Plasma vs LCD

Inertia said:
Picture qualtiy is excellent. Especially local content like DSTV, which i was very surprised abt, produces very good quality images. It's got almost exact HD compatibility, so no upgrading come 2010 :D...

er no.. it is XGA-ish (1366 x 768). HD is 1920 x 1080. It is a so-called HD-ready set, not true full-HD, and needs to downscale HD images to display them.
 
The clarity, sharpness and brightness on many LCD screens surpasses that of plasma. The screen sizes are perhaps somewhat smaller, but you will see the difference in image quality immediately.

LCD screens have more life to them than most plasma's.. put a decent LCD next to a decent plasma and you will notice the difference. Size isn't everything - if you have crisp, clear image but a slightly smaller screen then just move your couch a little closer :) stay away from projection TV's though, they're way too bulky and look like something from the 80's.

*sigh*.. not neccesarily as has already been said earlier in the thread...

Sony Grand Wega is an "HD Ready" LCD Projector. A 42" Grand Wega will outperform both a plasma and an LCD panel at the same price point. Although you can't mount it on a wall, the footprint is smaller than a Plasma on a table stand. And if you think this is ugly, you must have strange taste :)

Nope you are wrong my friend.

HD comes in different flavours.

1080i/p, 720i/p

1080i/p has a resolution of 1920x1080 and is either interlaced at 60fps or progressive at 24fps.

The same goes for 720 but the res is 1280x720. If you take 720P and compare it to 1080i the actual image quality is very close.

720P is full HD. Most HD broadcasts overseas are not 1080P but either 1080i or 720P.

It is a good idea to get a set now with HDMI and with a native res that supports 720P or higher.

The Toshiba DLP Rear Projection TV's are amazing.(They run 1080P Native Res) I saw one when I was in the states and at first was thinkin damn thats a nice plasma only when I looked at it from the side did I see it was Rear projection. Was also displayed next to a plasma.

The Sony Bravia range are awesome. We have been looking at the 40 KLV-V40A10 retailing for about R39 000. I am sure you can find it for less tho.

It is an amzing set.

well almost..HD comes does come in 1920x1080i/p but only 720p AFAIK
1080i/p has a resolution of 1920x1080 and is either interlaced at 60fps or progressive at 24fps.

almost again. " i " can be interlaced at 50 or 60 FIELDS per second (not fps which means frames per second). "p" is progressive at 30fps or 25fps.<edit: I'm wrong here - 720p is at 50 or 60 Frames per second - sorry> 24fps is the speed that film (movies) are recorded. to all intents and purposes, it is difficult to differenciate 1fps...so as a matter of course most PAL (25fps) DVD movies run very slightly faster than the original film movie.
The same goes for 720 but the res is 1280x720. If you take 720P and compare it to 1080i the actual image quality is very close.

Using what source? A full HD 1080i source is going to look MUCH better on a 1080i panel than a scaled down version on a 720p panel. The advantage of 1080i over 1080p is the reduction of bandwidth of the signal, and the advantage of 1080p over 1080i is the reduction of motion artifacts and edge jaggies in fast moving footage.

720P is full HD. Most HD broadcasts overseas are not 1080P but either 1080i or 720P.

nope 720 is HD but not "Full" HD.

I saw these units in Japan last year. They are very good, especially the black levels which are far superior to LCD. However, they have a very irritating colour smear on fast moving objects - because of the way the light is projected.
The Sony Bravia range are awesome. We have been looking at the 40 KLV-V40A10 retailing for about R39 000. I am sure you can find it for less tho.

I agree, ATM this is the best LCD panel TV... a bit pricy tho' (best price I have seen is R36K - waaaay out of my price range). But I still think that a 50" Grand Wega is a better buy atm.

HD comes in 720P and 720i but for broadcasting they only use 1080i and 720P.

From actually seeing HD in both formats I can tell you that they are extremely close. Saw them on both DLP rear projection and also on 1080i CRT sets.


The reason 720P and 1080i are so close quality wise is the amount of pixels displayed at any given moment.

720p = 1280x720 = 921600
1080i = 1920x540 = 1036800 (Reason being it displays 50/60 half frames per second. This means at any moment you are only seeing 1080/2=540 lines)

720P is the one I would prefer. Unless they start broadcasting in 1080P.

Back on topic. If your budget allows not a lot of tv's look as good or produce such a nice image as the 40" Bravia.

The only disadvantage of an LCD is that a plasma produces a better black.

you missed my point: What was the source? I have done tests with a HD signal generator on a number of sets, and believe me, if the source is 1080i, there is a HUGE difference between a 1080i set and a 720p one. Even on the same set with capability of both, the 1080i looks smoother and clearer.

You would have to have incredible eyes (and brain/nervous system) to avoid the persistance of vision, considering that each field is displayed for 1/50th of a second. In fact, as far as your eyes and brain are concerned, you are seeing the full resolution of the signal: more than twice the pixel resolution of 720p. The only disadvantage of "i" is motion artifacts, where fast moving objects get a slightly jaggy edge... a freeze frame shows it as a "venetian-blind" effect). Also, I think for now, it looks like 1080i will be the standard for broadcast because the bandwidth required is only slightly more than 720p. But with the advent of HD-DVD and Blu-ray, we will see some 1080p content.

The sources were 2 shows cant remember the names but one was one FOX and in 720p the other was on CBS and 1080i. It was at a Best Buy in Florida and they showed me both the shows on both tv's and 720p was more pleasing to watch the 1080i flickred like when you have your monitor set at 72hz or lower. I cant use my monitor at anything lower than 72Hz cos my eyes start to hurt.

then you won't want 1080p... refresh rate is 25/30Hz.:D

edit: can you watch movies at a cinema?

Yeah can watch it at a cinema but it also hurts my eyes. It's the worst when there is a lot of white in the image. Suprisingly Cinema(24fps) is not that bad.
 
I also asked the plasma vs LCD question in another thread, and low-and-behold, I walked into a shop today to buy an iPod camera connector (approx R300) which they didn't even stock, and walked out with a LG 32" LCD TV for our bedroom. Luckily I didn't have to justify it to my wife, as she was the one who wanted it :D
 
Thanks for all the info, went into Audio Vision Tygervalley and the guy recommended this Hitachi model which is HD ready. He said if I remember correctly there are no Sony HD ready plasmas in SA.
 
Hey Person, are you around? How much you can get the "Sony 42" FWD-42PV1 Plasma Display Panel" for? I guess everyone would like to know.
 
swordfish1 if u r refering to me I have not sourced a price, but only had a look on Sony.co.za
 
"Person" is the nick of a dealer who frequents these forums usually offering very competitive pricing.

yep, I am surprised he hasn't replied yet :D

I see that the MSRP has dropped to 17,000, it was 19,990 or something like that, so I wonder if one can get this panel for about 13-14,000 or so.
