Home audio & video: Poll: Can you see the difference in picture quality...

Absolutely - but you must start with a true HD pix

I watch a friend's set. 1080 "Full" (not necessarily just p) is worth it. As many have said, resolution is only part of the story. It's overall pix quality counts, incl. contrast, color dynamic range and hue, and for lack of a better term "liveness." You must FIRST start with a true HD pix; many "HD" sources are not. Playing an appropriate video disc (like the BlueRay touted by many already) is one way, or a full HD live broadcast (like some news or football!) ok - it's a guy thing. For some broadcasts you feel like you could walk right onto the field (or into the scene) rather than watching a 2-D image! Much variation in room lighting and with LCD, Plasma, and DLP technology as well. I'm settling on DLP - and curious to see what pops out at the comm'l show in LV.

Difference between 1080i vs 1080p?
by wyatt.kwon - 12/12/07 11:52 PM In reply to: Poll: Can you see the difference in picture quality... by Lee Koo (ADMIN)
I own one of each 1080i/40in and 1080p/52in Sony LCD flat screens. With normal DVD and standard TV reception, my untrained eyes can not appreciate the difference. However, with HD TV reception or Blue Ray DVD player, the difference is really awesome! One regret that I have about purchasing a 1080p, I no longer watch 1080i in my master suite.
there is no 1080i LCD

720p vs. 1080 and 1080i vs. 1080p

i originally bought a 1080p dlp (boy was that a mistake) read my review to see what problems i had, it had a great contrast ratio and good black levels but the picture was horrible it was great for gaming tho.
as soon as i started looking for a TV to watch movies and broadcast on i started pointing out 720p's (larger then 40in) as i was walking down the aisle (i can actually see the blank spaces between the pixels, and i can fairly accurately guess the contrast ratio), really hd is relative to the size of the TV, a 50" 1080 isn't going to be nearly as Highly Defined as a 15" 720p, right now I'm on the highest def monitor i have its a 17" CRT that pulls 1200p (4:3) and it has a better picture then any TV i have seen so far.
30i vs 60(p)fps
if your comparing a movie such as the queen (i vs. p) your not going to see much difference, i see a sizable amount of difference between i and p when watching action movies (which is most of what i watch) i use i for my hddvr because most of the TV shows i watch are either originally broadcast in i (so there's no reason for the extra bandwidth to be wasted) and aren't high action (the simpsons, house, etc, etc.).
i bought a 1080p LCD from walmart the picture is ok but the black is way to bright, if cannon would get off there a**'s and get sed out I'm sure we would see a entirely new and better picture then the ones we are seeing now.
7 feet?

7 feet away from the picture might be fine on a 27 inch, but for those of us sitting 16 feet or further away, we can't really answer this question. I bought a 1080p 42" and I'm very happy. I bought the 1080p for "future" needs rather than current. HD-DVD/Blu-Ray can take full advantage of the resolution.
i don't have a hdtv
by MrMe003 - 12/13/07 4:02 AM In reply to: Poll: Can you see the difference in picture quality... by Lee Koo (ADMIN)
Well i dont have that hdtv in my normal television but if i download some HD material from the net and they are a 720p or 1080p..
well then i dont see any other changes than that 1080p is bigger but the sharpnes and quality of the video is the same.
lol
by froasier - 1/12/08 9:59 PM In reply to: i don't have a hdtv by MrMe003The "sharpness and quality" are the same because you're viewing them at native resolution on the same display. Since the 1080p video is "bigger" however you will be able to see smaller details. If you want to compare them on your computer, download 720p and 1080p versions of the same desktop wallpaper, resize the 720p one to the dimensions of the 1080p one, and view them both at 100% zoom. On the other hand, if you had a 1080p-capable monitor and viewed both videos full-screen you would see the difference. These aren't perfect comparisons because there's scaling going on, but it gets my point across--you're thinking about the comparison wrong--in this case you need to compare how much detail you can see in the image, because at 100% zoom on the same display the pixels are the same.
Yes, just slightly....

