Hello,
I have a 37 inch Sony LCD which is 1080i but can receive 1080p, so which resulotion should I choose on my PS3?
I know 1080p is a higher resultion, but I was wondering if it has draw back to use on a 1080i LCD.
Hope you could help me with your experiance.
Thanks.

Set your ps3 to display 720p as it will look better than 1080i
The tv can recieve 1080p signals, but will not display them as it's native res is 1368 x 768 which is 720p

1080p and 1080i are the same the only differance is how the picture is scanned. on a 37 inch tv you could not see any differance between 1080p or 1080i all tv networks broadcast in 1080i or 720p only blu ray discs are 1080p I have a 720p and a 1080p tv and the picture is the same

david 66, Your statements need some correction.
First, 1080i and 1080p are not even close to being the same. 1080i is displayed as a 540 line (400,000+ pixels) interlaced image. 1080p on the other hand is displayed as 1080 line (2,000,000+ pexels) progressive image. NO CONTEST 1080p has 5 times the number of pixels! This difference is very noticable on any 1080p high quality 24" display or larger. Sorry that your vision is so poor that you can't see the difference.
Secondly, (A) All networks do not broadcast in 1080i or 720p. Most programing is 480p until prime time when most are then 1080i. 720p is only used for sports. Why because it is "progressive" and far better for fast motion than an interlaced image. 1080p would be the ultimate for everything and we will see that in the near future. Just look at the number of 1080p channels available and coming from Direct TV and DISH Network. In addition, many DVD players now upconvert to 1080p and all outboard Scanners/Scalers and High End Processors, as well as many A/V Receivers can cross convert any input resolution to output at 1080p for delivery to your display.
(B) BluRay is far from the only 1080p source available, what about HD-DVD (even though its no longer supported, lots of players and discs out there), and of course Sony PS3 and XBox 360, HTPC's (Home Theater PC's), which are capable of resolutions far better than 1080P, I could go on and on....
Finally, If your 720p (900,000+ pixels) set looks as good as your 1080p (2,000,000+ pixels) set with 1080p source material, after down converting the 1080p to its native resolution of 1366 x 768 (most advertised 720p sets are really 768p (1,000,00+ pixels) sets that just upconvert 720p or deinterlace 1080i to 540p and then upconvert it to 768p) you either have a really poor 1080p set, or as I suspect, (and I'm not trying to be mean) you have very poor vision. Have you thought about an eye exam? Really...
zonkie, You are correct 720p is 1280 x 720, just as 768p is 1366 x 768 and 1080p is 1920 x 1080. There are 18 different Digital TV standards that range from 480i to 1080p. By far, the best situation is to purchase a 1080p. Doing anything else, just does not make sense. Good LCD 1080p sets can be found for less than $1000.00. By the way, if you can afford it, I would highly recommend that you purchase a 1080p LCD with 120Hz refresh rate. It takes care of any motion blur issues that some 60Hz panels have on fast action scenes or sports. Also make sure that the HDMI inputs are 1.3 not the older 1.1 version.
Please feel free if you have any other questions. Bob

zonkie,
To answer the question about output on your PS3. The PS3 can output 1080p, 1080i, 720p or 480p. Your sets native resolution is 768p (1366 x 768). The answer, try both 720p (the set will upconvert to 768p) or 1080p (the set will downconvert to 768p) either way you can not escape the extra processing the set will need to do.(Just another reason why a 1080p signal sent to a 1080p display (1920x1080) will kill a (768p) display everytime, no processing!) It is true however that a 720p source sent to a true 720p panel (1280x720) will look damn good, but still far short of 1080p, it only has half the number of pixels, 900,000+ vs 2,000,000+. Just decide which way the sets scaler chip does the best job and go with that output from your PS3. To take full advantage of the PS3, you need a 1080p panel, period.

All HD program on the networks is 1080i or 720P 1080p requires lots of bandwith and the networks are not willing to go up to 1080p because of cost no matter what you say 1080 i and 1080p are the same the difference is how the the picture is scanned and you will not see any difference on a 37" lcd if you are willing to go to a 50" or higher lcd and you set close to the set you will see see more 1080P does not have more Pixels than 1080i 1080I is displayed in the set first it displays even lines then goes back and does odd lines 1 3 etc this is done so fast you can not see it happen Because a set is 1080p does not mean the quality is top notch I have a bluray and aHD DVD player and some of the discs are 1080p and the quality of the picture is not any better than a upconverted dvd also i have 20 20 vision

I have some movies on blu-ray and regular dvd, I have run them both at the same time and changed input sources on my tv, The upconverted version does not look as good as the blu-ray one.
I will agree a unpconverting player looks good, But it is not going to look as good as a HD-DvD or blu-ray.

