Viewing Distance Discussion Thread

[boboys]

I would love to get a plasma, but my living room a bit small, a bit less than 3 metres viewing distance, too near for a 42 inch plasma right?

So maybe get 37 inch lcd, just hope SD don't turn out too bad. Or maybe get a new house...haha

 

[alanchia67]

if you get full hd plasma, 3m is too far for 42"

 

[TsQ]

at 3m , 42" ok .. just nice actually.. u can google "viewing distance" and see those calculators.. most say 42" needs 10.50 Feet.. which is slightly more then 3Meter

 

[boboys]

So 42" should be quite ok for SD viewing at 3m? Hmmm...maybe should start looking for that Kuro or PV...instead of Samsung series.

hmm my room's sofa to my tv is ard 6 feet...n im thinking of getting a 46" full hd lcd..is the distance alrite?

 

[TsQ]

go a google search.. lots of guide on that ..

1920 X 1080 Question

Hi All,
I curious and hope someone can help:

If a 42" can display 1920 X 1080 lines and a 50" or 65" having the same, wouldn't the pixels be smaller on the 42" ?

Cheers!

 

[alanchia67]

yes you are right - the pixel will be smaller on 42" since the panel resolution (1920x1080) is constant. as such, the dpi will be different amongst the panels.

couldnt be. at 42", hd resolution is resolvable at max distance of about 5 feet. are you reading the correct chart?

perhaps you meant 480p? my response was full hd.

not too sure.. i think mine calculate do no consider HD or not.. just normal viewing distance according to screen size.

This is why we sit further for a larger screen.

this method is no longer valid. you need to consider the screen resolution.

I'm sitting less than 2 meters away from my 46" HD-Ready Bravia (distance measured from eye to screen panel).

oh n how is it? coz rite now im using a samung 32"...n it seems smaller by the day..haha

i choose my screen size based on my viewing distance, not the other way round

distance & pixelation (picture "quality"):
significance of screen resolution and viewing distance is on "pixelation". suppose you have two 42" same brand/model HD ready screens (1366x768), 1st at 5' and 2nd at 10' away. the nearer 5' screen will look more pixelated (lines becomes jagged, see less details, fine graphics become blurish, etc.) than the 10' away screen whose pixels are visually smaller even though actual pixel sizes are the same for both screens.

distance & viewing comfort (eye strain & headache?):
another important issue to consider is viewing comfort. supposed you replace the 5' away screen with full HD screen (1920x1080), picture quality will obviously improve. the issue now lies with comfort. when closer to the screem, our eyes have to cover a relatively wider angle and will become tired faster (may develop headache over time). this is because our eyes work under "pin-point" focus mode and they have to scan/hop around the screen to get a clear full picture. imagine watching a movie sitting at 1st row in a cinema, very tiring on the eyes. move further away and you will find more comfort for the eyes.

just my 2cts opinion

good advice.. as many ppl look at ur 1st poing and forget 2nd point... ie the classic one that we use to consider in days of CRT tv and projectors

 

[alanchia67]

that's the reason behind thx's recommended distance for particular screen size ignoring resolution.

LOL! When I first got this TV 2 years back my sofa was more than 2.5 meters away. Now it's less than 2 meters so the question is, why?

Because as time goes by my TV seem to shrink in size and I had to keep shifting my sofa towards the TV every month! Hahaha....

Mean telling u i need an upgrade!!!!

 

[alanchia67]

for full understanding of distance vs resolution vs display size, i'll suggest everyone read this first