I had my Toshiba 720P 50" right up to my Sony 1080p 50" and they were both being fed the same source material.
During a movie or anything else having movement I honestly couldn't tell the difference in resolution. They both looked pretty damn good.
Where you can tell the difference is when you freeze frame the image (especially with computer graphics) and walk up to both TV's and eyeball them from about a foot away. Things are noticeably sharper on the 1080p set but that difference fades away quickly the further you back off.
In my opinion, unless you just have to have the 1080p sticker on the side of your TV to make you feel better I'd concentrate more on which TV has a better contrast and deeper black levels. My Toshiba may be 720p but I love watching it more than the Sony because the overall picture looks so much better especially during dark and spooky monster movies.
hdtv

Those equal YES and NO's tell you everything !
Very little difference between 720p and 1080p
by mickeyt1969 - 12/13/07 6:10 AM In reply to: Poll: Can you see the difference in picture quality... by Lee Koo (ADMIN)
I see a bigger difference between LCD/Plasma though the quality is not necessarily determined by ppi or format. Quality seems to be all over the place.
Sick of this Hype

What next, 1080T, Q, R? I've had hdtv on my 55" projector TV for over 3 years and after the initial pleasure of viewing HD, ones eyes, at least mine, gets accustomed to watching it and now I really do not see any great difference in digital channels and HD...i compared that with Color TV when it first came out well enough to be enjoyed. I watched crap sitcoms just because of the color...now its crap in HD. That wore off and so will this...maybe, just maybe 3D perfected in HD would make a difference..but I am not holding my breath.
3D is coming fairly soon
by froasier - 1/12/08 10:07 PM In reply to: Sick of this Hype by BoothbayThe technology is here (displays), but all the parts have to come together (content and players) before it will become mainstream.
It depends on the type of tv
by rfrancia - 12/13/07 6:23 AM In reply to: Poll: Can you see the difference in picture quality... by Lee Koo (ADMIN)
In my experience, it depends on what type of equipment you own. I have a older 32' Sharp LCD TV that is a 720p/1080i set. I did see a small difference when I bought a Sharp Aquos 1080p set, barely, when using my FIOS TV HD Receiver. But a recent purchase of a Pioneer PDP-4280, a 720 Plasma TV, changed the idea that 1080p makes a big difference as I believe my pioneer plasma tv has a better picture quality than my 1080p Aquos. I preferred lcd than plasma but after seeing the picture that came out of my plasma tv, I was sold! I don't have any bluray or hd dvd player to fully know if there is a difference. If I had to guess, I still think my plasma tv would still have a better picture quality than my lcd tv.
Seeing the difference, or maybe not
by olderposter - 12/13/07 6:37 AM In reply to: Poll: Can you see the difference in picture quality... by Lee Koo (ADMIN)
According to my experience it takes a horizontal resolution (line density) of 3 or more lines per degree to be able NOT to see the individual lines. Get out your trig boooks, it's a simple calculation. That tells you how far from the screen you viewer needs to be to not notice the scan lines with a fixed screen height. Or if viewing from a fixed distance, how small the screen must be not to see the scan lines.
The only time I ever bought a high tech device before the price, development, and bugs were mostly settled out was for a Mac 128. So I will wait a bit longer before taking the plunge. But I have spent hours at the local mass merchant electronics shops viewing their demos and talking the the reps. I love 'em all so far when I'm not paying.
3 lines per degree???
by SoftDad - 12/13/07 4:35 PM In reply to: Seeing the difference, or maybe not by olderposterWhoa baby. That sounded weird - the moon is about 1/2 degree across and it sure takes a lot more than 1.5 "lines" of resolution to show the detail I can see in the moon. Perhaps you mean 3 lines per minute of arc - but that's too fine. OK, let's do the math. When I look at my 42" 720p plasma from 5 ft. I can start to see pixels. Each pixel is .027" across. Now, arcsin(.027/60) = .0258 deg, which says I'm seeing almost 40 lines to the degree.
So there!
