Going from 900p@16.4" to 1080p@18.4"

[hendra]

When watching Blu-ray, would I notice more detail if I switch from 1600x900@16.4" to 1920x1080@18.4" laptop or would it just be a bigger screen?

Yes, you would notict a difference - on both fronts.
Bigger screen and higher resolution.

Contrary to what come would have you believe, you do *NOT* need a huge ass screen across the room to get the benefit of Blu-ray.

Post typed from my #1 BD VAIO - 17" and 1920x1200 display.

I have to disagree. You won't see any difference whatsoever other than the obvious larger screen. I went from a 1080p 42" tv to a 50" 768p tv for my living room, and guess what...no difference in sharpness or detail at all and that's even if I'm right up on it. At that size the lines of resolution don't have enough space between them for you to see between with the naked eye even if you are right up on the screen. One panel may have a better contrast ratio than the other so black levels may vary, and the video cards in each could give a different picture, but as far as the resolution goes it will not affect the movie at all.

42" to 50' at he same resolution of 768?
No doubt!
From 8-10 feet, that small of an increase of screen size with no increase of actual resoliution, there will be little change whatsoever.
Had you jumped t0 1920x1080, you would have seen an improvement - one would hope.

You must not have read my post correctly. My 42" is a 1080p tv with a 1920x1080p resolution and my 50" is a 1366x768p resolution. Being right up on the screen you still don't see any difference in sharpness, and I've gone back and forth between the two many times to try and see a difference. You're just not going to unless there is a drastic size difference in the screen, and when you are talking about a 17" or 19" screen the difference is absolutely impossible to tell with such a small change in resolution. The lines are just way too close for the eye to determine the difference.

My bad!
Still...

So, 768 is the same as 1080?
What's the source?
Uhm, I can see the difference between my 17" 1440x900 as opposed to the other 17" 1920x1200.
Same size, higher res - there is a big difference!

Sounds like you have a setting or two wrong or using some inferior source material.

Maybe dadkins can explain this, I have asked this question before on a different thread, same basic subject and not gotten an answer. If the Blu-ray disc has a 1080P version on it and you are playing it to a monitor/hdtv at a lower resolution where is the downsampling occuring and wouldn't this potentially affect image quality or accuracy in reproduction?

That all depends on the player/playback source.
With a computer, the scaling can either be done on the machine/Graphics settings or the HDTV itself will handle the scaling.

With a PS3, the PS3 can handle the output scaling or the TV can handle it.

With a STB... I really haven't had any experience, but I imagine you could just let the TV handle it if the STB doesn't provide scaling abilities/output.

To truly appreciate the 1080p of Blu-ray, one needs to display the video at the proper resolution and view the display at the recommended distance.

Yes, the downsampling will affect the PQ.
Not by a large factor, but it will be less than ideal.



Hope this helps!

Thanks for the answers dadkins. So in the end the OP might be affected by how his system is scaling the image, sounds like two different monitors and one laptop PC. As complicated as resizing an image would seem to be I would have thought it might be significant on replaying a video but I will take your word for it.

As a personal preference I would always want to watch a Blu-ray in the full 1080P format, but all I have are LCD HDTVs no Plasma, so I can see the screen-door effect if I am up close. Overall I would be more concerned with how the scaling treated the tossed pixels in a real time situation like a video. My most intense viewing is of jpeg slideshows so I have a chance to look for minute details in the image.

Lojack you have no idea what you are talking about the first thing that indicates this is the fact that you do not even know what the resolution of 1080i is, it's exactly what 1080p is which is 1920x1080 pixels of interlaced lines instead of progressive hence the "i",not the resolution you put. I understand the point you are trying to make with taking a quality piece of hardware over crap but to make a statement that reviewers think some 720p pioneers are better than the most recent top of the line 1080p displays is ridiculous and about 2 years too late since Pioneer has been making only 1080p big screen plasmas for the last few years. The one thing I have noticed about this forum is it does not have as many knowledged people as others and alot of posters you can tell are teens which is fine the problem is people put wrong know it all information out there and others believe what they are reading...nest time do a little research before you go and argue with people who know a little more than yourself...

Yes, I do know what I'm talking about and I do extensive research on a variety of things. I do know that 1366x768 is not 1080i and the statement was an error which I've corrected in the original post and clarified in others. The point of my statement is still the same. All sorts of things contribute to picture quality and resolution is just a part of it. Static resolution is not nearly the most important part of the equation. While we're at it lets talk motion resolution and the fact that 1080p LCD TV's motion resolution range from 310-620 lines(most of the high-end models were at 580 while the low-end ones dropped to 330). 1080p plasmas range from 800-920 and 720p/768p plasmas range from 580-620. Since we're talking about laptop LCD's I stand by what I've said...Blu-rays will not see a drastic improvement..if at all..going from 1600x900 to 1920x1080. There is only one display in existence that displays all 1080 lines during motion and that's the Samsung 46A950 LED LCD. In fact, there are a lot of 1080p LCD's that have static resolutions lower than 1080. Some are as low as 900 lines with others displaying 1,050 lines. Read THIS and check out the resolution tests results they provide.

Define "up close".
My 42" LCD only starts "showing" the individual pixels when you get within 2.5 feet - too close.
Anything 3 feet and above, no "Screen Door" effect.
Maximum distance recommended for my 42" 1080p LCD is 5.5 - 6 feet.
I sit normally just under 6 feet.
The PQ is phenominal!

When I am looking at a jpeg slideshow I have created sometimes I will get within inches to see the detail in the photo. I use a 14MP camera so the image is downsized by the time I have run it through my Sony Vegas/Architect software and unfortunate recompression during rendering. Then when I am viewing it on the screen I will get close to see if I kept the detail I wanted or maybe just notice something in the photo I had not seen before. I am becoming slightly far sighted so the big screen is more comfortable to see than a 22" computer monitor.

I know this forum is aimed at Blu-ray movie watchers in general, but the HDTV has a lot more to offer for my use. Photography is my first love, a big screen finally makes it easy to see great detail in a living room environment. I can't wait until stuff like 4K resolution TVs come out!!
