720p or 1080i for blu ray

[admin_exported]

I have a 42 inch Panasonic plasma which is 1080i, 720p. When playing blu ray discs is it better to be on 720p or 1080i?

Which model number is your Panasonic? If it's a more modern one, it'll accept a 108p/24fps feed from your Blu-ray player and optimise it to suit the screen. let me know and i'll let you know!

Hi Clare - I was wondering the same thing initially (Pioneer 427XD) and I found out it does accept the 1080p/24 signal, but what I can't fathom is what happens when the disc isn't playing....because if the Blu-ray player is set to 1080p but it reverts to a 50hz (25fps) signal when a disc isn't playing (I'm assuming that it would) then the TV can't handle that, so presumably the screen would be blank! Any ideas?

If this is a really stupid question then please take pity on me and explain.....

There isn't a TV screen sold in the UK that couldn't handle 50Hz as this is the standard refresh rate for the PAL signal i.e. all TV broadcasts and standard DVD replay. So no need to worry on that front - 24fps is the odd one out here, so it might well make special mention it can accept this signal, but a 50Hz (or 25fps) signal is a given with UK TVs.

No question of doubt for me, a 720p progressive scan picture produces far better results than a 1080i interlaced one.

Professorhat (or anyone!) - the HD ready Pioneer 427xd that I've got will accept a 1080P signal only at 24fps. Bizarre I know, but true. Obviously every other type of signal (480i/p, 576i/p, 720p, 1080i) will work at 50 or 60 hz as you'd expect. Hopefully my original question makes more sense now. I realise that I should have explained this properly in the first place!
