Hi Guys,
Quick question, if a plasma has a native resolution of 1024x768, can it output a true 720p signal?

Thanks.

Technically, yes. It will take the 720p signal and display it within it's native 768 resolution, thus eliminating overscan.

Not that it should matter anyway, considering that no broadcaster uses 720p.. unless of course you plan on using a games console.

Yeah, Xbox purposes. And I guess I've been reading up too much on HD-DVD and Blueray lately  :blink:

Just want to see how future proof my screen really is.

Current Xbox or Xbox 360?

Current generation xbox doesn't have many games that can do 720p.. unless of course you plan on using it as a Media Centre.

Hey. Let me get this straight please.

A native resolution of 1366x768 compared to a native resolution of 1024x768 would both show true 720p signal??

No difference because they are both x768??

I know, but we all start somewhere right??

Isn't there like a DUMB NEWBIE GUIDE website that explains video stuff like deinterlacing and resolutions/lines in very Smiths Chips plain English??

I mean most websites I've come across to try and learn more use too many abbreviations like "the MPAA will not allow this because of the simple fact that SCSS would be released before the RSNT would even be considered".

Cheers,
Ash.

Correct. The reason being is that the display with a native resoolution of 1024x768 uses what's called non-square pixels. That is, the pixels (horizontally) are rectangular.

Vertically, the pixels remain the same size as a display with a native resolution of 1366x768

btw, MPAA = Motion Picture Association of America

Thanks DavoNogo for the info. lol well i know MPAA do exist but wasn't aware who they were. As for the others, I made them up.

Just hate reading articles, webpages which mention a lot of abbreviations and don't explain in brackets (DAM I love those abbreviation explained brackets) what they stand for.

I'm learning, slowly but surely.

Yeah, good info clearly explained by DavoNogo. Thanks.

Me, I'm having trouble with DAM (is this another abbreviation?)

I hate to tell you this, but 720p is 1280 x 720 resolution progressive - so, no your XGA res panel cannot show 'true' 720p, it will just show it in the 1024 x 768 field you have.
Never really could understand the 42" Plasma XGA widescreen resolution thing - LCD's are all native widescreen 720p ready, but only the bigger 50" plasmas are true widescreen 720p.

Well sure if you want to be specific, it will show a 1280x720 image within the 1366x768 or 1024x768 display, with black bars around the image, but due to overscan, you'll never see the black bars.

Point I'm trying to make is that you won't lose any vertical resolution. They would not design and manufacture a display that couldn't display 720p properly then make it mainstream. The US market practically love 720p.

Think of it this way.. have you ever seen an ad with huge black borders surrounding the image? Well, chances are, the ad will be a set resolution within the 1440x1088, 1920x1080 or 720x576 resolution that the broadcaster is broadcasting at. That is how it will look like when you display a 1280x720 image within a 1366x768 or 1024x768 window, but like I said, overscan will ensure you will never see those black bars. That is of course unless you run the resolution at the wrong timing, in which case, you'll either make the image too big or too small (ie. you'll get black bars)

If you want to future proof your purchase specifically for games then you might want to hold out.

PS3 is coming out with a blu-ray player that will present 1080 vertical lines so, with the assumption that the games developers are on board, you will be getting native 1080i/p games coming out with it.

Hold off? Already have my panel, extremly happy with it, just curious about its capabilities.

My query was really, is 1024x768 HD? As 720p seams to be the threshold for HD.

not sure if I understand this properly, but if a panel only supports 720p at 60hz then is it correct that it will only be able to display a broadcast 720p signal with black bars? (As Aus broadcasts are at 50hz)  

Anyoneknow what timing the xbox360 will use for its 720p signal (ie 50hz or 60hz or a choice of either)?

There is no chance of knowing what the Xbox 360 support will be like.. At the moment it's all just speculation. You'll have to wait until someone with a HDTV can get their hands on an Australian Xbox 360, which will more than likely occur closer to the console's release date (early next year)
