i was reading up about a tv i was going to buy and noticed that it said it wasn't full hd but said it was 1080p, i thought 1080p was full HD but obviously not so what is a full HD tv. Also while in the shop i noticed a big differance betwenn the LCD and plasma screens and i thought the plasmas were better but it didn't look that way to me the picture looked much darker and not as good on the plasma, this goes for all makes in the shop

1080p is full hd, im sure of it! 1080i is interlaced, and 720p is the next one down. standard def is 500-and-something.

I supposed "FULL" HD is a marketing thing. some monitors run at higher resolutions so no doubt broadcasts and tv's will follow making them the new full hd

yeh basically 1080p tv's have 1080 lines from top to bottom so when you run a 1080p signal it runs at a 1-1 so its as perfect as your going to get.

 

1080i tv's have 720 lines but has technology on board to upscale the image to what it thinks a 1080p signal looks like

i have a panasonic viera 42" that is 1080p but reading on a review site it said it wasn't full HD which i dont get

i have reread the review and it says my TV is 720p which is wrong cause i watch/play everything in 1080p, but it says "its not native 1080p"?????

Yep definately full hd is 1080p you can't get any higher.

 

Plasmas aren't that great tbh, they do have slightly more organic colours but i'd wait for OLED technology to come out. Thinner, lighter tvs with better lighting, wider viewing angles and the colours are out of this world (i've got an OLED display on my phone) :D

what model tv is it?

TH42PX70B here is the site

http://www.reevoo.com/reviews/mpn/panasonic/th42px70

The "i" or the "p" at the end of the number means interlaced or progressive scan. The number is the number of horizontal lines on the picture.

 

A picture on a UK tv updates 25 times a second or at a rate of 25Hz. Reason for this is that our mains frequency is 50Hz and TV's used to get their timing from the mains. Back when TV was young the technology wasn't good enough to update the picture at 50Hz so what they did was take the even numbered horizontal lines and the odd number horizontal lines and update them both at 50 times a second one at a time so you end up with a complete picture at 25 times a second. This practice of doing a set of lines at a time is called interlacing.

 

Progressive scan is a term that comes from computer monitors and means that the all the lines are updated at the same time at whatever speed the signal is updating.

 

Progressive scan requires better equipment as more is happening at the same time but the picture is better.

 

So 720p is progressive scan at 720 horizontal lines of resolution (HD-ready)

1080i is interlaced at 1080 horizontal lines of resolution (Full HD)

1080p is progressive scan at 1080 horizontal lines of resolution (Full HD and better than 1080i)

 

720p Televisions can normally play 1080 signals but the signal is down-scaled to 720p or 720i

 

Xbox, PS3, Bluray and PC/Macs can do 1080p

Freesat and Sky HD do 1080i

Nintendo Wii is 480p or 576i

Regular TV is normally 480i

yeh it is hd ready which is 720, the funny thing is the panasonic hd ready tv's display your running 1080p when you have a correct signal ie ps3 etc but your not as the tv does not support it, my old plasma was the same, think i had the 60 model

 

i have the pz70 now

so my tv is only 720p really

so my tv is only 720p really

 

no its 1080i which means it simulates 1080p, still a cracking tv and dont forget most ps3 games are only in 720, sky hd is only 1080i so unless your playing blurays then your getting the best picture possible anyway :)

i do play blu-rays and im a bit pissed cause i bought this TV as an upgrade cause my old one wasnt 1080p and this had a big sticker on it saying 1080p as most do but when you look there isn't that many that are true 1080p

any opinions on this i'm thinking of getting

Sorry Kirbz but the TH42PX70 is a 720p set which means that it the max resolution it can display is 1024 x 720. A 1080i TV have a resolution of 1920 x 1080. I was thinking of getting one myself as they got rave reviews but the 720p thing put me off. To be honest, i've been told that unless you're going to about 50" you can't really tell the difference between 1080 and 720.

 

The reason you can see a 1080 picture on a 720 tv is cause it reduces the number of horizontal lines from 1080 to 720 before it displays them.
