1080 to 720 Question

post #1 of 7
Thread Starter 
I have Verizon FIOS and a 42 inch Sharp Aquos. Everything was running fine with the AV cables at 1080. I finally had an available HDMI slot open for the TV since I sold my XBox. When I plugged the FIOS box in as HDMI all my HD channels now say 720.

Didn't I just lose quality? How can I fix this? I'm not really sure why that happened.

1080i or 1080p ?

1080i is rather close to 720p in a manner of speaking. With games 720 is better because of of progressive ability and games having a higher frame rate. Will you notice the difference in 1080i and 720 ? I highly doubt it.

Only HDMI can handle 1080p. HDMI supports all HD resolutions.

TV isn't broadcast in 1080p (some satelite providers have 1080p on demand though).

The highest resolution you'll see is 1080i (1366x768) or 720p (1280x720)
Difference there is between the resolution and if the image is progressive scan (p) or interlaced (i).

When you plug in your Xbox the TV will default to 1080p because that's what the Xbox will display at optimally.
Subsequently, the resolution will change from game to game depending on what it's upscaled to.

Aha! Excellent. Now I understand. So, the HDMI cable didn't lower my resolution. It is weird because with the AV Cables it always read 1080i and now it's displaying 720p with the HDMI cable in.

In the box settings you can add/remove res. that can be shown. Component cables can run up to 1080i but still can run 720p. Most of the boxes support up to 1080i, but 720p is better IMO. Progressive Scan is definitely better than interlaced.

1080i is NOT above 720p. 720p has the better picture because 1080i is only 540 lines interlaced.

Some OTA are broadcast at 1080p x 24 Hz.
