worlds, the cost in terms of bandwidth, is very high compared to the benefit for most people most of the time.
How does a PS3 blu-ray player compare to other blu-ray players?
I have a new 3D LED TV, it came with a blu-ray player but I'm not sure if I should use it or just use my PS3. I have a monster HDMI cable capable of transmitting 3D content hooked up to my PS3 but the picture quality on my TV is really good, but not great. Anyone think the blu-ray player it came with will work better?? (and and the TV and player are LG)
I've been told it doesn't matter what blu-ray palyer you use, as long as there is a good HDMI cable hooked up you are fine, but is this true? I mean there are a lot of LED 1080p TV's out there (same stats and stuff) but the picture quality may be better or worse than others. Does the same go for blu-ray players?

Xbox 360: MW3 won't run in 1080p, only 1080i, is it because I need HDMI?
We just got a new flatscreen that is 1080p compatible. It's hooked up to our receiver via component cables (red, green, blue). It powers on fine and when I select 1080p in the settings everything looks great on the dashboard. But when I run the game MW3 it switches over to 1080i, and the gameplay quality isn't really that great (probably cuz it's 1080i on a 1080p tv). But the weirdest part is when you hit the xbox button the guide pops up briefly and the screen goes black with a series of clicking noises. Then the tv says "no signal." If you hit the xbox button again the guide closes and you can see the MW3 screen again. I'm no expert, but I think this is because the guide runs in 1080p and the game MW3 runs in 1080i so when they are both up at once the xbox gets confused and the signal goes out or whatever. But MW3 should be running in 1080p!!! Because the back of the MW3 box says that it can! By process of elimination, I guess this happens because I'm using component cables instead of a HDMI cable. Will HDMI solve this?
