Well, we are starting to get back on our feet financially and are in a position to consider this again. I have found a very nice deal on two televisions and am curious as to which size would be recommended. Again, viewing distance approximately 14-feet and we are still looking at mounting it above the mantle (the height would work very well for reclined viewing). Recall, we currently have a 30" 1080p tube television with all standard definition DVD player etc and will not be upgrading those items for a while...

47" 1080p

or

50" 720p



Thanks...

At that size you need 1080p more than you need 3" of screen size, so if those are the choices (all else being equal) I'd say 47" 1080p.

Are these plasma or LCD? Plasma screens are very reflective - LCD screens are not.

Good point...

the 1080p 47" is LCD

the 720p 50" is Plasma

Hi twmattox -

Sorry to "disagree" w/ akirby - but- you certainly do NOT need to worry about the 720p set - that will be so very far removed from your eyeballs that you will NOT benefit from a 1920 X 1080 - full HD - set at all !

That's for 58" - 60" and larger HDTVs w/ also use of a Blu Ray / P.C. / Games Console / etc., involving "Up Close" seating !


Glare will also be "moot" due to that sharp inclination or tilting above the Mantle downward toward those recliners.

This set ? - - - http://www.amazon.com/exec/obidos/tg/de ... R&v=glance

Excellent @ $932, no tax except NY + KY plus, safe, guar, 2 person del'y unpacked & set atop your temporary TV Stand !!

Here's a # 3401 tilting wall mount that I've used w/ great success, since it allows for many lags or - in your case - anchor bolts - with it's 45" long wall plate - (scroll up for image) - - - - - http://www.monoprice.com/products/produ ... cification

Everyone should have access to a "tie breaker" for themselves in order to make up their own minds - - - this IS an old discussion BUT it also contains added references which try to explain What the human Eye can & can NOT discern . . . . take you time & enjoy ! One about "Contrast Ratios - Huge Numbers" . . . and the other about the 720p vs 1080p affair . . . .

Careful, Eli. There is no absolute answer about whether someone will or will not see a difference between 720 and 1080 on a 50" set at 14 feet - some will even if most won't.

There is also no way you can say whether they will have glare problems or not.

Let me put it this way - if it was me I'd take a 47" 1080p LCD over a 50" 720p plasma every time, all else being relatively equal. You're guaranteed to have the best picture (in terms of resolution) and no glare. This could be important down the road with Blu-Ray, etc. Maybe if it was a 42" LCD, but there's not much difference practically speaking between a 47" and 50" screen.

What concerns me about the 1080 set is that we went from a standard aspect ratio 27" tv to a 30" 1080i set a few years ago. Though the 30" set is technically larger...the portion actually used is smaller than our old 27" tv. Some stations will use more of the screen than others...but for the most part, this larger tv seems smaller...

' Morning akirby !

Overslept for first time in a long while . . .

No contest whatever with your points! . . . I, too, strongly believe that after it's "all-said-and-done" no one should buy NOW any new HDTV @ less than 1080p ! {excluding a second, small 42" bedroom set, of course } . . .

BUT - do recall the special problems / attributes associated w/ this application . . . . only O.T.A.-HD for the very limited channel availabilities, that HUGE 14 feet viewing distance, the absolute need of keeping the available HDTV budget in mind, the improper mounting most-of-all, etc., etc..

It sounds very ominously like " twmattox " may have been exposed to a wretched "Vizio" 47" because of it's low initial pricing ! Heaven forbid . . .

There IS no adequate size LCD or Plasma display even available for that distance for proper "HD" immersion / effects / appreciation at all ! That would require a Projection set onto a completely-flat screen !

It's going to be simply a replacement TV set, w/o any HD effects at all . . . so, as was already posted, NO Blu Ray Player now or in future is needed or should be planned.

In the .. 47" .. vs .. 50.. " issue, he really needs to INCREASE - never go down in size to "fit" the available, proposed budget!

In terms of area viewed, there IS a huge difference going from his 47" to a 50" - - and, better still - - a 52" LCD" most assuredly ! In-point-of-fact, about 13% [50"] and a great 25% { 52" }!!

FAR better to sacrifice the possibility of " .. seeing a pixel or two on occasion .." that to have such an unsatisfactorily-small display that they WILL wonder why they spent the monies / changed at all !

Hi twmattox . . .

You HAVE exactly "hit-the-nail-on-the-head" the very first time !

ALL switching from CRTs to any new 16:9 set DO experience that very same phenomena - " IF " they don't understand that these new HDTVs literally ARE 25% smaller in their vertical display dimension !

To ONLY stay the same, one must increase by ~ ~ that % - I.E. - in your case, that 27" CRT should have been replaced w/ at the minimum a " 34 " - and since those aren't made, a 37" LCD.

What to buy and where

Post by rml »

If you can control the light in the room at all, I'd get a plasma; if not, an lcd. As for resolution, unless you watch a lot of sports on abc and fox (which broadcast atsc at 720p) I'd definitely get a 1080p set, especially if you plan to eventually get a bluray player; 1080p prices have nosedived this year and are marginally more expensive than comparable 720p sets. As for size, I'd personally compromise a for a smaller 1080p over a larger 720p. But you need to take your tape measure to a big box store and look at plasmas and lcds with different program material (e.g., fast action sports, high resolution nature - look at the Planet Earth bluray) to see whether the picture size, resolution and quality differences matter to you. As to where to buy, only buy from an authorized dealer whether at at local store or mail order. If you find a model you like, check and compare Amazon.com, 6Ave.com, Buydig.com, vanns.com, and bhphotovideo.com. Crutchfield.com is reliable but tends to be pricier, more comparable to Bestbuy.

Good luck
