I happened to notice a few days ago with a Bell #9242 receiver and a Samsung LN46C650 LCD TV which can indicate on the screen the Bell 1280/720P output information, that during the Bell 3AM software download it changed to 1920/1080i for a few seconds.
Anyone have a reason why this would evolve?
Thanks.

Nope. Never stayed up to watch that event......

I have the exact same tv with the 6131 receiver. I have just been a Bell customer for 2 months. So far, it has always displayed as 1080i.

funpig , the setting should be set by you to 720P with the Bell #6131 remote.
This is done by clicking Menu, System Setup, HDTV Setup, TV Type - 720P, Aspect Ratio 16x9 and then Done.

It would appear from my opening post that Bell may be using 1080i for some of their transmissions. This is only speculation on my part and not confirmed.

I know from my other location in Florida that Dishnetwork transmits some of the time in 1080P (same as Blu-Ray) for their PPV movies.

I think it was CTV that was the last Channel to be at 1080i and that was changed to 720p quite some time ago.

To the very best of my knowledge there is absolutly nothing at 1080i right now from Bell TV.

Some people leave their HD Receivers at 1080i some change them to 720p, all I can suggest is try them both and choose which you yourself prefer.

Transformation.
Take a family picture with a digital camera at 1 MegaPixel, reduce it's size to 1/2 the original in Photoshop at 300dpi, then send it to a special company who will print it on a 4 feet high banner. Result should be deeply deceiving.

Same for Television. Source comes from 1920x1080, reduced by Bell Headquarters to 1280x720p and 60 images per second and uplink to the satellite. If you set your terminal to convert to 1080i, the terminal will then stretch the screen (540 pixels more x 360 pixels more) and send out 30 images per second.
If your TV is native 1080p, it will then try to convert interlace to progressive, missing 30 images per second.
If your TV is native 720p (displays 768 lines), it will downconvert to 720 and convert interlace to progressive... so the terminal did stretch the screen for nothing.

Since all channels are 720p on BellTV, isn't it a better idea to set the output to 720p on the terminal and let the TV do the work ?

It is all about perception.

At the end of the day, it is up to the person watching TV that must decide, not the technical data and math skills.
