: 1080i to 1080p Upgrade?

2008-01-29, 12:38 PM
Newbie here....(hopefully this post is in the right forum thread)

I am a recent owner of a PS3, and have found my movie collection of Blu-Ray movies increasing, picture quality looks fabulous on my Toshiba DLP 52HM84, however its only 720p/1080i HDTV, which I got over 4 years ago. My question to you all is, am I missing out on the new "1080p" wave of Full HDTV LCD/Plasma's. I am thinking of buying another TV for the household, and don't want to blow my budget, since I already have a solid DLP TV. I am looking at the Samsung LCD LNT4061, which comes with all the bells and whistles. (3HDMI slots 1080p resolution, USB ports), etc.....

Is this a worthy upgrade for me? or should I stand pat, and wait tell the newer technology comes out, but at the speed of tech, that is probably pointless. You know what I mean?

Basically, am I going to notice my Blu-Ray Movies, in better picture quality if I go with this upgrade. I know there are better LCD's out there then this Samsung, but its on Sale, and the size (40") is just about right for my room conditions.

Thanks again, love the site......any info would greatly be appreciated.

If your DLP set is properly calibrated, I doubt you would notice much of a difference.

I think you would be disappointed going from a 52 " to 40" television. The screen would be about 30% smaller.

Your DLP is 720P, not 1080i, see:


The 720 (or equivalent) vs 1080P discussion has been held on this forum many times. See:


Also, see the following post, useful for newbies to the forum:


By my calculations a 40" screen is roughly 40% smaller than a 52" (a 52 is roughly 70% larger than a 40 - by area, which is the typical calculation)

Not sure why you would contemplate going from a 52" to a 40" TV in the first place.

Have you got wall hanging fever or is there pressure from your better half? :D

If you aren't going bigger than it's not worth it since your current TV is still a good one.

Again thanks guys,

As I stated, I personally think my 52" DLP is too big for the room I got it in at the current moment, and I plan to move that to the basement, (games room which doesn't have a TV at the moment) and get something that is more "fit for the room" I currently sit in, upstairs. I agree that dropping down to a 40" will be drematic, but the price can't be beat for that model, and I don't want to "blow my budget" since I already have a solid TV,

I might be conterdicting myself, but.....damn this technology world can be frustrating....LOL!!!! :)

This should make your decision easier....40" at proper viewing distance, you don't really need 1080p...eyes can't tell

At small panel size...the tougher question is LCD vs Plasma :~)

wozman, what are you talking about? If you're moving the 52" downstairs and buying a new set for your upstairs room then why are talking about upgrading? Your just buying a new set so why the whole discussion about the DLP and the 1080i vs 1080p?

I agree I kind of gotten myself in a pickle here. I just don't know what path to go. I want to add another TV - LCD/Plasma to the house, to complement my DLP Toshiba 52" However I don't really want to blow the budget out of the window, (I spent about $4000 4 years ago on the 52" TV) crazy.....

A) add a 46" FULLHD 1080p $2500 or so, and use it in the living room, and move the 52"DLP downstairs to the "games room"
B) add something smaller, 37"-40" LCD and move the larger 52" to the basement games room.
C) leave the 52" where it is, and add something smaller downstairs, to house my PS3 etc....in the games room.....

Either way, I would like to add another TV to the household. but don't know which direction to go. I am getting really into the High Def, Movies, (Blue Ray) with my recent purchase of a PS3, that is why I am asking should I go with the new wave 1080p tech. to complement that.

Thanks again.....hopefully this clears things up.

As has been said, you won't notice a difference between 720p andd 1080p with a 40" tv, especially at a normal viewing distance. But, since you don't know where you might want to put that tv some time in the future, you might as well get one that's 1080p. And if you want to notice a difference now, with BluRay, etc. then get at least the 46".

i heard that there isnt any difference between 1080i or 1080p on a plasma tv? is this true? i mean there obviously is a differnce in what it is. but display wise, will there be a great deal of difference seen when using ps3 for games/blu ray? someone on these threads was saying that plasma is all progressive and converts 1080i images into 1080p.

The answer is, "it depends".

- are we talking about a 768P or 1080P plasma?
- what is the source of the 1080i 1080P signal?
- It is true that there is little noticeable difference between an HD-DVD converted to 1080i, sent to a 1080P TV, vs a 1080P signal.

See the second link in post 2.

we are talking about Samsung 42" HPT4254. Display Capabilities 480i/480p/720p/960p/1080i. is it good enough to buy this for a ps3 and mostly SD tv reception. i sit about 7-10 feet from the tv. i am curious if on this plasma i would notice that much of a difference, especially through the ps3 for blu ray capabilties. am i missing a whole lot from not getting a 1080p? would it be better to save some money and buy a good quality 720p tv in my case over a 1080p?

On a good quality 42" screen, I would doubt you would notice a difference outside of 4 feet.

You really need a larger 1080p display for your BR discs (the 52" is too small besides being a lower resolution). If you have a light-controlled basement your best option by far is a 1080p DLP projector which sells at $2400 street at this moment. Smaller 1080p flat options (58"-65" LCDs or plasmas) are outside your price range at this moment. For that you need to wait 1 year.