You are badly mistaken. 1080i (i stands for "interlaced") does in fact display one field and than another, refreshing 60 times per second, however, it is only displaying 540 lines per field, hence the term "interlaced". In contrast, 1080p displays all 1080 lines per field, hence the term "progressive", refreshed at the same 60 times per second. THAT IS THE DIFFERENCE BETWEEN 1080i AND 1080p, ONE IS INTERLACED 540/540 THE OTHER IS PROGRESSIVE 1080/1080! 1080i displays approximately 900,000 pixels, 1080p over 2,000,000 There is no gray area, 1080p puts many more pixels on the screen, and looks much smoother because it is not flashing back and forth between frames. In the time it takes 1080i to paint it's 540 lines, 1080p has painted 1080, 720p has painted 720, by the time 1080i has painted 1080 lines, 1080p has painted 2160, and 720p has painted 1440. End of story. Period
The same thing applies to the progressive scan output of standard DVD players. Why do you think that 480p, progressive scan output, was such a big deal and selling point when it was introduced? Because it puts many more pixels on the screen in 480p, progressive mode, 480/480, compared to 480i, interlaced mode, 240/240 and is much smoother.
Also, because 720p is progressive scan 720/720 and the fact it is superior on fast action scenes, most people find 720p to be superior to 1080i. Thats why ALL sports, regardless of network, are broadcast in 720p, not 1080i.
In addition, I find it hard to believe that you watch HDTV or you would know that most of the time, the channels are in 480p so they can split the bandwidth and broadcast 2.1,2.2,2.3, etc in the same space. 1080i use 19.34 MBps, very close to the total the networks are allowed of 19.4 MBps, while 480p only uses at best, 8 MBps, typically much less. Only during primetime, will you see 1080i, sports always at 720p. Have you not noticed at 7:00 or 8:00 pm, depending on the network, when you are changing channels that your display will indicate 480p at 7:59pm and then 1080i at 8:00pm for the same channel? This will last through primetime and then it will drop back to 480p.
I also wonder about your BluRay and HD-DVD Players... The transfer has alot to do with the end result. Not all discs are created equal. I have some that are fantastic and others that are very poor. Also, if you think that upconverted DVD's are even close to Bluray or HD-DVD's and your vision is 20/20, sell your display and players and buy new ones. They don't even compare.
If you need any additional information, let me know, I am a 38 year industry professional, CEDIA and ISF certified.

Put 10 people in a room and show them 720p and 1080p signal and do not tell them what is 1080p nine out of 10 could not tell the difference double blind test it works every time I think this 1080P was put on the public by the tv manuf. How many people have bluray or hd players not many Lots of people do not even know what bluray is and the way things are going with the stock market there will be even less interest in bluray

David, Your statement was "1080i is the same as 1080p, on a 37" TV you could not see any difference between 1080i or 1080p"
With 1080p having more than twice the resolution of 1080i, 120 Hz refresh rates not to mention the motion blur, artifacts, jaggies, etc. that are common with 1080i, most anyone could tell the difference on a high quality display that is properly calibrated and set-up.
If you were to conduct the test using sports or fast action scenes as the viewing material, it would be silly. My clients see the difference most every demo.
However, it could be argued that on inexpensive displays, the difference may not be quite as obvious for many different reasons, having little or nothing to do with the source material, but the limitations of the displays themselves.
It is great to see so many people interested in HD displays and the pros and cons of different set-ups. If we coud get the rest of the US as excited and interested as people on AfterDawn, we could be watching broadcast TV at resolutions approaching Digital Theaters (4096 x 2160) or higher.
I have been around high resolution projectors for a long time, starting with a the Ampro 4300 (2500 x 2000) and the Sony G90 (2500 x 2000) back in 1995, way before any video source existed with output capibilities to match. I still watch the G90 on a regular basis, as does Widescreen Review. It is still top notch. No digital projector can match the black levels of this monster. Close but not equal.
Keep the interest high. We need more of it! Bob

My 42" 1080P display has the 120HZ refresh rate and i have turned it off as it causes more problems than it solves on some sd dvds it causes stop and start motion on HD dvds that is not a problem so i leave it off I have read a lot of displays are having this problem with the 120 Hz I have verizon FIOS and it is not a problem with the cable channels the only problem is there is a lot of compression on cable channels like HBO etc the only channels with out the compression problem is Cinemax all the channels are in HD and no compression problems at the present time. I get 100 channels in HD at the present time and the said more are comming I better shut up and go to bed

David

Thanks a lot guys for the tips. I learned a lot.
I can't really afford the 1080p with 120 refresh rate now ... I know it is much better, but not always the eyes can have what they like :)
I noticed when I checked only the "720p" in my PS3 that the Cross Bar is more clear and the letters are bigger. Maybe later I will try with some BlueRay and test both signals to be sure which one would be better for my 37" LCD.
Thanks a lot guys ;)

I should also explain that when you are taking about mircodisplays (LCos, DLP, RP LCD, etc) or fixed pixel displays (Plasma, LCD Flat panel)they are by nature, inhertantly progressive scan, so when they see a 1080i source, they deinterlace the image to 540p and convert it to that sets native resolution (720p, 768p, 1080p, etc) for display.
The problems you mention are very common with all users and a paper could be written explaining it all that would fill volumes that very few people would understand. I am still learning everyday. It is a very complex subject.
There are so many variables as far as the source material (film or video based) and if you start taking about 720p/60 vs 1080p/24, etc. it can be very frustrating for the average customer to choose all the proper settings (both on the display and DVD) to gain the best possible picture from the display.
Not to mention the fact that many people see the HD SAT feed at Best Buy, Circuit City or Walmart, contrast/brightness cranked to the moon, take the set home, connnect it to standard cable, DVD, even VHS and it looks like crap. That does not help the problem.
Try them all, pick the combo that looks best on your display, to your eye, on whatever source material you are viewing and enjoy!
