LCD's have pixels, not scan lines... so 1080i (i = interlaced) cannot be displayed on an LCD.

If your TV says 1080i (which both of mine do when a 1080i source is being used) this simply means it's taking a 1080i signal and displaying it in whatever progressive scan format it wants to... generally 720p.

 

I see. I was only reading the 'input compatability'. Didn't realize it was being processed to 720p.

 

My LCD does 1080p

 

jaws, 1080p is good

 

Good, thats better obviously... but 1080i will downscale to 720p, or it could upscale to 1080p, but you wont see any improvement in quality.

"upscaling" is kind of a joke... you cant improve picture quality... if the picture information isn't there, it isn't there.

 

i always thought upscaling was a scam too but i picked up a phillips upconverting dvd player for real cheap cause my old one died. I ran my high end component cable out from it to my lcd and the picture was ok. So I decided to connect using my HDMI cable (that was for my shaw pvr) to it for a comparison. The dvd player automatically "upscales" when the HDMI cable is connected. So I compare the same dvd movie with the component cable and the HDMI cable and I could actually see the difference in the color and sharpness. Like I said I always thought this upscaling was a gimmick but it made enough difference for me to go buy another HDMI cable.
