Sony sxrd series (current)

[DILA4LYFE]

I have a question regarding the sony sxrd series curently out in the market. I have been told this set actually UPCONVERTS image to 1080p and does NOT accept 1080p signals from sources other than a computer or from PS3??

I dont get it....what does that mean? Can someone help me understand this.


Also, i know there are televisions that display in true 1080p right now...are these tvs also UPCONVERTING images like the current sony sxrd line?

im trying to find out if the picture displayed from a 1080p tv set in native 1080p resolution is the same as a tv that upconverts images to 1080p.


i hope i didnt confuse anyone by trying to find this out.

This has been discussed many times on this forum.

All HDTVs do some form of upconversion of SD signals to their native format. See the HDTV FAQ on "HDTV Formats".

1080P native format HDTVs convert all incoming signals (lower than 1080P) to 1080P. Some of these TVs accept 1080P (by various ways) and some do not. The fact that they do not makes little difference today, since there's little/no 1080p material available.

Also, it's been stated that 1080p material, downconverted to 1080i and then upconverted by a 1080P HDTV suffers little from this process.

Some "purists" however are waiting until the 1080P TV of their choice will accept 1080p signals, for example, via HDMI. There will always be something "better" if you wait.

I hope this helps.

Some report of HD 1080i inputted to 1080p displays and 1080p inputted to 1080p displays have had the reviewer not noticing any difference.
I believe this was in the CNET review of the Blu-ray player recently, using still and rapid-movement scenes.
I have had no problems with my SXRD with fast moving scenes with 1080i HD programming or 1080i upconverted DVDs to the set.
The Sony SXRDs with 1080p inputs are coming very soon, so if it is important to you, I would wait.

Interesting though that some 1080P TVs (Mits, Sharp) fail the "bobbing" test for 1080i signals though, while others do not.

Thanks, 57U, I had read that previously and showed it to my clients that were buying sets, right away.
Then I showed to my suppliers and we did a checkoff of what not - to buy for clients and sell/show them, unless they were set on a particular brand and model.
As for me, my Sony SXRD and Hitachi LCD RPTV (VX and VS were the same inside) sets passed and that explains why the other set (Rec/Gym) does not look as good to me and it is not my imagination.
That Sony 768p set, the LCD RPTV in the Rec/Gym area, did not pass, I'm sure of it, but it not used for serious HT anymore, just gaming and casual watching. :D
Those Mits sets - I had some picture concerns when these 1080p models first came out, but I thought it was just me, now I know better...they used cheaper parts for picture processing...ugh!

57U - Are you saying that the tvs that do accept 1080p signals, and upconvert the signal to 1080P - displaying the picture EXACTLY the same picture quality as a tv that DOES accept 1080p signals and displays them?

I went to best buy and they had the blu ray player hooked with the sxrd 60inch. They told me since the sxrd does not accept 1080p feeds, and since the blu ray player outputs at 1080p, the tv will automatically downconvert the blu ray signal to 1080i and then project that signal by upconverting it to 1080p. The picture still looked fabulous though.

He said had the sxrd accepted 1080p signals, the picture quality on the screen would have been better, to a noticeable difference.

I am on the market to buy a tv for my living room. I was thinking of one to hang on the wall. It has to be a 1080p tv...and my purpose for asking about tvs that accept and those do not - was to see if there is a difference in the picture quality between the upconverted image, versus that of a tv that does accept the 1080p signal and then projects it.


Here is my dilemma:

1. I can get the current 50 inch sxrd for a great deal, but i am unclear whether there is a difference in the picture quality between that and a tv that accepts 1080p signals

2. I would also love to have a flat panel on my wall in the living downstairs but there are not many 1080p flat panel sets bigger than 35 inches. The biggest iv found is a samsung 40 inch. Im looking at about 45-50 inches in size.

3. Should i wait for the new sxrd line about to come out, since they do accept 1080p signals. Speaking of this, i was also at circuit city and there was an associate there showing me the 1080p rear projection samsung 56 inch they had - it was fantastic...retailing for $2999.99. He told me the new sxrd line will most likely be even better.


Please let me know your thoughts

You believe a BB salesperson - Shame. The BR player needs to downconvert the signal to 1080i, if the TV cannot accept 1080P, then the TV upconverts to 1080P. Silly salesperson. A TV cannot downconvert a signal that it can't accept.

It has been stated on several sites, that, provided the TV doesn't "bob" the 1080i signal to 540P in it's internal processing (see link in post 4), that the final PQ will be indistinguishable from a 1080P feed.

Remember that final resolution is not everything. The quality of the TV and the quality of the processing comes into play more often than a number that says 1080P or 768P.

You may also wish to read the HDTV FAQ "What you need to do to your new HDTV", since the TVs in big box stores are rarely properly calibrated, although the newer ones are apparently a bit better than the older ones.

Viewing distance also comes into play. The human eye cannot resolve more than a certain number of lines from a certain distance. See Below:
