Best combination of settings???

[Newfiestang50]

Hello Forum, I just purchased a new Sony SXRD 50", my question is, what is the best combination of settings between my DVD player, Rceiver, (Yamaha RXV-2600) and TV that will give me the the best results. Right now I have my Yamaha DVD player set to progressive, receiver set to upscale to 720P. Is this ok or should I change the DVD player to interlaced and upscale the receiver to 1080i. Any suggestions will be appreciated. Thanks.

There is no way to answer that question definitively other than try each option and see which you prefer.

The Sony SXRD has a native resolution of 1366 x 768 (768p) which is slightly higher than 720p and slightly lower than 1920 x 1080 (1080p). All HDTV scale the incoming signal to their native resolution.

So if you have the DVD player output progressive and the receiver upscale to 720p the TV will turn around and scale that further to 768p. If you have the DVD player output interlaced and have the receiver scale to 1080i, the TV will deinterlace (make progressive) the 1080i and then decimate the signal down to 768p or it will decimate the signal to 540i, deinterlace, and then scale to 768p (that's an implementation detail and who knows which approach they actually use). The point is that none of those resolutions match the native resolution of the TV so scaling is done multiple times by different devices.

You might be better off just letting the DVD player output 480p, the receiver do nothing, and let the TV do the scaling from 480p to 768p.

You'll have to try all the combinations and see if you can actually tell a difference between any of them.

Actually my SXRD has a native resolution of 1080p, so you saying that if I just let the DVD player output 480p the TV will upscale to 1080p. If that is the case than I am actually scaling down by going from DVD player (480p) to receiver (upscaling to 720p). I will be better off letting the TV do the upscalling to 1080p...am I understanding this correctly?

Sorry I thought that model was 768p like nearly all of Sony's TVs.

However, the same principle applies. If the dvd player outputs 480p and the receiver upscales that to 720p, the TV will further scale it to 1080p. If the dvd player outputs 480p and you can tell the receiver to do nothing, the TV will scale the 480p to 1080p.

480p -> 720p scaling makes every 2 lines into 3 and likewise for 720p -> 1080p. But if you let the receiver scale the 480p to 720p then the TV will be further scaling those previously non-existent lines that were created as part of the 480p -> 720p scaling.

It may or may not look any different and that's why I say you have no choice but to experiment with each combination.
