Is 720P good enough for a 42 inch screen ?

[Nelson de Leon]

If you're 12 feet away, it's good enough. Pero as you get nearer, mashalata mo yun pixels so you would like a higher resolution tv.

Teka, we're talking plasmas and lcds dito...?

[carlo.A]

From my experience with my tv (55 inch) from 6ft away. It's extremely hard to tell the difference between 720p and 1080p.

I'm watching 720p material on my PJ about 92 inches size.. Ok naman sya so far... Or baka wala akong GoldenEye he he he

Is 720P good enough for a 42 inch screen ?

kung 720 ang source ok yan.
mahirap mag compare kung iisa ang source at iisa ang tv

[javauser]

My 720p mkv files look like crap on my 1080p projector. Of course im using a 100in screen.

match kasi dapat ang source at screen

[raider125jeigh]

elms and i played 720p on louie's pana via htpc and seems to be good though... sorry ot ako

720p still ok with 42inch ...
if your playing it via htpc or media player check the information of the file kung 720p talaga
meron kasing file na file name 720p pero when you check hindi pala talaga..file name lang sya hehehe

on my 40 sometimes its hard to tell the diff of 1080 sa 720 unless the file is really crap
viewing it at 5-6ft

[javauser]

Maybe with the player i am using. Ill experiment with vlc

[[dcw]aaron]

sa mga nabasa ko 55" below di raw mapapansin ang difference ng 720 and 1080 in a certain distance. ako naman on my 51 plasma 720 lang rin pinapanood ko kasi 720 rin ang native display ng panel. ok naman and ok rin ang 1080 di ko ma differentiate. viewing distance is prolly around 5 - 6ft from the tv.

Mga sir okay lang ba na vga cable ang gamit ko sa HD movies? Im using 42" lcd with my htpc. Medyo grainy yung display. Or i need to buy hdmi o dvi cable? Thanks

I would suggest the HDMI route.

Para hindi ako OT:

for a 42" screen 720p is good enough, will you notice the difference if you play 1080p? my answer is also yes but that will depend on how near you are to the screen.

[lightyears27]

Thanks sir sa reply. Bago pa lang kase akong nahuhumaling sa HD movies. And isa pa pong tanong. Ano ba mas magandang unahin. AVR or speaker? Hindi kase kaya ng budget ng sabay hehe. Sensya na po sa mga tanong

[lightyears27]

Anyway. Puro 720p po pala karamihan ng collection ko. Ang laki kase masyado ng 1080p mauubos agad yung 1TB ko hehe

[Timithekid]

There is actually a thread here that discusses setting up and I think you would get more replies if you post there, but to get you started,  people more often than not build around the speakers.

Sir, hindi kaya 720p kasi ang tv mo kaya hindi mo ma differentiate or di mo makita ang 1080p resolution?

Is 720P good enough for a 42 inch screen ? YES

[AC]

sa 55.. 1080p tv... still hard to tell for me... napapansin ko minsan.. not as good as 1080p.. but yet again.. meron mga 720p movies.. akala ko 1080p.. ganda kasi..

Is 720P good enough for a 42 inch screen ?

Yes, IMO it's exactly that.. good enough. Pero kung hindi naman masyado malaki ang difference sa price, I'd go with a Full HD TV.

[Stagea]

For someone with 20/20 vision (1 arcminute spatial resolution) and a 42" screen, the difference between a true 720p panel and a higher res panel should be noticeable from 8 feet and closer (if one knows what to look for).



With 1024 x 768 panels becoming more common: Someone with 20/20 vision should be able to perceive a difference at 10 feet between 1024 x 768 screens and higher res panels.

The difference is more visible with slow-moving text and other high contrast material. With video that has smooth gradations, it is far less perceptible (and even if you see the difference, it may not bother you).

The resolving power of the eye is higher than what most people think. It's just that different people process the visual data differently. It's best to compare for yourself.

Question is what is your comparison with 720p and 1080p? Is the 1080p you are comparing is a real 108p bluray or just a 1080p encode? If you will notice the encoded 1080p is not real 1080p most of the time encoded 1080p is just  1920 X 800 and so on not 1920 x 1080p. So if you compare the 1080p encoded to the 720p you can't see the difference since most of the time their difference is on size and video bitrate. The encoded 1080p is slightly with higher size and video bitrate. A real 1080 in mkv is the remux one with same video bitrate as the bluray so this should be the one you will compare to a 720p or the bluray disc itself. For example you the total recall 70p to a 1080p encode and real 1080p.

720p
ViDEO BiTRATE...: x264 L4.1 High @ 5409 Kbps
RESOLUTiON......: 1280 X 534

ViDEO BiTRATE...: x264 @ 10352 Kbps

Real 1080p / Bluray
ViDEO BiTRATE...: 19404 kbps
RESOLUTiON......:1920 x 1080
Main Movie Size:  24.5GB

If you can see on the spec above the real 1080p has a bigger size than the 720p 3x the size and the video bitrate. This is also like others like on using cable or on the audio side flac and other that hey can notice the difference but not all can observe the difference. Some don't bother to see the difference as long as they are viewing a high definition not a dvd type movie. So if you play the 1080p encode on a 720p TV you wont it will fit and you can't see any difference because the real resolution of the 1080p encode is bit higher than 720p it 1920 x 800.

1920 x 1080 VS 1920 X 800
AFAIK the removed pixel count (removed 280p?) is the black bars .  anong details ba ang nawawala dun sa black bar?

alisin mo si blackbars mag stretch si picture
hindi mag 1:1 ang pixel nyan

medyo mali yata pagkaka-sagot ko.
1080p is the whole screen diba. 
alam ko gawa nung encoders eh yung blackbar tinatanggal nila, pero pwede parin ma-view with black bars pero mas maliit yung file.  but still @ 1080p.

here we go again with "fake" 1080p vs. "real" 1080p

false.

original aspect ratio still maintained, pixels are still mapped 1:1 even after removal of black bars.

what makes "remux" better than "encodes" is the higher bitrate (no discared information from the original-studio-master-to-blu-ray encoding)


BTT:
higher pixel count is a waste if you're eyes are unable to resolve it. with all things being equal, 720p (screen resolution and/or program material) can be good enough on a 42" screen if you sit far enough. sit too close and you might start to see the limitations of that resolution.

this is what i meant bro
diba discarded ang "black bars"

Nope encoders does not remove black bars. Like CHD and framestor group and if you will see my sample not only resolution is decrease but video bitrate also 720p and 1080p encode. AFAIK when you decrease the video bitrate the PQ detail is affected.

+1

Remux is the original video and audio no encode has been done so still the PQ is like bluray. If you will check the video bitrate of the remux and bluray they are the same.

Why they will make such a big file if it will same PQ as the 5GB or 10GB with lesser video bitrate.

sige na nga, double blind test nalang natin

Its on the eye of the viewer if your don't see the difference good as you are watching the orig bluray. As for me i see the difference as i have 20/20 vision pa din as per last checking of my eyes.

Lols bro yung kasing video bitrate 720p 5409kbps vs 1080p encode 10352kbps vs bluray/remux 1080p 19404kbps ang laki ng difference yan kasi base ang PQ.
