i'm pretty knoledgable about pc's, but not when t comes to tv's and hd stuff... i've just oredered a Samsung LE32M86BDX 32", but don't have a bluray or hd dvd drive, but was wondering whether i could upscale the definition usign my pc... or whether it can do any other tricks?...

also, the resolution of the tv is 1366 x 768, and it supports 1080i HD, and i thought you needed a lot higher resolution to display that kind of high defeinition... so what kind of quality am i likely to see if i plug this up to my pc?..
 
If you can get 1:1 pixel matching (1360*768) then it will look like a normal LCD monitor. If you have to set it to use a HDTV format i.e 720p or 1080i the the TV will scale the picture and use overscan which looks fairly terrible when using Windows.
 
so does that mean that even though the tv says it is 1080i, it just scales it down again meanign it doesnt really display that quality?..
 
Each 1080i frame consists of two fields of 540 lines interlaced together. To be very simplistic your TV has 768 lines which is greater than 540 therefore it will display 1080i without reducing quality (although some sets will seem to flicker more than others).
 
form a pc, the optimum resolution is the native resolution of the display panel, 1366x768 in your case. 1360x768 is also acceptable. Reason being, your pc is capable of far better scaling than the display is:)
 
so whats the difference between types of HD aka 720i , 1080i and resolution... so i would get a better picture by getting a 1080i source aka bluray, and then scale it down to the display, rather than upscaling a standard def dvd.... ps what definition/standard resolution is standard dvd's?
 
For TV formats the number is the total number of lines and the letter determines if it shows them all together or interlaced half and half.

576i normal TV 720*576 pixels 25fps interlaced=50fields per second

720p 1280*720 pixels 50fps progressive

1080i 1980*1080 pixels 50fps interlaced=100fields per second

1080p 1980*1080 pixels 50fps.

A progressive display will look better at any give resolution.

Your TV does not fit any of these exactly as all 1360*768 are dereived from the widescreen 16:9 version of the computer monitor res of 1024*768.

As James says the best possible quality is to output at the screens native resolution an let the software sort out any scaling, both nVidia and ATI drivers are better at it than any TV. I would never output 1080i from a HTPC the desktop will be blurry and overscan will put the task bar off the bottom of the screen.
