I saw a chart here on the forums that someone posted after another user asked how far away he should be from his TV. There was 480p, 720p, 1080i, and 1080p. And then there was 1440p. What is that? Never hears of it.

Bonus points if you can tell me the difference between "p" and "i" (especially the difference in 1080i and 1080p)
 
1440p, or 2560 x 1440 was a marketing term coined (see below for said term) by I believe nVidia and DELL to place particular emphasis on playing games at resolutions higher than what's widely accepted as "High Definition". Why? Mostly to set a precedent with Quad-SLI.

I think it's referred to as XHD or XD, I forget which.

1080p (Progressive scan) has all of lines in the frame of an image drawn in sequence (i.e. odd, even, odd, even, odd, even).

1080i (Interlaced) has all of the lines in the frame of an image drawn in alteration (i.e. odd, even, even, odd,).

Where do you get 1440p tv's?

It's not an official industry standard, so you can't. You can however purchase PC monitors that support the resolution, although you're looking at screens the size of 26'' and above.

And they're not cheap.
 
Dell U2711 is the staple 1440p monitor, at least in this part of the world (I'm seriously considering getting one soon). The Dell U3011 is 1600p.

Obviously the issue with that res for TV/Video playback even 1080P video has to be upscaled. But because it's still a 16:9 ratio it's not that bad. 1600p on the other hand is 16:10 and can cause stretching or black bars.

1440 is also 1440x1080 which is 4:3(1.333:1) aspect ratio.

Some cameras use 1440 recording for HD and the pixels used are not square but 1.333 wide which will give you 1920x1080.

I will not upgrade to a 2560x1440 monitors, but i will wait for 4K.

^ The prices for those displays is ludicrous. :scared:

Amazingly they're cheaper here in Aus than in the US. Where you can pick a U2711 one up for around $700 delivered, U3011 are much more expensive (~1800), but can be seen on sale for ~$1200. Seems a lot though I did pay $1400 for a 32" 720P Bravia a few (maybe 4?) years ago....

I've always weighed up getting one, as I used to use a 27" Mac at work with the same screen res, and really liked the extra space it gave out. But realised it was an insane amount of money (Realistically, you could buy 3 half decent 24" for the price of one 27", or 4 half decent 1080P 27"s for the price of a 30"...). However, two weeks ago I saw the U2711 in person and the colours were just amazing, it's a stunning display (10 bit panel, I'm fortunate enough to have a Bravia with a 10 bit panel, with Deep Colour and xvyCC, the difference between that an my 8-bit Bravia is easy to see), and makes my quite recent 24" LG LED display look like junk. Definitely comparable to Eizo monitors (at least to me) I've used which are 3 times the price of the Dell.

You spoke way to soon ;)

New 36-inch Monitor From EIZO Packs 4096 x 2160 Pixels Resolution
With the current consumer PC display standard positively, definitely stagnated at 1920x1080 TV resolution, primed for Blu-ray movies and Xbox games modified for PC, the launch of every new PC monitor that crosses the 1080p mark is met with some celebrations. Display major EIZO's latest such creation is the 36-inch DuraVision FDH3601. This display sports a native resolution of 4096 x 2160 pixels.

The monitor likely uses a Sharp ASV panel with 170° viewing angles. Regardless, it's 10-bit, supporting 1.07 billion colors, is CCFL-illuminated with maximum brightness of 700 cd/m², and has 1000:1 static contrast ratio. The monitor also packs the Digital Uniformity Corrector (DUE), a feature EIZO has been working on for the last few years, that ensures perfect light homogeneity. Slated for a September 7, 2011 release in Japan, the EIZO DuraVision FDH3601 is priced at US $36,000.

I know that, foo'.

I was talking about your bit on the resolution. No one, at least no one I know or have talked to calls 1440x1080 "1440p". If anything at all, it'd be 1080i/p.

The dell is an IPS panel? I really need to get one of these, so hard to work on photos with cheap screens.

Lol at the 36 4K panel, that's a grand for an inch.

I think the next evolution is a higher input framerate for TV's due to 3D (they really need 1080p at 60hz), 4k is such a long way till the masses can buy it at a moderate price. And we need a global distribution for HD tv. Here in Europe it is still lacking, or you need to pay for it, and I am definetly not paying for the same channel in HD.

True on the 10bit bravias. Have one myself. Stunning fidelity for a TV

Grayfox, when someone states 720p, 1080i, 1080p, or 1440p, they're talking about vertical resolution. You're using 1440 with 1.33:1 pixels as horizontal resolution. Entirely different spec.

Vertical resolution is how many scan lines the can monitor produce. Horizontal resolution is how many pixels can be resolved across any one of those scan lines.

That's why Terronium is "arguing" with you. You're misusing the 1440, applying it in the wrong direction. It's MUCH easier to have 1440 pixels horizontally than vertically.

Besides, 1440 non-square pixels may fill a 1920-sized horizontal space, but it's not 1920 pixels, it's still 1440.
