Hi
It is unlikely the TV will show this resolution as it isn't a standard HDMI resolution, if it does accept the resolution, it is just as likely to enlarge it to a slightly higher resolution as a TV wants to overscan, i.e. chop some off the tops and sides.
Well they would if it made any difference, but TV's don't generally as a rule support 1 to 1 pixel mapping, you need a computer monitor for that. Of course even in that case the picture is still upscaled, just by the computer. Do you think a computer or super expensive graphics card will be any better at upscaling? I doubt it, which is why we all go mad for mega pixel camera's as even with the most expensive and powerful PC you can't add any detail just by increasing the pixel count, and that's on very fast powerful computers that can take as long as they want doing it!
But that is still two lots of upscaling, you are taking real pixels and diluting them with lots of false pixels to get the extra resolution. Your TV then takes some of the real pixels and a probably a lot more false pixels then upscales and dilutes the real detail even more.
Upscaling isn't difficult to achieve. Yes some machines can use all sorts of clever tricks to do a very slightly better job on certain types of footage, but it's only slightly better, not enough to notice when you sit back on the sofa. The chip inside your TV is perfectly up to the job.
Yes I would say so. Of course if you have needed to buy new equipment that comes with HDMI then use it by all means, but don't re-purchase all your standard definition equipment again just because the latest buzz word is "upscale", it's all marketing is what we are saying.
Having a look in this forum we see no posts from people who have got HDMI on standard definition equipment shouting about how brilliant it is, plenty are wanting it, but those that have then got it seem rather underwhelmed and silent on the matter.

Er, if I feed my PC's output at 1360x768 over HDMI to the LCD TV... and the LCD does 1:1 pixel mapping... err... no upscaling needs to be done

Certainly recording devices based on Linux should be able to upscale and output at this resolution (?)

If your upscaling device is any good, then inputing 720p to the LCD TV would mean that the TV would only need to upscale a small amount (to 768p) as opposed to badly upscaling 576i/p (SD DVD player, for example) to 768p...

Is the conclusion that the best connection is the one for which you already have a lead?
