1080p in 1366x768

[LazlowsucksiloveslutS]

I am amazed that my 24 inch tv displays 1080p. When I hit info button on remote it shows that is now displaying at 1920x1080 p. And the video isn't stretched or anything like it happened when I watched 1080p movies on my old laptop.

 

That particular tv screen resolution is 1366x768. But how can it display a 1080p image? Is it downscaled?

For some reason xbox 360 sets resolution to 1080 p when I select optimal from display settings, there is even a choice of 1080i among others.

I just don't understand how it can be when tv resolution is 1366x768. Is it better to just play in 720p with this tv?

 

It would be cool if anyone can explain me this.

If technical specifications for the screen (available in the owner's manual and on the internet) specify 1366x768 as the screen's maximum display resolution, then a 1920x1080p source will have to be downscaled. I believe that this technically amounts to 720p rather than 1080p. It sounds to me like your TV supports 1080p as an input, but incorporates a built-in downscaler to adapt it to what sounds like the screen's maximum supported display resolution. Refer to the owner's manual or online specs for your make and model number, go to the Xbox 360's settings menu and select a supported 720p resolution and compare the display characteristics. Is the 720p picture, clearer, sharper, and more pleasant looking overall than the downscaled 1080p picture?

Your television is displaying the signal that is being input, not that is being displayed. It's common for fixed-pixel displays to accept resolutions other than the one that they display natively.

 

You are correct: The 1920x1080 signal is being downscaled. As you said, your TV has only 1366x768 pixels; it can accept a higher resolution, but a lot of the information in the signal will be lost.

I don't have a console, but if you are talking about the display settings of the XBox, it doesn't have any "knowledge" of the display that's being connected. In other words, the optimal setting refers to the XBox and it's rendering resolution--it doesn't have anything to do with the display being connected.

 

Unless you are seeing artifacts or alignment issues when outputting a 1080p signal from the XBox, I would stick with that resolution. Like I said, you won't be able to see all of the information that the console is generating, but at the same time the image should be smoother and less aliased than the 720p output. Also, the 720p output would have to be slighly upscaled if you want it to completely fill your TV's screen, which would reduce quality.
