Hi.

Can somebody explain plasma resolution to me? The majority of 720p panels have a resolution of 1024x768, wheras 720p is officially 1280x720, how can they display it without scaling?

Cheers
 
they cant. its about as simple as that lol. any input that any panel wants to display has to be scaled if it isnt in the panel's native resolution.
 
Are you sure you’re looking at the resolution of the set not the computer resolution? As most seem to and is the same for mine list it like this;

Resolution 1365 x 768
Computer Resolutions 1024 x 768 (XGA) 640 x 350 640 x 480 (VGA) 720 x 400 800 x 600 (SVGA)



Edit/ Just looking at a few specs of plasmas and it seems the majority of the 42' sets are indeed 1024x768 and the 50' are 1365 x 768 :D
 
Yes, majority of plasmas have "square" resolutions and "rectangle" pixels hence the confusion between a widescreen tv and "square" PC monitor of the same resolution.

So they still have to scale 720p content? That puts me off a little.

Yes, up a few pixels. Unless you feed a PC to them at 1024x768.

The scaling will make a negligible difference in picture quality though.
 
I'm talking more about the horizontal scaling, as 1280 vs 1024 is a fairly large differance on 37" or so.

just a minor correction - they have to scale 720p down to the native res, not up:)

well, 720p lcd's have to scale up instead of down, as their resolution is actually 1366x768. in all honesty, its better to scale down that it is scale up - you cant recreate data thats been taken away. in the respect, 1024x768 plasmas are better equipped to deal with 720p, and its generally the case that plasma deal with SD and upwards far better than lcd's do.
 
Hmm. Am going to have to think about this when I buy in a few months. Worries me a little not having the full res.
 
well, what about if you want to play bluray or hd-dvd's? you wouldnt have the full resolution on either of them. barely 50% of it, infact. you have to remember that there isnt actually much 720p content around. sky+ and virgin V+ are both 1080p. blurays and hd-dvds are 1080p. consoles will work in 720p yes, but actual film material? there isnt much of it lol

Good point.

The majority of it's use will be games and TV shows upscaled via ffdshow on the PC (more than likely better than TVs scaler). Screenburn through gaming is a concern, however.
 
james.miller, good spot on my error. I'm going to correct one of yours now :p

SkyHD is actually all broadcast in 1080i. The box then alters this to other resolutions, 1080p isn't one of them though.

Do you game for long periods at a time? We have a Wii on the 42" Panasonic Plasma but never play for more than 2 hours at a time and have no issues. I have seen Xbox360 dash burned into a few customer's plasmas though.
 
Occasionally yes I, with friends, will have sessions which go on for 3 or 4 hours, but nothing like ALL DAY.

No they're not, they're both 1080i, unless I'm very much mistaken.

As for plasma resolution, I find the 1024 horizontal res of most 42" plasmas a total scam tbh and technically not HD at all. I'm amazed they're able to get away with labeling such screens as HD Ready simply because they have the requisite vertical resolution yet the horizontal is so poor.

Oddly, if you step up to 50", most plasmas do seem to offer the increased horizontal res of 1366, which is more in line with LCDs and what I'd expect of an HD ready screen.

Main reason i got an LCD over Plasma for the fact that the LCD is true 1080p. Even though the LCD doesn't have as good motion handling and more ghosting than the Plasma on SD stuff, its a price you need to pay for 1080p imo.

dont post crap

There are LCDs that are 1080p

but there are LCDs that are not

same applies to Plasmas as well. Its just (arguably) the best plasma brand, pioneer. That only makes 1080p plasmas in 50" and above

but Panasonic have the fully 1080p HD PZ range. So its a brand limitation, not a technology limitation.
