1080p vs 720p

[Genius.]

Whats the advantages of having a LCD/Plasma that can broadcast in 1080p if the highest we can recieve is 720p?

 

[Keeper]

playing blu-ray discs at full definition.

Better Resolution if you use it for a PC Monitor.

 

[gifs]

PS3 and Xbox games are also in 1080p

 

[Dolby]

Yup - PS3, Xbox and Blu Ray ...

Bear in mind the difference between 720/1080 at under 46" is quite small

Really? Why would the difference be small if the resolution is higher?

I would think that 1080 would show a big difference to 720

Boggles the mind! When on a PC screen the difference at higher resolutions are so apparent.

 

[Keeper]

it's simple really.

the problem doesn't lie with displaying pictures with colours fading inbetween smoothly like on a face. the problem lies with text, as it has a hard edge.

There is a difference. Keep in mind I didn't say no difference and I diud mention size - viewing distance and size of panel make a difference. As does that fact of what you sually watch (native 720 or 1080 - and which needs to be up or down scaled)

Tons of links to back it up - but check here http://www.thebestplasmatv.com/guides/720p-vs-1080p/

So, if I watch in 1080p, and sit the correct distance, etc for 1080p on a 32"" it would be much better than if I watch 720p and sit the correct distance, etc for 720p on a 32"". Same for 40"", 46"" >>>>> Simple really.

That's the graph. If you sit too far away SD looks like HD. If you sit a bit nearer 720p looks like 1080p and you need to sit quite near or use binoculars to tell the difference for small screen sizes (46 inches and below). Rule of thumb: sit within 3-3.5 screen heights to enjoy HD.

Resolution is one thing.

Then there is contrast and colour depth.
Dynamic Contrast is something which the marketers always punt and it always catches out the n00bs. Static contrast is what one should look at.
Colour depth: 6bit display vs 8bit and some makers claim 10bit although I doubt that as even a 24 inch computer display at 10bits starts at R25,000.

Finally choice of plasma vs LCD. OLED is coming up. High End plasmas are expensive but deliver the best picture - most people say. I tend to agree.
LCD movies on Philips, Sony and Samsung LCD screens just don't look alive to me - it could be the lower colour depth or contrast of LCD vs Plasma.
Anyhow other people prefer LCD, of course the best TV on the market is a Pioneer Plasma. Sadly the Plasmas we get in SA these days except for
Panasonic Viera sets - and I don't think we even get full HD Panny's, are poor quality. We don't get Hitachi or Pioneer Plasmas. At the same time Toshiba
and Sharp make really excellent LCD TVs too. With OLED TV and "Laser TV" coming around the corner we may see even better quality but at huge
price premiums.

Shows a nice comparison of cr@ppy contrast on OLED, LCD vs excellent contrast on Plasma sets.

Although the debate between LCD and plasma has raged on for years, the real battle only started two years ago when manufacturers started producing LCDs big enough to go head to head with plasmas. Now that it has been raging for two years, we've seen some interesting trends develop. LCDs have been very successful at pushing plasma out of its most popular size, 42-inches, and some manufacturers have stopped producing that size all together. Also a result of the success of LCDs, the number of plasma manufactures has decreased over the past two years. Pioneer is the most notable to announce its plan to stop producing its own plasmas starting with the next model and will instead buy glass from Panasonic, but Hitachi and Phillips have also announced similar plans -- and Fujitsu got out of the display business all together. Some might use these events combined with the latest green movement to conclude that plasma is dead, but not so fast.

Plasmas still offer the best value in the 50+ sizes and the best contrast and color reproduction -- which any videophile will tell you is way more important than brightness, which seems to be sole reason why the masses prefer LCD. And plasmas aren't completely in the grave yet -- in fact, most of the biggest manufactures still sell plasmas including Panasonic, Samsung, LG, Hitachi, Pioneer, and Vizio. In fact, recently things have actually started to turn around for the PDP sector. The most notable trend is that the latest plasmas from Hitachi, Pioneer, LG, and Panasonic all pass the latest stringent Energy Star requirements of the 208-Watt "on mode" and less than 1-Watt "standby mode." And the market is showing this comeback as well which is indicated by the latest DisplaySearch report which showed that plasma sales grew by 37 percent year-over-year in the third quarter of 2008 -- in a time that is very hard time for any market to show growth.

So while no technology can be successful forever, plasma has at the very least a few years left, and we believe it won't be LCD that will kill it. The only technology that actually seems poised to replace it is OLED, and with the biggest (and only) consumer model at 11-inches, there is plenty of time left on the clock for plasmas. That being said, we only see two main markets for plasmas moving forward as LCDs continue to grow in size and shrink in price. The first being videophiles who demand the best contrast and color money can buy, and the second being value shoppers looking for a way to buy a 60-inch TV for as close to $2000 as possible. But with the latest LCD LED-backlit displays making huge strides in color and contrast, and Laser TVs hitting the streets, anyone who tells you they know what is going to happen in the next 18 to 24 months has no idea what they're talking about.

