why does a 1920x1080 (1080p) wallpaper look bad on a 3D HDTV used as a monitor?

I have done some research and from what i can see a 1080p still frame is about two megapixels in quality. After researching spatial resolution my understanding is that for 1920x1080 to be displayed accurately it would have to be displayed on a 19" x 10" screen? So does that mean my wallpaper looks lame because its having to stretch it to over double the size on a 47" HD screen? now i have tried to use a 3840x2160 wallpaper but it didn't fit the screen. So i resized it in photoshop (but wouldn't this knock the resolution down (i mean quality)? As you can see i'm confused and not very aware of what i'm talking about...in short i guess my question is.... How do i get a wallpaper to look good on a large (47") 3D HDTV being used as a monitor for a computer?

extra info:

I do have a hdtv card that I use to watch tv (looks great from a distance!) when using tv as a monitor viewing distance is about a 70-100cm
SO:

If I was to take a larger image i.e. 3840x2160 and open it in photoshop, then create a new 1080p size image and increase the dpi to say 200 and then free transform the large image to fit the 1920x1080 canvas would that make an image look sharper by cramming more dpi into a smaller canvas? or am i completely off there?



Answer
Its just the size of the monitor is very large.
With a 47" screen the dots per inch will be relatively low.
It will look fine from a distance - but up close the pixels will be quite large.

A high quality print will be anything up to 1200 dots per inch.
1920 pixels would be less than 2 inches at that resolution - so at 47" diagonal that is not going to look very sharp.
Your DPI on your monitor will be relatively low compared to a 1200DPI photo print.
It will even look low compared to a 300DPI print.
There is nothing you can do about this. Its all to do with the available pixels per inch.

EDIT: Just done some maths on a 47" diagonal screen and it turns out that your DPI is around 36DPI.
That's pretty low if you are up close and expecting sharp results.

What is better? PS3 or Xbox 360?

Which is better having to do with everything the game systems have?


Answer
i would go for the ps3 for these reasons: It has a great built in web browser. also has built in wifi so u wouldn't need to connect it directly to an Ethernet cable is you have a wireless router.
The PSN (playstation Network) is free to all playstation owners, and is great for online play. also the psn has the playstation store which is great for downloading free demos, videos, trailers,wallpapers and themes and psn games which cost a little doe. also the ps3 has a built in blu ray player for playing the highest quality movies on the market. an 80 gig system makes for a great central entertainment piece, can store movies, music, pics and games. Wanna really get set up and get the full experience, then get an hdtv and 5.1 surround sound!
The xbox 360 has xbox live which costs 50-60bux a year. the 360 does not have a web browser yet but might be added in future updates. if you buy the elite system you will get built in wifi but if you don't you will have to pay and extra 100-120 bux for it. When it comes to games xbox does have halo, but you can only have so much fun with 1 game, ps3 has some great games and some great games on the horizon(metal gear solid 4, gran turismo 5, resistance 2, killzone 2....)
2008 is definitely gonna be a great year for ps3, tons of great games are coming out... and Home too, look it up.
i traded in my 360 for a ps3 near launch and i don't regret it. but the final decision is up to you of course. good luck, (:
