How can I set the HDMI output to 1366x768?

Question

1024x768 is an option from the ATV to the HDMI Port.
But my TV is 16:9 and has the resolution of 1366x768 when I plug a computer into the HDMI port.
If 1366x768 is not currently possible from the ATV, could apple be so kind as to add it,
thanks,
Jonathan

1366 x 768 is the number of pixels in the screen, it remains to be seen whether it's a resolution the TV will accept, but it likely will since it appears to accept 768 lines of resolution.
However, the Apple TV outputs several widescreen standards for HD and ED, it also supports some graphics display resolutions, presumably for older non-wide screen projectors. The problem with graphic display resolutions is that there are many of them including non-standard resolutions.
The Apple TV supports Full HD, HD and ED, it also supports VGA, SVGA and XGA, your TV has a pixel array that would fall into a classification known as WXGA which is non-standard to begin with but also includes 4 other resolutions which are also non-standard, WXGA is primarily a 16:10 aspect ration before a 19:9 one, so whilst you may not like it, the pixel array used by your TV has been pulled from a hat in terms of standard resolutions.
AC mentioned something above which I'd like to expand on:
Panels will always give sharper pictures when displaying output at native resolution, which is what you are trying to achieve.
This is essentially correct but only part of the wider picture so far as your TV is concerned, (it isn't actually what you are trying to acheive). Content doesn't (widely) exist at 768p. Generally speaking you will only have content at 480p, 576p, 720p or 1080p, so something needs to convert this to 768 lines of resolution for your TV.
There are two devices in the chain that can perform scaling, the TV and the Apple TV. In different scenarios this can lead to one or the other device doing the scaling or in some cases both. When setting up a system, one should note the capabilities of each device and try several options (if they are available) to get best results according to which device is best at scaling.
However given your observations, it is obvious that the Apple TV is much better at scaling than your TV, which given the pixel array on your TV is a little absurd, since very few devices (DVD players etc) will offer 768 lines of resolution and your TV is always likely to be doing some scaling.
Whilst you may not like the terminology of being pulled from a hat, your TV's pixel array is a non-standard size. There are as mentioned previously many non-standard sizes, to make them all available on the Apple TV just because some TV's perform inadequately when scaling isn't realistic.