The keyword is correct distance.

If I put my PC screen on low resolution and then again on high resolution for the same distance there is a big difference.

Really IMHO its all in the mind and your own viewing perception. Resolution and size of LCD TV's matters for me. I can find no reason to con myself to justify spending/wasting money on a sub standard product here.

Some people can take advantage of the extra lines of resolution but sometimes, it's an unnecessary cost. Simply locate your viewing distance on the right hand side and screen size on the bottom, connect the two lines and bam, your optimal screen resolution. For instance in the Engadget HD lab, we sit around 10 feet away on our AOL-issued rolling chairs and we wouldn't see a picture quality difference if our 42-inch HDTV increased from 720p to 1080p. Everyone's HDTV viewing situation is different and while 1080p might be slammed into your face while shopping for a new HDTV, it might not be necessary for you

http://www.engadgethd.com/2006/12/09/1080p-charted-viewing-distance-to-screen-size/

But most probably it will matter once you get into the HDTV fold and get used to the better quality.


Also I noticed a major difference in those pic's posted earlier. See the text specifically. Shows the detail difference. The rest of the pic's is bad examples.http://www.thebestplasmatv.com/guides/720p-vs-1080p/


Better pic's were shown during the HD PVR/HDTV debate during the olympics.



Yeah, then colour, contrast and definition also add to the complexity. Dont even mention the dreaded motion blur "lag" and judder during fast movements! Specially on the cheap HD ready units. LOL.

Thus IMHO just buy the best you can afford or rather save more but stay away from the now cheap HD ready crap unless you have to buy it now due to affordability and cannot wait to save. I would rather save longer for the better units as the difference in price does not warrant buying the cheap HD ready resolutions. The cost difference to something better is not always that much. Check the specs of the better models that interest you, save and wait for a "bargain".

if you are serious about properly setting up your viewing room, you will definitely benefit from 1080p (and even 1440p.) Why? Because the 1080p resolution is the first to deliver enough detail to your eyeball when you are seated at the proper distance from the screen. But don't just take my word for it: read on for the proof

The question then begs, are you buying the HDTV (LCD or other) purely because it fits your lounge or are you buying it for the benefit of the quality it brings for HDTV/DVD entertainment or enjoyment?

And this regards to the motion blurr.

I'm not sure what you're on about. This graph only looks at resolution and distance. The bigger the SET the further away you can sit to tell HD from SD.
That's all that graph shows. If you want to buy a full HD 40 inch set and want to use it in a large room - well you're fooling yourself. It will work maybe for the guy who sits closest to the screen but everyone else will see the same as on an SD TV - hence the need for binoculars.

Now there are other things. Colour reproduction and depth - among other things is the display 8 bit or 6 bit plus dithered or 10 bits or 8 bits and dithered. Mind you, I'm not even sure BD can output 10 bit colourspace but
difference between 6bit and DiFRC and genuine 8 bit is noticeable once you know what to look for - you'll always see it. Contrast, viewing anlgle, refresh rates etc - all important. Point is that this article speaks only about one thing and that is screen resolution vs screen size. Have a big lounge - you need a 60 inch TV. That will set you back R70-80K easily for anything decent. Have a tiny flat - 32 inches may be enough for you.

 

[I am Penguin]

BTW I gave the link to the originator of the graph you linked to with his view of the topic at hand in this thread.

Now nobody denies that a 60"' is expensive and nobody indicated they are looking to buy one. Off topic again. The OP asked to explain the advantages of 1080p as compared to 720p. Thats the topic. Not the types of available screens and the best makes or brands and neither the economy.

You really sound like a furniture Store floor salesman. Which shop is your domain? Hmm?


This is the problem. We are discussing 1080p V 720p as per topic, therefore the graph and information given.

You are discussing "OLED, LCD vs excellent contrast on Plasma sets" off topic.

720p source:
Depends on the size of the screen, and how close you're sitting.
If the screen is really big, or you're sitting close to it, you might see the 720 lines, but with a 1080 TV it's more difficult to see them.

1080i/p source:
Of course, a 1080i/p video looks clearer on a 1080 screen.

Sheesh. I did not know these screens can broadcast as well...

 

[Genius.]

Thx for all the info.

Ended up buying the 40" Sony Bravia 1080p.

The LCD is for my bedroom so it is more than big enough.

 

[wizdumb]

so for a small room, a 720 would be sufficient, if i understood everyone's comments?

also for lcd, is the higher the contrast ratio the better ie 1:15,000 better than 1:1000
