Default 1080p output on 720p display

I have a vizio 37in 720p television. i love it and think the picture quality is great. My previous upconversion dvd player and Insignia blu-ray player have only allowed me to outup up to 1080i video. and the input on my tv always showed accordingly 720p or 1080i. I recently got a new Sony BDP-S370 bluray player and was playing witht he audio and video settings, it will allow me to output 1080p, and my display now shows 1080p on its information. As far as I know my TV will only display the 720p or 1080i. Is it better or worse for my bluray player to output in 1080p or should I have it output in 1080i or 720p? Thanks!

Doesn't matter, your TV can only show what its resolution will allow.

Exactly your tv is showing the INCOMING signal resolution , no matter what what is on your screen is 720p (your tv converts it to the native display)

No matter what kinda shit you feed the TV, its gonna stretch to 37" and display at 720p. SD of course will look far worse because the pixels arent there to be displayed, so its upconverted the best way the tv knows how, while 720p and 1080p will be displayed in 720p.

Rule of thumb, in most cases, feed the tv the highest resolution source possible.

Usually sets that are not a perfect 720p, which is 1280x720, will display a better picture when displayed 1080i/p instead of 720p.

For example, A 720p Panasonic plasma is actually 1024x768. (also, some 720p LCDs are 1366x768) In this case, is always looks better to send the unit 1080p, or 1920x1080, then 720p 1280x720. The down coversion of 1080 across the 768 lines looks better then the upconversion of 720 across the 768 lines. This is simple to understand, as scaling the higher resolution down, ensures the set can use all 768 lines as best it can.

If in fact your 720p tv is actually 1280x720(which is rare), then feeding the set 720p will most likely look the same as feeding it anything higher.

Since your 720p "class" TV is actually 1366x768p it will display all resolutions as that resolution because that is the Native (only possible resolution it can display) regardless of the incoming resolution.

For BD player output it should be at 1080p for the best PQ possible with the least conversions, since as previously pointed out, 720p is actually 1280x720, and with your 1366x768p display it would have to first have the BD player reduce the output to 1280x720 and then the display would have to guess what pixels to add to get at the native 1366x768 resolution it displays. By sending 1920x1080p it only has to do one conversion with no huesswork at what to add by adding back pixels that it doesn't get.
